A case of bilateral tinea manus and the frequency of the superficial fungal hand infection (1997-2016)

Dermatophytosis of the palm of the hands (tinea manus) tends to involve one hand. We encountered a case of bilateral tinea manus in a patient with type 1 diabetes mellitus and bilateral tinea pedis. A 57-year-old man presented for evaluation of hyperkeratotic lesions on both his palms and soles. Skin examination revealed hyperkeratotic scaly lesions on the palmar surfaces of his hands and plantar surfaces of his feet. Yellow discoloration and thickening were observed on both his nails. Fasting venous plasma glucose concentration and hemoglobin A1c levels were 332 mg/dL and 7.5%, respectively. Fungus cultures revealed white colonies with brown color on the reverse side in a 14-day incubation period. Trichophyton rubrum infection was identified using polymerase chain reaction with amplified internal transcribed spacer regions. He was treated with oral fluconazole (150 mg/week) and topical flutrimazole spray. In addition, we examined the frequency of 77 superficial fungal hand infections (age, sex, seasonal distributions and coexisting fungal infections) among patients who visited the dermatologic clinic of Chonbuk University Hospital between January 1997 and December 2016.
