AAFM Dermatology Boards Practice Exam - Prep and Study Guide

Tinea corporis is commonly known as ringworm, which is a fungal infection of the skin that presents with round, ring-shaped, red patches that are often itchy. The name "ringworm" derives from the characteristic ring-like appearance of the lesion, although it is caused by a fungal organism rather than a worm. This condition can affect various parts of the body but is classified under dermatophyte infections, which include other forms such as athlete’s foot and jock itch. Understanding tinea corporis and its typical presentation is essential for diagnosis and treatment in dermatological practice.

Other options do not accurately describe tinea corporis: jock itch refers specifically to a fungal infection in the groin area, scabies is a condition caused by mites, and psoriasis is an autoimmune skin disorder resulting in thick, scaly patches on the skin. Each of these has distinct causes and clinical features that differ from those of tinea corporis.
