Synchronous Papillary Carcinoma and Hemangiopericytoma with Lung Metastases

الملخص EN

Hemangiopericytomas (HPC) are uncommon tumors that originate from perivascular cells of capillary vessels.

HPC are about 1% of all vascular tumors and can be found in the head-neck region with an incidence between 16% and 33%.

HPC is a neoplasm of uncertain malignant potential; it can behave as an aggressive tumor with metastases and increased mitotic activity or as a relatively benign neoplasm with only local development.

In this paper we describe a case of hemangiopericytoma with uncertain malignant potential with cervical location associated with a concomitant papillary thyroid carcinoma and lung metastasis of unknown origin; this case led us to follow a specific and uncommon diagnostic and therapeutic strategy.
