Ans. A. Tinea corporis
- The clinical description given in question and the picture indicate towards the diagnosis of tinea incognito i.e. tinea infection altered by steroid use.
- Tinea corporis is dermatophytosis of the trunk, legs or arms, especially on glabous skin.
- It may have a variety of appearances.
- Most easily identifiable are the enlarging raised red rings with a central area of clearing (ringworm).
- The same appearances of ringworm may also occur on the scalp (tinea capitis), beard area (tinea barbae) or the groin (tinea cruris, known as jock itch or dhobi itch).
