Mask phenomenon: postemesis facial purpura.

A bizarre form of purpura seen on the face and neck after vigorous vomiting is described. Physicians should be familiar with this form of purpura since patients are very concerned about the mask that appears suddenly. Recovery is spontaneous, and no treatment is needed.

Norwegian-type scabies mimicking contact dermatitis in an immunosuppressed patient.

Patients taking immunosuppressive drugs are susceptible to various forms of infection, including dermatologic disease. Recently, atypical manifestations of scabies have been reported in such patients. In the case reported here, a 26-year-old woman who had had a renal transplant and was taking immunosuppressive drugs had a pruritic rash on the back that closely resembled contact dermatitis. However, skin scrapings from the involved areas and punch biopsy specimen of the back showed live scabies mites. The pruritus was relieved and the skin lesions disappeared within ten days of treatment with scabicides. We believe that current widespread use of immunosuppressive agents may result in more cases of atypical forms of scabies. Therefore, physicians who deal with immunosuppressed patients should be aware of this possibility.

Cowden's disease in three siblings: electron-microscope and immunological studies.

Cowden's disease was diagnosed in three siblings (two sisters and a brother) in a Jewish Israeli family of Yemenite origin. The typical mucocutaneous lesions of the disease were present in all three cases. There were hamartomas involving other body systems, including euthyroid multinodular goiter (in all 3 cases), gastrointestinal polyposis (in 2 cases) and hemangioma (in one case). Developmental anomalies were found in all 3 cases. Histological examination of mucocutaneous lesions was in accordance with previous descriptions, including the findings compatible with trichilemmoma observed in cutaneous facial papules. Extensive electron-microscope studies of these facial lesions yielded no evidence of viral particles. Immunological studies, carried out mainly in two cases, revealed a decrease in complement level in the serum and impairment of T cell function.

Mycosis fungoides-like lesions associated with phenytoin therapy.

An 83-year-old woman developed generalized lymph node hyperplasia together with mycosis fungoides-like skin lesions 11 months after institution of anticonvulsant therapy with phenytoin. The clinicopathological changes disappeared completely three weeks after cessation of therapy. This circumstantial evidence together with the known data on the association of phenytoin with lymphoproliferative disorders suggest that it was the phenytoin that was responsible for the patient's condition. This case had features similar to those associated with the pseudo-mycosis fungoides syndrome except that the cutaneous lesions consisted of two localized erythematous plaques, with no generalized exfoliative erythrodermic dermatitis. Nonetheless, we believe that the use of the term pseudo-mycosis fungoides for this and similar cases would be appropriate.

Bowel bypass arthritis dermatitis syndrome: a histological and electron microscopical study.

A case of dermal vasculitis with arthralgia after intestinal bypass surgery is reported. A 36-year-old woman developed arthralgia and skin rash, 1 year after an ileo-jejunal bypass operation was performed for overweight (130 kg). Skin biopsy showed leucocytoclastic vasculitis in the dermis. E.M. study showed clumps of platelets around small dermis blood vessels, and polymorphous perivascular infiltration. The symptoms subsided after tetracycline treatment.

Oriental hornet venom enhances wound healing and repair in rat skin, possibly through its collagenolytic activity.

Oriental hornet (Vespa orientalis) venom sac extract (VSE) was topically applied to experimental wounds produced on the back skin of rats in order to observe histologically its effect on the healing process. In other studies the collagenolytic effect of VSE was investigated. The results clearly indicated that application of VSE enhanced the process of wound healing. Two weeks after wound induction a thick epidermis and maturation of the dermal connective tissue were seen in the experimental animals, whereas in the controls the dermis was thin and still showed granulation tissue, and the epidermis was thin. Incubation of VSE with purified neutral salt-soluble collagen (NSSC) labeled by reduction with [3H]NaBH4 brought about degradation of the substrate. It is assumed that VSE enhances the process of wound healing in the skin, probably due to its collagenolytic effect.

Bromoderma caused by carbromalhydroxyzine hydrochloride.

A patient is described who developed a pyoderma-gangrenosum-like ulcer of the leg and acneiform eruption on the face following intake of carbromalhydroxyzine hydrochloride (Dormax). Serum levels of bromide were found to have risen to 105 mg%. There was a return to normal levels of serum bromide and regression of the skin lesions after one week of treatment with natrium chloride and erythromycin. The importance of increasing awareness of the potential hazards of bromide administration is stressed.

Sebaceous glands changes following topical application of citral.

The long-lasting effect of a flavour cosmetic constituent on male rat skin was studied. Topical daily application of citral (15.4%) solution for 3 months produced an increase in the number of sebaceous gland lobules and hyperplasia of sebaceous cells in each gland. It is suggested that the mechanism of this hyperplasia might be activation of the testosterone 5 alpha-reductase which induces the formation of dihydrotestosterone, the mediator of sebaceous gland activity.
