Large-cell neuroendocrine carcinoma (LCNEC) of the endometrium is an extremely rare, high-grade malignant tumor. We herein report a case of a rapidly growing LCNEC arising in the endometrium. A 52-year-old woman was referred to Toyooka Hospital (Tooyoka, Japan) due to genital bleeding in February 2016. There had been no abnormalities on a regular gynecological and physical examination 3 months prior to the consultation. Imaging (computed tomography and magnetic resonance imaging) and a pelvic examination revealed a tumor sized 16...

Intramedullary melanotic schwannomas (IMS) are rare lesions, with only 8 cases reported in the literature to date. We herein describe the case of a 40-year-old male patient with an IMS of the cervical cord, which, to the best of our knowledge, is the ninth reported case of IMS, and review the relevant literature. The patient presented with numbness of the left arm that gradually worsened over a period of 4 months. Magnetic resonance imaging (MRI) of the cervical spine with gadolinium enhancement revealed an intramedullary lesion at the level of C1-C2...

The aim of the present study was to investigate whether unintentional body weight loss (BWL) provides additional clinical information in terms of tumor progression and prognosis in non-metastatic colon cancer. In the present study, a total of 2,406 consecutive colon cancer patients without metastasis were retrospectively enrolled. Unintentional BWL was defined as loss of >5% of body weight within the last 6-12 months, or defined subjectively upon fulfillment of at least two of the following: Evidence of change in clothing size and corroboration of the reported weight loss by family or friend...

Paratesticular liposarcoma is an infrequent tumor characterized by a growing, painless, inguinal or scrotal mass. Only about 200 cases have been reported as of yet in literature, however there are a few cases regarding giant paratesticular liposarcoma measuring over 10 cm. The disease may be commonly misdiagnosed prior to operation. Improper treatment tends to lead to local recurrence and distant metastasis. The current report presents a case of a 51-year-old patient with a large, painless right scrotum. Magnetic resonance imaging revealed a 7...

The present study reports a rare case of radiation recall pneumonitis attributed to ifosfamide that was used as a single antitumor agent for a recurrent malignant soft tissue tumor, arising from the chest wall. A 74-year-old man, who had a mass in his right upper chest wall, underwent surgical excision under the diagnosis of chronic expanding hematoma. He was referred to the present hospital with a recurrent tumor as the excised tumor was diagnosed as undifferentiated high-grade sarcoma. The extension of the tumor following previous surgery was aggressive and the tumor margins were unclear on magnetic resonance imaging...

Squamous cell carcinoma (SqCC) of the breast should be differentiated between the primary skin keratinizing squamous carcinoma and squamous metaplastic cancer. In the current study, the cases of two patients who were diagnosed with SqCC originated from skin and the breast were discussed. A fine-needle aspiration biopsy confirmed the presence of atypical squamous cells. In both cases, the microscopic examination of the surgical specimen revealed a malignant neoplasm differentiated into SqCC characterized by keratinizing cancer cells with abundant eosiphilic cytoplasm with large, hyperchromatic vesicular nuclei...

Castleman's disease (CD) is a lymphoproliferative abnormality, also referred to as giant lymph node hyperplasia or follicular lymphoid hyperplasia. The occurrence of CD in the liver is rare. Radiological diagnosis of hepatic CD by computed tomography (CT) and magnetic resonance imaging (MRI) remains difficult. On imaging, hepatic CD is often expressed as a single, well-defined soft tissue lesion, with rare cystic degeneration and focal necrosis. The CD lesions appear as hypervascular with abundant cell proliferation on CT and MRI...

Duodenal metastasis from renal cell carcinoma (RCC) is rare. The current case report presents a very rare case of late duodenal metastasis from RCC with newly developed malignant lymphoma (diffuse large B-cell lymphoma: DLBCL) at the same time. A 64-year-old man with systemic lymph nodes swelling who had undergone left nephrectomy for RCC 25 years previously, was admitted to the present hospital. Inguinal lymph node biopsy was performed, leading to a diagnosis of DLBCL. fluorine-18-fluorodeoxy-glucose (18 F-FDG)-positron emission tomography (PET)/computed tomography (CT) revealed multiple lymph nodes, spleen, and ileocecal lesions...

The solitary fibrous tumor (SFT) was first described as a mesenchymal tumor of fibroblastic type, present in the pleura. The head and neck area is the third most common site of SFT occurrence. Numb chin syndrome (NCS) is a rare neurological symptom. The current report describes the case of a 39-year-old female patient referred to the present hospital with NCS, which was later observed to be due to a large SFT in the infratemporal fossa. Computed tomography and magnetic resonance images were taken and subsequent examination of these images revealed a space occupying mass (52×50×40 mm) in the infratemporal fossa...

Qi-Bing Wu, Xin Sheng, Ning Zhang, Ming-Wei Yang, Fan Wang
Colorectal cancer (CRC) is among the main tumor-related causes of death worldwide. The fact that the majority of the patients develop resistance to chemoradiotherapy (CRT) is a major obstacle for the treatment of CRC. In order to develop more effective treatment strategies, it is crucial to elucidate the mechanisms underlying the development of resistance to CRT. Several studies have recently indicated the regulatory effects of microRNAs (miRNAs) in response to antitumor agents. For example, miR-34a attenuates the chemoresistance of colon cancer to 5-FU by inhibiting E2F3 and SIRT1...

The prognosis of patients with unresectable or recurrent pancreatic cancers is very poor. Prior to development of nab-paclitaxel (PTX) plus gemcitabine (GEM) therapy and FOLFIRINOX therapy, there was no recommended third-line chemotherapy after 5-fluorouracil (5-FU) and GEM-based regimens. The present study conducted a Phase I clinical trial of weekly low-dose PTX as a third-line palliative chemotherapy for patients with pancreatic cancer. PTX was administered on days 1, 8, 15, and 22 of each cycle, repeated twice as follows: Level 1, 40 mg/m2 (n=6); Level 2, 50 mg/m2 (n=4)...

As with other genitourinary malignancies, a variety of paraneoplastic syndromes have been revealed to occur in patients with prostate cancer. Stauffer's Syndrome is a well-described clinical syndrome which manifests via intrahepatic cholestasis in patients with renal cell carcinoma. Less common is intrahepatic cholestasis occurring in association with prostate cancer. The current case report discusses a 67-year-old man presenting with liver failure secondary to intrahepatic cholestasis co-existing with metastatic prostate adenocarcinoma...

A meta-analysis was performed to evaluate the accuracy of optical coherence tomography (OCT) for diagnostic accuracy studies in bladder cancer patients. English language studies reporting the diagnostic accuracy of OCT for bladder cancer were retrieved from the PubMed, EMBASE and Cochrane Library databases in December 2014. Histopathology was a reference standard. Sensitivities, specificities, positive likelihood ratios and negative likelihood ratios were calculated, and summary receiver operating characteristic curves were drawn to determine the diagnostic accuracy of OCT...

Bronchobiliary fistula (BBF) is a rare condition, defined as an abnormal communication between the bronchial system and the biliary tree. Patients with this condition usually present with massive biliptysis, and the mortality rate is high. BBF has been reported to occur in patients with congenital conditions, complications of trauma, hepatic abscesses and biliary tract obstruction (surgical as well as non-surgical). However, to the best of our knowledge, BBF as a complication of transcatheter arterial chemoembolization (TACE) for hepatocellular carcinoma (HCC) has not been reported to date...

Although gastric metastases have been estimated to occur in less than 2% of cancer patients, an increased use of upper digestive tract endoscopy allows for a higher detection of secondary gastric tumors. We describe the case of a 66-year-old male patient presenting with mild pain in the sternum and upper abdominal area. Physical examination revealed a right parietal skull tumor, with no other significant clinical changes. Upon exclusion of an acute coronary syndrome, upper digestive tract endoscopy was performed, showing the presence of an ulcerated tumor located in the gastric fundus...

Abiraterone acetate (AA), a CYP17 inhibitor, now has a crucial role in the treatment of castration-resistant prostate cancer (CRPC), and previous studies have reported several prognostic clinical factors for AA treatment. The neutrophil-to-lymphocyte ratio (NLR) has also been investigated for a CRPC treatments in a few reports, however it has not been identified to be a prognostic factor for AA treatment in Japanese patients. The present study aimed to assess the association of the baseline NLR with the overall survival (OS) in CPRC patients treated by AA...

A granular cell tumor (GCT), is a rare soft tissue tumor which may occur throughout the body, usually in the head and neck, skin or subcutaneous tissues of the trunk and upper extremities, and female genital region. A total of 5-8% of all cases of GCTs occur in the breast. GCT of the breast may mimic breast cancer both clinically and radiologically. GCTs are usually benign and solitary; however, approximately 2% occur as malignant tumors. Benign GCTs are treated with wide local excision and are associated with a good prognosis...

The sensitivity of bile cytology for biliary tract cancer varies from 6-64%, and hence remains unsatisfactory. Sialylated carbohydrate antigen KL-6 mucin is positive in biliary tract cancer tissues and serum KL-6 levels are significantly increased in intrahepatic ductal adenocarcinoma patients compared with healthy individuals. The aim of the present study was to evaluate the usefulness of the KL-6 concentration of bile for the diagnosis of biliary tract cancer. Bile cytology and measurements of bile KL-6 concentration were conducted for 43 patients (25 biliary tract cancers and 18 benign biliary disease)...
