Chang, Eundeok; Shim, Sangin

Abstract

Farmer and Helwig coined the term cutaneous ciliated cyst in 1978 to describe specific skin cysts lined with ciliated epithelium a resembling the mucosa of the fallopian tube. Twenty case, of cutaneous ciliated cysts have been published to date. All have been found to affect the lower limb and all patients have been women. The etiology of the cyst is as yet unknown. A 37-year-old woman had a cyst excised from the left buttock. Microscopically, the lining epithelium of the cyst wall was composed of columnar cilited cells similar to those seen in the fallopian tubes. Immunoperoxidase stainings for cytokeratin, epithelial membrane antigen and carcinoembryonic antigen were positive.
