Cutaneous angiomatosis in a dog: a case report

Abstract

A 1-year-old, castrated male mixed-breed dog presented with diffuse, purple lesions arranged in an irregular patchy pattern, with a slight elevation on the right hindlimb extending from the tarsus joint to the upper region of the thigh. Dermatological examinations and fungal and bacterial cultures revealed no infectious agents. The therapeutic response to antibiotics and antifungal agents was negative. A histopathology examination of the lesion revealed vascular proliferation with vasodilation and numerous varying-sized vessels. Mast-cell-dominated perivascular cuffing was also noted. The dog was diagnosed with cutaneous angiomatosis due to diffuse lesions and the histopathology findings of hemangioma.

Magnetic Resonance Imaging and Ultrasonographic Evaluation of Canine Tarsus

“…The tarsus is composed of various bones, and fractures and bone tumors have been reported; therefore, bone assessment was included (9). In the case of blood vessels, reports of hindlimb angiomatosis were considered (14). Specifically, the assessment focused on the saphenous lateral vein, which is a size that allows for ultrasound evaluation (19).…”

Cutaneous angiomatosis‐like presentation in koi carp (Cyprinus carpio koi): Clinical–pathological investigations

“…In veterinary medicine, angiomatosis can affect various organs and tissues of domestic and wild animal species, including, cats, horses, cows, llamas, and dolphins (Cerri et al, 2019; Leitzen et al, 2020). Cutaneous angiomatosis is a proliferative lesion of the vascular tissue involving the dermis and subcutis of dogs (Koo et al, 2021). It is considered rare, with little information on its causes, clinical behaviour, and treatment options.…”
