A 44-year-old woman presented with an eczematous, oozing eruption on her head, the back of her neck, and ears (Figure) that appeared one day after she had used a henna dye on her hair. She was aware of her allergy to permanent hair dyes, but her dermatologist approved of her use of natural dyes, such as henna. The dermatitis resolved within 1 week after she received an injection of combined betamethasone dipropionate 5 mg and betamethasone sodium phosphate 2 mg (Diprospan; Schering-Plough, Kenilworth, NJ).

The Blue Peel: how to do it less expensively and faster.

One well accepted and popular method worldwide for trichloroacetic acid peels is the Obagi Blue Peel technique (Obagi Medical Products, Long Beach, CA). The peel solution is prepared by mixing a fixed volume of 30% trichloroacetic acid with the commercially available Blue Peel base. The authors suggest modifications for performing the peeling faster and less expensively: 1) preparing a larger volume of peel solution from each tube of Blue Peel base; 2) using higher concentrations of peel solution to reduce the number of coats necessary for reaching the desired depth of peel; and 3) storing the solution, as there is no need to adhere to the manufacturer's instructions to prepare the solution immediately before conducting the peel procedure to ensure homogeneity of the solution. The prepared solution can be stored at least 1 year.

Telangiectasia macularis eruptiva perstans: unusual presentation and treatment.

A 41-year-old woman presented with a 2-month history of pruritus and a generalized dermatitis that developed initially on the head and spread to the trunk, legs, and buttocks. The pruritus caused extreme discomfort and was not relieved by antihistamines or topical steroid treatment. The patient denied flushing, syncope, and vomiting. Her medical history included asthma treated with salmeterol/fluticasone propionate inhaler, and status post silicone breast augmentation. Physical examination revealed a papular dermatitis on the trunk and extremities composed of lesions up to 0.5 cm in diameter, surrounded by excoriation marks (Figure 1). There was no hepatosplenomegaly or lymphadenopathy. Darier's sign was negative. Results of complete blood count, peripheral blood film examination, and liver function tests were all with normal limits. A biopsy specimen taken from a lesion and stained with hematoxylin-eosin showed telangiectasias, with an increased number of mast cells around blood vessels (Figure 2). Positive Giemsa (Figure 3) and c-kit stain (Figure 4) indicated an increased number of mast cells. Bone marrow aspiration and total body CT performed to rule out systemic involvement showed no pathology. Protein electrophoresis was normal. Serum tryptase and histamine were within normal limits, and 24-hour urine collection for histamine was normal. Narrow-band UV-B treatment was begun 3 times weekly, reduced to twice weekly after 2 months, and then stopped. The first few treatments resulted in significant relief of the pruritus and regression of lesions. After 3 months without treatment, the patient remained free of pruritus and lesions.
