Three patients with extramedullary plasmacytoma of the lung are described, one of whom also had cervical lymph node metastasis, with the production of an M-protein. The production of M-protein normalized after successful treatment of the localized disease. In all three patients, the disease was loca

โฆ Synopsis
Primary extramedullary plasmacytoma (PEMP) is a tumor of atypical neoplastic cells that arise outside the bone marrow in patients without clinical evidence of existing multiple myeloma. These rare tumors, which can occur in virtually any part of the body, have shown a clear predilection for the head and neck.
Yet despite the fact that nearly 80% of these tumors can be found in the upper respiratory tract or oral cavity, their involvement in the parotid is singularly rare. The clinical behavior of this tumor is not yet well-defined, and local recurrence, distant rnetastasis, and transformation to multiple myeloma have all been reported. Since the first case of parotid PEMP was reported in 1965, 8 additional cases have been noted in the literature. This is the 9th case of PEMP of the parotid to be described.

Extramedullary plasmacytoma of the parotid gland is an extremely rare lesion of which there have been only four other reported cases. The importance of these lesions rests in the possibility of their being a harbinger of multiple myeloma or their subsequent transformation to multiple myeloma. Becaus
Solitary extramedullary plasmacytoma is an uncommon neoplasm and occurs most frequently in the upper respiratory tract.

A retrospective analysis of 18 cases of extramedulary plasmacytoma (EMP) was done to characterize the type of immunoglobulin being synthesized by the neoplastic cells. The immunoperoxidase stain can be performed on previously fixed tissue and offers a means of predicting the likelihood of progressio
