Intra bronchial mucoepidermoid carcinoma in an 8 year old girl: A case report of rare tumor with review of literature

• Intra bronchial + intra tracheal tumors very rare-pediatric age group.
• Primary pulmonary MEC – only 55 cases reported.
• 8 yr F-recurrent LRTI-CT mediastinal mass-exploration MEC-mass excised completely.
• No chemo/radiotherapy required, disease free @1-yr f/u.
• Radiodiagnosis > biopsy > complete resection > long-term survival good in low-grade MECs.

Intra bronchial and intra tracheal tumors are very rare in pediatric age group. Most of the literature clubs primary pulmonary tumors with these; hence actual incidences are not well defined. Amongst this mucoepidermoid carcinoma (MEC), whether low or high-grade account for only 0.1–0.5% of lung carcinomas. We report such a rare case of an eight year old girl presenting with history of recurrent lower respiratory tract infections with respiratory distress. CT scan of chest was suggestive of a mediastinal mass. She underwent rigid bronchoscopic biopsy, histopathology showed it to be mucus gland adenoma. She underwent right thoracotomy with complete excision of mass along with right lower lobectomy. Histopathology reported it to be a low-grade MEC with clear margins. She did not require any chemotherapy or radiotherapy and has no recurrence at 1-year follow up.
