耳下腺皮脂リンパ腺腫例 A Case Report of Sebaceous Lymphadenoma
A 75-year-old woman presented with a several month history of an elliptical and painless tumor in the left side of the parotid gland. Based on MRI and FNABC we made an initial diagnosis of adenolymphoma and removed the mass surgically. Histologic examination revealed sebaceous lymphadenoma. Sebaceous lymphadenoma are rare tumors and to date only 34 cases have been reported worldwide, as reviewed Douglas et al. Sebaceous differentiation in the parotid gland is an expected normal finding in humans. There has been one previous report in which the relation between salivary gland inclusions of the lymph node in the gland and sebaceous differentiation were discussed. We compared this case to other cases reported in the literature and dicussed this disease in regard to genesis and pathology.
