title: Multiple cystic disease: K17 dysfunction?
abstract: Our patient is a 29-year-old woman without any previous disease who presented with different kinds of lesions on her face, neck, and chest. She first noticed the lesions 10 years ago and, since that time, they have become more numerous. She has no affected relatives. On physical examination, she had multiple cystic lesions on her neck, chest, and vulva, which were between 0.3 cm and 1 cm and skin-colored or yellowish (Figure 1). She presented with small, white papules on her face measuring approximately 0.2 cm, localized on her forehead and cheeks. Some of these papules had a blueish appearance (Figure 2). She also presented clinically typical eruptive syringomas on her upper and lower eyelids and neck and multiple facial milia. Finally, a sacrococcygeal pilonidal cyst was diagnosed and surgically removed. Her nails and teeth were clinically normal. Biopsies of each kind of lesion were performed, with the following results: (1) neck cystic lesion: steatocystoma; (2) small, white facial papule: eccrine hidrocystoma; (3) blueish facial papule: apocrine hidrocystoma; and (4) small neck papule: syringoma (Figure 3). With these findings, our diagnosis was steatocystoma multiplex with multiple eccrine and apocrine hidrocystomas, eruptive syringomas, and sacrococcygeal pilonidal cyst.
