  • Title: Cutaneous angiomatosis in a llama (Lama glama).
    Author: Luppi MM, Malta MC, Ocarino NM, França SA, Serakides R.
    Journal: J Comp Pathol; 2010; 142(2-3):223-7. PubMed ID: 19740480.
    Abstract:
    Cutaneous angiomatosis was diagnosed in an adult female llama (Lama glama). Lesions were raised or plaque-like, erythematous, firm to soft in consistency and were observed on the face and skin of the axillary, abdominal, perineal and inguinal regions. The lesions were not painful or pruritic. Microscopical examination revealed an irregular parakeratotic lamellar hyperkeratosis associated with diffuse proliferation of arterioles and venules in the superficial dermis. Immunohistochemical analysis determined that the cells forming these vessels and perivascular cells expressed factor VIII-related antigen, vascular endothelial growth factor (VEGF), CD31 and smooth-muscle alpha-actin. These studies confirmed the diagnosis of cutaneous angiomatosis.
