Coexistence of small bowel gastrointestinal stromal tumor, small bowel adenocarcinoma, and ganglioneuroma in a patient with neurofibromatosis type I and caused intussusception
We report a synchronous case of small bowel gastrointestinal stromal tumor, small bowel adenocarcinoma, and ganglioneuroma complicated by intussusception in an old woman with NF-I. The patient presented with a 2-month history of abdominal pain and multiple neurofibromas and café au lait macules was found all over the patient's body. The enhanced computed tomography revealed a terminal ileal tumor which was significantly enhanced with secondary intussusception. The tumor of the ileum was considered to be NF-I-associated intestinal neurofibroma.Postoperative pathology and immunohistochemistry showed that the terminal ileoce...

Synchronous rectal adenocarcinoma and intestinal mantle cell lymphoma: A case report
CONCLUSION: Synchronous rectal adenocarcinoma and intestinal MCL presenting as multiple lymphomatous polyposis are extremely rare. MCL is often discovered fortuitously when rectal cancer is diagnosed. The coexistence of these tumors poses treatment challenges.PMID:37727717 | PMC:PMC10506007 | DOI:10.12998/wjcc.v11.i24.5772

Emergency management of colon adenocarcinoma in an adolescent female: A rare case report
Incisional biopsy of the tumor, peritoneal deposits, and excised specimen. Key Clinical MessageColorectal carcinoma (CRC) should be suspected in pediatric patients with a bowel obstruction in an emergency setting. Evidence-based surgical management with chemotherapy is crucial to prevent adverse outcomes.AbstractCRC should be suspected in pediatric patients presenting to the emergency with unspecified abdominal pain. An erect X-ray abdomen and a colonoscopy should be initial diagnostic tests. If colonoscopy raises suspicion of CRC, a biopsy during colonoscopy is indicated. A computed tomography scan of the chest, abdomen, ...

A pancreatic adenocarcinoma mimicking hepatoid carcinoma of uncertain histogenesis: A case report and literature review
Oncol Lett. 2023 Aug 28;26(4):442. doi: 10.3892/ol.2023.14029. eCollection 2023 Oct.ABSTRACTIn rare cases, metastatic adenocarcinomas of different origin may exhibit the features of hepatoid carcinoma (HC), a rare malignant epithelial tumor, most commonly occurring in the ovaries and stomach, as well as in the pancreas and biliary ducts. A case of a 72-year-old female patient who developed a highly aggressive, poorly differentiated pancreatic ductal adenocarcinoma with peritoneal carcinomatosis, demonstrating hepatoid differentiation upon conventional hematoxylin and eosin staining is reported in the present study. The pat...

S-1 as an alternative treatment after 5-fluorouracil-induced coronary vasospasm in a patient with small bowel adenocarcinoma: a case report
Abstract5-Fluorouracil (5-FU) is a chemotherapeutic agent used worldwide to treat various solid tumors. It may cause adverse cardiotoxic events, the most common of which is coronary vasospasm. Recently, the 2022 European Society for Medical Oncology guidelines for metastatic colorectal cancer recommended S-1 as an alternative therapy after 5-FU-induced cardiotoxicity; however, only limited data on Asian patients are available. Here, we report a case of safe administration of S-1 to a 72-year-old Japanese female patient with metastatic small bowel adenocarcinoma who developed 5-FU-induced coronary vasospasm. While receiving...

Presentation of Gastrointestinal Stromal Tumor, Pancreatic Adenocarcinoma, and Gastric Adenocarcinoma in a Woman With No Identifiable Genetic Abnormalities
This report details the first known case of co-occurrence of gastrointestinal stromal tumor (GIST), pancreatic adenocarcinoma, and gastric adenocarcinoma in an individual with no identifiable genetic abnormalities. The patient is a 57-year-old female who presented with abdominal pain. CT scan demonstrated a pancreatic mass, and endoscopic ultrasound demonstrated an additional gastric mass. Biopsy of both masses demonstrated adenocarcinoma; however, the masses were found to have different origins. The patient underwent neoadjuvant chemotherapy with excellent response. She then underwent surgical intervention, which demonstr...

Case Report: A testicular torsion as an initial presentation of a patient with metastatic cecum signet-ring cell cancer
In conclusion, differential diagnosis should be considered for rare testicular neoplasms, as was seen in this rare occurrence of testicular torsion in a patient who initially presented with metastatic colorectal cancer. A correct preoperative diagnosis can change the management and outcome. This report shares our reasons for misdiagnosis and opinions on diagnosing and treating this kind of case.

Molecular pathology and clinical treatment of independent HPV primary serous carcinoma of the uterine cervix (USCC): A case report
1. Procedure for diagnosis HPV-independent adenocarcinomas of the uterine cervix. 2. Procedure for treating HPV-independent adenocarcinomas of the uterine cervix. AbstractOn October 23, 2020, a 69-year-old Chinese female patient was admitted to Yuncheng Hospital due to a history of postmenopausal bleeding and lower abdominal pain for 5 months. The HPV test and pathology results indicated the presence of independent HPV in primary serous carcinoma of the uterine cervix. The genetic testing identified variants of uncertain significance (PAX8 p.Tyr 410 Ter and TP53 p.Asn 247 Ile), microsatellite instability stable (MSI-S), tu...

Enteritis cystica profunda
We reported the case of a 45-year-old female, suffering from a Crohn's disease, with a Koenig's syndrome, diarrhea, abdominal pain and weight loss. The colonoscopy and the abdominopelvic scan showed a terminal ileal stenosis, with parietal calcifications. A surgical ileocecal resection was decided. Gross examination of the ileocecal resection showed a thickening of the ileal wall, with many mucin-filled cysts measuring 1mm to 2cm, with some calcifications. The ileal mucosa was ulcerated, and showed a stenotic sector extending over 3cm. Histological examination showed acute ulcerated ileitis lesions, with chronic ileitis le...
