Malignant Large Cell Calcifying Sertoli Cell Tumor of the Testis (LCCSCTT) is a rare histological variant of sex cordstromal tumors. It usually arises in young males, sometimes is associated with endocrine abnormalities and has a benign course. It is exceptional in elderly men and the outcome is rarely fatal. We report a case of LCCSCTT in a 73 year-old man with fatal outcome. The tumor involved the right testis and several areas of the tunica albuginea were grossly invaded. Serum levels of HCG, LH and testosterone were normal. Lymphoangiography performed after orchiectomy showed an involvement of the iliac and preaortic lymph nodes. X-ray of the chest showed no lung metastases. A thorough study of the light microscopic, immunohistochemical and ultrastructural appearances was performed. Immunohistochemistry revealed positivity to vimentin, S-100 and NSE. Our observations confirm the previous findings concerning malignant LCCSCTT and point out the histogenesis of the tumor from Sertoli cells.
睾丸恶性大细胞钙化性支持细胞瘤(LCCSCTT)是性索间质肿瘤中一种罕见的组织学变异类型。它通常发生于年轻男性,有时与内分泌异常有关,病程呈良性。在老年男性中较为罕见,预后极少致命。我们报告一例73岁男性的LCCSCTT,其预后致命。肿瘤累及右侧睾丸,白膜的几个区域受到肉眼可见的侵犯。血清人绒毛膜促性腺激素(HCG)、促黄体生成素(LH)和睾酮水平正常。睾丸切除术后的淋巴造影显示髂血管和腹主动脉旁淋巴结受累。胸部X线检查未发现肺转移。对其光镜、免疫组化和超微结构表现进行了全面研究。免疫组化显示波形蛋白、S-100和神经元特异性烯醇化酶(NSE)呈阳性。我们的观察结果证实了先前关于恶性LCCSCTT的发现,并指出该肿瘤起源于支持细胞。
