A Case of Clear Cell Syringoma in an Adult Male / 대한피부과학회지

ABSTRACT

Clear cell syringoma has two distinct features from typical syringomas histological predominance of clear cells and a correlation with diabetes mellitus. Otherwise it is similar to ordinary syringomas in age, sex, site, and clinical manifestations. We here report a 49-year-old male with clear cell syringoma accompanied with diabetes mellitus. Histological examination revealed numerous, variable-sized, well-defined tumor nests composed largely of clear cells that stained positive with PAS (Periodic Acid Schiff) before diastase digestion and negative after diastase digestion.
