hidrocystoma









































hidrocystoma (also known as cystadenoma, a moll's gland cyst, and a sudoriferous cyst) is an adenoma of the sweat glands.









































hidrocystomas are cysts of sweat ducts, usually on the eyelids. they are not tumours (a similar-sounding lesion called hidroadenoma is a benign tumour).









































there are three types of "sweat" glands: true sweat glands or eccrine glands;









































sebaceous glands, which have an oily secretion around hair follicles; and apocrine glands which have more oily product than eccrine glands and are found on the face, armpit, and groin.

there are two major isoforms of 5α-reductase, srd5a1 (type i) and srd5a2 (type ii), with the latter being the most biologically important isoenzyme. there is also third 5α-reductase: srd5a3. srd5a2 is most highly expressed in the genitals, prostate gland, epididymides, seminal vesicles, genital skin, facial and chest hair follicles, and liver, while lower expression is observed in certain brain areas, non-genital skin/hair follicles, testes, and kidneys. srd5a1 is most highly expressed in non-genital skin/hair follicles, the liver, and certain brain areas, while lower levels are present in the prostate, epididymides, seminal vesicles, genital skin, testes, adrenal glands, and kidneys. in the skin, 5α-reductase is expressed in sebaceous glands, sweat glands, epidermal cells, and hair follicles. both isoenzymes are expressed in scalp hair follicles, although srd5a2 predominates in these cells. the srd5a2 subtype is the almost exclusive isoform expressed in the prostate gland.
