Plain-English summary
Two young and two adult cats were diagnosed with a skin condition called perforating dermatitis, which caused painful bumps and plaques on their skin. These lesions had a yellow-orange plug in the center and could bleed when the plugs were removed. While vitamin C didn't help in two cases, treatment with a steroid medication called methyl-prednisolone acetate worked well for managing symptoms, and in one case, it seemed to completely cure the condition. Unfortunately, the fourth cat was lost to follow-up after diagnosis.

Abstract
The clinicopathological findings of perforating dermatitis in two young and two adult cats are described. In all cases, the lesions were characterized by single or multiple papules and plaques, 0.5-3.0 cm in diameter, each containing a central, firm, exophytic, cone-shaped, yellow-orange keratotic plug, tightly adherent to the underlying skin. Removal of the protruding material was associated with bleeding and left the ulcerated surface exposed. In one case, the lesions showed a linear configuration and identical lesions occurred on the suture sites following biopsy. Histopathologically, the diagnosis was straightforward because of the presence of vertically orientated collagen bundles extruded from ulcerated, concave-shaped invaginations of the skin. In two cases, vitamin C administration failed to resolve the disease. In two cases, methyl-prednisolone acetate was used to manage relapsing episodes and vitamin C helped to reduce glucocorticoid requirements. In one case, treatment with methyl-prednisolone acetate only appeared to be curative. The fourth case was lost to follow-up immediately after the diagnosis.
