keratosis pilaris haemosiderin deposition scurvy vitamin C deficiency purpuric rash vasculitis histopathology

TLDR A man's skin condition and poor diet led to a scurvy diagnosis.

A 50-year-old man presented with a purpuric rash initially suspected to be vasculitis. Histological examination of skin biopsies revealed keratosis pilaris with perifollicular haemosiderin deposition, suggesting scurvy. The patient had a history of poor diet and alcohol consumption, with low serum vitamin C levels (9 μmol/L). The diagnosis of scurvy was confirmed, leading to appropriate nutritional intervention. This case highlights the importance of considering scurvy in differential diagnoses and the critical role of histopathology in identifying misleading clinical presentations.

community here is why isotretinoin might cause hair loss and maybe why dupa happens.

in Research/Science 7 upvotes 1 year ago

Isotretinoin may cause hair loss by increasing DHT through a precursor androgen, DHEAS. Treatments like topical antiandrogens (RU58841, pyrilutamide) and drugs increasing PPAR-y expression (pioglitazone) might prevent this hair loss.
