Introduction: Whipple's disease is a rare, chronic, systemic disease caused by the actinomycete Tropheryma whipplei. Clinical manifestations vary widely depending on the affected system, the most common being the digestive tract. Case Presentation: The authors report the case of a 52-year-old man with malabsorption syndrome, diarrhea, marked weight loss, melanoderma, and visual and proprioception disorders. Periodic acid-Schiff staining of a proximal small bowel biopsy and peripheral-blood PCR identification of T. whipplei confirmed the disease. The patient was initially treated with intravenous ceftriaxone, followed by oral trimethoprim/sulfamethoxazole with significant clinical improvement. Conclusions: This case is reported due to its rarity and the diagnostic challenge it presents. Although uncommon, Whipple's disease should be considered as a differential diagnosis of malabsorption syndrome due to its systemic impact and possible treatment with targeted antibiotic therapy.sua raridade e pelo desafio diagnóstico. Apesar de incomum deve ser considerada como diagnóstico diferencial do síndrome de má absorção atendendo ao seu impacto sistémico e ao possível tratamento com antibioterapia dirigida.
<b><i>Introduction:</i></b> Immunoglobulin light chain-associated amyloidosis results from extracellular tissue deposition of fibril-forming monoclonal immunoglobulin light chains, secreted by a clone of plasma cells. Although the liver is often involved histologically, most cases are clinically asymptomatic, and severe intrahepatic cholestasis as the primary manifestation of the disease is rare. <b><i>Clinical Case:</i></b> We report an unusual case of primary amyloidosis in a 71-year-old man, presenting with rapidly progressive cholestasis, associated with hepatomegaly. There are a few reported cases in the literature of cholestasis and acute liver failure as the first manifestations of AL amyloidosis. <b><i>Conclusion:</i></b> Infiltrative diseases, such as amyloidosis, must be considered when a patient presents with cholestatic hepatitis. A liver biopsy is essential for the diagnosis of amyloidosis when liver test abnormalities dominate the initial clinical presentation. Liver involvement in patients with amyloidosis is often an indicator of poor prognosis.
Pancreatic cancer is the tumour related to higher rates of depression. Several papers have validated the association between pancreatic cancer and depression. It was noticed that in some cases the psychiatric symptoms precede the somatic ones. We present a case of a progressive and incapacitating diffuse abdominal pain, initially attributed to psychosomatic disorder. This hindered a timely correct diagnosis leading to a poor outcome. A pancreatic adenocarcinoma in an unresectable stage was confirmed by histopathology. The patient underwent chemotherapy.
IgG4-related disease is a recently recognized autoimmune systemic disorder that has been described in various organs. The disease is characterized histologically by a dense lymphoplasmacytic infiltrate with IgG4-positive cells, storiform fibrosis, obliterative phlebitis, and can be associated with space-occupying lesions. IgG4-related disease involving the upper gastrointestinal tract is rare. We report the case of a 30-year-old female patient with a long-standing history of severe dysphagia and odynophagia. Symptoms persisted despite anti-acid therapy, and control esophagogastroduodenoscopy revealed endoscopic images consistent with a nontransposable stenosis in the proximal esophagus. An underlying autoimmune process was suspected, and topical immunosuppressants were tried to control her disease. The patient maintained disabling dysphagia secondary to chronic esophageal strictures. A diagnosis of probable IgG4-related disease was made after esophageal biopsies. Treatment attempts with topical corticosteroids was not associated with a significant improvement of the symptoms of dysphagia and odynophagia, possibly because of the chronic nature of the disease associated with a high fibrotic component. This report describes a case of IgG4-related esophageal disease presenting as chronic esophagitis with strictures. We also briefly review the main histopathological features and treatment options in IgG4-related disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
