Kimura disease is a benign rare chronic inflammatory disorder of unknown aetiology. This disease is mainly endemic in Asia, although cases have also been reported in Europe and America. We describe a case in a 34-year-old Chinese man presenting with severe eosinophilia and multiple lymphadenopathy. Since our initial aim was to rule out the diagnosis of lymphoma, and given the limitations of our laboratory, we decided to perform an excision of one of the cervical lymph nodes. The histological diagnosis was consistent with Kimura disease. We review the epidemiology, the aetiology and clinical features of this entity.
Unknown primary tumour refers to a group of cancers for which the anatomical site of origin remains occult after detailed investigations. Thanks to sophisticated imaging, immunohistochemical testing and molecular-profiling tools, there is a more accurate approach to unknown primary cancer. Metastasis to bone is not a rare phenomenon, because any tumour can metastasise to bone, so it is a common clinical scenario. The role of clinical history, physical examination, laboratory tests, radiographic studies and immunohistochemistry is critical for a successful diagnostic strategy. Subsets of unknown primary cancers can be identified primarily on the basis of histopathological findings, the pattern of spread and serum markers. New immunohistochemical markers and tissue-of-origin profiles may establish presumable primary sites to unknown primary cancer on the basis of immunohistochemical and molecular patterns. We present a case of a 57-year-old woman without a cancer history, who had primary bone metastasis as the first manifestation of an occult primary tumour.
A 56-year-old patient was admitted to our hospital, presenting with dysphagia as the only symptom. He was very concerned about this difficulty in swallowing. Diseases of the upper digestive tract were suspected, but further investigations revealed a neurological disorder. He had suffered a brain stem stroke and, as a consequence, developed an aspiration pneumonia. What seemed a digestive disorder was indeed a brain stem stroke, therefore we had to deal with the diverse impacts of this condition.
Clostridial soft tissue infections are infrequent, but can be life-threatening when associated with certain underlying conditions, such as immunosuppression or malignancy. When bacteraemia occurs, it can be accompanied by haemolysis. Only surgical removal of the focus of infection and early onset of antibiotic therapy can prevent a very poor outcome. We describe the case of a man aged 65 years who presented with sepsis, haemolysis and rapid worsening. The identification of a gas-forming liver abscess, the early percutaneous drainage and the prompt initiation of antibiotic treatment were the key factors in the outcome of this patient.
Chordoid gliomas are rare tumours. Despite being considered low-grade neoplasms, recent reviews have reported generally poor prognosis due to complications involving severe hypothalamic symptoms. We report a patient aged 30 years with chordoid glioma. What makes this case report interesting is the presence of neurogenic fever, which was already present before the final diagnosis of the brain tumour and also several months after the surgical removal. Since the patient underwent a subtotal resection of the tumour, it remains unclear whether the fever was due to hypothalamic dysfunction or remnants of the tumour. We also performed temperature logging with a continuous-monitoring recording device.
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.
