Severe Esophageal Lichen Planus Treated With Tofacitinib.

Lichen planus is a chronic inflammatory immune disorder that most commonly affects the skin and mucous membranes. Esophageal lichen planus (ELP) is a frequently misdiagnosed and poorly understood form of lichen planus that can be asymptomatic or present with dysphagia and odynophagia caused by the formation of erosions and strictures in the esophagus. These strictures often reduce a patient's quality of life and may lead to emaciation in more severe cases.

Human Polyomavirus 9-An Emerging Cutaneous and Pulmonary Pathogen in Solid Organ Transplant Recipients.

Importance: We describe the first report to our knowledge of cutaneous and systemic pathogenicity of human polyomavirus 9 in solid organ transplant recipients.

Objective: Three solid organ transplant recipients developed a widespread, progressive, violaceous, and hyperkeratotic skin eruption. All died from pulmonary and multiorgan failure around 1 year from onset of the rash.
