Which gross findings are associated with epitheliotrophic T-cell lymphoma?

Epitheliotrophic T-cell lymphoma is characterized by its infiltration of neoplastic T-cells into the epidermal layer of the skin. This invasion leads to distinct dermatological manifestations, primarily erythema and scaling. The erythema signifies inflammation due to the immune response triggered by the malignant T-cells, while scaling reflects the disruption of normal keratinization and skin barrier function.

In this context, the presence of erythema and scaling serves as a direct indicator of the disorder's impact on the skin's structure and health. This manifestation is essential for recognizing the disease and understanding its pathophysiology, as it distinguishes epitheliotrophic T-cell lymphoma from other conditions that might present with different clinical signs. Recognizing these specific gross findings is critical for accurate diagnosis and subsequent treatment planning for affected animals.
