Two cases of eccrine hidrocystoma / 대한피부과학회지

ABSTRACT

We report two cases of eccrine hidrocystoma, one in a 13-year-old-female and the other a 56-year-old male. In the first case, rnultiple pale blue, translucent, discrete yellow papules of one years duration were noted on the nose tip of the nose. The second case presented with a tiny asympt,omatic papule superimposed on a slightly erythematous 2cm-sized, round patch on the forehead for 2 months. In both cases, the histopathology demonstrated a cystic space filed with eosinophilic amorphous material. The cyst wall was lined by two layers of cuboidal pithelial cells with eosinophilic cytoplasm. PAS staining showed PAS-positive materials in he cytoplasm of cyst wall epithelium, lumen, and eccrine gland cells. Topical application of 10% atropine sulfate and surgical excision were performed in the each cases with improvernent.
