[Primary bronchial plasmacytoma: computed tomography findings].

Extramedullary plasmacytomas are malignant neoplasms of the plasmatic cells of the soft tissues. Primary pulmonary plasmacytoma is the rarest type of extramedullary plasmacytoma. The radiologic findings are unspecific and the diagnosis is histologic. Chest CT is useful for confirming its location and planning surgery. We present a case of primary endobronchial plasmacytoma in an adult diagnosed at histology. We describe the findings at plain-film chest X-ray and at CT, and we analyze the usefulness of 3D reconstructions for planning surgery.
