Dermoscopy assisting the diagnosis of mycetoma: case report and literature review

Abstract

Mycetomas are a chronic skin infection characterized by perilesional edema, formation of sinus tracts, and discharge of purulent or seropurulent exudate containing grains. This report aims to demonstrate the clinical diagnosis (by dermoscopy) of a skin lesion that initially bared no clinical features of a mycetoma.

Molecular identification of unusual Mycetoma agents isolated from patients in Venezuela

“…Sudan appears to have the highest number of cases per capita of any country in the world . Most cases of mycetoma occur in India, Mexico, Sudan and Venezuela, although there are reported cases in other countries such as Argentina, Brazil, Iran and Somalia . Sporadic cases have also been reported in countries with mild weather .…”

“…1,2 Most cases of mycetoma occur in India, Mexico, Sudan and Venezuela, [3][4][5] although there are reported cases in other countries such as Argentina, Brazil, Iran and Somalia. [6][7][8][9][10] Sporadic cases have also been reported in countries with mild weather. 11 In Venezuela few cases of mycetoma have been reported in the literature.…”

Acral manifestations of fungal infections

“…74,75 Mycetoma is clinically characterized by papules, nodules, perilesional edema, formation of sinus tracts, and discharge of purulent exudate containing grains (Figure 7). 76 In some publications, it has been reported that it occurs more frequently in men than in females. It is most commonly seen on the foot.…”

Detecting subclinical mycetoma's black grains using dermoscopy

“…Dermoscopy is an easy, quick, and noninvasive tool widely used in the diagnosis of skin tumors. Recently, its use extended to the field of infectious skin diseases . Dermoscopy is helpful in visualizing minute grains (Fig.…”
