While the presence of lesions is the denominator among patients with<unk> , the characteristics of the lesions differ. The five clinical presentations of lesions associated with<unk>  include: * "Pemphigus-like": Flaccid blister (discrete), crusts over the raw exuding skin lesions * "Pemphigoid-like": Tense blister(s) on brick red erythema * "Erythema multiforme-like": Severe polymorphic skin and/or mucous membrane lesions * "Graft-vs.-host disease-like": Widespread lichenoid eruption with severe mucous membrane involvement * "Lichen planus-like": Small red flat-topped scaly papules It is most common that mucous membrane lesions of the oral cavity are presented first. They can involve the oropharynx, nasopharynx, tongue, and vermilion (red portion) of the lips. They are also known to develop in the conjunctiva of the eye, anogenital (perineum) region, and esophagus. Cutaneous lesions tend to follow the onset of mucosal lesions. The blisters often erupt in waves, usually affecting the upper trunk, head, neck, and proximal extremities. Pemphigoid-like lesions are seen more often on the extremities. Lichenoid lesions are more common among children, presenting on the trunk and limbs, ranging from small red scaly papules to extensive violet to brown papules extending to the face and neck. Within the spectrum of lichenoid presentations are wounds that have features of erythema multiforme and graft-vs.-host disease. Scaly lesions on the palms of the hand and soles of the feet have been noted to coincide with the lichenoid lesions. Lesions of varying morphology may present simultaneously and transform from one type to another as the disease progresses.
