Aggressive angiomyxoma is an uncommon neoplasm that preferentially involves the pelvic and perianal regions of reproductive age females. These tumors are rare in men and merit a wider recognition in male urologic pathology. We report a case of a 65 year old male who presented with a swelling in the left perineal region since 2 years which gradually increased in size to 10 x 10 x 8 cms. CT scan revealed a well defined lobulated heterogenous minimally enhancing mass in the left ischiorectal fossa extending upto the subcutaneous plane. Microscopically stellate to spindle shaped cells arranged in a loose myxoid stroma with numerous thin to thick walled vessels were seen. There was no evidence of pleomorphism, hyperchromatism or mitotic activity. This case is reported because of its rarity in males. It is a benign tumor and requires a wide excisional surgery.
侵袭性血管黏液瘤是一种罕见的肿瘤，好发于育龄期女性的盆腔和肛周区域。这些肿瘤在男性中罕见，在男性泌尿病理中值得更广泛的认识。我们报告一例65岁男性患者，自2年前起左侧会阴区出现肿胀，肿物逐渐增大至10×10×8厘米。CT扫描显示左坐骨直肠窝有一个边界清晰的分叶状不均匀低密度肿块，最小限度强化，延伸至皮下平面。显微镜下可见星状至梭形细胞排列在疏松的黏液样基质中，有许多薄壁至厚壁血管。未见多形性、核深染或有丝分裂活性的证据。报告此病例是因其在男性中罕见。这是一种良性肿瘤，需要广泛切除手术。
