Endometriosis (E) and adenomyosis (A) are associated with a wide spectrum of symptoms and may present various histopathological transformations, such as the presence of hyperplasia, atypia, and malignant transformation occurring under the influence of local inflammatory, vascular and hormonal factors and by the alteration of tumor suppressor proteins and the inhibition of cell apoptosis, with an increased degree of lesion proliferation. Material and methods: This retrospective study included 243 patients from whom tissue with E/A or normal control uterine tissue was harvested and stained by histochemical and classical immunohistochemical staining. We assessed the symptomatology of the patients, the structure of the ectopic epithelium and the presence of neovascularization, hormone receptors, inflammatory cells and oncoproteins involved in lesion development. Atypical areas were analyzed using multiple immunolabeling techniques. Results: The cytokeratin (CK) CK7+/CK20− expression profile was present in E foci and differentiated them from digestive metastases. The neovascularization marker cluster of differentiation (CD) 34+ was increased, especially in areas with malignant transformation of E or A foci. T:CD3+ lymphocytes, B:CD20+ lymphocytes, CD68+ macrophages and tryptase+ mast cells were abundant, especially in cases associated with malignant transformation, being markers of the proinflammatory microenvironment. In addition, we found a significantly increased cell division index (Ki67+), with transformation and inactivation of tumor suppressor genes p53, B-cell lymphoma 2 (BCL-2) and Phosphatase and tensin homolog (PTEN) in areas with E/A-transformed malignancy. Conclusions: Proinflammatory/vascular/hormonal changes trigger E/A progression and the onset of cellular atypia and malignant transformation, exacerbating symptoms, especially local pain and vaginal bleeding. These triggers may represent future therapeutic targets.

Background: Non-variceal upper gastrointestinal bleeding (NVUGIB) remains a critical medical–surgical emergency associated with significant morbidity, mortality, and healthcare burden worldwide. Despite advances in diagnostic and therapeutic modalities, NVUGIB continues to pose complex clinical challenges, particularly in resource-limited settings. Methods: This retrospective observational study analyzed 364 consecutive adult patients diagnosed with NVUGIB and hospitalized at the First Surgical Clinic of the County Emergency Clinical Hospital Craiova between January 2009 and December 2014. Inclusion criteria required a confirmed diagnosis based on clinical presentation, laboratory findings, and upper gastrointestinal endoscopy (UGIE). Demographic variables, etiology, comorbidities, drug-induced triggers, laboratory parameters, onset-to-admission and onset-to-surgery intervals, endoscopic findings, therapeutic interventions (medical, endoscopic, surgical), rebleeding rates, and mortality were recorded and analyzed. Results were descriptively compared with historical data from the national and international literature. Due to the retrospective and aggregate nature of the data, survival analysis (Kaplan–Meier) was not applicable. Results: Peptic ulcers, erosive gastritis, Mallory–Weiss syndrome, and gastric neoplasms were the predominant etiologies. NSAID use, oral anticoagulation, and alcohol consumption emerged as major risk factors. Endoscopic hemostasis was achieved in the majority of cases; surgical intervention was required in 11.5% of patients, mainly for refractory or recurrent bleeding. The overall mortality rate was 10.9%, consistent with historical benchmarks. Comparative analysis revealed trends in etiology and management reflecting evolving clinical practice standards. Conclusions: NVUGIB remains a significant clinical challenge with persistent mortality and rebleeding risks. This cohort highlights the need for timely diagnosis, risk stratification, and an evidence-based therapeutic strategy integrating modern endoscopic and surgical options. An updated diagnostic and management algorithm is proposed to guide practical decision-making and optimize outcomes in similar tertiary care settings.

Background: Small intestinal neuroendocrine tumors (SI-NETs) are the most common malignancies of the small bowel. Although typically well differentiated and slow-growing, they may exhibit aggressive behavior, especially when diagnosed at an advanced stage. Objective: To illustrate the diagnostic and therapeutic challenges of advanced SI-NETs through a rare case presentation and a narrative review of recent studies in the literature. Methods: A narrative literature review was conducted using the PubMed database to examine the incidence, risk factors, diagnostic modalities, and treatment strategies for advanced-stage SI-NETs. The search included studies published between January 2010 and June 2025 and focused on human subjects, using keywords such as “small intestinal neuroendocrine tumor”, “metastasis”, “tumor grade”, and “treatment”. Results: We report the case of a 68-year-old man who presented with bowel obstruction. Imaging and surgical exploration revealed a jejunoileal SI-NET with extensive liver and peritoneal metastases, mesenteric fibrosis, and ascites. Histopathology confirmed a well-differentiated grade 2 tumor (Ki-67: 3%) positive for chromogranin A and CD56. Despite a low proliferative index, the tumor demonstrated aggressive clinical behavior. The patient underwent emergency enterectomy with ileostomy and was referred for further evaluation, including somatostatin receptor imaging and consideration for peptide receptor radionuclide therapy (PRRT). Conclusions: This case highlights the potential for aggressive progression in well-differentiated SI-NETs with low Ki-67 indices. Histological grade alone may not predict clinical behavior. Early diagnosis, comprehensive staging, and individualized multidisciplinary management—guided by functional imaging and receptor profiling—are critical to improving outcomes in advanced SI-NETs.

Background: Colorectal cancer (CRC) is a leading cause of cancer-related mortality worldwide, with Romania reporting among the highest rates in the European Union. Regional outcome data remain scarce. Methods: We performed a retrospective cohort study of 302 patients with surgically treated colorectal adenocarcinoma at a Romanian tertiary hospital between 2003 and 2005, with a median follow-up of 60 months. Survival was analyzed using Kaplan–Meier and Cox regression. Results: Radical resection with R0 margins was achieved in 72% of cases. The overall 5-year survival was 38%, with significantly lower outcomes in advanced stages. Independent predictors of poor prognosis included advanced stage, emergency surgery, incomplete resection, and older age. Conclusions: Survival outcomes in this Romanian cohort were substantially lower than those reported in Western Europe, reflecting the burden of late-stage presentation. These findings emphasize the urgent need for nationwide CRC screening programs and wider access to modern multimodal therapies.

Background/Objectives: Abdominal tumors can trigger acute, life-threatening complications, needing urgent care. Though often slow-growing, they may present suddenly with obstruction, bleeding, or organ compression. This article explores diagnostic challenges in such emergencies and presents a rare case of a giant mesenteric cyst. Methods: A PubMed search was conducted to review abdominal tumors in emergencies, focusing on mesenteric cysts. Results: A 37-year-old woman with no significant history presented with two weeks of diffuse abdominal pain and distension. Labs showed mild inflammation and low malignancy risk. Imaging revealed a large cystic mass compressing abdominal organs. Surgery found a 35 × 15 cm cyst from the mesenteric root extending into the pelvis and behind the stomach. Conclusions: Mesenteric cysts are rare with vague symptoms, needing high suspicion for diagnosis. Imaging helps, but large cysts often require surgery. Complete removal prevents recurrence, and bowel resection may be needed if vital structures are involved. Careful planning, teamwork, and follow-up ensure success.
