The literature reports an annual incidence of 5,900 cases of anal cancer in the developed countries. These involve three different anatomic zones: carcinoma of the anal canal, perianal carcinoma (formerly known as carcinoma of the anal margin, located at a distance of less than 5 cm from the anal margin), and carcinoma of the perianal skin (at a distance greater than 5 cm from the anal margin). Basal cell carcinoma of the perianal region is an uncommon tumor (0.27% of all diagnosed basal cell carcinomas) that in the majority of cases is treated by resection with disease-free margins. It must be differentiated from the basaloid and epidermoid variants of carcinoma, given that it has good outcome and its spread potential is practically null. 相似文献

Penicilliosis is an opportunistic infection in HIV-infected and other immunocompromised patients mostly in Southeast Asia, Southern China, Hong Kong, and Taiwan, with respiratory manifestations in about one-third of patients. We report the case of a 26-year-old non-HIV immunocompromised patient presenting with an airway obstruction caused by penicilliosis, together with a review of the literature of this rare condition. 相似文献

Microscopic polyangiitis (MPA) is a systemic disease included in the Chapel Hill 2012 Classification as necrotizing vasculitis affecting capillaries, venules and arterioles. It usually expresses antineutrophil cytoplasmic antibodies (ANCA) and has a perinuclear immunofluorescence pattern and correlation with anti-myeloperoxidase (MPO) antibodies. Capillaritis with alveolar hemorrhage is the most common manifestation of lung disease. Interstitial lung disease (ILD) is uncommon, with usual interstitial pneumonia being the predominant pattern. However, other patterns such as organizing pneumonia have been described. No guidelines exist for treating patients with ILD and, currently, ANCA-associated vasculitis (AAV) is managed along the lines of small vessel vasculitis. The prognosis with this association is uncertain, with possibilities of relapse and a fatal outcome. We present a case in which ILD was the first manifestation of MPA, without alveolar hemorrhage, with subsequent renal involvement and, in which, the established treatment produced a significant clinical improvement. 相似文献

Neurological involvement in Behçet's disease is rare, especially at the onset. It can present in the form of parenchymal changes or as damage to the vascular structures in its nonparenchymal form. The coexistence of both kinds of manifestations in the same patient is exceptional. We report the case of a 32-year-old patient with a history of deep venous thrombosis, who was being treated for holocranial headache, apathy, and oral and genital ulcers. Brain magnetic resonance imaging showed hyperintense lesions in the basal ganglia and white matter, and the vascular study evidenced venous thrombosis of the left transverse sinus. After confirming the diagnosis of Behçet's disease with parenchymal and nonparenchymal cerebral involvement, immunosuppressive and corticosteroid therapy was started, resulting in the remission of the symptoms. 相似文献

Chikungunya virus infection (CHIKV) is associated with joint involvement in half of the cases. This can lead to erosive arthritis which, given the high intervariability of clinical and serological presentations, and the probable role of genetic conditioning in the severity and chronification of the condition, represents a great diagnostic and therapeutic challenge. There is an important lack of scientific evidence that would enable us to characterize the variability of the patient and choose the most appropriate approach. 相似文献

Pica is an individual entity in the patient with chronic kidney disease (CKD), which phenomenon has not been widely studied despite the high reported prevalence. Moreover, pica complications (anemia, altered electrolytes, poor absorption of micro and macronutrients and malnutrition) could be exacerbated in CKD and limit the quality of renal replacement therapy.The intake of non-caloric and non-nutritional substances could be harmful and cause effects on satiety and metabolic / electrolyte imbalance and modify the biocompatibility of micronutrients, toxins and pathogens worsening health status.In daily practice, pica could be under-reported because patient's shame to recognize it, or fear that such behavior influences their treatment. Additionally, clinicians who not investigate the presence of pica or its complications contribute to the lack of information about the magnitude and relevance of this problem in CKD. 相似文献

BackgroundPodocyte infolding glomerulopathy (PIG) is a condition of uncertain origin, frequently associated with autoimmune diseases. Its specific treatment and clinical course are unknown.It is characterised by thickening of the capillary walls due to the presence of non-argyrophilic intramembranous bubbles similar to those found in membranous glomerulopathy, but without electron-dense deposits of immune complexes in the ultrastructure, where translucent microspheres generated by invagination of the podocyte cytoplasm into the basement membranes are observed.ObjectivesGenerally reported in young females patients. To date, few cases in Asian patients have been reported. Our case is the first to be reported in a Latin American Caucasian patient.MethodsA 38-year-old woman with SLE. In 2014 she presented with nephrotic syndrome empirically treated with corticosteroids (CO) and intravenous cyclophosphamide with good response. She had a relapse in April 2015 with normal renal function and no extrarenal lupus activity, so she was referred to our hospital to be biopsied.ResultsThe biopsy reported focal segmental glomerular sclerosis without deposits of immune complexes in the immunofluorescence. However, methenamine silver staining revealed clear spaces in the capillary walls accompanied by marked podocyte alterations. On electron microscope study, numerous aggregates of microvesicular and cylindrical ultrastructures bound to the membranes were observed, without evidence of dense deposits, and diffuse effacement of pedicel foot processes, confirming the suspected diagnosis.ConclusionsThis is the first reported case of what can be considered a new pathological glomerular entity in a Latin American Caucasian patient, whose clinical course and therapy are still unknown. 相似文献
