Lichen planus.

Lichen planus, a papulosquamous disease, in its classical presentation is characterized by pruritic violaceous papules most commonly on the extremities of middle-aged adults. It may or may not be accompanied by oral and genital mucous membrane involvement. Its course is generally self-limited for a period of several months to years, but it may last indefinitely. There are many clinical variants described, ranging from lichenoid drug eruptions to association with other diseases such as diabetes mellitus, autoimmune disease, and the graft-versus-host reaction. The relationship of these, if any, to classical lichen planus is questionable. Multiple therapeutic options exist including corticosteroids, retinoids, griseofulvin, PUVA, and cyclosporine.

Multiple cutaneous granular cell tumors and neurofibromatosis in childhood. A case report and review of the literature.

Multiple cutaneous granular cell tumors have been previously reported in only 26 children or adolescents. An association of these tumors with neurofibromatosis has never been reported previously. We describe a 12-year-old black girl with multiple cutaneous granular cell tumors and neurofibromatosis. Although the histogenesis of these tumors is not completely clear, the findings of ultrastructural and immunohistochemical evaluation of our patient's tumors and the associated neurofibromatosis support a neural crest origin for granular cell tumors.

Contact immunotherapy of resistant warts.

Contact immunotherapy has been proved effective in the treatment of resistant warts. This report chronicles our experience with a new contact immunotherapy agent, diphenylcyclopropenone. We have achieved a cure rate of 62% in 45 patients with resistant warts of all types who came to our general dermatology clinic. Cure rates may be lower in patients who have experienced multiple treatment failures. The majority of cures were obtained within 3 to 4 months. Although it appears somewhat less effective than published reports of dinitrochlorobenzene contact immunotherapy, diphenylcyclopropenone contact immunotherapy is an effective treatment for resistant warts and avoids any potential problems from mutagenicity.

Unilateral atrophoderma of Pasini and Pierini.

Atrophoderma of Pasini and Pierini usually appears as isolated, round to oval depressed areas of otherwise normal-appearing skin. The clinical appearance has been likened to "footprints in the snow" or depressions with "cliff drop" borders. The condition is of unknown cause and most commonly occurs on the back, but it is occasionally seen elsewhere on the body. A literature search revealed only one previous report of unilateral atrophoderma of Pasini and Pierini.

X-ray epilation for the treatment of trichiasis.

.richiasis is a complication of many different disorders of the eyelids. Treatment is difficult and painful when conventional methods of plucking, surgical excision, electrolysis, or cryotherapy are employed. Since superficial x-ray therapy for the treatment of eyelid skin cancers causes permanent loss of the eyelashes in the irradiated field, we attempted to exploit this observation for the treatment of trichiasis. A rabbit model was used to determine the minimum permanent epilating dose. The dose was found to be approximately 4,000 rad of superficial radiation along with the following factors: 110 kV, 10 mamp, a target skin distance of 20 cm, a half-value layer of 1.0 mm of aluminum, and no filter. The dosage schedule used was 300 rad given three times per week. Two patients with severe scarring trichiasis were treated with the same factors and a total dose of 4,000 rad; excellent results were achieved. We believe that x-ray therapy is an easy, safe, and painless method for the management and cure of chronic trichiasis.

Localized acquired cutaneous pseudoxanthoma elasticum.

Localized acquired cutaneous pseudoxanthoma elasticum is a new designation proposed for a nonheritable form of pseudoxanthoma elasticum (PXE), lacking the retinal and vascular stigmata associated with the inherited form of the disorder, but having skin lesions that are clinically, histologically, and ultrastructurally similar to those seen in the inherited type. A patient is presented with skin lesions confined to the chest and abdomen. Similar cases from the literature, some apparently idiopathic in multiparous black females and others with histories of cutaneous exposures to calcium salts, are grouped together as examples of the acquired form of PXE.

Acrodermatitis enteropathica.

Acrodermatisis enteropathical has had a remarkable hist orical course beginning only 35 years ago, first passing through a period of empiric management with the 8-hydroxyquinoline drugs and culminating with the discovery of a biochemical effect in zinc absorption. This accomplishment has not only resulted in the cure of a serious and often fatal disease, but has opened the way to an understanding of the vital role played by the trace element zinc in many previously unrecognized areas of human physiology.

Neuropsychological findings with pseudoxanthoma elasticum.

It has been reported that the disease pseudoxanthoma elasticum (PXE) is associated with a high incidence of neurologic and psychiatric symptoms, which are possibly due to cerebrovascular ischemia. These reports are based mainly upon clinical observations made without reference to control group data. We have compared the results of 27 PXE patients with results of a control group on a battery of objective neuropsychological and personality tests. The PXE group showed only very mild deficits on extensive neuropsychological testing, a finding which argues against any marked involvement of cerebral vessels in these patients. Similarly, the personality test results did not reveal significant psychiatric disturbances which could be attributed to PXE. Possible reasons for the descrepancy with previous reports include the subjective data and much older PXE patients on which those reports are based. The need for systematic neuropsychological research with older PXE patients and control groups is suggested.
