We present a case of a 60-year-old woman with an isolated recurrent hemangiopericytoma of the liver. The patient presented with a palpable right upper quadrant abdominal mass, which occurred 7 years after undergoing resection of a malignant hemangiopericytoma arising from the greater omentum. She had not followed up 6 mo after surgery. Various imaging studies showed a single large, well-capsulated liver tumor with central necrosis, accompanied by hypervascularity typical of a vascular tumor. Preoperative laboratory HBsAg and anti-HCV workup were both negative. Under the impression of recurrent malignant hemangiopericytoma, right trisegmentectomy was performed to completely resect the tumor. Pathological examination confirmed the diagnosis of recurrent hemangiopericytoma. Even though the incidence of the hemangiopericytoma is relatively low, malignant hemangiopericytoma has a tendency to recur frequently after a long-term disease-free interval. Also, the recurrent hemangiopericytoma is not easily detected early during follow-up until it becomes symptomatic because there are no specific tumor markers, and because of the diversity with regard to site of recurrence. The authors suggest that Positron Emission Tomogram (PET) may be a useful tool for the detection of recurrent hemangioperioltoma. We describe herein some characteristics and behaviors of malignant hemangiopericytoma, particularly after surgical resection.展开更多

METHODS: We retrospectively studied 23 cases of UGC in Tongji Hospital, and compared their clinicopathological characteristics with 33 cases of preoperatively diagnosed gallbladder carcinoma (PDGC). RESULTS: The proportion of UGC coexisting with cholecystolithiasis was significantly higher than that of PDGC (x^2 = 13.53, P 〈 0.01). The infection rate of hepatitis B virus was 21.74% (5/23) in UGC and 30.30% (10/33) in PDGC. Nine (39.13%) of 23 patients with UGC and 8/33 (24.24) PDGC had contact with schistosome pestilent water. The rate of multiple pregnancies was 56.52% (13/23) in the patients with UGC and 42.42% (14/33) in PDGC. The primary location of the UGC was mostly in the neck and body of the gallbladder, and that of the PDGC was often in the body and bottom. The incidence of Nevin stage I and 11 UGC was significantly higher than that of PDGC (x^2 = 4.44, P 〈 0.05 and 2 = 4.96, P 〈 0.05) while that of Nevin stage V UGC was significantly lower than that of PDGC (x^2 = 7.59, P 〈 0.01). According to the grading of carcinoma, the incidence of well-differentiated UGC was significantly higher than that of PDGC (2 = 4.16, P 〈 0.05), and that of poorlydifferentiated UGC was significantly lower than that of PDGC (x^2 = 4.48, P 〈 0.05).CONCLUSION: There are different characteristics between UGC and PDGC, such as in primary location, malignant degree and incidence of coexistence with cholecystolithiasis. Cholecystolithiasis, hepatitis B, schistosome and multiple pregnancies were high risk factors for gallbladder carcinoma.展开更多

The improved safety of administration of daily low doses of AD has already been established and this regimen is used for long-term medication. Nevertheless, asymptomatic continuous liver injury by AD may increase the risk of step-wise progression of non-alcoholic fatty liver disease. We present an autopsy case of AD-induced liver cirrhosis in a patient who had been treated with a low dose of AD (200 rag/d) daily for 84 too. The patient was a 85-year-old male with a history of ischemic heart disease. Seven years after initiation of treatment with AD, he was admitted with cardiac congestion. The total dose of AD was 528 g. Mild elevation of serum aminotransferase and hepatomegaly were present. Liver biopsy specimens revealed cirrhosis, and under electron microscopy numerous lysosomes with electron-dense, whorled, lamellar inclusions characteristic of a secondary phospholipidosis were observed. Initially, withdrawal of AD led to a slight improvement of serum aminotransferase levels, but unfortunately his general condition deteriorated and he died from complications of pneumonia and renal failure. Long-term administration of daily low doses of AD carries the risk of progression to irreversible liver injury. Therefore, periodic examination of liver function and/or liver biopsy is required for the management of patients receiving long-term treatment with AD.展开更多

This extremely rare type of tumor occurs most commonly in superficial locations. The case we describe herein is that of a 60- year-old man with two large hepatic masses. The patient's tumor was removed radically through an incision due to the inconclusive imaging findings. Follow-up computed tomography showed no recurrence and metastasis after 37 months, suggesting that enucleation was adequate for tumor eradication. To our knowl-edge, this is the first reported case of low-grade myofibroblastic sarcoma in the liver in the English language literature.展开更多

Retrorectal cyst-hamartomas (RCH) are derived from remnants of the tail gut, the most caudal part of the embryonic hincl gut, which normally involutes by the 8^th wk of embryonic development (3-8 mm stage). They have specific radiological and histopathological features that distinguish them from other similar formations (dermoid cysts, enteric duplication cysts and teratomas). We report a patient with adenosquamous carcinoma arising within RCH, who underwent complete resection of the cyst through anterior laparotomy, and reached complete (recurrencefree for 14 mo, so far) functional recovery. The cyst was incidentally discovered during hysterectomy 12 years ago. Diagnostic, therapeutic arid histopathological aspects of this rare case are discussed. The mentioned pedod between diagnosis and surgical treatment suggests that RCH, given enough time, can develop malignant degeneration, and should be resected at the time of diagnosis.展开更多

It is involved in the regulation of multiple functions, including the control of the gastroin-testinal (GI) system under physiological and pathophys-iological conditions. Since the gut contains at least 400times more melatonin than the pineal gland, a reviewof the functional importance of melatonin in the gutseems useful, especially in the context of recent clinicaltrials. Melatonin exerts its physiological effects throughspecific membrane receptors, named melatonin-1 re-ceptor (MT1), MT2 and MT3. These receptors can befound in the gut and their involvement in the regulationof GI motility, inflammation and pain has been reportedin numerous basic and clinical studies. Stable levels ofmelatonin in the lower gut that are unchanged follow-ing a pinealectomy suggest local synthesis and, further more, implicate physiological importance of endogenous melatonin in the GI tract. Presently, only a small number of human studies report possible beneficial and also possible harmful effects of melatonin in case reports and clinical trials. These human studies include patients with lower GI diseases, especially patients with irritable bowel syndrome, inflammatory bowel disease and colorectal cancer. In this review, we summarize the presently available information on melatonin effects in the lower gut and discuss available in vitro and in vivo data. We furthermore aim to evaluate whether melatonin may be useful in future treatment of symptoms or diseases involving the lower gut.展开更多

It mostly affects adults at the average age of 60 years.These polyps are able to cause abdominal pain,gastrointestinal bleeding,intestinal obstruction or intussusception.In this paper we report a case of gastric TIP with unusual presenting features. METHODS:A child with gastric IFP was described and the literature was reviewed, RESULTS:A 4-year-old girl presented with fever for 2 months,arthralgia of knees and ankles,iron defidency anemia, and hypoalbuminemia.Her stool examination was positive for occult blood.The upper gastrointestinal study demonstrated a large Iobulated mass at the upper part of gastric body.Partial gastrectomy en blocwith this 5 cm×8 cm mass was subsequently performed.Pathological examination was consistent with IFP.Following the mass excision,her fever abruptly declined and disappeared together with anemia and arthralgia.She remained asymptomatic and the abdominal ultrasonography performed at the 24-month follow-up demonstrated no recurrence of the tumor. CONCLUSION:The etiopathogenesis of IFP still remains unclear,The presence of IFP throughout the gastrointestinal tract and its variable clinical appearances make it difficult to diagnose,The inflammatory symptoms found in this patient support the hypothesis of inflammatory benign lesions of IFP.展开更多

An 80-year-old man was admitted to our clinic for further investigation of a fever of unknown origin. He noted anorexia, weight loss and fatigue. His laboratory tests showed anemia and a great elevation of ESR, LDH, and β2 microglobulin. In CT and MRI scan, a soft tissue mass in the pancreas was observed. A repeated endoscopy after his admission revealed an ulcerated mass-like deformity of the duodenal bulb. Explorative laparotomy confirmed a diffuse spread of an unresectable malignant pancreatic mass extending to the adjacent organs. Duodenal and surgical biopsies identified an ALCL of T-cell lineage, ALK-. The patient died in the Intensive Care Unit due to hemodynamic instability.Our case is the first one indicating that primary pancreatic lymphoma should be suspected in a patient with pancreatic mass and elevated serum LDH and β2 microglobulin.展开更多

Here, we report a case of 70-year-old woman complaining of abdominal satiety, combined with non-specific pain in the right upper quadrant, qhe abdominal contrast-enhanced MR.I-scan revealed a large and thick-walled septus cystic lesion in the liver. During operation, the biliary fistula was confirmed in the cyst cavity. A silica gel tube was inserted via the cystic duct for cholangiography, which demonstrated communication between the cyst and biliary tract. We performed wide-scale cyst wall resection; the biliary fistula was completely repaired by the closure of communicated bile ducts. The postoperative course was uneventful, and the patient was discharged with no sign ofcholangitis or any other symptoms. The novel surgical management via wide resection of the cyst wall and closure of biliary communication proved to be an adequate and effective procedure for treating nonparasitic hepatic cysts with biliary communication.展开更多

The patient felt sudden pain in the right Achille's tendon in June 1999 with no apparent predisposing factors. Several months later he palpated a small pitting in the middle of the right Achille's tendon, which expanded gradually in size. In June 2000, two thirds of the tendon was diagnosed to be ruptured in a local hospital. Ten days later the tendon was ruptured completely when he felt sudden severe pain, numbness and distention, and he was unable to raise the heel. The lesion was healed three months later after being treated with a plaster model, but it was partially ruptured again 6 months later. Though the ruptured tendon was healed again with the help of a plaster model, he still suffered from local swelling and pain, which was aggravated during movement and made him difficult in walking, squatting down and standing up. During the examination, the right heel was found hyperemic and swollen with ecchymosis and tenderness. The tongue proper was dark red and the pulse thready and rapid. The condition was due to depletion and deficiency of liver-qi, stagnant blood with dampheat obstructing the collaterals. The principle of nourishing the liver and soothing the tendon was adopted, assisted by invigorating blood circulation and removing blood stasis, clearing heat and transforming dampness.展开更多

文摘The anti-arrhythmic agent amiodarone (AD) is associated with numerous adverse effects, but serious liver disease is rare. The improved safety of administration of daily low doses of AD has already been established and this regimen is used for long-term medication. Nevertheless, asymptomatic continuous liver injury by AD may increase the risk of step-wise progression of non-alcoholic fatty liver disease.

文摘Mr. Guo, 51 years old, paid his first visit on November 7, 2001. The patient felt sudden pain in the right Achille's tendon in June 1999 with no apparent predisposing factors. Several months later he palpated a small pitting in the middle of the right Achille's tendon, which expanded gradually in size. In June 2000, two thirds of the tendon was diagnosed to be ruptured in a local hospital. Ten days later the tendon was ruptured completely when he felt sudden severe pain, numbness and distention, and he was unable to raise the heel. The lesion was healed three months later after being treated with a plaster model, but it was partially ruptured again 6 months later. Though the ruptured tendon was healed again with the help of a plaster model, he still suffered from local swelling and pain, which was aggravated during movement and made him difficult in walking, squatting down and standing up. During the examination, the right heel was found hyperemic and swollen with ecchymosis and tenderness. The tongue proper was dark red and the pulse thready and rapid. The condition was due to depletion and deficiency of liver-qi, stagnant blood with dampheat obstructing the collaterals. The principle of nourishing the liver and soothing the tendon was adopted, assisted by invigorating blood circulation and removing blood stasis, clearing heat and transforming dampness.
