ABSTRACT: This case describes a metastatic Sertoli cell tumor (SCT) with lymphatic spread to the abdominal and thoracic lymph nodes, pancreas, and adrenal gland in an adult spotted seal Phoca largha. The neoplasm was composed of tubules lined by palisading neoplastic cells separated by a variably dense fibrous stroma. This pinniped was 1 of 2 cryptorchid seals and the sole case of genital neoplasia among 70 ice seals necropsied by the North Slope Borough from 2012 to 2017. Overall, SCTs are rarely reported in marine mammals.
