- Eccrine gland carcinoma can arise de novo in a normal sweat gland structure, or it can represent a transformation of a pre-existing benign eccrine neoplasm. (logicalimages.com)
- 8. Axillary apocrine carcinoma associated with apocrine adenoma and apocrine gland hyperplasia. (nih.gov)
- The actual slides of the previous excision were not retrievable, while the pathology report did state that the lesion was "a basal cell carcinoma which in some areas presents gland-like formations, adenoid cystic characteristics and focal areas of keratinization, but it predominantly is an adenoid basal cell carcinoma. (hindawi.com)
- Toker initially described it in 1972 when he reported five cases of trabecular carcinoma of the skin with a putative origin of eccrine sweat gland 4 . (turkjpath.org)

- Sebaceous gland diseases are caused by lack of working in glands, excessive sebum production and inflammation. (esraazman.com)
Diagnosis1
- COVID-19 has caused a delay in diagnosis of malignant neoplasms and consequently, this has resulted in poorer prognoses. (escholarship.org)
