Hailey-Hailey disease successfully treated with photodynamic therapy: Case report.

Hailey-Hailey disease (HHD) is a rare genetic benign condition resulting in blisters predominantly on the skin folds. The inheritance is autosomal dominant with complete penetrance, but a variable expressivity in affected family members. It can be triggered by a vast variety of factors such as sweating, weight gain, infection, trauma, pregnancy, and ultraviolet radiation, but the major cause of the disease is a mutation in the ATP2C1 gene.

A rare case of Buschke-Löwenstein tumor in HPVnegative patient.

Buschke-Löwenstein tumor is known to manifest not only in sexually active people and adolescents exposed to violence or drugs, but also in people who do not have any predisposing factors or bad habits. Several studies have shown that in the majority of children with anogenital warts, HPV can be transmitted asexually by hetero- inoculation or through infected objects. To our knowledge, there are currently few reports on BLT in HPV-negative patients in the literature.
