case_images: The mass was 13 mm in diameter [Figure 1], with mild tenderness and firm in palpation, slightly mobile and, without marked movement on interphalyngeal motion, and no obvious adhesion to adjacent skin.

case_images: CT-scan of the index finger. Conventional posteroanterior and lateral radiography revealed a paraosteal sclerotic lesion just abutting middle phalanx with bone density similar to adjacent bone and slight periosteal reaction [Figure 2], and further evaluation with CT-scan noted that the lesion has a patchy irregular border without cortical destruction or sauccerization and there is no typical zonal pattern in the lesion [Figure 3].
