CUTANEOUS LYMPHOMA

Clinical Presentation

While lymphoma is a common cancer in dogs, the cutaneous form is very rare and accounts for only 3-8% of all canine lymphomas (3,17). Cutaneous lymphoma usually is seen in middle aged to older dogs ranging from 5 and 11 years of age (25). Unlike other round cell tumors, cutaneous lymphoma usually presents as multiple tumors on the skin as opposed to a solitary mass. Cutaneous lymphoma is divided into epitheliotropic and nonepitheliotropic forms. Epitheliotropic lymphoma is also known as mycosis fungoides (MF), so named because of the mushroom-like morphology of the tumors in humans (3). Early stages of epitheliotropic lymphoma can resemble inflammatory skin disease including erythema, scaling, pruritis, depigmentation, alopecia, plaques, ulceration, and crusting. Many dogs are presented with a history of chronic skin disease. The skin lesions may be focal or generalized. Dogs presented with advanced epitheliotropic lymphoma usually have multiple tumors that can occur anywhere, but appear to have a predilection for mucocutaneous junctions and the oral cavity (3,17). Metastasis to lymph nodes and other organs occurs, so dogs may present with lymphadenopathy and other signs of systemic disease (17).

Nonepitheliotropic lymphoma is extremely rare in dogs (but is the more common form of cutaneous lymphoma in cats). It may represent metastatic disease to the skin or a primary skin neoplasm. Multiple, ulcerated, skin nodules are usually observed in this form of the disease. Nonepitheliotropic lymphoma is generally unassociated with erythema, pruritus, and scaling (17).
