Undifferentiated Pleomorphic Sarcoma of the Thigh: Diagnostic Pitfalls and Complex Reconstruction
摘要
Soft tissue sarcomas (STS) constitute an uncommon and heterogeneous group of tumors of mesenchymal origin, with an estimated incidence of five cases/per 100,000 inhabitants/year in Europe [1]. They comprise approximately 1% of malignant tumors. There are more than 50 subtypes that need radiological and pathological correlation [2]. The diagnostic pathway should always start with thorough patient history documentation. Lumps that have not changed in size or shape over the years are most likely benign, whereas recently noticed, constantly enlarging may be malignant.
