A case of Malignant Bronchial Carcinoid- presenting as Unilateral hyperlucent lung

Bronchial Carcinoid Tumors (BCTs) belong to uncommon group of lung tumors. They commonly affect young adults and the middle aged, the same age groups affected by other more common chronic lung conditions such as pulmonary tuberculosis, COPD or bronchial asthma. Diagnosis is commonly missed or delayed due to a low index of suspicion. Surgery is the mainstay of treatment with an excellent outcome. We present a case of Malignant Bronchial Carcinoid Tumor being treated as Bronchial Asthma for 4months, which later proved to be carcinoid tumor. On perusal of previous records, CT chest showed unilateral hyper translucency with a suspicious opacity. Repeat CT chest showed endobronchial mass with post obstructive pneumonitis. HPE following endobronchial biopsy was suggestive of carcinoid tumor. Diagnosis was confirmed by immunohistochemistry.
