Abstract

Carcinoid is one of the most common tumors of the gastrointestinal tract followed by the tracheobronchial tree. Bronchial carcinoid compromises 20% of total carcinoid and accounts for 1–5% of pulmonary malignancies. Carcinoid can be typical or atypical, with atypical carcinoid compromises 10% of the carcinoid tumors. Carcinoid usually presents as peripheral lung lesion or solitary endobronchial abnormality. Rarely it can present as multiple endobronchial lesion. We hereby present a rare case of an elderly gentleman who had undergone resection of right middle and lower lobe of lung for atypical carcinoid. Seven years later he presented with cough. CT scan of chest revealed right hilar mass. Flexible bronchoscopy revealed numerous endobronchial polypoid lesions in the tracheobronchial tree. Recurrent atypical carcinoid was then confirmed on biopsy.

Highlights

The most common location of carcinoid tumors is the gastrointestinal tract, followed by the tracheobronchial tree [1]
We hereby present a case of 63-year-old male who presented with recurrence of carcinoid seven years after curative resection of his carcinoid
Carcinoid tumors are neuroendocrine tumors that typically arise from gastrointestinal tract and the bronchus

Summary

Introduction

The most common location of carcinoid tumors is the gastrointestinal tract, followed by the tracheobronchial tree [1]. Bronchial carcinoids are low-grade neuroendocrine malignant tumors that comprise 1–5% of all lung neoplasms [2,3,4]. It used to be felt as a benign tumor but when distant metastases happen, it tends to be less aggressive than the noncarcinoid lung malignancies [5,6,7]. In 2004, new criteria divided lung carcinoids into different groups: typical and atypical carcinoids, large cell neuroendocrine carcinoma, and small cell lung carcinoma [8]. The typical is much more common than the atypical type (90% versus 10%) [9]. We hereby present a case of 63-year-old male who presented with recurrence of carcinoid seven years after curative resection of his carcinoid
