Supposing a patient has Tinea Capitis (Ringworm of the scalp) what will you see under a magnifying glass?


Probably nothing diagnostic would be seen using a handheld magnifying lens. Preferably one would use a microscope but that also has limitations.

Microscopic examination of the infected hairs may provide immediate confirmation of the diagnosis of ringworm and establishes whether the fungus is small-spore or large-spore ectothrix or endothrix.


  • +1: Maybe point out the difference between a magnifying glass (max. 2x magnification) and a microscope (max 1000x magnification, values taken from Wikipedia. Some handheld lenses could go up to 6x, but that’s no match...

You will see hyphae (which produce spores that appear as crusted plaque-likelesions on the scalp)
