ABSTRACT
An adult male pygmy sperm whale (Kogia breviceps) was stranded within a tidal pool on Fernandina Beach on the north Florida Atlantic coast (USA) and expired soon after discovery. Necropsy findings included a small intestinal mass markedly expanding the intestinal wall and partially obstructing the lumen. This finding likely led to the malnutrition and ultimately the stranding of this whale. The differential diagnoses for the mass based on gross evaluation included a duodenal adenocarcinoma, leiomyoma/sarcoma, gastrointestinal stroma tumor, and benign/malignant peripheral nerve sheath tumor, previously referred to as neurofibromas or schwannomas. The mass was presumptively diagnosed as a leiomyosarcoma via routine histopathology and confirmed by immunoreactivity for desmin and smooth actin (SMA). KIT, a gene name for CD 117, was negative, excluding a gastrointestinal stromal tumor (GIST). Leiomyosarcomas have been reported within numerous wild and domestic species, although this is the first reported case of any neoplasm in a pygmy sperm whale (K. breviceps).
