Abstract
Eleven year-old, spayed female cat presented with the swollen metacarpal and metatarsal pads. These lesions had been gradually progressed for 5 months. Histopathologic examination revealed severe plasma cell infiltration at the dermis, and polyclonal gammopathy was recognized. Based on these findings, plasma cell pododermatitis was diagnosed. The cat had been treated with oral doxycycline chloride, 5 mg/kg BID for 7 weeks, and the skin lesions were improved. Thereafter, the cat has been disease free for 8 months.
