Bronchial Carcinoid Tumors are an uncommon type of slow-growing neuroendocrine tumors arising from bronchial mucosa.

Carcinoid tumors typically secrete hormones such as serotonin, and may lead to carcinoid syndrome, characterized by flushing, wheezing, diarrhea, and salivation.

Nests of neuroendocrine cells are seen on pathology, which stain positively for chromogranin. Prognosis is typically very good, as these tumors typically cause problems secondary to mass effect, and may be amenable to surgical resection.
