Bronchial Carcinoid and Type 1 Multiple Endocrine Neoplasia Syndrome. A Case Report

Carcinoid tumours of bronchial origin are rare in type 1 multiple endocrine neoplasia (MEN1) syndrome. The prevalence of histologically confirmed cases is approximately 5–8%, although in more recent studies it is estimated that it could be much higher and a possible relationship with the presence of hypergastrinaemia is suggested. We report a patient with a type 1 MEN syndrome, with no respiratory symptoms, with hypergastrinaemia, and in whom a 5 mm diameter nodule was detected in the wall of the left main bronchus by computed tomography. The bronchial biopsy confirmed that it was a typical bronchial carcinoid and the octreoscan showed a single focus of high uptake coinciding with this lesion. A bronchoplastic (sleeve) was performed with extirpation of 3 bronchial rings, which also demonstrated that it was a typical carcinoid.
