, typically characterized by symmetrical, nonblanching, purpuric, telangiectatic, and atrophic patches with a predilection for the lower extremities and buttocks.
Plaques are usually 1-3 cm in diameter and annular with punctate telangiectasias and cayenne pepper petechiae in the border. The annular patches may form concentric rings. It is most commonly seen in children and young females.
The etiology of Majocchi’s disease is largely unknown and idiopathic.
Triggers are not always detected but may be associated with viral infections, chronic comorbidities, and medications. Levofloxacin and isotretinoin have been described in as reports as causing PATM. Other medications reported to cause PPD include sedatives, stimulants, antibiotics, NSAIDS, and cardiovascular drugs.
Diagnosis of PATM is clinical and histopathologic. Direct immunofluorescence (DIF) may show fibrinogen, IgM, and/or C3 deposition in superficial dermal vessels. Histopathologic findings show lymphocytic infiltrate involving the superficial small vessels, extravasated red blood cells, and hemosiderin-laden macrophages.
There is no consensus regarding treatment with variable responses to proposed treatment based on reports and case studies. The first line of treatment is topical corticosteroids and compression hose. Additional treatments, including narrowband UVB phototherapy (NBUVB), griseofulvin, pentoxifylline, cyclosporine, colchicine, rutoside with ascorbic acid, and methotrexate, have been used with varying success.
In this patient, a punch biopsy was performed, which revealed lymphocytes and extravasated erythrocytes and siderophages in the dermis. She was treated with topical steroids with improvement. She started NBUVB, a short course of griseofulvin, and vitamin C supplements.
