Article history The Mongolian gerbil (Meriones unguiculatus), also known as Mongolian jird, is a rodent of the family Cricetidae. One of its most noticeable anatomical characteristics is the presence of ventral and dorsal scent glands, the former located in the abdominal region. The present study aimed at describing an incidence of squamous cell carcinoma (SCC) of the ventral scent gland in the species. A two-year-old animal characterized by an increased volume in the ventral abdominal region was treated at the Veterinary Hospital. After evaluating the macro-and microscopic characteristics of the mass tissue, a diagnosis of SCC could be confirmed. However, further studies on the physiology of neoplasms in Mongolian gerbils are needed in order to promote the well-being and longevity of individuals. Hormonal dysfunction of sexual origin is likely the most common factor associated with the occurrence of this type of neoplasm in the species.

Hamster breeding is becoming increasingly popular, mainly because of the simplicity of breeding, low cost, and characteristics of these animals: they are small, quiet, and do not require a large space. Because of this ease of keeping, some people choose to keep more than one animal of the same species in a single enclosure. In some cases, this sociability can lead to fights, because hamsters are extremely territorial animals, which can cause significant injuries. Knowledge of the most efficient methods for wound healing is essential in medicine for wild and exotic animals, as it allows faster clinical treatment and thus, stress reduction. The present case report refers to the therapeutic treatment of an extensive skin lesion in a golden hamster (Mesocricetus auratus) using ozonized sunflower oil. The treatment, which lasted 23 days, allowed complete healing of the lesion.
