Delayed relapse of Churg-Strauss syndrome manifesting as colon ulcers with mucosal granulomas: 3 cases

Churg-Strauss syndrome (CSS) is characterized by small vessel vasculitis and extravascular granulomas. The American College of Rheumatology classification criteria for CSS include asthma, eosinophili, and clinical manifestation of vasculitis. Gastrointestinal (GI) manifestations occur in 30% of patients, but are inaugural in only 16%. They denote vasculitis of the stomach and small bowel wall, and consist in protean, nonspecific pain. GI involvement is of adverse prognostic significance in CSS. Ulcer formation in the GI tract mucosa is a rarer manifestation, usually discovered upon laparotomy or autopsy. We describe 3 new cases of colonic ulcers in CSS. Unusual features were diagnosis of the ulcers during a delayed relapse and presence of eosinophilic granulomas within the mucosa.     

Focal ultrasound lesions in liver cirrhosis diagnosed as regenerating nodules by fine-needle biopsy

In the period 1985–1988, 62 focal liver lesions in 58 cirrhotic patients were studied by ultrasonography; 12 of these focal lesions were documented to be regenerating lesions by echo-guided fine-needle biopsy. During an average follow-up period of 10.2 months (range 3–22 months), hepatocellular carcinoma was subsequently found in 10 of the cases of regenerating nodules, whereas the initial diagnosis of regenerating nodule was confirmed in the remaining two cases. Based upon this finding, it is suggested that every focal mass visualized by ultrasonography in a cirrhotic liver should either be considered to be a neoplastic lesion or at least a preneoplastic lesion if the possibility of either a metastatic or benign lesion (eg, hemangiomas, focal fatty liver change areas) can be excluded. Therefore either fine-needle aspiration or biopsy of all ultrasonographically revealed mass lesions within a cirrhotic liver is advised, such that early appropriate treatment for hepatocellular carcinoma can be instituted.     

Gastric ulcer penetrating to liver diagnosed by endoscopic biopsy

Liver penetration is a rare but serious complication of peptic ulcer disease. Usually the diagnosis is made by operation or autopsy. Clinical and laboratory data were no specific. A 64-year-old man was admitted with upper gastrointestinal bleeding. Hepatic penetration was diagnosed as the cause of bleeding. Endoscopy showed a large gastric ulcer with a pseudotumoral mass protruding from the ulcer bed. Definitive diagnosis was established by endoscopic biopsies of the ulcer base.     

Churg-Strauss syndrome with myocarditis manifesting as acute myocardial infarction with cardiogenic shock: case report and review of the literature

A patient with a two-year history of worsening asthma presented with chest pain and shortness of breath. She developed cardiogenic shock. Analysis of blood chemistry detected increased troponin I concentration. Her electrocardiographic changes were consistent with a diagnosis of anteroseptal myocardial infarction. However, angiography showed normal coronary arteries. Left ventriculography showed severe mitral regurgitation and global hypokinesis. Peripheral eosinophilia was detected. Subsequent endomyocardial biopsy showed myocarditis with prominent eosinophil and plasma cell components. Churg-Strauss syndrome was diagnosed based on her history of asthma, evidence of peripheral eosinophilia and results of endomycardial biopsy. Treatment with a high dose of corticosteroids was initiated. As symptoms of heart failure improved - without recurrence of cardiac and respiratory symptoms - the dose of corticosteroids was gradually reduced. Eight months after her original presentation, she developed urticarial lesions on her abdomen and legs, with muscle soreness but no other associated symptoms. She was treated with a combination of prednisone and dapsone. After the diagnosis of Churg-Strauss syndrome, the patient remained symptom free with a normal ejection fraction for 15 months while taking prednisone.     

Churg-Strauss syndrome complicated by colon erosion, acalculous cholecystitis and liver abscesses

We report on a case of Churg-Strauss syndrome (CSS) with colon erosion, cholecystitis and liver abscesses. A 21-year-old woman with a history of bronchial asthma for 3 years was admitted with a complaint of abdominal pain. Laboratory findings included remarkable leukocytosis and eosinophilia, and a colonoscopy revealed erosion from the rectum to the ileocecal region. In addition, a colonic biopsy specimen showed necrotizing vasculitis and marked eosinophilic infiltration. On the basis of the clinical features and histopathological findings, she was diagnosed with CSS and subsequently treated with oral prednisolone, after which the eosinophilia and abdominal pain disappeared. However, on the 15th d in hospital she developed cholecystitis and liver abscesses. She was therefore treated with antibiotics and as a result went into clinical remission.     

Vertigo and Parinaud's syndrome as presentation of Churg-Strauss syndrome.

Intracranial complications are rare in Churg-Strauss syndrome (CSS). Cerebral infarctions are the most common intracranial presentation, usually after the clinical diagnosis of CSS had been established. We present a case of vertigo and Parinaud's syndrome as presentation of CSS in an asthmatic patient. Clinical examination revealed upward gaze limitation and bilateral midriasis. A cranial computed tomography scan showed a small round hypoattenuating lesion located in the right thalamic-mesencephalic region, which was later confirmed by magnetic resonance imaging. There was eosinophilia of more than 50%, and p-ANCA were positive. After steroid treatment was started, vertigo and diplopia resolved, and eosinophilia was reduced. After 24 months follow-up, the patient remains stable, with negative p-ANCA, taking 20 mg prednisone daily. Further magnetic resonance exams have shown findings that were similar to those of previous studies. This case shows how vertigo and transient diplopia may be the first symptoms of neurological complications in patients with CSS.     

Olfactory esthesioneuroma manifesting as Schwartz-Bartter syndrome

INTRODUCTION: Olfactory esthesioneuroblastoma is an uncommon neuroectodermal tumor originating from the olfactory epithelium, which is rarely associated with hormone excess syndrome. EXEGESIS: Asymptomatic olfactory esthesioneuroblastoma was diagnosed in a 22-year-old man who presented a syndrome of inappropriate antidiuretic hormone secretion. Following surgery, the immunohistochemical analysis demonstrated the existence of neurophysin hormone in tumoral cells. CONCLUSION: This case provides evidence that olfactory esthesioneuroblastoma can be uncovered by inappropriate antidiuretic hormone secretion.     

A case of Churg-Strauss syndrome: tissue diagnosis established by sigmoidoscopic rectal biopsy.

A case is presented of Churg-Strauss syndrome in a young man in whom the definitive diagnostic procedure was a full thickness sigmoidoscopic rectal biopsy, with submucosal sampling. Gastrointestinal changes in Churg-Strauss syndrome, a rare systemic illness characterised by asthma, blood and tissue eosinophilia, vasculitis, and granulomatous inflammation are common but poorly reported. The endoscopic and histopathological features of a case are described and emphasise the potential value of a limited sigmoidoscopy in establishing the diagnosis, when lower gastrointestinal symptoms are present.     

Churg-Strauss syndrome presenting as spontaneous subarachnoid haemorrhage

Churg–Strauss syndrome (CSS) is a systemic small-vessel vasculitis characterised by the presence of asthma and eosinophilia. Central nervous system involvement (cerebral infarctions or intracerebral haemorrhage) is rare in CSS. Spontaneous subarachnoid hemorrhage (SAH) has been described in other systemic vasculitides. SAH is exceptional in CSS. We present a 47-year-old woman with CSS presenting as a spontaneous SAH with cerebral angiography findings consistent with vasculitis of the basilar artery and without aneurysms or arteriovenous malformations. She received treatment with prednisone and cyclophosphamide, and 2 months later the basilar artery was normal on magnetic resonance angiography.

Inflammatory pseudotumor of the liver and spleen diagnosed by percutaneous needle biopsy

An inflammatory pseudotumor (IPT) is a relatively rare lesion characterized by chronic infiltration of inflammatory cells and areas of fibrosis. IPTs are difficult to diagnose because of the absence of specific symptoms or of characteristic hematological or radiological findings. In this study, a case of a woman aged over 70 years was reported, who presented with a general malaise lasting more than two months. A computed tomography scan demonstrated a diffusely spread lesion of the liver with a portal vein occlusion and a splenic lesion surrounded by a soft density layer. Since the percutaneous liver biopsy showed findings that suggested an IPT, although the radiological findings did not exclude the possibility of a malignancy, we performed a percutaneous spleen biopsy to enable a more definitive diagnosis. The microscopic findings from the spleen specimen lead us to a diagnosis of IPT involving the liver and spleen. Subsequent steroid pulse therapy was effective, and rapid resolution of the disease was observed.     

Myocardial involvement in Churg-Strauss syndrome: the role of endomyocardial biopsy

A Chinese adult with Churg-Strauss syndrome with prominent cardiac involvement is described. The myocardial impairment initially showed good response to corticosteroid and cyclophosphamide. However, the cardiac status deteriorated later despite the absence of disease activity elsewhere. Endomyocardial biopsy was performed to determine the possibility of isolated myocardial relapse in case additional immunosuppression would be beneficial. Histology of the endomyocardial biopsy revealed myocardial fibrosis. Since cardiac involvement is the major cause of mortality in this condition and delayed treatment can lead to intractable cardiac failure, we advocate that endomyocardial biopsy should be performed more liberally and possibly serially to assess the disease activity in the myocardium. Immunosuppression may then be adjusted. To our knowledge, the occurrence of Churg-Strauss syndrome in Chinese has not been reported in the English literature.     

Multifocal intraportal invasion of breast carcinoma diagnosed by laparoscopy-assisted liver biopsy

Hepar lobatum carcinomatosum (HLC) is defined as an acquired hepatic deformity consisting of an irregularly lobulated hepatic contour caused by intravascular infiltration of metastatic carcinoma. To date, only nine cases of HLC have been reported in the literature. We report a case of a 68-year-old woman showing hepatic metastasis of breast carcinoma in radiologically unidentified form. Initially, she received left partial mastectomy for breast cancer but solid hepatic metastases were identified in S2 and S6, 9 mo after surgery. Then, they responded to chemotherapy and radiologically disappeared. After radiological disappearance of the liver tumors, the patient's blood chemistry showed abnormal liver function. A CT scan demonstrated heterogeneous enhancement effect in the liver in the late phase, suggesting uneven hepatic blood supply. Hepatic deformity was not obvious. Laparoscopy revealed a slightly deformed liver surface with multiple indentations and shallow linear depressions. Furthermore, a wide scar was observed on the surface of S2 possibly at the site where the metastatic tumor existed before chemotherapy. Liver biopsy from the wide scar lesion showed intraportal tumor thrombi with desmoplastic change. Because of its similarity to the histology of the original breast cancer, we concluded that the hepatic functional abnormalities and slightly deformed liver surface were derived from the circulatory disturbance caused by microscopic tumor thrombi. Besides, since the wide scar was located at the site of the pre-existing tumor, it is probable that chemotherapy was an important cause of fibrous scarring as a result of tumor regression. These morphologic findings are compatible with those of HLC. Laparoscopy-assisted liver biopsy was useful to make definite diagnosis, even though the hepatic deformity was radiologically undetectable.     

Leishmaniasis diagnosed by liver biopsy: management of two atypical cases

Two patients presenting with pyrexia of unknown origin were diagnosed as having visceral leishmaniasis based on the presence of Leishmania donovani bodies in liver tissue. Of particular interest is that these two case reports suggest that in patients with pyrexia of unknown origin, a liver biopsy for L. donovani bodies should be considered even when several months have passed since leaving an endemic area, when splenomegaly is absent, when bone marrow examination and serology are not diagnostic, and even when abnormal coagulation necessitates a transjugular liver biopsy.
