Leukemic vasculitis: an unusual manifestation of leukemia cutis.

Leukemia cutis is frequently observed as papules, nodules, and plaques, but unusual clinical manifestations rarely occur. We report a 64-year-old woman with acute myeloid leukemia M1 who presented with erythematous papules and vesiculobullous lesions limited to the arms, hands, and neck in addition to purpuric papules on the legs. Because of the symmetric distal involvement and vesiculobullous nature of the skin lesions, the differential diagnosis included erythema multiforme and vasculitis.

Erosive pustular dermatosis of the leg: an overlooked entity?

Background: Erosive pustular dermatosis is a distinctive clinical entity that has been described on either the scalp or legs.

The scalp is the most commonly encountered localization, whereas erosive pustular dermatosis of the leg has also been reported in several cases.

Is there a role for sulfasalazine in the treatment of alopecia areata?

Promising results have been published in the past with the use of sulfasalazine in alopecia areata. We also observed maintenance of hair growth in refractory alopecia areata patients who were treated with sulfasalazine in combination with oral corticosteroids for 2 to 6 months and sulfasalazine alone for 4 to 12 months while steroids were being tapered. We believe that, because of the small series reported herein, additional larger prospective studies should be conducted to validate these results.

Therapeutic potential of azithromycin in rosacea.

Background: Systemic antibiotics currently used in the treatment of rosacea are sometimes associated with uncomfortable side-effects. Therefore, a need for an effective agent with few side-effects and good patient compliance exists. Azithromycin, a macrolide antibiotic with prolonged mode of action, has recently been found to be an effective alternative in the treatment of inflammatory acne.
