Pemphigus is a rare autoimmune disease during pregnancy. Among the different pemphigus types, pemphigus foliaceus (PF) is even rarer than pemphigus vulgaris. We present a case of PF in a 36-year-old female patient who presented with PF onset during pregnancy in the form of a disseminated, erythematosquamous rash. A diagnosis was made on the basis of histologic, immunofluorescence, and enzyme-linked immunosorbent assay results. A complete remission was recorded a month after steroid treatment initiation. The patient delivered a premature (33 weeks) but otherwise healthy baby girl. Only three cases of PF have been reported in two retrospective studies found in the English-language bibliography. Although pemphigus during pregnancy is a rare disease and treatment guidelines have not yet been elucidated, the management of these cases is individually evaluated. In all cases, the primary goal should be the control of the maternal disease along with the safety of the fetus.
Regression of congenital nevi is usually associated with loss of pigment or halo formation. In rare cases, regression is characterized by sclerosis and hair loss. We describe a rare case of a sclerotic hypopigmented large congenital melanocytic nevus in which a localized scleroderma-like reaction process of regression seemed to have started in utero and progressed throughout early childhood.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
