Case report of individual with cutaneous immunodeficiency and novel 1p36 duplication.

Introduction: Crusted or Norwegian scabies is an infectious skin dermatopathology usually associated with an underlying immunodeficiency condition. It is caused when the mite Sarcoptes scabiei infects the skin, and the immune system is unable to control its spread, leading to a massive hyperinfestation with a simultaneous inflammatory and hyperkeratotic reaction. This is the first report of a novel 1p36 duplication associated with a recurrent infection of crusted scabies.

Langerhans Cell Hyperplasia From Molluscum Contagiosum.

Langerhans cell histiocytosis (LCH) carries a prognosis, which ranges from benign to potentially fatal. There is currently little framework to decipher metrics, which predict the benign versus aggressive nature of LCH. We wanted to determine whether molluscum contagiosum virus (MCV) DNA could be isolated from a cutaneous lesion, demonstrating Langerhans cell hyperplasia resembling LCH in a patient with both.
