Background: In humans, figurate erythema (FE) represents a heterogenous group of dermatoses with circular or serpiginous erythematous skin lesions; FE has not been reported in cats. Objectives: To report clinical and histological characteristics and outcomes of FE in sphynx cats from Baltic sea‐bordering countries. Animals: Eleven client‐owned sphynx cats with FE. Materials and Methods: We recruited cases meeting the following criteria: (i) a sphynx breed, (ii) FE with or without scaling, (iii) a chronic, waxing‐and‐waning course lasting longer than a month and (iv) an absence of other skin diseases. Results: Of 11 cats, there were seven Donskoys, one Peterbald, one Ukrainian Levkoy and two presumed Canadian sphynxes; all except one were males, and the age of onset was <12 months in eight cats. Skin lesions lasted between 1.2 and 56 months, and they consisted of erythematous plaques with a linear‐to‐serpiginous, annular, gyrate or iris configuration predominating on the trunk and extremities. Scaling was often seen trailing the edge of the centrifugally expanding erythema. All cats were otherwise asymptomatic or mildly pruritic. Dermatophytosis was ruled out by special stains and/or fungal cultures in eight cats. Microscopic lesions revealed focal, mild‐to‐moderate epidermal hyperplasia and hyperkeratosis, minimal‐to‐mild dysplasia and subepidermal collagen smudging. Special stains were negative for dermatophytes. The clinical remission of FE was not achieved with diet changes or medical interventions; yet, a spontaneous, transient, partial or complete improvement occurred in most cats. Conclusion and Clinical Relevance: This is the first report of FE in sphynx cats from Eastern Europe. [ABSTRACT FROM AUTHOR]
