Abstract
A 56-year-old female patient with a personal medical history of class III obesity and uncontrolled DM presented to the ambulatory clinic with a pruritic rash behind her knees. The rash was of 4 weeks duration and did not improve with topical application of nystatin powder. Examination revealed an erythematous patch in the intertriginous area behind the knees bilaterally, associated with mild desquamation and clear demarcation from the normal skin. No satellite lesions were noticed. (figure 1A) The patient was evaluated for an intertriginous skin rash. The differential diagnosis included intertrigo, fungal infection, psoriasis, and lichen planus. Wood’s lamp examination was performed, and a clear greenish fluorescence over the lesional area was observed (figure 1B). Given the clinical context, greenish fluorescence on Wood’s lamp indicated a dermatophyte infection. The patient was started on oral antifungal therapy and showed subsequent improvement in her skin rash upon a follow-up visit.
