Dermatol Sinica 22 : 270-271, 2004

A 51-year-old married woman presented with a 6-month history of an asymptomatic eruption on the trunk. On examination, there were numerous pearly semi-translucent erythematous papules, varying in diameter from 2 to 4 mm (Fig. 1). The skin eruptions appeared to be located with a follicular-centric distribution. There were no central umbilication although occasional lesions had a hair growing through the center. According to the patient’s statement, the lesions suddenly appeared on the anterior chest and spreaded rapidly over the whole trunk. She had been treated toward bacterial folliculitis but in vain at local clinics. The patient had a regular sexual partner. She did not have atopic dermatitis. However, she has a noteworthy habit of taking saunas for 10 years and taking spas for one year. Serological examination of HIV was performed which showed a negative result. Peripheral blood T-cell subsets were normal. A skin biopsy was taken from a papule on the anterior abdomen (Fig. 2 and Fig. 3). After being treated with three courses of cryotherapy with liquid nitrogen, the lesions cleared without scarring or recurrence.
