Localized Scleroderma Morphea-Like in a Cat

This case report described a rare instance of localized scleroderma (morphea-like) in a 4-year-old Persian cat, which presented with chronic pruritus and alopecic lesions. Unlike the two previously reported cases in cats, this case did not achieve clinical resolution or spontaneous remission following treatment. The lesions were characterized by circular, alopecic patches with a hyperemic halo and smooth, pigmented centers. Despite various treatments, including antibiotics and pentoxifylline to stimulate hair growth, the lesions remained unchanged. Histopathological evaluation confirmed dermal collagen proliferation consistent with morphea, but the cause of pruritus remained undetermined, and it was unclear if it was primary or secondary to the skin condition. This case highlighted the unpredictable nature of the disease and its resistance to treatment.
