Treatment of verruca plana with 5% 5-fluorouracil ointment

11 patients with verruca plana were treated with 5% 5-Fluorouracil ointment as a twice daily topical application with open dressing. The patients were chosen among those who failed to be cured with avrious topical agents such as salicylic acid, vitamin A acid and dinitrochlorobenzene (DNCB), or even with carbon dioxide cryotherapy, oral administration of methotrexate and intramuscular injection of sodium cacodylate. In 9 patients, all the treated warts completely disappeared within 3--5 weeks. 2 of these patients had recurrence after 3 weeks and 2 months, respectively. In 2 patients, some lesions disppeared while others failed to be healed. The major clinical adverse reactions were hyperpigmentation (8 cases), erythema (5 cases) and erosion (5 cases).

Eruptive vellus hair cyst. Clinical and histologic findings

This is, to our knowledge, the second report of eruptive vellus hair cysts. The lesions, which occurred in an 18-year-old woman, consisted of 35 to 40 brownish-black, 1- to 4-mm papules on the anterior aspect of the chest. Histologically, the lesions consisted of small cysts in the middle dermis that contained laminated and amorphous keratinous material and vellus hairs. The cyst wall consisted of several layers of squamous epithelium with a rudimentary follicle attached to its outer aspect. The lesions regressed spontaneously after ten months. The pathogenesis is obscure but the condition appears to be a new distinctive entity.
