Introduction And Importance: Solitary extramedullary plasmacytoma (SEP) is a rare plasma cell neoplasm, constituting around 3 % of plasma cell malignancies. SEP typically presents as a single tumor, either in bone or soft tissue, without systemic disease, and is often misdiagnosed due to its nonspecific symptoms. Diagnosis requires biopsy and extensive imaging studies to exclude multiple myeloma and other malignancies.

A 72-year-old male patient presented fatigue, anemia, elevated total protein, IgG, IgG4, IL-6, and vascular endothelial growth factor (VEGF) levels. Initial diagnostics suspected multiple myeloma. A plane computed tomography (CT) scan showed pneumonia and the enlargement of generalized lymph nodes.

Multiple myeloma (MM) remains incurable despite novel therapeutics. A major contributor to the development of relapsed/refractory and resistant MM is extraosseous extramedullary disease (EMD), whose molecular biology is still not fully understood. We analyzed 528 MM patients who presented to our institution between 2014 and 2021 and who had undergone molecular testing.

Rationale: Extramedullary plasmacytoma is an extremely rare malignant clonal plasmacytoma, which can occur in any tissue or organ of the body other than bone marrow hematopoietic tissue. Lesions mostly occur in the head and neck or upper respiratory tract, and rarely in the lower respiratory tract. Primary plasmacytoma of the lung, also known as primary pulmonary plasmacytoma (PPP), is rarer and is mainly diagnosed on the basis of the histopathology of biopsy tissue.

Multiple myeloma (MM) is the second most prevalent hematologic malignancy, particularly affecting the elderly. The disease often begins with a premalignant phase known as monoclonal gammopathy of undetermined significance (MGUS), solitary plasmacytoma (SP) and smoldering multiple myeloma (SMM). Multiple imaging modalities are employed throughout the disease continuum to assess bone lesions, prevent complications, detect intra- and extramedullary disease, and evaluate the risk of neurological complications.
