Background: Pigmented villonodular synovitis (PVNS) is an uncommon entity that mostly involves larger joints like the knee and hip. The condition presents with synovial thickening and proliferation into the growth of the variable sizes, and the exact etiology is still not clear. Pigmented villonodular tenosynovitis (PVNTS), a variant, is the condition arising from the tendinous tissues. Its presentation as a lump over a singular toe is a rare occurrence. Case description: We hereby report a case of a mass over the left fourth toe of a young lady, with minimal clinical complaints except for difficulty in wearing footwear. Magnetic resonance imaging (MRI) was followed by excision biopsy, leading to the final diagnosis of PVNTS. Uneventful healing of the wound and no complication or recurrence were noted in the follow-up of 13 months. Conclusion: Mass lesions may occasionally present at unusual sites and require histopathological evaluation for an appropriate diagnosis. Clinical significance: Pigmented villonodular tenosynovitis should be kept as an uncommon differential diagnosis in cases of the lump affecting the foot and ankle region.
