Bronchioloalveolar cell carcinoma presenting as a “non-resolving consolidation” for two years
open access
Abstract
Bronchioloalveolar carcinoma (BAC), a rare form of lung malignancy, is usually seen in non-smokers and women. Three distinct histological forms have been identified viz, mucinous, non-mucinous and mixed or indeterminate. The mucinous variety of BAC may present as a consolidation which is very difficult to differentiate from an infective pneumonia. We present a case of a middle aged female who was evaluated for a “non-resolving consolidation” for a period of two years. She had undergone an inconclusive bronchoscopy and had received several courses of antibiotics including anti-tuberculous therapy without relief. The size of the lesion had remained largely unchanged during this period and there was no significant clinical deterioration in the patient. Transbronchial biopsy done on presentation revealed BAC of the mucinous variety. BAC presenting as a large consolidation without significant change for a period of two years has rarely been documented in the literature.
