Intrascrotal fibrous pseudotumor is rarely observed, and only 40 cases have been reported in Japan. A 65-year-old male patient visited this hospital due to a painless right scrotal mass. Computed tomography demonstrated a solid mass with a cystic component ; however, the exact location of the mass in relation to other scrotal contents was not determined. Intraoperative findings revealed a solid mass, 2 cm in diameter, in the tunica vaginalis. The mass could not be dissected from the epididymis ; therefore, high orchiectomy was indicated. A histopathological diagnosis of fibrous pseudotumor was made. The patient's postoperative course was uneventful, and no recurrence has been found. It is difficult to make a diagnosis of paratesticuler tumor based on preoperative radiological results and even macroscopic observation during surgery. We strongly recommend that it is necessary to undergo high orchiectomy for a fibrous pseudotumor in which dissection from the peripheral tissue is very difficult since it may involve various types which may lead to a diagnosis of malignancy.
阴囊内纤维性假瘤很少见，在日本仅报道过40例。一名65岁男性患者因右侧阴囊无痛性肿块前来我院就诊。计算机断层扫描显示一个伴有囊性成分的实性肿块；然而，肿块相对于其他阴囊内容物的确切位置尚未确定。术中发现鞘膜内有一个直径2厘米的实性肿块。该肿块无法从附睾上剥离；因此，建议行高位睾丸切除术。病理组织学诊断为纤维性假瘤。患者术后恢复顺利，未发现复发。基于术前影像学结果甚至手术中的大体观察，很难诊断睾丸旁肿瘤。对于难以从周围组织剥离的纤维性假瘤，我们强烈建议行高位睾丸切除术，因为它可能涉及多种类型，可能导致恶性肿瘤的诊断。
