Multicentric dermal-type cylindromas of the parotid glands in a patient with florid turban tumor.

Abstract

Dermal-type cylindromas of parotid glands in a patient with turban tumor, and various adnexal tumors, represent a rare diathesis, apparently not reported previously. A Caucasian man, born in 1916, had a scalpectomy for turban tumor in 1957. In 1957, 1960, and 1974, dermal type cylindromas were excised from portions of both parotid glands, developing from intercalated and striated ducts; they were considered benign, based on long term followup. Adrexal tumors included multiple dermal cylindromas, trichoepitheliomas, eccrine spiradenomas, and Bowen's disease, and occurred on almost all skin surfaces. In November, 1976, a portion of a right parotidectomy included a 3.5 X 3-cm malignant tumor having the characteristics of an invasive poorly differentiated spindle cell epidermoid carcinoma, which showed no evidence of originating from a malignant basal cell tumor. Several encapsulated and developing benign basal cell tumors were included in the specimen. Dermal-type cyclindromas of the parotid gland are considered to be a variant of basal cell ademona, or monomorphic adenoma, basal cell type, since they consist of similar cell components, although of somewhat different arrangement and with prominent focal deposition of hyaline. Dermal-type cylindromas should be excised conservatively as they appear. They must be differentiated from adenoid cystic carcinoma, which is an infiltrating neoplasm and requires a radical surgical approach.
