摘要

Lipoma and Angiolipoma: Lipomas, the most common soft tissue tumor of adults, rarely present before the third decade of life. Lipomas usually appear as slowly growing, solitary or rarely multiple, subcutaneous, occasionally deeply seated (intramuscular or intermuscular lipoma) masses. Smears from lipoma are identical to those from normal adipose tissue (Fig. 1). The presence of other mesenchymal elements such as metaplas-tic bone and cartilage, fibrotic tissue (fibrolipoma), or de-generative/myxoid areas (myxolipoma) is very occasionally seen in fine-needle aspiration (FNA) smears. Angiolipomas occur commonly in young adults as small (usually smaller than 2 cm), well-delaminated, often multiple and tender subcutaneous nodules. FNA smears of angiolipomas do not differ from smears of regular lipomas.
