An Unusual Case of Pancytopenia.

Multiple myeloma is a rare hematological disorder that causes overproduction of plasma cells within the bone marrow, leading to suppressed hematopoiesis, renal insufficiency, bony lesions, and recurrent infections. Patients with multiple myeloma commonly present with anemia. Although rare, neutropenia and thrombocytopenia can also develop in these patients, leading to pancytopenia, as seen in our case. Therefore, multiple myeloma should be kept as one of the differentials in elderly patients who present with pancytopenia for early screening and diagnosis of the disease.
