Successful treatment of acquired reactive perforating collagenosis with itraconazole

BACKGROUND: Acquired reactive perforating collagenosis (ARPC) is a rare form of transepithelial elimination in which altered collagen is extruded through the epidermis. CASE PRESENTATION: A 23-year-old male presented with cup-like ulcerated lesions on his limbs since 3 months. A series of serological and immunological tests showed no abnormalities. A diagnosis of ARPC was based on skin biopsy findings. The patient was cured using treatment with itraconazole for 8 weeks, in the absence of a fungal infection. CONCLUSIONS: The anti-inflammatory and anti-angiogenic effects of itraconazole can have good therapeutic benefits for ARPC.
