Dermatophyte infections are exceedingly rare in neonates, possibly due to the thin stratum corneum and high sebum content of neonatal skin. Only a handful of cases of tinea faciei have been reported in neonates, with the majority of reports occuring in India. Here, we report what to our knowledge is the earliest reported presentation of tinea faciei in the United States. We also provide a brief literature review of other reported cases of tinea faciei in neonates less than 30 days of age.  相似文献

A 65-year-old Japanese man was hospitalized because of acute hepatitis and severe cholestasis due to hepatitis E virus (HEV) infection combined with a drug reaction to a cold preparation. He died of disseminated intravascular coagulation and severe intestinal bleeding due to systemic cytomegalovirus reactivation following the development of severe eruptions with marked eosinophilia due to drug hypersensitivity to taurine and ursodeoxycholate preparations. The close interaction between viral infection or reactivation and drug hypersensitivity was considered as a pathophysiology in this case, which emphasizes the need for further study of the immunological mechanism of the interaction.  相似文献

We reported a case of photoleukomelanodermatitis (Kobori) type drug eruption due to afloqualone (Arofuto®). The patient was given afloqualone and imipramine hydrochloride (Chrytemin®) for cervical spondylosis from November of 1990. Edematous erythema with slight itching appeared on the sun-exposed areas in December of 1990. As drug eruption was suspected, drugs were ceased, and the cutaneous lesions almost disappeared but pigmentations and depigmentations developed in spots in sun-exposed areas in March of 1991. Photopatch and oral challenge tests were positive.  相似文献

A boy with skin eruptions resembling varicella and specific for Langerhans cell histiocytosis (LCH) is reported. At his initial visit when he was four months old, vesiculopustular lesions were present over the entire body; these had first appeared on the third day post partus. Histopathological, immunohistochemical, and electron microscopical examination confirmed the Langerhans cell phenotype and Birbeck granules in the responsible cells. He also had hydronephrosis, recurrent fever, and cutaneous bacterial infections. His parents refused further medical treatment and he died of diarrhea with cachexia about two years later. LCH may present diagnostic difficulties by manifesting as a skin eruption which resembles varicella.  相似文献

BACKGROUND: Steroid-induced rosacea-like eruption is characterized by facial rosacea-like dermatitis in patients that have been treated with topical steroids for relatively long periods. OBJECTIVE: To evaluate the efficacy and tolerability of 1% pimecrolimus topical cream for steroid-induced rosacea-like eruption. METHODS: In an open-label pilot study, 40 patients were enrolled and instructed to apply 1% pimecrolimus cream twice daily for 6 weeks. Patients were evaluated by a rosacea clinical score, investigator's global assessment, overall erythema severity, and tolerability at weeks 0, 2, and 6. RESULTS: In 35 patients, the rosacea clinical score decreased significantly from 16.0+/-4.3 at baseline to 8.1+/-3.3 at week 2 and 4.2+/-2.5 at week 6 (P<0.0001). Investigator's global assessment was 4.1+/-1.1 (baseline), then decreased to 1.4+/-0.8 (week 2) and 0.5+/-0.6 (week 6) (P<0.0001). By week 6, 48.6% of the patients were clear. Overall erythema severity was 2.4+/-0.7 (baseline), 0.9+/-0.4 (week 2), and 0.3+/-0.4 (week 6) (P<0.0001). Cutaneous adverse events (local burning, stinging, and itching) occurred in 17.5%. CONCLUSION: Pimecrolimus cream might be efficacious, safe, and well tolerated for steroid-induced rosacea-like eruption. The small sample size and open label nature of this study is its limitation. Further double-blind, vehicle-controlled studies are needed.  相似文献

We report a case of an 81-year-old woman in whom lichenoid eruptions and Sjögren-like sicca syndrome developed 45 days after cholecystectomy. During surgery, one unit (130 ml) of unirradiated packed red blood cells from a male donor was transfused. The lichenoid eruptions cleared up with exfoliation; however, sicca symptoms remained during the follow-up period of four years. Histological examinations of both skin and lip biopsy specimens were in agreement with those of graft-versus-host disease (GVHD). A Y-chromosomal body was identified in the lymphocytes in the skin lesion by staining with quinacrine dihydrochloride and in the lip lesion by a method with in situ hybridization. The findings suggest that this case demonstrated the manifestations of non-fatal transfusion-associated GVHD.  相似文献
