Pemphigus vulgaris (PV) is a chronic autoimmune blistering disease of the skin and mucous membranes. Most cases occur in adults; cases in children are rare. This report describes the clinical presentations and treatment responses of three children with PV, as confirmed according to histology and indirect immunofluorescence studies. In all three cases, oral prednisone used in conjunction with mycophenolate mofetil (MMF) resulted in complete clinical remission, during which all pharmacotherapy was successfully discontinued. Resolution of the skin and mucosal blistering tended to occur quickly with prednisone, and after initiation of treatment with MMF, discontinuation of all pharmacotherapy was achieved within a range of 10 to 30 months in the three patients. One patient experienced a recurrence of genital lesions 19 months after discontinuation of therapy, but the condition remitted within 2 weeks with topical corticosteroid therapy. At the time of this report, the duration of complete remission ranged from 6 to 19 months. In summary, combination therapy with prednisone and MMF for pediatric PV appears to be a safe and effective approach that is associated with durable remission.

We describe a case of group B streptococcal endocarditis in a 15-year-old girl after an elective abortion. There are only 6 reports of group B streptococcal endocarditis in older children. It is a well described but rare complication of surgical abortions, and tends to have an aggressive course.

Vascular malformations are comprised of localized abnormal vascular channels that are the result of errors in vascular development. Vascular malformations may cause significant morbidity from local invasion, functional compromise, pain, or associated hematologic abnormalities. Although clinical findings are useful for diagnosis, imaging is often necessary to confirm diagnosis, assess the extent of disease, and guide appropriate treatments. For patients with extensive or complex disease, a multidisciplinary approach is often the best approach to management.

Background Nonbullous neutrophilic dermatoses are seen infrequently in association with lupus erythematosus (LE). A recently described histopathologic variant of Sweet syndrome, to our knowledge, histiocytoid Sweet syndrome (HSS) has not been described in either pediatric or adult patients with LE. Observations We describe 2 pediatric patients with nonbullous histiocytoid neutrophilic dermatitis in the setting of LE. One case represents the initial presentation of subacute cutaneous LE, while the other case represents a manifestation of established systemic LE. Both cases demonstrate histopathologic findings of HSS. Conclusions We believe that the dermatosis observed in these 2 patients represents a nonbullous histiocytoid neutrophilic dermatosis that is best termed HSS. This entity may represent a distinct and important cutaneous manifestation of LE. Additional study is needed to further elucidate the relationship between neutrophilic dermatitis and LE.
