Antenatal sonographic diagnosis of epignathus at 15 weeks of pregnancy. (1/82)
Epignathus is a rare, benign, congenital teratoma of the hard palate. Most of these teratomas are unidirectional and protrude through the mouth. Hence, the prognosis depends on the size of the tumor and the degree of face distortion and airway obstruction that it causes. However, some epignathi protrude bidirectionally, involving and destroying the brain tissue, resulting in a poor prognosis. This report presents a case of ultrasonographic detection of a bidirectional epignathus at 15 weeks of pregnancy. (+info)Basal cell adenocarcinoma of the palate with squamous metaplasia. (2/82)
Basal cell adenocarcinoma is a rare salivary gland tumour, especially in minor glands. The clinical, histological, and immunohistochemical features of a case involving the palate are described. Formalin fixed, paraffin embedded sections of the tumour were examined in haematoxylin and eosin (H&E) sections and also using immunostaining for cytokeratins 7, 8, 13, 14, 18, 19, vimentin, muscle specific actin (HHF35), and laminin. H&E sections showed that the tumour was composed mainly of basaloid cells and a striking feature was the presence of squamous metaplasia. Neural invasion was also conspicuous. Immunohistochemical reactions indicated that cytokeratin 14 was expressed by all tumour cells and vimentin by all cells except those in the areas of squamous metaplasia. The remaining cytokeratins and actin were present in some of the tumour cells, while laminin showed discreet positivity around cell arrangements. The foci of squamous metaplasia and the immunohistochemical findings are helpful in distinguishing basal cell adenocarcinoma from other salivary gland tumours which show basaloid cells. (+info)Metastatic tumors in the sellar and parasellar regions: clinical review of four cases. (3/82)
Metastatic tumors in the sellar and parasellar regions are uncommon and rarely detected in clinical practice. We present four cases of sellar and parasellar metastatic tumors, which metastasized from distant organ in one case and extended directly from adjacent structures in three. Common presenting symptoms were cranial neuropathies, headache and facial pain. Invasion into the cavernous sinus was noted in all cases. We report rare cases of sellar and parasellar metastases. Also, we should consider the possibility of metastasis in these regions for patients who showed the above clinical presentations in systemic cancer patients. In extensive diseases, transient symptomatic relief could be obtained by direct surgical management, even in restricted degree. (+info)Polymorphous low grade adenocarcinoma with distant metastases and deletions on chromosome 6q23-qter and 11q23-qter: a case report. (4/82)
Polymorphous low grade adenocarcinomas (PLGAs) are thought to be indolent tumours that are localised preferentially to the palate and affect the minor salivary glands almost exclusively. Metastases to locoregional lymph nodes occur in only 6-10% of cases. Recently, two cases of PLGA with microscopically confirmed distant metastases have been reported. This study reports a third case of PLGA with histologically and immunohistochemically confirmed distant metastases. It is the first case with multiple pleural, as well as pulmonary parenchymal, metastases and metastases in cervical and paraoesophageal lymph nodes. In most cases, PLGAs are salivary gland tumours with limited potential to metastasis and a good prognosis after local treatment. However, the recently reported cases reveal that the tumour can give rise to widely spread metastases. To obtain more information about the incidence of distant metastases, periodic chest x ray examination during follow up is desirable. (+info)Granular cell tumor of the palate: a case report. (5/82)
Granular cell tumor (GCT) is an infrequent benign neoplasm, which Abrikosoff accurately described in 1926. GCT probably has a neural crest cell origin. We present the clinical and imaging findings in a 45-year-old woman with a GCT involving the palate. CT and MR imaging revealed perineural tumor spread along the greater and lesser palatine nerves. We emphasize the peculiarity of the palatine location and the perineural spread of GCTs. (+info)A case of NK/T-cell lymphoma complicated by a squamous cell carcinoma of hard palate during combination chemotherapy and radiation therapy. (6/82)
NK/T-cell lymphoma, which often shows an angiocentric growth pattern, is a distinct clinicopathologic entity highly associated with Epstein-Barr virus. The disease is characterized by a destruction of the upper respiratory tract, particularly the nasal cavity, palate and paranasal sinuses. Interestingly, NK/T-cell lymphoma is closely linked to a variety of complications, such as hemophagocytic syndrome, second primary cancer, sepsis and bleeding. Here we report a case of a 50-year-old man diagnosed initially as NK/T-cell lymphoma of the oropharynx and who developed a second primary carcinoma of the hard palate during combination chemotherapy and radiation therapy. (+info)Nontraumatic massive hemoperitoneum from melanoma metastatic to the uterus. (7/82)
We have reported a case of nontraumatic massive hemoperitoneum caused by melanoma metastatic to the uterus that was readily managed with surgery. We believe this strategy provided effective palliation, improved quality of life and potentially prolonged survival for this patient. (+info)Analysis of the tumour suppressor genes, FHIT and WT-1, and the tumour rejection genes, BAGE, GAGE-1/2, HAGE, MAGE-1, and MAGE-3, in benign and malignant neoplasms of the salivary glands. (8/82)
AIMS: Molecular genetic changes involved in tumorigenesis and malignant transformation of human tumours are novel targets of cancer diagnosis and treatment. This study aimed to analyse the expression of putative tumour suppressor genes, FHIT and WT-1, and tumour rejection genes, BAGE, GAGE-1/2, MAGE-1, MAGE-3, and HAGE (which are reported to be important in human cancers), in salivary gland neoplasms. METHODS: Gene expression was analysed by reverse transcription polymerase chain reaction (RT-PCR) in normal salivary gland tissue and 44 benign and malignant salivary gland tumours. RESULTS: Aberrant FHIT transcripts were found in one of 38 normal salivary glands, three of 28 adenomas, and two of 16 carcinomas. WT-1 mRNA was detectable in two adenomas and five carcinomas. Immunoblotting showed that WT-1 mRNA expression was associated with raised WT-1 protein concentrations. RT-PCR for detection of BAGE, GAGE, and MAGE gene expression was positive in two adenomas and nine carcinomas, but negative in normal salivary gland tissue. HAGE mRNA was found in two normal salivary glands, 11 benign, and eight malignant tumours. CONCLUSIONS: FHIT mRNA splicing does not appear to be involved in the genesis of salivary gland neoplasms. The upregulation of WT-1 mRNA in tumours of epithelial/myoepithelial phenotype may imply a potential role of WT-1 in the genesis and/or cellular differentiation of these salivary gland tumours. The tumour rejection genes were more frequently, but not exclusively, expressed in malignant salivary gland tumours than in benign neoplasms, although none was suitable as a diagnostic marker of malignancy in salivary gland neoplasms. (+info)Palatal neoplasms refer to abnormal growths or tumors that occur on the palate, which is the roof of the mouth. These growths can be benign (non-cancerous) or malignant (cancerous). Benign neoplasms are typically slower growing and less likely to spread, while malignant neoplasms are more aggressive and can invade nearby tissues and organs.
Palatal neoplasms can have various causes, including genetic factors, environmental exposures, and viral infections. They may present with symptoms such as mouth pain, difficulty swallowing, swelling or lumps in the mouth, bleeding, or numbness in the mouth or face.
The diagnosis of palatal neoplasms typically involves a thorough clinical examination, imaging studies, and sometimes biopsy to determine the type and extent of the growth. Treatment options depend on the type, size, location, and stage of the neoplasm but may include surgery, radiation therapy, chemotherapy, or a combination of these approaches. Regular follow-up care is essential to monitor for recurrence or spread of the neoplasm.
The palate is the roof of the mouth in humans and other mammals, separating the oral cavity from the nasal cavity. It consists of two portions: the anterior hard palate, which is composed of bone, and the posterior soft palate, which is composed of muscle and connective tissue. The palate plays a crucial role in speech, swallowing, and breathing, as it helps to direct food and air to their appropriate locations during these activities.
The hard palate is the anterior, bony part of the roof of the mouth, forming a vertical partition between the oral and nasal cavities. It is composed of the maxilla and palatine bones, and provides attachment for the muscles of the soft palate, which functions in swallowing, speaking, and breathing. The hard palate also contains taste buds that contribute to our ability to taste food.
The palatal muscles, also known as the musculus uvulae, levator veli palatini, tensor veli palatini, and palatoglossus, are a group of muscles in the back of the roof of the mouth (the soft palate). These muscles work together to help with swallowing, speaking, and breathing.
* The musculus uvulae helps to elevate the uvula during swallowing.
* The levator veli palatini elevates and retracts the soft palate, helping to close off the nasal cavity from the mouth during swallowing and speaking.
* The tensor veli palatini tenses the soft palate and helps to keep the Eustachian tubes open, which connect the middle ear to the back of the throat and help to regulate air pressure in the ears.
* The palatoglossus helps to form the anterior pillars of the fauces (the tonsillar fossae) and elevates the back of the tongue during swallowing.
A palatal obturator is a type of dental prosthesis that is used to close or block a hole or opening in the roof of the mouth, also known as the hard palate. This condition can occur due to various reasons such as cleft palate, cancer, trauma, or surgery. The obturator is designed to fit securely in the patient's mouth and restore normal speech, swallowing, and chewing functions.
The palatal obturator typically consists of a custom-made plate made of acrylic resin or other materials that are compatible with the oral tissues. The plate has an extension that fills the opening in the palate and creates a barrier between the oral and nasal cavities. This helps to prevent food and liquids from entering the nasal cavity during eating and speaking, which can cause discomfort, irritation, and infection.
Palatal obturators may be temporary or permanent, depending on the patient's needs and condition. They are usually fabricated based on an impression of the patient's mouth and fitted by a dental professional to ensure proper function and comfort. Proper care and maintenance of the obturator, including regular cleaning and adjustments, are essential to maintain its effectiveness and prevent complications.
Cleft palate is a congenital birth defect that affects the roof of the mouth (palate). It occurs when the tissues that form the palate do not fuse together properly during fetal development, resulting in an opening or split in the palate. This can range from a small cleft at the back of the soft palate to a complete cleft that extends through the hard and soft palates, and sometimes into the nasal cavity.
A cleft palate can cause various problems such as difficulty with feeding, speaking, hearing, and ear infections. It may also affect the appearance of the face and mouth. Treatment typically involves surgical repair of the cleft palate, often performed during infancy or early childhood. Speech therapy, dental care, and other supportive treatments may also be necessary to address related issues.
The soft palate, also known as the velum, is the rear portion of the roof of the mouth that is made up of muscle and mucous membrane. It extends from the hard palate (the bony front part of the roof of the mouth) to the uvula, which is the small piece of tissue that hangs down at the back of the throat.
The soft palate plays a crucial role in speech, swallowing, and breathing. During swallowing, it moves upward and backward to block off the nasal cavity, preventing food and liquids from entering the nose. In speech, it helps to direct the flow of air from the mouth into the nose, which is necessary for producing certain sounds.
Anatomically, the soft palate consists of several muscles that allow it to change shape and move. These muscles include the tensor veli palatini, levator veli palatini, musculus uvulae, palatopharyngeus, and palatoglossus. The soft palate also contains a rich supply of blood vessels and nerves that provide sensation and help regulate its function.
The maxilla is a paired bone that forms the upper jaw in vertebrates. In humans, it is a major bone in the face and plays several important roles in the craniofacial complex. Each maxilla consists of a body and four processes: frontal process, zygomatic process, alveolar process, and palatine process.
The maxillae contribute to the formation of the eye sockets (orbits), nasal cavity, and the hard palate of the mouth. They also contain the upper teeth sockets (alveoli) and help form the lower part of the orbit and the cheekbones (zygomatic arches).
Here's a quick rundown of its key functions:
1. Supports the upper teeth and forms the upper jaw.
2. Contributes to the formation of the eye sockets, nasal cavity, and hard palate.
3. Helps shape the lower part of the orbit and cheekbones.
4. Partakes in the creation of important sinuses, such as the maxillary sinus, which is located within the body of the maxilla.
Transforming Growth Factor-beta 3 (TGF-β3) is a type of cytokine, specifically a growth factor that belongs to the TGF-β family. It plays crucial roles in regulating various cellular processes such as proliferation, differentiation, apoptosis, and extracellular matrix production.
TGF-β3 has been identified to have significant functions during embryonic development and tissue repair. In particular, it is known to be involved in the regulation of wound healing and scar formation. TGF-β3 can influence the behavior of various cell types, including fibroblasts, epithelial cells, and immune cells.
In some cases, TGF-β3 has been investigated for its potential therapeutic use in reducing fibrosis and promoting tissue regeneration. However, more research is needed to fully understand its mechanisms and potential clinical applications.
Pancreatic neoplasms refer to abnormal growths in the pancreas that can be benign or malignant. The pancreas is a gland located behind the stomach that produces hormones and digestive enzymes. Pancreatic neoplasms can interfere with the normal functioning of the pancreas, leading to various health complications.
Benign pancreatic neoplasms are non-cancerous growths that do not spread to other parts of the body. They are usually removed through surgery to prevent any potential complications, such as blocking the bile duct or causing pain.
Malignant pancreatic neoplasms, also known as pancreatic cancer, are cancerous growths that can invade and destroy surrounding tissues and organs. They can also spread (metastasize) to other parts of the body, such as the liver, lungs, or bones. Pancreatic cancer is often aggressive and difficult to treat, with a poor prognosis.
There are several types of pancreatic neoplasms, including adenocarcinomas, neuroendocrine tumors, solid pseudopapillary neoplasms, and cystic neoplasms. The specific type of neoplasm is determined through various diagnostic tests, such as imaging studies, biopsies, and blood tests. Treatment options depend on the type, stage, and location of the neoplasm, as well as the patient's overall health and preferences.
Neoplasms are abnormal growths of cells or tissues in the body that serve no physiological function. They can be benign (non-cancerous) or malignant (cancerous). Benign neoplasms are typically slow growing and do not spread to other parts of the body, while malignant neoplasms are aggressive, invasive, and can metastasize to distant sites.
Neoplasms occur when there is a dysregulation in the normal process of cell division and differentiation, leading to uncontrolled growth and accumulation of cells. This can result from genetic mutations or other factors such as viral infections, environmental exposures, or hormonal imbalances.
Neoplasms can develop in any organ or tissue of the body and can cause various symptoms depending on their size, location, and type. Treatment options for neoplasms include surgery, radiation therapy, chemotherapy, immunotherapy, and targeted therapy, among others.
The dental arch refers to the curved shape formed by the upper or lower teeth when they come together. The dental arch follows the curve of the jaw and is important for proper bite alignment and overall oral health. The dental arches are typically described as having a U-shaped appearance, with the front teeth forming a narrower section and the back teeth forming a wider section. The shape and size of the dental arch can vary from person to person, and any significant deviations from the typical shape or size may indicate an underlying orthodontic issue that requires treatment.
Neoplasms: Neoplasms refer to abnormal growths of tissue that can be benign (non-cancerous) or malignant (cancerous). They occur when the normal control mechanisms that regulate cell growth and division are disrupted, leading to uncontrolled cell proliferation.
Cystic Neoplasms: Cystic neoplasms are tumors that contain fluid-filled sacs or cysts. These tumors can be benign or malignant and can occur in various organs of the body, including the pancreas, ovary, and liver.
Mucinous Neoplasms: Mucinous neoplasms are a type of cystic neoplasm that is characterized by the production of mucin, a gel-like substance produced by certain types of cells. These tumors can occur in various organs, including the ovary, pancreas, and colon. Mucinous neoplasms can be benign or malignant, and malignant forms are often aggressive and have a poor prognosis.
Serous Neoplasms: Serous neoplasms are another type of cystic neoplasm that is characterized by the production of serous fluid, which is a thin, watery fluid. These tumors commonly occur in the ovary and can be benign or malignant. Malignant serous neoplasms are often aggressive and have a poor prognosis.
In summary, neoplasms refer to abnormal tissue growths that can be benign or malignant. Cystic neoplasms contain fluid-filled sacs and can occur in various organs of the body. Mucinous neoplasms produce a gel-like substance called mucin and can also occur in various organs, while serous neoplasms produce thin, watery fluid and commonly occur in the ovary. Both mucinous and serous neoplasms can be benign or malignant, with malignant forms often being aggressive and having a poor prognosis.
