The vast majority of cutaneous canine nonepitheliotropic lymphomas are of T cell origin. Nonepithelial Bcelllymphomas are extremely rare. The present case report describes a 10-year-old male Golden retrieverthat was presented with slowly progressive nodular skin lesions on the trunk and limbs. Histopathology of skinbiopsies revealed small periadnexal dermal nodules composed of rather pleomorphic round cells with roundor contorted nuclei. The diagnosis of nonepitheliotropic cutaneous B-cell lymphoma was based on histopathologicalmorphology and case follow-up, and was supported immunohistochemically by CD79a positivity.
