Resumo

Background: Glucagonomas are very rare neuroendocrine tumors of pancreatic endocrine islets alpha cells and they produced excessive amount of glucagon hormone. Necrolytic migratory erythema (NME) is a rare dermatosis that characterized by erosive, ulcerative and crusted lesions in different sites of the skin and the common cause of this situation related to glucagon secreted tumors. NME can occur commonly in man but some rare and recent reports available the occurrence of this situation in pet animals especially dogs. Both gross and histological findings in both human and animals are similar. This paper reports a NME case with glucagonoma and diabetes mellitus (DM) by clinical, histopathological and immunohistochemical examinations. Case: A 12-year-old, cat presented with complaints of skin lesions in neck region, hyperglycemia, weight loss and history of anorexia during the 2 months. Biochemical analysis results revealed high glucose, aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) and creatinine levels but decreased blood urea nitrogen (BUN), total protein and potassium levels. After 2 weeks of anti-diabetic drug treatment, the blood glucose level became normal and skin lesions ameliorated but anorexia and weight loss continued. The cat exhibited general weakness and pain in abdominal area. Although the clinical sings ameliorated and skin lesions and serum biochemical findings returned the relatively normal levels compared the admission, the cat died after 2 weeks of treatment and necropsy performed. At necropsy, marked cachexia, loss of skin elasticity and decreased skin thickness were observed. During the examination of abdominal cavity of the cat, there was a mass 0.5x0.5 cm in diameter, hard and grayish color was diagnosed at the pancreas...(AU)
