Clinicopathological characteristics and fertility preserving treatment of atypical polypoid adenomyoma.

Objective: Atypical polypoid adenomyoma (APA) is a rare benign tumor frequently diagnosed in young women that may coexist with or progress to atypical endometrial hyperplasia (EAH) or endometrioid endometrial carcinoma (EEC). This study aimed to investigate which subset of patients with APA are prone to concurrent or subsequent EAH or EEC, evaluate the necessity of progestin treatment in patients with APA only after achieving a complete response (CR) through hysteroscopic lesion resection, and assess the impact of concurrent APA on the fertility-preserving treatment of EAH or EEC. Methods: This retrospective single-center study analyzed 86 patients with APA treated at the Obstetrics and Gynecology Hospital of Fudan University between January 2010 and October 2021. Patients with EAH or EEC only who underwent fertility-preserving treatment during the same period were matched in a 2:1 ratio with patients with concurrent APA and EAH or EEC. The clinicopathological characteristics, treatments, and prognosis were analyzed. Results: The median patient age was 31 years (range 21-47 years). Among the 86 included patients, nine underwent total hysterectomy, 62 received conservative treatment, and the remaining 15 were lost to follow-up. A comparison of the 16 patients with APA only versus the 58 patients with APA and concurrent or subsequent EAH or EEC revealed that a homeostasis model assessment of insulin resistance (HOMA-IR) of > 2.2 (P = 0.047) and high-density lipoprotein (HDL) concentration of < 1.2 mmol/L (P = 0.028) were independent risk factors for EAH or EEC in patients with APA. Among the 17 patients with APA only who received conservative treatment and achieved a CR after hysteroscopic lesion resection, 13 received hormone treatment for a median duration of 6.3 months. The median follow-up time for these 17 patients was 49.0 months, during which no recurrence of APA was observed, but six patients developed endometrial hyperplastic diseases. Regarding the impact of concurrent APA on fertility-preserving treatment for EAH or EEC, the median time to achieve a CR was 24.0 weeks (95% confidence interval [CI]: 23.0-40.4) in the APA group and 26.0 weeks (95% CI: 24.3-32.3) in the non-APA group (P = 0.424). There were no significant differences between the two groups in the outcomes of fertility-preserving treatment. Conclusion: Patients with APA only may still develop endometrial hyperplastic diseases after complete resection of the lesion under hysteroscopy to achieve a CR, particularly those with a HOMA-IR of > 2.2 or HDL concentration of < 1.2 mmol/L. Concurrent APA did not affect the efficacy of fertility-preserving treatment in patients with EAH or EEC.

Follow-up imaging and surgical costs associated with different guidelines for management of incidentally detected gallbladder polyps.

RATIONALE AND OBJECTIVES: To compare follow-up imaging and surgical cost implications of the Society of Radiologists in Ultrasound (SRU) guidelines, 2017 and 2022 European (EUR) guidelines, 2020 Canadian Association of Radiologists (CAR) recommendations, and 2013 American College of Radiology (ACR) White Paper for managing incidentally detected gallbladder polyps. MATERIALS AND METHODS: 253 consecutive patients with gallbladder polyps identified on ultrasound were independently reviewed by three radiologists for polyp size and morphology. Electronic medical records were reviewed for patient demographics, cholecystectomy (if performed) pathological findings, or any subsequent diagnosis of gallbladder cancer. For each patient, the following were calculated for each of the 5 guidelines studied: 1) number of recommended follow-up ultrasounds based on initial presentation, 2) number of surgical consultations recommended based on initial presentation, 3) number of surgical consultations recommended based on growth, and 4) associated imaging and surgical costs. Interrater agreement was calculated. RESULTS: The SRU 2022 guidelines suggested significantly fewer follow-up ultrasounds and surgical consultations, leading to a cost reduction of 96.5 % and 96.7 % compared to European 2022 and 2017, respectively; 86.5 % compared to CAR; and 86.2 % compared to ACR guidelines. With SRU Recommendations, the majority of gallbladder polyps would be classified as extremely low risk (68.4 %), 30.8 % low risk, and 0.8 % indeterminate risk. In our cohort, a single case of gallbladder cancer was identified (26 mm) which would be recommended for surgical consult by all guidelines. CONCLUSION: The SRU 2022 guidelines can lead to significant savings for patients, health systems, and society, while reducing unnecessary medical interventions for managing incidentally detected gallbladder polyps.

Mantle cell lymphoma characterized by numerous diffuse polypoid lesions along the entire digestive tract: A case report.

Primary mantle cell lymphoma (MCL) in the gastrointestinal tract is rare, accounting for 4-9% of all reported cases of gastrointestinal non-Hodgkin lymphoma. Furthermore, involvement of the entire gastrointestinal tract in MCL is rare. The present report describes an example of MCL characterized by numerous diffuse polypoid lesions along the whole digestive tract. In particular, there was a focus on the endoscopic presentation of the digestive tract. The patient initially received a treatment regimen of rituximab combined with cyclophosphamide, doxorubicin, vincristine and prednisone. After two cycles of treatment, the regimen was changed to rituximab combined with etoposide, oxaliplatin and ifosfamide, with the addition of ibrutinib capsules. Patients with MCL have a poor prognosis; however, complete response can be achieved after treatment.

Giant Borderline Phyllodes Tumor Fungating Through the Skin as Fleshy Polypoid Outgrowths.

We present the case of a 52-year-old female with a giant phyllodes tumor (GPT), which was fungating through the skin that showed fleshy polypoid outgrowths. Histological analysis revealed stromal atypia, mitotic activity, and stromal overgrowth; however, the tumor border was well-defined, and malignant heterologous elements were not observed. Therefore, as some but not all malignant histological characteristics were present, we diagnosed the patient with borderline GPT. In cases of phyllodes tumor (PT) with the unique gross findings of fungation through the skin as fleshy polypoid outgrowths, caution is required for the subsequent course because even if the PT is graded as benign histologically, a malignant process can occur. Pathologists should note that the sampling of the collection site and the ambiguity of the histological grading of PT may affect the final diagnosis of GPT. It is also important to perform surgery with adequate preservation of the resected margins to control recurrence for patients with GPT.

The value of CT radiomics combined with deep transfer learning in predicting the nature of gallbladder polypoid lesions.

BACKGROUND: Computed tomography (CT) radiomics combined with deep transfer learning was used to identify cholesterol and adenomatous gallbladder polyps that have not been well evaluated before surgery. PURPOSE: To investigate the potential of various machine learning models, incorporating radiomics and deep transfer learning, in predicting the nature of cholesterol and adenomatous gallbladder polyps. MATERIAL AND METHODS: A retrospective analysis was conducted on clinical and imaging data from 100 patients with cholesterol or adenomatous polyps confirmed by surgery and pathology at our hospital between September 2015 and February 2023. Preoperative contrast-enhanced CT radiomics combined with deep learning features were utilized, and t-tests and least absolute shrinkage and selection operator (LASSO) cross-validation were employed for feature selection. Subsequently, 11 machine learning algorithms were utilized to construct prediction models, and the area under the ROC curve (AUC), accuracy, and F1 measure were used to assess model performance, which was validated in a validation group. RESULTS: The Logistic algorithm demonstrated the most effective prediction in identifying polyp properties based on 10 radiomics combined with deep learning features, achieving the highest AUC (0.85 in the validation group, 95% confidence interval = 0.68-1.0). In addition, the accuracy (0.83 in the validation group) and F1 measure (0.76 in the validation group) also indicated strong performance. CONCLUSION: The machine learning radiomics combined with deep learning model based on enhanced CT proves valuable in predicting the characteristics of cholesterol and adenomatous gallbladder polyps. This approach provides a more reliable basis for preoperative diagnosis and treatment of these conditions.

Discrimination between benign and malignant gallbladder lesions on enhanced CT imaging using radiomics.

BACKGROUND: Gallbladder cancer is a rare but aggressive malignancy that is often diagnosed at an advanced stage and is associated with poor outcomes. PURPOSE: To develop a radiomics model to discriminate between benign and malignant gallbladder lesions using enhanced computed tomography (CT) imaging. MATERIAL AND METHODS: All patients had a preoperative contrast-enhanced CT scan, which was independently analyzed by two radiologists. Regions of interest were manually delineated on portal venous phase images, and radiomics features were extracted. Feature selection was performed using mRMR and LASSO methods. The patients were randomly divided into training and test groups at a ratio of 7:3. Clinical and radiomics parameters were identified in the training group, three models were constructed, and the models' prediction accuracy and ability were evaluated using AUC and calibration curves. RESULTS: In the training group, the AUCs of the clinical model and radiomics model were 0.914 and 0.968, and that of the nomogram model was 0.980, respectively. There were statistically significant differences in diagnostic accuracy between nomograms and radiomics features (P <0.05). There was no significant difference in diagnostic accuracy between the nomograms and clinical features (P >0.05) or between the clinical features and radiomics features (P >0.05). In the testing group, the AUC of the clinical model and radiomics model were 0.904 and 0.941, and that of the nomogram model was 0.948, respectively. There was no significant difference in diagnostic accuracy between the three groups (P >0.05). CONCLUSION: It was suggested that radiomics analysis using enhanced CT imaging can effectively discriminate between benign and malignant gallbladder lesions.

Pictorial essay: improving diagnostic effectiveness of colorectal cancer at CT.

As the routine use for CT increases, there is an opportunity to increase the detection rate of unsuspected and asymptomatic colorectal cancers. This pictorial essay provides abundant examples of the typical morphologic appearances of colorectal cancer in the unprepared colorectum. Many examples of lesions that were missed in clinical practice are illustrated with lessons on how to avoid these errors. Atypical appearances of colorectal cancer are also illustrated. The overall aim is to increase the detection rate of colorectal cancer at routine CT.

Case report: An atypical case of uterine adenosarcoma with extensive bizarre stromal cells and amplification of MDM2.

Polypoid lesions in the uterus are very common. There are a lot of benign lesions and malignant tumor should be considered. Adenosarcoma, one of the differential diagnoses, is a rare mixed epithelial and mesenchymal tumor consisting of benign epithelial components and sarcoma stroma. Here, we present a case of atypical adenosarcoma that has never been reported. This tumor was composed of benign endometrial epithelium and hyperplastic stroma with extensive bizarre stromal cells. But the cleft-like spaces and papillary stomal fronds which were the typical histological images of adenosarcoma were absent. These stomal cells, including bizarre cells, were positive for vimentin, CD10, ER, PR, cyclin D1 and P16 but were immunonegative for caldesmon. Furthermore, this tumor harbored amplification of MDM2, as revealed by fluorescence in situ hybridization testing (FISH) and next-generation DNA sequencing (NGS).

Xanthogranuloma in the External Auditory Canal in Childhood, an Unexpected Lesion.

Pedunculated lesions in the external auditory canal present a broad differential diagnosis. It is crucial to rule out malignant neoplasms and consider the possibility of xanthogranulomas, which are very rare in this location. Management is determined by associated complications, and otolaryngologists must consider this for appropriate treatment.

Sinonasal Hamartoma and Chronic Laryngeal Edema Causing Severe Dyspnea.

Background: Sinonasal hamartomas, according to the 5th edition of the World Health Organisation classification of head and neck tumours are divided into respiratory epithelial adenomatoid hamartoma (REAH), seromucinous hamartoma and chondromesenchymal hamartoma. Seromucinous hamartoma are benign proliferations of small eosinophilic glands surrounded by fibrous stroma and cuboidal cells. Hamartomas of the nasal cavity and paranasal sinuses are rare entities, clinically presenting as sinonasal polyposis. Case Presentation: A 79- year-old female patient was referred to our emergency room due to severe dyspnea. Anterior rhinoscopy revealed unilateral greyish polypoid mass obstructing the middle, inferior and common nasal meatus. Systemic corticosteroids and oxygen therapy were administered under observation. Computerized tomographic imaging of the paranasal sinuses with contrast on all three planes showed an opacified polypoid mass in all meatus and the maxillary, anterior ethmoidal and sphenoidal sinus posteriorly extending to the choanae. On the coronal plane a widening of the olfactory clefts about 12 mm was described. FESS visualized that the polypoid mass originated from the posterior septum and extended to all meatus anteriorly and to the choanae posteriorly. The polypoid lesion was endoscopically completely excised. Histopathological analysis revealed a seromucinous hamartoma. Conclusion: Seromucinous hamartoma are rare benign tumors of the sinonasal region with potential of malignant alteration. Unfortunately, they share symptoms and clinical appearance with other benign conditions of the sinonasal region. Therefore, it is even more important to consider them as a differential diagnose.

Polypoid Lesion Segmentation Using YOLO-V8 Network in Wireless Video Capsule Endoscopy Images.

Gastrointestinal (GI) tract disorders are a significant public health issue. They are becoming more common and can cause serious health problems and high healthcare costs. Small bowel tumours (SBTs) and colorectal cancer (CRC) are both becoming more prevalent, especially among younger adults. Early detection and removal of polyps (precursors of malignancy) is essential for prevention. Wireless Capsule Endoscopy (WCE) is a procedure that utilises swallowable camera devices that capture images of the GI tract. Because WCE generates a large number of images, automated polyp segmentation is crucial. This paper reviews computer-aided approaches to polyp detection using WCE imagery and evaluates them using a dataset of labelled anomalies and findings. The study focuses on YOLO-V8, an improved deep learning model, for polyp segmentation and finds that it performs better than existing methods, achieving high precision and recall. The present study underscores the potential of automated detection systems in improving GI polyp identification.

Beyond typical histology of BAP1-inactivated melanocytoma.

BAP1-inactivated melanocytoma (BIM) is a novel subgroup of melanocytic neoplasm listed in the 5th edition of WHO classification of skin tumor. BIM is characterized by two molecular alterations, including a mitogenic driver mutation (usually BRAF gene) and the loss of function of BAP1, a tumor suppressor gene located on chromosome 3p21, which encodes for BRCA1-associated protein (BAP1). The latter represents a nuclear-localized deubiquitinase involved in several cellular processes including cell cycle regulation, chromatin remodeling, DNA damage response, differentiation, senescence and cell death. BIMs are histologically characterized by a population of large epithelioid melanocytes with well-demarcated cytoplasmic borders and copious eosinophilic cytoplasm, demonstrating loss of BAP1 nuclear expression by immunohistochemistry. Recently, we have published a series of 50 cases, extending the morphological spectrum of the neoplasm and highlighting some new microscopic features. In the current article, we focus on some new histological features, attempting to explain and link them to certain mechanisms of tumor development, including senescence, endoreplication, endocycling, asymmetric cytokinesis, entosis and others. In light of the morphological and molecular findings observed in BIM, we postulated that this entity unmasks a fine mechanism of tumor in which both clonal/stochastic and hierarchical model can be unified.

Primary gallbladder melanoma: A systematic review of literature.

Primary gallbladder melanoma (PGM) is a rare malignancy with only sporadic cases reported in the English literature. We performed a systematic review of the cases published in the PubMed, Science Direct and Google Scholar databases with the aim of describing the reported clinicopathologic features of PGM. Thirty-six articles reporting on 39 patients were reviewed. There was a male predominance, with 23 (64 %) of 36 patients being males. The mean age at presentation was 55 ±16 years. Pain in the right upper quadrant was reported in 20/27 (74 %). The average size of the tumor was 3.5 × 1.9 × 1.4 cm. Gallbladder calculi were reported in 7/27 (26 %). A cholecystectomy was performed in 34/38 (89.5 %). Grossly, the tumor mostly (96.5 %) had polypoid appearances and on microscopic examination, the tumor were predominantly comprised of epithelioid cells 12/17 (70.6 %). Mitotic figures and prominent nucleoli were reportedly found in 8/8 (100 %) and 3/3 (100 %) respectively. Junctional melanocytic components were present in 13/21 (61.9 %). Tumor cells were reportedly immunoreactive for S-100 and HMB-45 in all tested cases. Metastasis were reported in 25/36 (69.4 %), with lymph nodes being the most common site (n = 8), followed by brain (n = 6) and liver (n = 4) for metastasis. At a mean follow-up period of 19 +/- 3 months, 16 (48.5 %) of the 33 patients with available survival data were alive and 17/33 (51.5 %) were dead of disease. There is a lack of unified criteria for the diagnosis of PGM, and future studies should aim to resolve this.

Associations between vaginal microbiota and endometrial polypoid lesions in women of reproductive age: a cross-sectional study.

RESEARCH QUESTION: What are the different characteristics of vaginal microbial composition between patients with endometrial polypoid lesions and controls? DESIGN: This cohort study compared the pre-operative microbial compositions of vaginal samples in a cohort of 703 women with endometrial polypoid lesions [293 and 410 women diagnosed and not diagnosed with polyps pathologically (polyps group and not-polyps group, respectively] and 703 women in the control group. Bacterial abundance, diversity, differential taxa and microbial network structure were assessed using 16S rRNA gene sequencing. Predictive algorithms were used to determine the functional pathways of vaginal microbiota within the cohort. RESULTS: The control group exhibited higher relative abundance of Lactobacillus crispatus in comparison with the polypoid lesions group (P = 0.0427). Beta diversity of vaginal microbiota differed significantly between the groups (P < 0.05). Comparing the polyps group with the not-polyps group, Leptotrichia spp. and Cutibacterium spp. were more abundant in the polyps group, and Fannyhessea spp., Acinetobacter spp. and Achromobacter spp. were more abundant in the not-polyps group. The control group exhibited higher abundance of Bifidobacterium spp., Achromobacter spp. and Escherichia/Shigella spp. (false discovery rate < 0.05). Furthermore, the polyps group and not-polyps group displayed more complex co-occurrence networks compared with the control group. CONCLUSIONS: The results of this study provide compelling evidence supporting associations between vaginal microbiota and endometrial polypoid lesions, highlighting the potential relationship between a well-balanced vaginal microbial ecosystem and a healthy intrauterine environment.

Prolapsed Atypical Polypoid Adenomyoma-A Case Report and Literature Review.

Atypical polypoid adenomyoma (APAM) is a rare polypoid benign tumor of the uterus that causes irregular vaginal bleeding in women of reproductive age. It has the potential for malignant transformation, but it does not metastasize. APAM may coexist with endometrial hyperplasia and adenocarcinoma, usually leading to misdiagnosis. Histopathologically, it is a biphasic tumor, represented by the endometrioid glands with a complex histoarchitecture, with sometimes squamous morular metaplasia or cytologic atypia, interspersed with a fibromyomatous stroma. This tumor has a high incidence of recurrence. We present a very rare case of a 21-year-old patient, a virgin, without a significant medical history, with a bleeding mass occupying the vagina. The mass was excised using forceps, scissors, and a suture of the visible pedicle. After a four-year follow-up and no additional medical treatment, no relapse was observed. Given the risk of recurrence and progression, APAM might be treated via a hysterectomy in patients with no desire for pregnancy. Due to a lower recurrence rate, the conservative treatment of atypical polypoid adenomyoma performed via an operative hysteroscopy represents the best choice. Previously diagnosed in hysterectomy specimens, with the introduction of better-performing indirect imaging techniques, adenomyosis is a clinical entity that has the possibility of being diagnosed in the presurgical stage.

Reassessing the Role of Phonomicrosurgery and Smoking Status in the Management of Reinke's Edema.

OBJECTIVES: To elucidate recurrence patterns of Reinke's edema (RE) following phonomicrosurgery and compare current and former smokers' outcomes. METHODS: A retrospective chart review was performed for patients who underwent microflap excision for RE at our institution since 2008. Patient data were collected, including demographics, smoking history, and operative and voice outcomes during the available follow-up period. Descriptive statistics, student's t-tests, Chi-squared analyses, and Fischer's exact tests were used for the appropriate between-group comparisons utilizing JMP statistical software. RESULTS: Patients who quit smoking on the day of surgery or continued to smoke postoperatively were included in our group of current smokers (n = 56). Patients who quit smoking within the month of surgery or longer were included in our group of former smokers (n = 22). There was no significant difference in postoperative voice outcomes between groups. Eight patients in the entire cohort experienced recurrence during the available follow-up period. Fischer's exact test revealed no statistically significant association between smoking status and recurrence (two-tailed p > 0.05). The mean time to recurrence for current smokers who did recur was 69 and 54 months for former smokers. CONCLUSION: We report low overall recurrence rates after microflap excision of RE lesions compared with historical data, without any significant difference in recurrence or voice outcomes when comparing current and former smokers. Further prospective trials with larger sample sizes are warranted to guide the surgical management of RE patients and the implications of smoking status. LEVEL OF EVIDENCE: 3 Laryngoscope, 2023.

A Case Presentation of Three Polypoid Melanomas With Divergent Features.

Polypoid melanoma, a subtype of nodular melanoma, is classified as the most aggressive and deadly form of cutaneous melanoma. Its rapid vertical growth phase and a wide array of divergent features make clinical diagnosis extremely difficult. This report includes three cases of polypoid melanoma that were all originally thought to be other benign lesions or non-melanoma cancer. These cases feature the variability of the clinical presentation of polypoid melanomas while emphasizing the importance of an annual skin examination, complete lesion biopsies, and working with experienced dermatopathologists for the correct diagnosis and prompt treatment of these cancers. By sharing these cases and general information on polypoid melanoma, we aim to spread awareness of this rarer subtype of melanoma and highlight the importance of having a broad differential list when presented with suspicious lesions.

Rapidly growing extensive polypoid endometriosis after gonadotropin-releasing hormone agonist discontinuation: A case report.

BACKGROUND: Polypoid endometriosis (PEM) is a rare and unique type of endometriosis. To date, no article has provided a systematic report of this disease. The current article provides a complete report on rare PEM based on ultrasound, magnetic resonance imaging, intraoperative findings and postoperative pathology data. CASE SUMMARY: A 38-year-old female patient was admitted to our hospital after complaining of "vague pain in the right lower quadrant with an aggravated menstrual period for 8 mo". The patient underwent laparoscopic exploratory surgery on January 7, 2022. The postoperative pathology revealed extensive PEM. CONCLUSION: PEM is a type of endometriosis that is a benign disease but has biological properties similar to malignant tumours.

The typical polypoid adenomyoma is a special form of endometrial polyp: a case-controlled study with a large sample size.

PURPOSE: To investigate clinicopathological differences between typical endometrial polypoid adenomyomas (TPAs) and endometrial polyps (EPs) and to determine the risk factors and recurrence of TPA and further clarify the pathogenesis and treatment of TPA. METHODS: We reviewed the medical records of 488 women with TPA and 500 women with EP. Then, we analyzed the clinical features and manifestations, ultrasonic manifestations, hysteroscopic morphology, and pathological results. In addition, 360 cases of TPA and 367 cases of EP were followed up for 22-77 months and the risk factors TPA recurrence were assessed. RESULTS: We detected significant differences in age, menopausal status, body mass index (BMI), the number of pregnancies, and parity between the two groups (P < 0.05). Hysteroscopy revealed that the incidence of polyps > 3 cm in diameter and multiple polyps in the TPA group was significantly higher than that in the EP group (P < 0.01). In addition, the rate of recurrence in the TPA group was significantly higher than that in the EP group (P < 0.05). Over three pregnancies, menopause, curettage, and the application of polyp clamps were all identified as independent risk factors for the recurrence of TPA (P < 0.05). CONCLUSION: In addition to high estrogen levels, endometrial injury was identified as the main contributor to TPA pathogenesis. Hysteroscopic electrotomy was identified as the preferential treatment for TPA to avoid recurrence, especially in women with risk factors. Increasing the depth of ablation may prevent the recurrence of TPA more efficiently.

Colonic pedunculated polypoid vascular ectasia mimicking ileocolic intussusception: a rare case report.

Vascular ectasias are characterized by abnormal blood vessel enlargement and presumed to be caused by degenerative processes. About 3% of lower gastrointestinal bleeding is caused by it. On endoscopy, colonic arteriovenous malformations are frequently solitary, sizable, flat, or raised red lesions. Conversely, colonic vascular ectasia that manifests as pedunculated polypoid lesions are rare. Case presentation: A 45-year-old woman presented with hematochezia and abdominal pain. Abdominal ultrasound and Contrast enhanced computed tomography abdomen, both showed features of ileocolic intussusception. Intraoperatively, an intraluminal pedunculated polypoid growth extending up to the hepatic flexure of the colon was discovered. A right hemicolectomy was performed, removing the polypoid growth as well. After histopathological evaluation, a final diagnosis of colonic polypoid vascular ectasia was made. Clinical discussion: Gastrointestinal bleeding is the common initial manifestation of vascular ectasia, while some individuals may continue to be asymptomatic. According to a study from July 2022, vascular ectasia that manifests as polypoid growth is an uncommon phenomenon that has only been documented in 17 other cases. An intussusception may have a polypoid vascular ectasia as its lead point. Conversely, a large polypoid vascular ectasia may have radiographic characteristics that resemble an intussusception. Conclusion: Large colonic vascular ectasia, which tends to enlarge over time, can occasionally be misinterpreted as an intussusception due to comparable radiological appearances. In the event that a polypoid colonic vascular ectasia is misidentified for intussusception, the surgical team must be ready to adjust the treatment protocol as needed.
