Treatment of Relapsing HPV Diseases by Restored Function of Natural Killer Cells.

Human papillomavirus (HPV) infections underlie a wide spectrum of both benign and malignant epithelial diseases. In this report, we describe the case of a young man who had encephalitis caused by herpes simplex virus during adolescence and currently presented with multiple recurrent skin and mucosal lesions caused by HPV. The patient was found to have a pathogenic germline mutation in the X-linked interleukin-2 receptor subunit gamma gene (IL2RG), which was somatically reverted in T cells but not in natural killer (NK) cells. Allogeneic hematopoietic-cell transplantation led to restoration of NK cytotoxicity, with normalization of the skin microbiome and persistent remission of all HPV-related diseases. NK cytotoxicity appears to play a role in containing HPV colonization and the ensuing HPV-related hyperplastic or dysplastic lesions.

Familial linear scleroderma (en coup de sabre) responsive to antimalarials and narrowband ultraviolet B therapy.

A 32-year-old woman and her 35-year-old sister presented with plaques of scleroderma en coup de sabre. The younger sister's disease was more severe and preceded the older sister's by 10 years. This is the second reported case of familial en coup de sabre, and the first case of horizontal transmission. Treatment of the younger sister with antimalarials and narrow-band ultraviolet B (NB-UVB) phototherapy slowed disease progression and reversed hair loss. The observation that NB-UVB was effective in this case of linear scleroderma suggests that it may be indicated as a therapy for cutaneous scleroderma.
