BACKGROUND: Digital mucous cyst (DMC) is a common benign condition, but consensus has not been reached regarding its pathogenesis and treatment. OBJECTIVE: This review provides a concise overview of DMCs. METHODS: The review presents the literature pertaining to the etiology, pathogenesis, classification, clinical features, epidemiology, differential diagnoses, diagnosis, and management of DMCs. RESULTS: DMCs have a predilection for middle-aged patients, a good prognosis, and a high recurrence rate. DMCs may occur in one of three locations on the distal digit. They arise owing to a metaplastic or degenerative process. Preexisting osteoarthritis is common and may be an etiologic factor in patients with DMCs. A number of conservative and surgical treatments are available depending on the structures and locations involved. CONCLUSION: Studies with greater sample size and longer follow-up would enrich current knowledge of the benefits, recurrences, and complications for each treatment modality.
