Parachordoma is a rare entity with an unknown origin, which reported nearly in 60 cases. We are reporting an aggressive tumor that has two recurrences in 5 months in different sites. A 49 year old male admitted with right inguinal pain that underwent a computed tomography, revealed a 52x50 mm tumor at the right inguinal subepidermal region. After the resection, pathology of the mass was parachordoma. Four months after the operation, patient admitted with a solitary mass in the right testis. Ultrasonography revealed four different masses in the right inguinal and right testicular region. Second pathology results were also parachordoma. One month later the second operation, patient again admitted to hospital with right hip pain, had a solitary mass on the collum femoris in the magnetic resonance imaging consulted for radiotherapy. Parachordoma is a rare, benign entity that must be closely followed up. The physician must be aware of the malignancy especially in the first year with existence of recurrence and metastasis. Radiotherapy is recommended after maximal resection of tumor especially in metastatic cases.
