Nail apparatus melanoma: A comparative, clinicoprognostic study of the initial clinical and morphological characteristics of 49 patients - 15/07/15
Abstract |
Background |
Although nail apparatus melanoma has been widely evaluated, only limited data are available concerning its clinical features, which depend on its initial clinical morphology, broadly defined as a melanonychia or nonmelanonychia lesion.
Objective |
We sought to determine heterogeneity on the basis of the initial clinical morphology of nail apparatus melanoma.
Methods |
We searched the Asan Medical Center database for cases of nail apparatus melanoma that were confirmed by skin biopsy specimen. Patients were classified with either nail apparatus melanoma that began as melanonychia (group A) or nail apparatus melanoma that began as nonmelanonychia lesions (group B).
Results |
We identified 49 patients with nail apparatus melanoma. Of these, 29 and 20 patients were included in groups A or B, respectively. The prediagnosis duration was significantly longer in group A. At the time of diagnosis, advanced stage and deeper Breslow thickness were noted in group B. The median overall survival period of the whole cohort was 93.0 months, and the 5-year overall survival was 67%. Patients in group A demonstrated better survival outcomes.
Limitations |
This study is a retrospective, single-center design.
Conclusion |
Nail apparatus melanoma demonstrates different clinical features and survival outcomes depending on whether the lesion begins as melanonychia or nonmelanonychia.
