Mucous membranepemphigoid in two half-sisters. The potential roles of autoantibodies to β4 integrin subunits and HLA-DQβ1*0301.

Background: Mucous membrane pemphigoid (MMP) is a subepithelial autoimmune mucocutaneous disease. It most frequently affects the oral mucosa, followed by ocular and nasal mucosa, nasopharyngeal, anogenital, skin, laryngeal and esophageal mucosa.

Main Observation: Two half-sisters developed mucous membrane pemphigoid at approximately the same age.

Vesicular eruption on the arm of an infant.

Cutaneous mucormycosis is an uncommon disease and occurs mainly in immunocompromised patients. We report an immunocompetent infant who developed primary cutaneous mucormycosis at an intravenous line site secured with an arm board and elastic bandage. The isolate was identified as the zygomycete, Rhizopus sp.
