Endocardial neoplasms are uncommon in veterinary species with most cases restricted to endocardial schwannomas in aged rats. A 15-year-old male rosy-billed pochard (Netta peposaca) was diagnosed following necropsy with numerous, proliferative endocardial masses. Histologically, these masses were composed of interlacing streams and bundles of neoplastic spindle cells supported by a fine fibrovascular stroma. Rare areas of cellular and nuclear palisading were present in the nodules. Approximately 60% of the neoplastic cells were strongly positive for S-100, whereas none of the neoplastic cells was positive for desmin, synaptophysin, neurofilament, and glial fibrillary acidic protein. The histologic features coupled with the S-100 immunoreactivity led to a diagnosis of endocardial neurofibroma.
