Multiple hepatic sclerosing hemangioma mimicking metastatic liver tumor successfully treated by laparoscopic surgery: Report of a case

AbstractIntroductionHepatic sclerosing hemangioma is a very rare benign tumor, characterized by fibrosis and hyalinization occurring in association with degeneration of a hepatic cavernous hemangioma. We report here a rare case of multiple hepatic sclerosing hemangioma mimicking metastatic liver tumor that was successfully treated using laparoscopic surgery.Presentation of caseA 67-year-old woman with multiple liver tumors underwent single-incision laparoscopic sigmoidectomy under a diagnosis of advanced sigmoid cancer with multiple liver metastases. Examination of surgical specimens of sigmoid colon revealed moderately differentiated adenocarcinoma invading the serosa, and no lymph node metastases. Serum levels of carcinoembryonic antigen and carbohydrate antigen 19-9 remained within normal limits throughout the course. Two months after sigmoidectomy, the patient underwent laparoscopic partial hepatectomy of S1 and S6 of the liver and cholecystectomy. Histopathological examination showed that the tumors mainly comprised hyalinized tissue and collagen fibers with sporadic vascular spaces on hematoxylin and eosin-stained sections, yielding a diagnosis of multiple hepatic sclerosing hemangioma. No evidence of recurrence has been seen as of 21 months postoperatively.DiscussionDifferentiating multiple sclerosing hemangiomas from metastatic liver tumors was quite difficult because the radiological findings were closely compatible with liver metastases. Laroscopic hepatectomy provided less blood loss, a shorter duration of hospitalization, and good cosmetic results.ConclusionSclerosing hemangioma should be included among the differential diagnoses of multiple liver tumors in patients with colorectal cancer. Laparoscopic hepatectomy is useful for diagnostic therapy for undiagnosed multiple liver tumors

A Case of Takotsubo Cardiomyopathy after Surgery for Common Bile Duct Stones

Takotsubo cardiomyopathy (TC) is a rare reversible circulatory syndrome often detected in elderly patients after general surgery. We report the case of an 85-year-old woman who was admitted for obstructive jaundice and underwent ERCP and ENBD before operation. She finally underwent cholecystectomy and choledocholithotomy with the diagnosis of gallbladder and common bile duct stones. In the evening just after the operation, without symptoms of cardiac failure, her ECG suddenly exhibited abnormal ST-T elevation in leads II, III, and V2-V6, though neither CPK(MB) nor troponin T was elevated. Echocardiogram demonstrated basal hyperkinesis and apical dyskinesis, suggesting TC. Conservative treatment enabled recovery, ECG was normalized in a month, and the postoperative course was satisfactory. The stress on her during treatment might have been a cause of this unique cardiomyopathy, and it should be recalled that TC is a potential complication of hepato-biliary-pancreatic surgery

Recurrent Ascending Colon Cancer Manifesting as Inferior Vena cava Thrombus

We report an extremely rare case of recurrent ascending colon cancer manifesting as inferior vena cava (IVC) thrombus. A 77-year-old woman previously diagnosed with ascending colon cancer underwent right hemicolectomy with lymph node dissection. Though the tumor invaded the retroperitoneum and involved the right ovarian artery and vein, curative operation was performed. The patient took 5-FU p.o. Two and a half years later, tumor thrombus in the IVC extending into the right atrium was incidentally found and diagnosed as recurrence of colon cancer by biopsy. RF-induced hyperthermia using 5-FU and CDDP i.v. was immediately performed, but she died after 6 months because of multiple liver and pulmonary metastases. In treating colon cancers invading the retroperitoneum, it should be recalled that some cases recur as tumor thrombus in the IVC and that close follow-up is therefore necessary

Long-term efficacy of lenvatinib for recurrent papillary thyroid carcinoma after multimodal treatment and management of complications: a case report

Abstract Background The advent of tyrosine kinase inhibitors (TKIs) has changed the treatment of RAI refractory, unresectable recurrent differentiated thyroid cancer (DTC), which was formerly treated with multidisciplinary remedies. Case presentation Here we describe the case of a 64-year-old woman who underwent total thyroidectomy with tracheal resection and suffered from a recurrent tumor in the neck and multiple lung and bone metastases 3 and 11 months, respectively, after the operation. Multimodal therapies, RI (I-131), EBRT, and taxane-based chemotherapy were ineffective, and sorafenib was started as a TKI. However, because of disease progression, sorafenib was replaced by lenvatinib after 9 months. The effect of lenvatinib has continued for more than 1 year and 9 months, and the patient has well survived. During the treatment period, a tracheal pin-hole fistula suddenly emerged, which was naturally cured by the temporary cessation of lenvatinib. Adverse events such as hypertension, proteinuria, and diabetes as innate complications have been successfully managed until the present according to our institute regulations. Conclusions Even where multimodal treatment was ineffective, lenvatinib was suggested to be an alternative treatment option for RAI refractory recurrent DTC and patient could have a chance to be controlled successfully
