Nodular hidradenoma, also known as clear cell hidradenoma or acrospiroma is a benign rare skin tumour arising from the eccrine type of sweat glands.
It has several synonyms including clear cell hidradenoma, eccrine acrospiroma and solid cystic hidradenoma.
Other cystic lesions included in the differential diagnosis of eccrine hidrocystomas are follicular cysts, epidermal inclusion cysts, hemangioma, lymphangioma, apocrine hidrocystoma and eccrine acrospiroma.
INTRODUCTION: Acrospiroma is an uncommon adnexal tumor arising from eccrine glands and commonly seen on the face and the upper extremities.
Clear cell hidradenoma, also known as eccrine acrospiroma, usually presents as a solid and cystic nodule with no site predilection, although it is only rarely reported to occur on the vulva.
A rare case of atypical eccrine acrospiroma of the scalp and a literature review.
We describe a case of malignant eccrine acrospiroma in an 80-year-old man, and we review the literature on this tumor, with emphasis on the differential diagnosis.
DISCUSSION: Nodular hidradenoma is also known as clear cell myoepithelioma, clear cell hidradenoma, eccrine sweat gland adenoma of clear cell type, solid cystic hidradenoma and eccrine acrospiroma.
Such an approach, however, poses several problems; for example, (1) some carcinomas have no benign counterpart and do not fit the scheme (eg, ductal carcinoma, adenoid cystic carcinoma, and mucinous carcinoma); (2) poorly differentiated carcinomas can be diagnosed only when a contiguous adenoma is found histologically; (3) histologic classification can be very complicated because adenomas are numerous and their classification is complex; and (4) terminology includes unusual and difficult terms, deriving from the terminology used for adenomas (eg, malignant acrospiroma, porocarcinoma, hidradenocarcinoma, malignant cylindroma, malignant spiradenoma, and syringo-cystadenocarcinoma).
Hidradenoma may have variable histomorphological patterns reflected by the various terms used to describe this entity: nodular hidradenoma, eccrine acrospiroma, solid-cystic hidradenoma, clear cell hidradenoma, and clear cell acrospiroma.
DISCUSSION: Nodular hidradenoma (NH) is also known as eccrine acrospiroma, clear cell hidradenoma and solid cystic hidradenoma.
INTRODUCTION: Clear cell hydradenoma is known by various other names such as nodular hidradenoma, eccrine acrospiroma, and solid-cystic hidradenoma.
