Aseptic Necrosis of Warts Instead of Lymphangitis

The document discusses various dermatological conditions and their potential causes. It mentions that the stippled skin condition known as erythrosis interfollicularis colli, which is characterized by small, yellow follicular papules, has been associated with both sun exposure and corticosteroid medication. Borensztein and Kohan's study divided patients into three groups based on sun exposure and corticosteroid treatment, finding that 67% of patients with prolonged corticosteroid use without sun exposure and 69% with sun exposure but minimal corticosteroid use exhibited cutis punctata linearis colli, while only 28% of those without either condition did. The document also addresses a letter by Dr. Harry L. Roth, who argues against the specific association of lymphangitis with cantharidin treatment for warts, suggesting that aseptic necrosis of warts can occur with various treatments that cause dermal-epidermal separation. Lastly, it includes a letter by Dr. Daniel J. Trozak regarding hair loss after therapy with chorionic gonadotropin, noting that hair loss occurred in a small percentage of patients approximately four to six weeks after discontinuing a regimen of chorionic gonadotropin injections and a low-calorie diet, suggesting a pharmacological effect of the hormone as a potential cause.
