Feline lymphocytosis

From Felipedia

Feline lymphocytosis is a skin disease of cats where skin lesions are variable: usually solitary lesions.

The most frequent lesions are alopecia, erythema, and scaling. Less commonly, single or multiple nodular lesions, ulcers or excoriations. Histologically the epitheliotropism (T cell) is less marked than in the epitheliotropic lymphoma. Studies on the clonality of the lymphocytes involved in the disease suggest that this dermatitis could be considered as low-grade indolent lymphoma.
