An unusual case of Pigmented Villo-Nodular Synovitis of the second toe: A case report and review of literature.

Pigmented villo-nodular synovitis (PVNS) is a common disease entity particularly in the knee joint but its incidence in the foot is quite rare. A case of PVNS of the second toe that presented at the outpatient department with an insidious onset and slowly progressive painful swelling of the toe associated with stiffness is presented. The mass was subsequently excised and the diagnosis confirmed by histo-pathology samples. The patient's symptoms improved significantly after the operation. This case is one of the very few reported cases of PVNS involvement of flexor tendon sheath of the foot. It also signifies the importance of clinical suspicions based on the symptoms and examination in reaching to the presumptive diagnosis of the foot pathology and its confirmation by histo-pathological evaluation.
