title: Pulmonary blastoma.
abstract: A three-and-half-year-old boy presented with recurrent chest infections, fever and weight loss of three month duration not responding to antibiotics. The chest X-ray and CT scan revealed a large well-circumscribed mass in right upper thorax with collapse of right upper lobe. A preoperative diagnosis could not be made even after fine needle aspiration cytology. Thoracotomy and right upper lobectomy was done and the biopsy report was an inflammatory pseudotumor. The child remained well for three months after which his symptoms and the mass recurred. The histopathology slides were reviewed and revealed a biphasic malignant tumor suggestive of Pulmonary Blastoma (PB). Patient received four cycles of chemotherapy followed by re-exploration. The recurrent tumour could only be excised partly and the child succumbed to persistent shock postoperatively. The final histopathological diagnosis was confirmed as PB. Primary pulmonary neoplasms in children are rare and of these PB which is even rarer, constitutes less than 15%. The report highlights that the lack of familiarity with this entity still causes error in the diagnosis of PB.
