Abstract：
We present an extremely rare case of deep angiomyxoma (DAM) in the thigh that was misdiagnosed as desmoid-type fibromatosis. A 40-year-old Japanese woman presented with a mass on the left thigh. The histological diagnosis by needle biopsy was desmoid-type fibromatosis; the tumor grew slowly and was resected 4 years later. The histological diagnosis from the resected tumor was DAM. As of 16 months post-surgery, the patient has not noticed any local recurrence. Although DAM in a lower extremity is extremely rare, clinicians must be aware of its possible occurrence in areas relatively close to the pelvis.
摘要：
我们介绍了一例极为罕见的大腿深部血管粘液瘤（DAM）病例，该病例被误诊为纤维样型纤维瘤病。一名40岁的日本妇女左大腿上有一块肿块。穿刺活检的组织学诊断为纤维瘤病。肿瘤生长缓慢，并在4年后切除。切除肿瘤的组织学诊断为DAM。手术后16个月,患者没有发现任何局部复发。虽然下肢的DAM极为罕见,临床医生必须意识到它可能发生在相对靠近骨盆的区域。
