Question

A 12-year-old boy presents to the clinic with several small, circular, erythematous lesions on his arm. The lesions appear raised but have a central area of clearing. His mother reports that his sister has several similar "spots" on her abdomen. What is the most likely diagnosis?

Answer 1

Answer:

Ringworm

Explanation:

This fungal sickness (tinea corporis) can be due to an infection of another person or animal near the patient. Several fungi species can produce this sickness like the athlete`s foot (tinea pedis), but when is present in another part of the body, has a different name.

The incubation period is around 2 weeks, because the spores of the fungus can spread and be contagious, also in this period, the fungus can eat from the   collagen of the infected skin and live with the water present in the skin.

The treatment is with some fungus pills.
