Plasmacytoma of the Cervix Possibly Caused by Neglected Pessary: A Case Report and Literature Review

Background & Objective: Plasmacytoma is a rare plasma cell dyscrasia marked by localized monoclonal plasma cell proliferation, distinct from multiple myeloma by its lack of systemic symptoms. Extramedullary plasmacytoma (EMP), the rarest form, typically occurs in the upper respiratory tract. Cervical involvement is rare. Chronic inflammation may play a role in the development of cervical plasmacytoma, though this remains unproven for cervical cases.Case Presentation: We present a unique case of a ۷۴-year-old woman who presented with vaginal bleeding linked to a neglected pessary inserted ۱۵ years earlier. Upon examination, we discovered overgrown tissue with active bleeding. The biopsy revealed a monomorphic plasma cell infiltration, and immunohistochemistry confirmed CD۱۳۸-positive, BCL۲-negative cervical plasmacytoma, a rare occurrence in the cervix.Conclusion: This case highlights the importance of considering cervical EMP in atypical cytology and suggests a possible link to chronic pessary-induced inflammation. Early diagnosis through histopathology and immunohistochemistry is essential.
