| Abstract: | The differential diagnosis of subungual tumours is often very difficult, since the same tumor located in another area looks entirely different. Former infections or traumata may further mask the tumour. Pain is usually not characteristic. Infection and the history of a trauma may further mask this tumour. Pain is usually not characteristic. both malignant and benign tumours may develop from all tissues present in the distal phalanx. Subungual melanomas are the most common malignant subungual tumours, whereas a variety of benign tumours occurs in the subungual region, the most characteristic of them is the glomus tumour. |
