title: [A man with a nodule on his thumb].
abstract: A 60-year-old man presented with a recurrent translucent nodule on the dorsum of the left thumb. After puncturing, a clear gelatinous fluid appeared. The diagnosis was digital mucous cyst. These cysts commonly result from joint fluid leaking from an osteoarthritic distal interphalangeal joint through a communicating canal.
