RARE CASE OF FETAL ADENOCARCINOMA OF LUNG

Well-differentiated fetal adenocarcinoma (WDFA) is a very uncommon malignant tumor originating in the lung. We report the case of a 26-year-old male with a chance detection at chest x-ray of a well defined mass in the right lower lobe during a medical examination. The patient was suffered from a flu syndrome, with cough and fever. He was a nonsmoker. Computed Tomography scan showed large growth at right lower lobe with intra bronchial component in superior and medial, basal segment bronchi with no mediastinal lymphadenopathy. CT Guided FNAC report s/o Neuroendocrine tumor (likely to be carcinoid). He underwent bronchoscopy which shows vascular growth at right lower lobe. Right posterolateral thoracotomy with lower lobectomy was performed. A pathologic diagnosis of well differentiated fetal adenocarcinoma of the lung was made. Fetal Adenocarcinoma is a rare tumor, with a relative incidence estimated to be no more than 0.5% of all lung cancers. Few cases of this type of malignancy were reported in literature.
