Benign tumors of fatty tissues found in infancy and childhood. It is associated chromosomal aberrations that result in activation of an oncogene on chromosome band 8q12.
Neoplasms composed of fatty tissue or connective tissue made up of fat cells in a meshwork of areolar tissue. The concept does not refer to neoplasms located in adipose tissue.
A benign tumor composed of fat cells (ADIPOCYTES). It can be surrounded by a thin layer of connective tissue (encapsulated), or diffuse without the capsule.
A liposarcoma containing myxomatous tissue. (Dorland, 27th ed)
A malignant tumor derived from primitive or embryonal lipoblastic cells. It may be composed of well-differentiated fat cells or may be dedifferentiated: myxoid (LIPOSARCOMA, MYXOID), round-celled, or pleomorphic, usually in association with a rich network of capillaries. Recurrences are common and dedifferentiated liposarcomas metastasize to the lungs or serosal surfaces. (From Dorland, 27th ed; Stedman, 25th ed)

A rapidly growing soft tissue mass in the axilla of an infant raises the suspicion of a lipoblastoma or a liposarcoma. Excisional/incisional biopsy is vital in confirming the diagnosis and hence avoiding aggressive extirpation. This case report highlights the role of histopathology and immunohistochemistry as the gold standard in differentiating a lipoblastoma from a liposarcoma. In some cases where the histopathology is inconclusive, genetic rearrangement of the PLAG1 (pleomorphic adenoma gene 1) oncogene on chromosome 8q12 helps in confirming the diagnosis of lipoblastoma.  (+info)

Lipoblastoma is a relatively rare, benign tumor that originates from fetal fat tissue. It typically occurs in children under the age of 3, with around 90% of cases diagnosed before the age of 7. These tumors usually grow in the soft tissues of the extremities, trunk, or head and neck region. Lipoblastomas are well-circumscribed, meaning they have a clear border, and they do not typically invade surrounding tissues.

The tumor is composed of immature fat cells called lipoblasts, which are normally found during fetal development but disappear after birth. The presence of these cells in a lipoblastoma suggests that the tumor represents a type of abnormal fat tissue growth.

Lipoblastomas can be classified into two types:
1. Lipoblastoma simplex: This is the more common form, accounting for around 75% of cases. It is a localized tumor that does not spread to other parts of the body.
2. Lipoblastomatosis: This type is less common and tends to be more invasive. It consists of multiple, interconnected lipoblastomas that can grow and infiltrate surrounding tissues.

Treatment for lipoblastoma typically involves surgical removal of the tumor. Recurrence after surgery is possible but relatively uncommon, especially if wide margins are achieved during resection. Malignant transformation of a lipoblastoma into a liposarcoma, a type of cancerous fat tissue tumor, is extremely rare.

Neoplasms in adipose tissue refer to abnormal and excessive growths of cells that form tumors within the fatty connective tissue. These neoplasms can be benign or malignant (cancerous). Benign neoplasms, such as lipomas, are slow-growing and typically do not spread to other parts of the body. Malignant neoplasms, on the other hand, are cancerous and can invade surrounding tissues and spread to distant sites in the body (metastasis). An example of a malignant neoplasm in adipose tissue is liposarcoma. It's important to note that while some neoplasms may not cause any symptoms, others can cause pain, swelling or other uncomfortable sensations, and therefore should be evaluated by a medical professional for proper diagnosis and treatment.

A lipoma is a common, benign (non-cancerous) soft tissue growth. It is composed of adipose or fatty tissue and typically found just beneath the skin, but they can also occur deeper within the body. Lipomas are usually round, moveable, and painless, although they may cause discomfort if they grow large enough to put pressure on nearby nerves or if they're located in a sensitive area. They generally grow slowly over time. Surgical removal is an option if the lipoma becomes bothersome or grows significantly in size. It's important to note that while lipomas are typically harmless, any new lumps or bumps should be evaluated by a healthcare professional to confirm the diagnosis and rule out other more serious conditions.

Liposarcoma, myxoid type, is a specific subtype of liposarcoma, which is a malignant (cancerous) tumor that develops from fat cells. Myxoid liposarcoma is characterized by the presence of a gel-like substance in the tumor tissue. It usually occurs in deep soft tissues, such as muscles, tendons, and ligaments, and can be found in various parts of the body, but it most commonly affects the thigh.

Myxoid liposarcoma tends to grow slowly and has a better prognosis compared to other subtypes of liposarcoma. However, it can still metastasize (spread) to other parts of the body, such as the lungs, bones, and lymph nodes. Treatment typically involves surgical removal of the tumor, with radiation therapy and/or chemotherapy used in some cases to help reduce the risk of recurrence or spread.

It's important to note that while I strive to provide accurate information, my responses should not be used as a substitute for professional medical advice, diagnosis, or treatment.

Liposarcoma is a type of soft tissue sarcoma, which is a cancer that develops in the soft tissues of the body, such as fat, muscle, nerves, blood vessels, and fibrous tissues. Specifically, liposarcoma arises from fat cells (adipocytes) or their precursors.

There are several subtypes of liposarcoma, which differ in their appearance under the microscope, genetic features, and clinical behavior. These include well-differentiated, dedifferentiated, myxoid, round cell, and pleomorphic liposarcomas. The most common sites for liposarcoma are the thigh, retroperitoneum (the area behind the abdominal cavity), and the buttock.

Liposarcomas can grow slowly or rapidly, and they may spread to other parts of the body (metastasize) through the bloodstream or lymphatic system. Treatment typically involves surgical removal of the tumor, often followed by radiation therapy and/or chemotherapy. The prognosis for liposarcoma depends on several factors, including the type and grade of the tumor, its size and location, and whether it has spread to other parts of the body.
