Solitary plasmacytoma of the chest wall. A case report.

Solitary plasmacytic lymphomas are rarely described in the lung. Generally, localized neoplasms develop into mediastinal or pulmonary lymphnodes and are hard to differentiate from other lung neoplasms. An involvement of the chest wall in multiple myeloma is not rare, and is generally associated with other skeletal localizations. A secreting solitary plasmacytoma of the ribs is rather uncommon: a personal review of the literature has showed, in the last ten years, only two cases of these tumors, secreting IgG lambda light chains. In this study we report a case of solitary plasmacytoma of the chest wall, associated with an IgG kappa monoclonal gammapathy.
