Low-grade fibromyxoid sarcoma (LGFMS) is a subtype of sarcoma that commonly arises from the deep soft tissue. We present a case of LGFMS originated from the penoscrotal junction area, which highlights the unusual site of LGFMS presentation.The patient presented with a mass in the left base of the penis, which was resected and the pathology report was compatible with LGFMS. However, local recurrence near the primary tumor site was detected 3 months postoperatively, and re-excision confirmed the same diagnosis. This is the first report of LGFMS in the penoscrotal junction area as an uncommon site of this tumor.

低度恶性纤维黏液样肉瘤（LGFMS）是肉瘤的一种亚型，通常起源于深部软组织。我们报告一例起源于阴茎阴囊交界处的LGFMS病例，该病例突出了LGFMS这种不常见的发病部位。患者因阴茎左侧根部肿物就诊，肿物切除后病理报告符合LGFMS。然而，术后3个月在原肿瘤部位附近检测到局部复发，再次切除后确诊相同诊断。这是首例关于LGFMS发生于阴茎阴囊交界处这一不常见部位的报告。
