REPORT OF A CASE
A 33-year-old man in otherwise good health presented with a pruritic rash on his trunk and face of 3 months' duration. The lesions developed rapidly over 2 weeks. Subsequently, no lesions resolved, nor did new lesions appear. Various over-the-counter lotions, as well as topical and oral corticosteroids, topical antifungal agents, and topical retinoids failed to affect the appearance of the eruption or the associated intense pruritus.Physical examination disclosed numerous slightly oval, flesh-colored to slightly hyperpigmented, flattopped papules concentrated on the chest, but also scattered over the face and back (Figs 1 and 2). A punch biopsy specimen of a papule is shown in Figs 3 and 4.What is your diagnosis?
Eruptive syringomas (eruptive hidradenomas of Jacquet and Darier).
Syringomas usually present as single or multiple, soft, flesh-colored papules in the periorbital region. Less common sites of predilection include the axilla, umbilicus, and pubic region. There are also several reports
