Abstract We report a case of mediastinal atypical carcinoid in a 63-year-old woman with neurofibromatosis type 1 (NF-1), who presented with shortness of breath and a bulky mediastinal mass. Initial consideration was given to a neurogenic tumor. However, on thoracoscopic biopsy, the histologic appearance was consistent with an atypical carcinoid. Carcinoid tumors have been reported in association with NF-1 previously, but commonly in such unusual sites as the ampulla of Vater and duodenum and not in the thorax. The bulky, extensive, and highly vascular nature of the lesion precluded resection or debulking surgery. To our knowledge, there are no previous reports of atypical carcinoid of the lung or mediastinum in a patient with neurofibromatosis. This case report, therefore extends the spectrum of solid neoplasia in general and carcinoid tumors in specific, as they occur in association with NF-1.

Somatostatinomas are rare neuroendocrine tumours, mostly located in the pancreas or duodenum, with an estimated incidence of 1 in 40 million. Duodenal somatostatinomas (DSs) are usually found in association with neurofibromatosis type 1 (NF1), tuberous sclerosis and Von Hippel-Lindau syndrome. Gastrointestinal stromal tumours (GIST) have also been described in NF1, but the association with somatostatinoma is very uncommon. We report the case of a patient with NF1 who presented with obstructive jaundice due to multiple firm nodules around the ampulla of Vater. A pancreaticoduodenectomy was performed and revealed a 1 cm duodenal/ampullary mass which stained positive for somatostatin, together with a GIST also found on the duodenal wall. Despite its rarity, ampullary somatostatinomas should be considered in the differential diagnosis of biliary tract dilation in patients with NF1.
