Abstract
- BACKGROUND
In East Asia, the foot is the most common site of cutaneous melanoma. The purpose of this study was to investigate the differences between cutaneous melanoma of the foot and melanomas of other sites.
METHODS
We studied 52 patients who underwent surgical treatment for cutaneous melanoma of the foot from September 2000 to January 2015. Through a retrospective review of their medical records, we collected data relating to their sex, age, histopathological subtype, Clark level, tumor thickness, lymph node involvement, stage, and survival rate, and we compared these parameters to those of 61 patients treated for melanoma of other sites. Moreover, we analyzed the surgical procedures, complications, and mortality rates associated with cutaneous melanoma on various parts of the foot.
RESULTS
Melanoma of the foot differed from other melanomas only in the histopathological subtype. Other clinical features, including survival rate, did not differ significantly between the two groups heel was the most common site of melanoma of the foot (22 cases, 42.3%). The method of reconstruction varied depending on the region involved.
CONCLUSIONS
A comparison of melanoma of the foot to other melanomas showed that melanoma of the foot was associated with a significantly different distribution of histological subtypes. Consistent with previous findings, we found that the acral lentiginous subtype was the most common among melanomas of the foot. Furthermore, in contrast with previous studies, we did not find a worse prognosis or lower survival rate for melanoma of the foot in comparison with other melanomas.
