Primary plasmacytoma of the cervix in a 21-year-old female patient.
Extramedullary (extraosseous) plasmacytomas are localized, plasma cell neoplasms that arise in tissues other than bone and bone marrow, and constitute about 4% of all plasma cell neoplasms. Extramedullary (extraosseous) plasmacytomas rarely affects the female lower genital tract; only 6 cases of primary cervix plasmacytomas have been reported to date. Here we describe the case of an otherwise healthy 21-year-old woman who presented for a routine examination with no symptoms. A Pap smear showed an intense inflammatory process with some atypical cells. This was confirmed by microscopic examination of a biopsy, which revealed a metaplastic process of the cervix with a massive infiltration of plasma cells with mild atypia. The atypical plasma cells showed cytoplasmic lambda immunoglobulin light chain restriction with the absence of kappa light chains, indicative of monoclonality. The patient was extensively screened for systemic disease, including bone marrow biopsy, but the disease was restricted to the cervix.
