The synovial sheath cell tumor (TCGGS) represents the localized form of hemo pigmented villonodular synovitis, which remains a rare tumor in our practice. It occurs mainly in young adults with a predominance of women. It mainly affects the fingers of the hand, its location at the level of the thenar compartment is very rare. Clinically, it has a local expression, which can be summarized as a swelling characterized by slow growth and which may be accompanied by signs of compression at a late stage. An anatomo-pathological examination remains the key element in diagnosis and prognosis. Treatment is based on surgery with complete tumor removal. We report the case of TCGGS of the thenar compartment with compression of the median nerve.
