Background Subungual exostosis ( SE ) and subungual osteochondroma ( SO ) are an uncommon, benign tumor of the distal phalanx. The purpose of this retrospective study was to evaluate clinical, demographical, and radiological features; treatment modalities; and follow‐up results in SE and SO cases. Methods Twenty‐five cases were confirmed histopathologically as SE or SO . At the time of admission, clinical data were obtained on the age and sex of the patient, duration of symptoms, presence of pain, previous diagnoses and treatments, concomitant systemic diseases, family history, lesional localization, clinical and radiological features of the lesion, surgical treatment methods, and duration of follow‐up. Results There were 14 patients in the SE group and 11 patients in the SO group. There was no statistically significant difference in gender, age, duration of symptoms, or pain between the two groups. Regarding the locations of the lesions, two (14.28%) were on the hands, 12 (85.72%) lesions were on the toes, 11 (91.67%) of which were on the great toe, and one (8.33%) was on the small toe of the left foot in the SE group. All the osteochondroma lesions were located on the toes. In five (45%) cases, the lesion was on the great toe. Two patients had residual lesions in the SE group. Recurrence occurred in one case in the SO group. Conclusions Clinically and histopathologically, SE and SO appear to be two different entities. When diagnosed correctly and treated appropriately, the lesions have good functional and cosmetic results, as well as a very low recurrence rate.
