Cutaneous and Systemic Plasmacytosis in a Case of Rib Pain and Anemia - Abstract
A 67-year-old woman was admitted to our department presenting with rash, rib pain and anemia. The patient had had a rash for 20 years, and was previously diagnosed with multiple myeloma at her local hospital. The patient doubted both the diagnosis of multiple myeloma and the effectiveness of the treatment. We discovered that this patient had in fact been misdiagnosed for multiple myeloma, and then diagnosed her as having cutaneous and systemic plasmacytosis (CSP) by skin biopsies.
