摘要

摘要精细胞肿瘤是一种罕见的睾丸肿瘤,起源于生殖细胞。其特征是由大细胞、中细胞和淋巴细胞样小细胞组成的三重细胞的组织学特征。众所周知,鳞状细胞瘤是良性的,因此简单切除后预后良好。转移性精细胞肿瘤极为罕见,通常伴有组织学变异,包括肉瘤样变化和间变性变异。然而,在这种情况下,我们报告了一个犬转移性精细胞肿瘤,没有明显的肉瘤变化和变性变体。肿块由三种细胞组成,包括具有高度多形性的大细胞、中细胞和小细胞。肿瘤细胞有一个模糊的细胞质边界和有丝分裂的图形经常被观察到。原发性精细胞肿瘤在切除后一个月转移到腹部器官,狗在手术后13个月死亡。因此,尽管精细胞肿瘤的转移很罕见,但建议在犬精细胞肿瘤手术切除后仔细随访。

A Rare Case of Canine Metastatic Spermatocytic Tumor without Sarcomatous and Anaplastic Variants
Abstract Spermatocytic tumor is a rare testicular tumor, which is originated from gonocytes. It is characterized by the histological feature of tripartite which is composed of large, medium, and lymphocyte-like small cells. It is well-known that spematocytic tumor is benign, thus a good prognosis is expected after simple resection. Metastatic spermatocytic tumor is extremely rare and usually accompanied by histological variants including sarcomatous changes and anaplastic variants. In this case, however, we report a canine metastatic spermatocytic tumor without prominent sarcomatous changes and anaplastic variants. The mass was composed of three kinds of cells including large, medium, and small cells with high pleomorphism. The neoplastic cells had an indistinct cytoplasmic border and mitotic figures were frequently observed. The primary spermatocytic tumor metastasized to the abdominal organs one month after the resection, and the dog died 13 months after the surgery. Thus, careful follow-up is recommended after surgical resection of canine spermatocytic tumor even though metastasis in spermatocytic tumors is rare.
