title: Epitheliotropic lymphoma in a squirrel (Sciurus sp.).
abstract: A 12-yr-old, intact male squirrel (Sciurus sp.) presented with a 15 mm-by-20 mm area of alopecia and plaque-like dermal thickening over the left caudolateral thorax. Routine diagnostic tests ruled out more common conditions that result in alopecia, such as dermatophytosis and acariasis. A punch biopsy was obtained under anesthesia and submitted for histopathologic evaluation. The diagnosis of epitheliotropic lymphoma was made, and follow-up surgical excision was performed. Histopathologic features were consistent with epitheliotropic lymphoma, and immunohistochemistry confirmed a T-cell origin. There was no local recurrence, new lesions, or evidence of metastasis 10 mo after surgical excision. To our knowledge, to date, epitheliotropic lymphoma has not been described in a squirrel.
