Sebaceous adenoma of the parotid gland.

چکیده
Tumors of the salivary glands constitute an important field of oral and maxillofacial pathology. The majority of salivary gland neoplasms are benign, with malignant salivary tumors accounting for 15 to 32 percent. The most common site for salivary gland tumors is the parotid gland, accounting up to 80 percent of all cases. This article reports the pathologic picture in a case of sebaceous adenoma of the parotid gland. The tumor was composed of epithelial cells lining ducts and closely associated with broad areas of sebaceous differentiation. The growth pattern was predominantly cystic, with cavities filled with sebaceous material. Areas of oncocytic metaplasia were also seen. The presence of sebaceous glands in salivary neoplasms is frequent, however, and in spite of this, salivary neoplasms constituted partially or entirely of these cells are rarely observed. To the surgeon and pathologist, the major problem in dealing with sebaceous adenoma is the recognition of this rare entity, avoiding confusing with other more aggressive neoplasms. The treatment involves surgical excision. The addition of the current case to the previously published data brings the total number of parotid sebaceous adenoma to seven.

CT of sebaceous adenoma of the parotid gland.
We report a large sebaceous adenoma of the parotid gland. CT showed soft-tissue mass in the lateral portion of the adenoma corresponding to the histologic finding of proliferation of sebaceous glands and fibrous stromal tissue. There were numerous fatty cysts (-65Hu). Some of the cystic component ruptured, and CT demonstrated leaking of fatty material into the parapharyngeal space.
