An 8-month-old kitten is presented for raised, firm, pencil-like lesions on the caudal aspects of both hind legs. The owner reports the lesions developed rapidly but do not seem bothersome to the kitten. Dermatological examination reveals hard, linear lesions in the superficial dermis. Skin biopsies reveal eosinophilic granulomatous inflammation and collagen degeneration.
