Pyoderma gangrenosum is a rare, ulcerative, cutaneous condition. First described in 1930, the pathogenesis of pyoderma gangrenosum remains unknown, but it is probably related to a hyperergic reaction. There are various clinical and histological variants of this disorder. Pyoderma gangrenosum often occurs in association with a systemic disease such as(More)
Systemic immunodeficiency is known to facilitate the onset of opportunistic infections, tumours and immune disorders in any district of the body. There are clinical events, such as chronic lymphoedema, herpetic infections, vaccinations and heterogeneous physical injuries which can selectively damage and immunologically mark the cutaneous district they act(More)
BACKGROUND Dermoscopy used by experts has been demonstrated to improve the diagnostic accuracy for melanoma. However, little is known about the diagnostic validity of dermoscopy when used by nonexperts. OBJECTIVE To evaluate the diagnostic performance of nonexperts using a new 3-point checklist based on a simplified dermoscopic pattern analysis. METHODS(More)
Pemphigus includes a group of autoimmune bullous diseases with intraepithelial lesions involving the skin and Malpighian mucous membranes. Pemphigus vulgaris (PV), the most frequent and representative form of the group, is a prototypical organ-specific human autoimmune disorder with a poor prognosis in the absence of medical treatment. The pathomechanism of(More)
Lymphedema is the result of accumulation of protein-rich interstitial fluid (lymph stasis) caused by a failure of lymph drainage in the face of a normal capillary filtration. Whether the origin is congenital or acquired from infection, radiation, trauma, or surgery, chronic lymph stasis impairs local immune surveillance by disrupting trafficking of the(More)
Pemphigus, a prototypical organ-specific human autoimmune disease, may be associated with other immunity-related disorders, viral infections, and different types of tumors. Coexistence with immune diseases is fairly frequent and, for some of them (eg, myasthenia gravis, Basedow's disease, rheumatoid arthritis, or lupus erythematosus), common pathogenic(More)
The lipophilic yeast Malassezia furfur is a member of the cutaneous microbiota, also associated with several chronic diseases such as pityriasis versicolor, folliculitis, seborrhoeic dermatitis, and some forms of atopic dermatitis, psoriasis and confluent and reticulate papillomatosis. In this study we determined the immunomodulatory and invasive capacity(More)
BACKGROUND There have been reports suggesting the involvement of environmental factors in the disease process of pemphigus. Factors suggested include exposure to pesticides or certain drugs. OBJECTIVE To analyze the association of pemphigus with environmental exposure to various agents, including smoking, recreational and occupational insults, drugs, and(More)
BACKGROUND Captopril is an angiotensin-converting enzyme inhibitor with sulphydryl groups in its chemical structure. It is commonly used as an antihypertensive drug. The occurrence of pemphigus vulgaris has repeatedly been reported in patients receiving captopril. The capacity of captopril and pemphigus serum to induce acantholysis, in vivo or in vitro, has(More)
The term pemphigoids includes a group of autoimmune bullous diseases characterized by subepidermal blistering. Bullous pemphigoid (BP) is not only the most common disorder within the pemphigoid group, but also represents the most frequent autoimmune blistering disease in general. The onset and course of BP depend on a variable interaction between(More)
