Computed Tomography scan and Magnetic Resonance Imaging studies demonstrated well-circumscribed lesions in the proximal humerus followed by a similar lesion in the frontal bone of the skull. Microscopic examination revealed variable numbers of pale-staining histiocytes with emperipolesis and background lymphoplasmacytic infiltrate and fibrosis. Immunohistochemical studies revealed positive staining of these histiocytes for S100 and CD6.. View More»
