Clinical Image

Thymolipomas are rare benign tumors, constituting one of the differential diagnoses of an anterior mediastinal mass. These tumors may run an indolent, asymptomatic course, often achieving massive dimensions before presentation. Once Symptomatic, respiratory symptoms predominate.
We report a case of thymolipoma in a 30 years old male complaining of heaviness and constricting type of chest pain and neck swelling of 1 year duration. CT scan findings were a space occupying lesion in the anterior mediastinum and extend to right side of mediastinum, neck and left side hemithorax. The tumor was completely excised through ‘Postero lateral thoracotomy’. Histopathological examination confirms the diagnosis Thymolipoma. This is the second case we have reported from our institution (4).
