In rare instances, stroke may precede a diagnosis of cancer and be the first clinical evidence of an underlying malignancy.Cerebral infarction mostly complicates lymphomas, carcinomas, and solid tumors. Malignancy-related thromboembolism can present as acute cerebral infarction, nonbacterial thrombotic endocarditis and migratory thrombophlebitis. It is generally attributed to a cancer-related hypercoagulable period, chronic disseminated intravascular coagulopathy (DIC), or tumor embolism. We reported a case of malignancy-related thromboembolism from an undiagnosed pancreatic adenocarcinoma in a 54-year-old man, who presented with recurrent ischemic stroke due to chronic DIC. He died of the underlying malignancy despite the appropriate institution of anticoagulation therapy.This case emphasizes that cerebral infarction may be the first manifestation of an undiagnosed cancer. If there is laboratory or clinical evidence associated with DIC, patients with a cerebral infarct of an unknown etiology should be investigated for a malignant process. The optimal method of anticoagulation in cancer patients with thromboembolic disease (TED) remains unclear.

A 26-year-old unmarried woman with irregular menstruation for 4 years was admitted for an intrauterine space-occupying mass. Pathological examination before surgery showed moderately to poorly differentiated endometrial adenocarcinoma. The patient underwent laparoscopically assisted epifascial panhysterectomy with bilateral salpingo-oophorectomy. Pathological examination of the surgical specimens reported moderately to poorly differentiated endometrial adenocarcinoma and stage II clear cell carcinoma. The patient then received chemotherapy and remained alive without evidence of recurrence. Young women with polycystic ovarian syndrome are at high risk of developing endometrial carcinoma, but concurrent clear cell carcinoma is rare. Careful evaluation before and after treatment are essential to improve the patients prognosis.

We report a case of mucinous adenocarcinoma arising in the perianal soft tissue in association with chronic fistula-in-ano in a 43-year-old man who had a relapse of perianal pain and bloody discharge after six years of defaulted follow-up. He underwent magnetic resonance (MR) and computed tomography imaging with correct identification of the disease entity on imaging. Mesh-like septations and an enhancing solid component with high diffusion-weighted imaging (DWI) and intermediate apparent diffusion coefficient signals were observed. He underwent abdominoperineal resection of the tumour but succumbed due to postoperative complications. Literature on the MR imaging features of this tumour remains scarce. We highlight the MR imaging features, including those seen on DWI, which were useful in making the correct diagnosis. Though uncommon, this would be an important condition to recognise since assessment of fistula-in-ano by MR imaging is considered to be the standard of care in current clinical practice. The clinical features of this entity are also briefly discussed.

A colon cancer presenting as psoas muscle abscess is very rare. A 27-year-old woman was admitted with abdominal pain, fever, and discomfort on left thigh. She had been administered on anti-tuberculosis medication for colonic tuberculosis since 3 months ago. Abdominal CT scan revealed a mass lesion obstructing the descending colon with an abscess formation within left psoas muscle. We undertook segmental resection of obstructing descending colon after the percutaneous drainage of psoas abscess. The pathologic report was mucinous adenocarcinoma of the colon. We report the first case of colon cancer manifested with psoas abscess in Korea, with the review of literature associated with the correlation of colon cancer and tuberculosis.

To investigate the immunophenotypings of malignant epithelial mesothelioma (MEM), and to seek the valuable markers in distinguishing peritoneal MEM from peritoneal metastatic ovarian adenocarcinoma (OA) and colorectal adenocarcinoma (CA), immunohistochemical SP method was used to detect expressions of HBME-1, E-cadherin, CA19-9, MOC-31 and CK7 in paraffin-embedded tissues of 18 cases of MEM, 20 OA and 20 CA. The results showed that there was a significant difference in the expressions of E-cadherin, CA19-9 and MOC-31 between MEM and OA group (P<0.05). Similarly, the difference in the expression of HBME-1, E-cadherin, CA19-9, MOC-31 and CK7 between MEM and CA groups is significant (P<0.05). These results indicate that HBME-1 could be used as a positive marker in distinguishing MEM from CA. E-cadherin, CA19-9 and MOC-31 are considered to be useful negative markers in diagnostic distinction between MEM and metastatic adenocarcinomas, including OA and CA. CK7 is the best positive marker in distinguishing MEM from CA, but this marker appears to be valueless in discriminating MEM from OA.
