Platelet rich plasma: Good for whatever ails you?
Okay, okay, I admit it. The first time I ever heard of injecting autologous platelet rich plasma (PRP) for pattern alopecia, my suspicion was that it was being sold by the proverbial snake-oil salesman. I did my utmost to ignore it, but increasingly its use is being reported, and patients

Of every possible solution for elastosis perforans serpiginosa, fractional carbon dioxide laser may be the best
My initial attraction to dermatology, which still offers great appeal, is the challenge and joy of differential diagnosis and clinical-pathologic correlation.

The heartrending aspects of incontinentia pigmenti

Subungual tumors make me nervous. I realize that most are benign (subungual exostosis, osteochondroma, onycholemmal cyst, glomus tumor, pyogenic granuloma, wart, fibroma, acral fibromyxoma), however subungual malignant lesions (squamous cell carcinoma, keratoacanthoma, melanoma) occur.

Erosive pustular dermatosis of the scalp must no longer be dermatology’s secret

Something from nothing: The role of random skin biopsies
As dermatologists we hone our skills on visual diagnostic clues, allowing us to choose optimal lesions to biopsy for clinical-pathologic correlation. The concept of random skin biopsies (RSB) of normal skin searching for pathology may seem foreign (or heretical); however, in the right circumstances, it may yield vital diagnostic information.

Ask any child when how long it is until their next birthday and they can usually give you a precise answer. If I’m treating a child with periorificial dermatitis (POD, also granulomatous POD or perioral dermatitis), I can’t wait until they turn 8, so I can prescribe doxycycline.

Mucho de Mucha-Habermann

My patients with eosinophilic fasciitis (EF, Shulman syndrome) have been fortunate.
