Plain-English summary
A female standard Schnauzer was brought to the vet with multiple dark, thickened skin patches on her head, neck, trunk, ears, and legs. Despite trying a systemic retinoid treatment, there was no improvement in her condition. This case is notable as it is only the second reported instance of this specific skin lesion, known as linear organoid nevus, in dogs. Unfortunately, the treatment did not help the dog, and the skin lesions remained unchanged.

Abstract
A skin lesion classified as linear organoid nevus is reported in a female standard Schnauzer. The dog was brought to the clinic with multiple hyperpigmented, hyperkeratotic linear or ovoid plaques on the head, neck, trunk, ears, and limbs. Histological findings included severe orthokeratotic hyperkeratosis, focal parakeratosis and hyperplasia of both the epidermis and the follicular infundibular epithelium, and marked sebaceous hyperplasia. No improvement was noted with systemic retinoid therapy. This is the second linear organoid nevus described in a dog, and the first report of retinoid therapy for this disease.
