BACKGROUND
Splenic lymphoma is commonly reported in domestic ferrets (), but very rarely reported in wild species, including otters. One report described B-cell splenic lymphoma in an Asian small-clawed otter () that metastasized and was the primary reasoning for humane euthanasia (Stedman and Mills, 2014).
CASE DESCRIPTION
The current report describes a case of splenic T-cell lymphoma in a captive North American river otter (). The otter died several weeks after splenectomy and no evidence of metastasis was found on gross necropsy or histopathological evaluation.
CONCLUSION
The splenectomy performed on this individual was presumptively curative for its splenic lymphoma. Extensive myocardial fibrosis was found, and suspected to have caused severe cardiac arrhythmia leading to acute death.
背景
脾淋巴瘤在国内雪貂中常见（），但在野生种中很少见，包括水獭。有一份报告描述了一只亚洲小爪水獭（）的 B 细胞脾淋巴瘤转移，这是人道安乐死的主要原因（Stedman 和 Mills，2014）。
病例描述
本报告描述了一只圈养的北美河獭（）脾 T 细胞淋巴瘤病例。这只水獭在脾切除术后数周死亡，大体剖检和组织病理学评估均未发现转移的证据。
结论
对该个体进行的脾切除术对其脾淋巴瘤具有推测的治愈作用。发现广泛的心肌纤维化，怀疑其导致严重的心律失常，导致急性死亡。
