VATS approach for pulmonary sclerosing pneumocytoma: a case report

Pulmonary Sclerosing Pneumocytoma (PSP) is a rare type of benign lung tumor usually encountered in middle-aged Asian women. The lesion is mostly found on routine chest x-rays. Though surgery is recognized as the recommended treatment, there is no consensus on the standard operative procedure for this tumor.

We report a case of a 48 year-old Caucasian woman who presented with a right para-hilar mass mimicking a hydatid cyst. After an unsuccessful initial treatment with oral Albendazole, and a steady growth over 10 years, the patient was programmed for surgical resection by video-thoracoscopic (VATS) approach. We were able to completely resect the tumor by VATS. Histopathological analysis suggested the diagnosis of Pulmonary Sclerosing Pneumocytoma. No further treatment was required and the patient was rapidly discharged.

Pulmonary sclerosing pneumocytoma is a rare form of benign tumor that should be part of the differential diagnosis of lung lesions of unknown origin. Because of its well-defined encapsulated structure allowing total enucleation, VATS can be proposed as a less invasive alternative to classic thoracotomy.
