Abstract:
A yellow cyst of the caruncle in a 68-year-old man displayed the characteristic sebaceous glands and sebocytes of steatocystoma within the cyst wall, with a unique configuration of multiple branching compartments. The cyst lining was of trichilemmal character, lacking a keratohyalin granular layer, and replicated the immunohistochemical characteristics of a previously reported caruncular steatocystoma with the exception of a positive trichilemmal marker, calretinin, in the present case. Four previous cases of caruncular steatocystoma have been described, only one of which incorporated immunohistochemical analysis. Steatocystoma develops from a sebaceous gland duct, which displayed in this case multiple chambers subdividing what is usually a single round lumen.
