Intrathoracic extrapulmonary hemangiopericytoma. Late local recurrence after radical extirpation of a large tumor.
A 39-year-old woman was operated upon for an extremely large hemangiopericytoma located in the right hemithorax. During intensive follow-up a local recurrence was observed 8 years after the radical extirpation of the well-encapsulated tumor, histologically assessed as generally benign. This and other observations give reason to suspect that the well-recognised puzzling clinical behavior of this rare tumor is a result of a potential pathological capacity of the abnormally vascularised fatty connective tissue through which the tumor is connected to the body. This tissue, if not radically extirpable, must be completely destroyed in some way during or after the operation in order to prevent recurrence.
