Two patients are described, each of whom developed multiple eruptive lesions on sun-exposed areas within days after starting benoxaprofen therapy. The lesions were 2- to 5-mm papules suggestive of syringomas, and microscopically showed squamous metaplasia of eccrine ducts and focal necrosis of eccrine keratinocytes as well as prominent eccrine hyperplasia. In both cases, the lesions resolved completely after benoxaprofen therapy was discontinued. A theoretical basis for these findings is discussed.
Hand-Schüller-Christian disease is a disease primarily affecting children, occasionally young adults, and rarely older adults. Very few cases have been reported in individuals past their fifth decade. A review of the English language literature indicates that the onset of Hand-Schüller-Christian disease occurs after the fifth decade in less than 4% of reported cases. A 75-year-old woman's symptoms of Hand-Schüller-Christian disease began in her 76th year, and her cutaneous symptoms were controlled with a topically applied nitrogen mustard.
