How is ringworm diagnosed? my one year old has a circular rash that looks like it may either be eczema or ringworm.

Treatment: Most would treat and if it did not respond to the over the counter antifungal cream you could either see a dermatologist or try a steroid cream which would resolve the eczema.

Ringworm: Often, the diagnosis of ringworm is obvious from its location and appearance. Otherwise, skin scrapings for microscopic examination and a culture of the affected skin can establish the diagnosis of ringworm. If the diagnosis is unclear, a potassium hydroxide (koh) preparation of a skin scraping can be reviewed under the microscope to confirm the diagnosis of a fungal dermatophyte infection.
