Abstract:
An 8-yr-old female paca (Agouti paca) was admitted at the Veterinary Hospital of the Belo Horizonte Zoo (Brazil) with an ulcerated cutaneous nodule of approximately 1.5 cm in diameter in the left ear. One week later, other cutaneous nodules were detected in various body locations. The animal died during a surgical procedure to remove the tumors. All cutaneous nodules were histologically similar with features of squamous cell carcinoma. Considering the predominant in situ nature of the lesion as well as its multicentric localization, the disease reported here closely resembles Bowen's disease, which has been described in humans and which has been identified as a rare neoplastic disease of cats, with one single report in a dog. This is the first report of a neoplastic disease in Agouti

Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
