A patient is described with infiltrating ductal carcinoma of the breast presenting with left breast mass and polymyalgia rheumatica (PMR)-like symptoms. Physicians should consider an associated malignancy in PMR when patients present with atypical features such as young age, modest elevation of the sedimentation rate, and incomplete response to corticosteroids. Atypical polymyalgia rheumatica-like features like in this younger patient with relatively lower erythrocyte sedimentation rate and poor response to corticosteroid therapy may suggest the presence of an associated malignancy. © 2006 Lippincott Williams & Wilkins, Inc.
