|A 63-year-old male had a bone tumor within his left middle finger.|
The amputated finger measures 12.0 cm long with enlargement of the proximal two thirds, which measures up to 3.5 cm in diameter. Sectioning through the specimen reveals a well-demarcated cystic tumor in the center of the specimen involving the bone. The tumor measures 1.5 x 1.5 cm and the cut surface is gray-tan and multicystic.
