Steatocystoma Multiplex Localized on the Neck: A Case Report

ABSTRACT

PURPOSE: Steatocystoma multiplex is a hamartomatous malformation of the pilosebaceous duct junction. It is not common and inherited in an autosomal dominant pattern. But numerous non-hereditary cases have been reported. The neck is an unusual site in steatocystoma multiplex. METHODS: A 23-year-old woman was found to have multiple yellowish papules, which had developed on anterior surface of her neck for 10 years. RESULTS: There was no similar lesions on any other parts of the body. Histopathological examination revealed an intricately folded cyst wall consisting of several epithelial layers and flattened sebaceous gland lobules close to the cyst wall, which were typical of steatocystoma multiplex. CONCLUSION: We describe an unusual case of steatocystoma multiplex localized on the neck.
