TLDR Most cutaneous adnexal tumors examined were benign and resembled common skin tumors.

The systematic review "Dermoscopy of cutaneous adnexal tumours" analyzed 206 articles, covering 372 adnexal tumours (ATs) in 365 patients. The majority of ATs were apocrine-eccrine (58.3%, n=217), followed by follicular ATs (23.7%, n=88) and sebaceous ATs (18.0%, n=67). Histopathological analysis showed 82% benign (n=305) and 18.0% malignant (n=67). The study found that ATs can mimic common skin tumours like basal cell carcinoma, squamous cell carcinoma, melanocytic lesions and benign cutaneous lesions. The review also detailed the dermoscopic features of various types of skin tumors, including their color, structure, and vessel appearance. The study's limitation was the selective inclusion of lesions with dermoscopic pictures available and reliance on the diagnosis provided by the authors of the included articles.

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.
