Case report of peritoneal carcinomatosis of plasma cell origin in a patient with newly diagnosed HIV: A terminal event.

BACKGROUND: B-cell tumors and plasma cell malignancies have been identified in persons living with the human immunodeficiency virus (PLHIV). The literature review has revealed numerous reports of solitary plasmacytomas with metastasis in PLHIV. CASE REPORT: A young patient with no prior medical or surgical history presented with tumor lysis syndrome secondary to metastatic plasma cell Epstein-Baer virus (EBV) related malignancy with peritoneal carcinomatosis. The history and clinical picture promptly led to the diagnosis of HIV. The subsequent hospital course was dismal, and lifespan was cut short by multi-organ failure.
CONCLUSION: This case is being reported to highlight the suspicion of HIV in patients presenting acutely with aggressive plasma cell malignancies.
