Sebaceous lymphadenoma of salivary gland: a case report and a review of the literature.
The unusual case is described of a benign parotid gland neoplasm with intermingled sebaceous and lymphoid tissue, synchronous to breast cancer. In the past, the patient had undergone a simple surgical procedure for a cystic parotid gland lesion in that same gland. Secondary neoplasms have only occasionally been reported, since there are few cases for corroborating the strong correlation between salivary neoplasms and other carcinomas as in Muir-Torre syndrome; the previous cystic lesion showed the origin of the neoplasm from a sebaceous inclusion in the lymph node as a postulate of Warthin tumour.
