Figure 12c. Chondroid lipoma in the shoulder of a 40 year-old-woman with scapular pain. (a) Anteroposterior radiograph shows chondro-osseous mineralization overlying the scapula (arrows). (b) Axial T1-weighted (500/17) MR image reveals lipomatous components peripherally (arrows) and low-attenuation chondroid areas centrally (*). T2-weighted MR image (not shown) revealed diffuse high signal intensity. (c) Photograph of the axially sectioned gross specimen shows a peripheral lipomatous component (arrows) with central lobules of chondroid tissue (*). (d) Photomicrograph (original magnification, x200; H-E stain) demonstrates adult fat cells (*) and lipoblasts (arrowheads) with intermixed chondroid tissue (C).
