Glucagonoma-Associated Rash - The rash involved the arms, genitals, and buttocks and had progressed to the legs (Panel A). Computed tomography of the abdomen showed a 9-cm mass arising from the pancreatic head (Panel B, arrow). A pancreaticoduodenectomy was performed, and pathological examination of excised tissue revealed a well-circumscribed, low-grade neuroendocrine neoplasm that was consistent with a glucagonoma (Panel C). Within 5 days after surgery, the rash on the legs began to resolve (Panel D) #Clinical #HONC #Derm #Pathology #Radiology #Glucagonoma #Rash #Microscopy #CT #NEJM
