Background |
Onychoheterotopia is an extremely rare condition in which the nail tissue grows outside the classic nail unit of the dorsal fingers and toes. It presents as either small outgrowths of a deviant nail or a complete double fingernail malformation. The histology of the onychoheterotopia matrix is oftentimes very similar to the normal nail matrix, although it plays a central role in diagnosis.
Objective |
We sought to review the current literature on the clinical and histologic aspects of onychoheterotopia.
Methods |
A literature search was performed to evaluate peer-reviewed articles on the topic.
Results |
Detailed reports have characterized many features of onychoheterotopia. The various etiology and treatment options are reviewed.
Limitations |
The study was limited to those articles in the English-language literature.
Conclusions |
In this article, we provide a review of the literature based on the current understanding of onychoheterotopia, its diagnosis, and its management.
