Tubular Apocrine Adenoma in Association with an Apocrine Hidrocystoma

Apocrine hidrocystoma with mucinous metaplasia.

Hidrocystoma is a rare cystic lesion arising from the sweat glands, and is classified into apocrine and eccrine variants, with the majority being of apocrine nature [1]. It is usually found in the head and neck region, and commonly affects the periorbital area [1, 2]. Apocrine hidrocystoma is characterized histopathologically by the presence of a unilocular or multilocular cyst situated in the ...

Apocrine Hidrocystoma of the Cheek

detected in several cases [4]. In our case, immunohis-tochemical staining for vimentin was not performed. Positivity for vimentin implies that the tumor cells are of fibroblastic lineage. However, we were able to determine that with the satellite to spindle shape of cells. Histopathologically, the tumors appear well-mar-ginated under low-power microscopic examination. The tumor cells are relati...

Syringocystadenoma papilliferum combined with a tubular apocrine adenoma*

Syringocystadenoma papilliferum and tubular apocrine adenoma are rare benign sweat gland tumors. Syringocystadenoma papilliferum occurs alone or in association with other tumors. Although it is rare, the association of tubular apocrine adenoma with syringocystadenoma papilliferum developing in a sebaceous nevus on the scalp is well documented. However, the co-existence of these two tumors witho...

Axillary apocrine carcinoma associated with apocrine adenoma and apocrine gland hyperplasia.

Apocrine carcinomas represent a rare group of tumors with a potential for destructive local invasion, regional and distant metastases, and are equally common in both sexes. A case of a 79-year-old woman with axillary apocrine carcinoma associated with apocrine adenoma and apocrine gland hyperplasia is presented. To our knowledge, this is the first case diagnosed in a Caucasian and also the firs...
