|Eight cases of feline plasma cell pododermatitis, collected over a 3-year period, were studied using histological (haematoxylin and eosin), histochemical (methyl green-pyronin) and immunohistochemical (antibody against lambda light chains of immunoglobulins) techniques. No sex, breed or age predisposition, or paw predilection was observed.
The disease began as a swelling of the footpads, followed by ulceration. Histologically, lesions were characterized by the presence of a large number of plasma cells in a predominantly perivascular pattern. Binucleated plasma cells and mitotic figures were observed.
Clinical follow-up for over 1 year revealed total remission of the lesions both after glucocorticoid therapy in four cases, and total surgical excision in two animals. Follow-up studies were not possible in one case.
