title: Sclerosing sweat duct carcinoma of the nose with multiple cervical lymph node metastasis.
abstract: Sclerosing sweat duct carcinoma (SSDC) in the nose, a rare occurrence with no specific symptoms, is frequently confused with rhinophyma or other inflammatory disease. In this report, we describe a 64-year-old woman who presented with a mass on her nasal dorsum for 1 year. Initially, the tumor had been misdiagnosed as a rhinophyma and followed-up for 1 year. She was referred due to a persistent nasal and neck mass. Deep incisional biopsy was performed to produce sufficient tissue and the histopathologic results showed SSDC. We performed wide local excision and reconstruction using radial forearm musculocutaneous free flaps with a costal cartilage framework followed by bilateral neck dissection. SSDC is seldom recognized and is frequently clinically confused with benign syringoma prior to pathologic diagnosis. Wide and deep incisional biopsy is necessary for the correct diagnosis and successful treatment of SSDC.
