Cutaneous epitheliotropic T-cell lymphoma in a sugar glider (Petaurus breviceps).

A 3-year-old male sugar glider presented with pruritus and alopecia primarily affecting the back and neck regions. Dermatologic diagnostics ruled out common causes. Skin biopsies revealed cutaneous epitheliotropic T-cell lymphoma, a rare condition in sugar gliders. Despite treatment, the glider's condition worsened, leading to death. This case highlights the importance of thorough diagnostic evaluation in exotic pets.
