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.
