Noteworthy, the diagnosis of mycetoma in non-endemic or low endemic areas as Europe and North Africa is challenging.

This type of skin cancer starts in basal cells — a cell type within the skin that produces new skin cells as the old ones die off, according to the Mayo Clinic. Symptoms can range from looking ...
Computer-assisted diagnosis devices have been developed that analyze images from a dermatoscope or spectroscopy and can be used by a diagnostician to aid in the detection of skin cancer. CAD systems have been found to be highly sensitive in the detection of melanoma, but have a high false-positive rate.
Signs and symptoms range widely. [3] There is usually a rash with superficial infection. [2] Fungal infection within the skin or under the skin may present with a lump and skin changes.
