Atypical low back pain by solitary plasmacytoma bone coexisiting with psoas abscess: 2 different entities in a same location. The first case report [Lumbalgia atípica por plasmocitoma óseo solitario coexistente con absceso de psoas: 2 entidades distintas en una misma localización. Reporte del primer caso]

Abstract

The solitary bone plasmacytoma (SBP) is the least common of the plasma cell neoplasms, most often appears in the fifth decade of life, and their symptoms are related to chronic bone pain. We present the first case report in the literature of a rare coexistence of an infiltrating spinal injury by a solitary plasmacytoma with an abscess in the psoas muscle; we characterize this coincidence that confuses the diagnosis of SBP. 1665-9201
