A 46-year-old man presented with persistent right otalgia and hearing loss. Exam was significant for a mildly tender retromandibular mass with intact nonerythematous overlying skin. Computerized tomography with intravenous contrast of the neck revealed 2 relatively well circumscribed masses in the right parotid gland. Although 1 lesion was suspected to be a necrotic lymph node, histologic analysis after superficial parotidectomy demonstrated 2 unique salivary gland tumors. Diagnoses of both sebaceous lymphadenoma and membranous basal cell adenoma were rendered. The occurrence of unique, synchronous, ipsilateral salivary gland tumors is distinctly unusual and this combination of parotid gland neoplasms has not previously been documented. In this report, we present the case with its management, followed by a discussion of the histopathologic nature of each tumor including the possible overlap between these two entities.
