Distinction of benign sebaceous proliferations from sebaceous carcinomas by immunohistochemistry.
Sebaceous lesions, including sebaceous hyperplasia, sebaceomas, and sebaceous adenomas and carcinomas, are histologically distinctive adnexal proliferations with a spectrum of biological behavior ranging from benign to frankly malignant. The histologic distinction between sebaceous adenomas and carcinomas may be challenging, especially in cases showing atypical features and in small or partial ...
متن کاملCanine Skin Tumours with Adnexal Differentiation: Histopathology and Immunohistochemistry
Thirty nine canine adnexal tumours were histologically and immunohistochemically analysed. They were classified as trichoblastomas, trichoepitheliomas, sebaceous adenomas and epitheliomas, hepatoid gland adenomas and epitheliomas, and aporcine adenocarcinomas. Moreover, hepatoid gland angioadenoma and angioepithelioma were recognised. Studies of follicular tumours revealed coexpression of cytok...
متن کاملQuantitative Cytomorphology as an Additional Tool for Differentiation between Canine Cutaneous Sebaceous Adenomas and Sebaceous Carcinomas: a Preliminary Report
Eight canine cutaneous sebaceous adenomas and eight canine cutaneous sebaceous carcinomas were analyzed by computer-assisted nuclear morphometry in Hemacolor stained cytological specimens. In each case, the nuclei of at least 100 neoplastic cells were measured, and the mean nuclear area (MNA), mean nuclear perimeter (MNP), minimum nuclear diameter (D min), maximum nuclear diameter (D max) and m...

متن کاملSebaceous adenoma of the submandibular gland: a case report.
Sebaceous adenoma of the salivary gland is a rare tumor comprising 0.1% of all salivary gland neoplasms and less than 0.5% of salivary adenomas. Histologically, sebaceous adenomas are benign neoplasms consisting of sebaceous cells arranged in nests forming acinar and duct-like structures. Oncocytic metaplasia may also occur in some areas. We describe a case of sebaceous adenoma in the submandib...
