Discussion: This 17 yo girl has suffered with what appears to be tinea aminatacea for almost a decade. It appears unlikely that this is psoriasis. Tinea capitis has been ruled out by culture. Her bacterial culture showed 3+ S. aureus but I suspect this is a secondary invader as she did not improve with cewplanexin. Since the fungal culture was negative and these approaches were not helpful, I may recommend isotretinoin. The use of this has been reported for T. aminatacea only and in a Korean case report. The other question I have is whether a scalp biopsy may be helpful.
