OBJECTIVE Pseudoxanthoma elasticum is an inherited metabolic disorder resulting from ABCC6 gene mutations. It is characterized by progressive calcification and fragmentation of elastic fibers in the skin, retina, and the arterial wall. Despite calcium accumulation in the arteries of patients with pseudoxanthoma elasticum, functional consequences remain(More)
BACKGROUND Pseudoxanthoma elasticum (PXE), caused by mutations in the ABCC6 gene, is a rare multiorgan disease characterized by the mineralization and fragmentation of elastic fibers in connective tissue. Cardiac complications reportedly associated with PXE are mainly based on case reports. METHODS A cohort of 67 PXE patients was prospectively assessed.(More)
OBJECTIVES Pseudoxanthoma elasticum (PXE) is an inherited metabolic disease characterized by elastic fiber fragmentation and calcification in the cutaneous, ophthalmologic, and vascular tissues. Cardiovascular manifestations such as peripheral arterial disease (PAD) are frequent in PXE. Because of the changes in the elastic properties and medial(More)
BACKGROUND Ipilimumab is a monoclonal antibody targeting cytotoxic T-lymphocyte antigen 4 (CTLA-4) that allows increased survival and, occasionally, complete remission, in the treatment of metastatic melanoma. The most frequent adverse effects are attributed to dysimmunity. We report the case of a female patient who developed orbital myositis during(More)
BACKGROUND Lichen sclerosus et atrophicus rarely affects the feet or hands and in this case, it is generally part of widespread cutaneous involvement. We report a case of lichen sclerosus et atrophicus involving only the extremities and the vulvar and perigenital area. PATIENTS AND METHODS A 56-year-old woman presented with lesions of the hands and feet,(More)
BACKGROUND Cutaneous angiosarcoma is a rare aggressive vascular neoplasm with a poor prognosis, seen chiefly in elderly subjects and usually on the scalp or face. The present case is original because of its localization on the leg without any chronic lymphoedema and because of the long survival period. The treatment modalities are discussed. CASE REPORT(More)
Leukonychia is an ungueal discoloration or dyschromia. The hereditary form is rare. In the observations reported in the literature, leukonychia was total or sub-total, and was sometimes associated to other various symptoms. We report an original observation of hereditary leukonychia totalis in a father and two of his children, associated with(More)
Background.  Buruli ulcer, caused by Mycobacterium ulcerans, is a necrotizing skin disease leading to extensive cutaneous and subcutaneous destruction and functional limitations. Spontaneous healing in the absence of medical treatment occurs in rare cases, but this has not been well described in the literature. Methods.  In a retrospective case study in an(More)
BACKGROUND In most patients pseudoxanthoma elasticum (PXE) manifests with yellowish cutaneous papules and dermal elastorrhexis on skin biopsy. In a small number of cases there are no skin manifestations on clinical examination, and establishing a diagnosis of PXE in such patients is challenging. High-frequency ultrasonography (HFUS) may be of use in(More)
