Background: Acquired ungual fibrokeratomas are uncommon fibrous tissue tumors located in the ungual area. Though there are many reports of this entity, only some reports have reviewed the clinical features of the tumor. Aims: The aim of this study was to clarify the clinical characteristics of acquired ungual fibrokeratomas. Methods: We reviewed twenty patients who were treated surgically at our clinic from 2003 to 2014 for acquired ungual fibrokeratomas confirmed on histopathological examination. Our study was conducted by retrospective analysis of charts, clinical pictures and patient records. Cases of tuberous sclerosis were not included. Results: Acquired ungual fibrokeratomas occurred on toenails in 16 (80%) patients and on fingernails in 4 (20%) patients. Periungual lesions were noted in 15 (75%) patients followed by intraungual lesions in 4 (20%) patients and subungual lesions in 1 (5%) patient. A longitudinal groove was observed in 80% of patients. Surgical resection was performed in all cases for both medical and cosmetic reasons. After excision, recurrence occurred in three cases. Limitations: This was a retrospective study of a limited number of patients. Conclusions: Acquired ungual fibrokeratomas occurred more commonly on toenails than on fingernails and were located in the periungual area in most patients. A longitudinal groove in the nail plate was a frequent finding. Surgical resection led to medical and cosmetic improvement with a recurrence in 3 (15%) patients.
