Cutaneous Adnexal Cysts Revisited: What We Know and What We Think We Know

June 2018 in “ Dermatopathology ”

Gürkan Kaya, Jean‐Hilaire Saurat

TLDR A new classification system for skin cysts was proposed to improve diagnosis.

The document proposed a novel classification of cutaneous adnexal cysts based on their origin in the folliculosebaceous unit and sweat glands. It identified specific characteristics of the cystic structures' epithelial linings to determine their origins: epidermal cysts from the infundibulum, tricholemmal cysts from the isthmus, and steatocystoma, dermoid cyst, and folliculosebaceous hamartoma from the sebaceous duct. Hidrocystoma was linked to sweat glands, and hair matrix cysts to the hair matrix. The classification aimed to simplify the understanding of these cysts' origins and improve diagnostic accuracy.

community Androgenetic alopecia is a skin disease: DHT-mediated skin disorders

in Research/Science 65 upvotes 1 year ago

Dihydrotestosterone (DHT) impacts various skin conditions, including Androgenetic alopecia and seborrheic dermatitis, by causing overactivity in sebaceous glands. Topical medications Tacrolimus and Clobetasol can reduce these inflammatory conditions, and treatments like RU58841, Minoxidil, and Finasteride may also be beneficial.

community Why is everyone not directly advised Dutasteride?

in Finasteride/Dutasteride 165 upvotes 1 month ago

Dutasteride is less commonly prescribed for hair loss because it is not FDA-approved for this purpose, unlike finasteride, which is more accessible and preferred due to fewer side effects. Dutasteride may be more effective in reducing DHT but has a longer half-life and potentially more significant side effects.
