KANOH, T., HATTORI, N., UCHINO, H., FUJITA, A., OHMURA, M. and MAKIMOTO, K. Extramedullary Plasmacytoma of the Parotid Gland: Report of a Case and Review of the Literature. Tohoku J. exp. Med., 1985, 146 (4), 469-478 - A case of primary extramedullary plasmacytoma (PEMP) with local amyloid deposition arising in the left parotid gland of a 78-year-old woman is described. The present case was studied with immunologic techniques with results confirming that the neoplastic cells were of monoclonal nature, producing λ-light chains alone. PEMPs of the salivary glands are rare, with only 8 cases reported in the literature. The salient features of these 9 cases are summarized. Problems connected with the clinical, pathological and therapeutic aspects of PEMP with regard to the rare parotid location are discussed.
