A four-year-old spayed female mixed breed dog presented to Cornell's Dermatology Service for evaluation of perivulvar pruritus. The owner reported a history of chronic intermittent pruritus associated with the perineum, anus and perivulvar region. The pruritus was reported to be non­seasonal and relapsed despite treatment. Physical examination revealed vulvar intertrigo and mild erythema on the lateral aspects of the vulva. The remainder of the exam was umemarkable. Problem list included intertrigo and recurrent perivulvar dermatitis. Differential diagnoses included: perivulvar dermatitis (secondary to vulvar intertrigo ("recessed", "hooded" or "inverted juvenile vulva"), atopic dermatitis, vaginitis, anal sacculitis, neoplasia, and parasites (secondary to the vulvar intertrigo). Diagnosis ofvulvar intertrigo with secondary perivulvar perivulvar dermatitis or surgical correction ofvulvar intertrigo. Surgical correction is commonly the treatment of choice but medical management may be a realistic option for some patients.
