Purpose: To describe an adolescent with solitary plasmocytoma of bone and compare the pathologic and radiographic findings with osteomyelitis.
Patient And Methods: A 17-year-old girl had a 3-year history of swelling of the right tibia, local pain, and hyperemia.
Results: Initial biopsy was interpreted as osteomyelitis. The lesion was rebiopsied 3 years later and showed a plasma cell neoplasm. A review of the first biopsy confirmed a similar histologic picture.
Conclusion: Although solitary plasmocytoma of bone is a rare neoplasm in adolescence, it must be considered in the differential diagnosis of chronic osteomyelitis.

This case highlights the importance of thoroughly investigating incidental findings, particularly in patients with unexplained symptoms. Solitary plasmacytoma, though rare and accounting for 4-5% of plasma cell dyscrasias, can occur outside the spine and may present without systemic symptoms. Early diagnosis through imaging and biopsy is crucial for appropriate management, as these lesions can be effectively treated if identified early.

Primary solitary extramedullary plasmacytoma is a malignant neoplasm characterized by the monoclonal proliferation of plasma cells outside the bone marrow. The tumor rarely occurs in the sinonasal tract, accounting for about 4% of all non-epithelial sinonasal tumors. Herein, the authors describe a rare case of sinonasal extramedullary plasmacytoma in a 33-year-old man who presented with a 3-month history of progressively increasing nasal mass, causing obstruction.

Introduction: Immunoglobulin D (IgD) myeloma is a rare subtype often described as aggressive with advanced disease at diagnosis. Primary renal involvement is seen in scarce cases.
Observation: This case features a 55-year-old man with IgD lambda myeloma presenting severe renal failure at diagnosis.

Abdominal multiple extramedullary plasmacytoma (EMP) is a rare disease. CD38-negative relapsed/refractory EMP after treatment with daratumumab has never been reported. In 2020, a patient with jaundice was diagnosed with plasmacytoma in another hospital, which progressed one year after receiving multiline therapy.

Extramedullary plasmacytomas (EMP) are uncommon solitary tumors composed of neoplastic plasma cells occurring outside the bone. These lesions are of clinical significance due to their potential progression to multiple myeloma (MM), a more systemic and serious plasma cell malignancy. Although EMPs primarily arise in the head and neck region, cases involving the oral cavity are particularly rare.
