Mature adult fat cells, ropey collagen, and a spindle cell component is consistent with a spindle cell lipoma in lesions appearing within the cape-like distribution of the neck, shoulders, and back. These lesions are CD34 positive and S100 negative. The presence of floret-like multinucleated giant cells would be consistent with pleomorphic lipoma, an otherwise clinically and prognostically identical lesion. |
