A 75-year-old woman presented with a ganglion-like nodule on the dorsal aspect of the right foot. A 2.5 x 1.5 cm, saccular and malleable tumor, that was in continuity with the dorsal venous arch, was completely resected. It was characterized by a diffuse intramural and circumferential, low grade, malignant, smooth muscle proliferation with an aneurysmal-like luminal space. No endoluminal or periadventitial invasive neoplastic component was present. The patient had no evidence of disease at 58-month follow-up. This is the first reported case of venous leiomyosarcoma in the foot. Furthermore, the intramural confinement of neoplastic growth is a unique observation.
一名75岁女性因右足背出现一个腱鞘囊肿样结节就诊。一个2.5×1.5厘米、囊状且可延展的肿瘤，与足背静脉弓相连，被完整切除。其特征为弥漫性壁内及环形、低级别、恶性的平滑肌增生，伴有动脉瘤样管腔间隙。未发现腔内或外膜周围浸润性肿瘤成分。在58个月的随访中，患者无疾病迹象。这是足部静脉平滑肌肉瘤的首例报道病例。此外，肿瘤生长局限于壁内是一个独特的发现。
