Invasive dermatophytosis with lymph node involvement in an immunocompetent patient.

A 23-year-old man presented with annular and arcuate, hyperpigmented, itchy, scaly plaques over the trunk and lower extremities for 5 years progressing to verrucous papules and nodules for the last 1.5 years. He also had nontender, inguinal and axillary lymphadenopathy. Skin and lymph node biopsies showed granulomatous inflammation and special stains demonstrated long septate hyphae. Tissue cultures grew Trichophyton verrucosum. The patient was treated with itraconazole 100 mg twice daily for 8 months, resulting in complete clearance of the lesions.
