Incidental findings during donor liver assessment: Single center experience.

Intraoperative consultation of donor liver is an important part of transplant evaluation and determination of liver eligibility. In this study, we describe incidental pathologic findings discovered during the pretransplant evaluation of liver donors in our Institution from 1/2010 to 12/2022. During this 13-year period 369 intraoperative consultations from 262 liver donors were performed. Of those cases, incidental findings were identified in 22 cases (5.9 %) from 19 donors (7.3 %); two donors had more than one lesion. The median age of this subset of patients was 53 years (range: 18-70) and females predominated (63 %). Sixteen of the donors had abnormal findings in the liver: 6 bile duct hamartoma (BDH), 5 hyalinized nodule with Histoplasma capsulatum, 5 focal nodular hyperplasia (FNH), 2 bile duct adenomas (BDA), 1 biliary cyst and 1 hemangioma. One donor had both FNH and a BDH. One BDH and 1 BDA case was misdiagnosed as malignancy during the frozen section evaluation. Three donors had extrahepatic pathologies: a pancreatic tail schwannoma, a low-grade appendiceal mucinous neoplasm, and a lymph node with metastatic endometrial endometrioid adenocarcinoma. Of the 19 livers, the final organ disposition was available for 9: 6 were transplanted (67 %) and 3 were discarded (33 %). Two of the 3 discarded organs were misdiagnosed BDH and BDA cases, and one was incorrectly reported as having 90 % microvesicular steatosis during the frozen assessment. We present the clinicopathologic characteristics of liver donors with incidental findings during the pre-transplant evaluation which could lead to unwarranted graft dismissal if misdiagnosed. Additionally, incidental fungal infections can have implications for immunosuppressive therapy and the decision to use or reject the graft.

Metabolic Interplay in the Tumor Microenvironment: Implications for Immune Function and Anticancer Response.

Malignant tumors exhibit rapid growth and high metabolic rates, similar to embryonic stem cells, and depend on aerobic glycolysis, known as the "Warburg effect". This understanding has enabled the use of radiolabeled glucose analogs in tumor staging and therapeutic response assessment via PET scans. Traditional treatments like chemotherapy and radiotherapy target rapidly dividing cells, causing significant toxicity. Despite immunotherapy's impact on solid tumor treatment, gaps remain, leading to research on cancer cell evasion of immune response and immune tolerance induction via interactions with the tumor microenvironment (TME). The TME, consisting of immune cells, fibroblasts, vessels, and the extracellular matrix, regulates tumor progression and therapy responses. TME-targeted therapies aim to transform this environment from supporting tumor growth to impeding it and fostering an effective immune response. This review examines the metabolic disparities between immune cells and cancer cells, their impact on immune function and therapeutic targeting, the TME components, and the complex interplay between cancer cells and nontumoral cells. The success of TME-targeted therapies highlights their potential to achieve better cancer control or even a cure.

Successful treatment of malakoplakia of the liver and skin in a pediatric liver transplant patient.

BACKGROUND: Malakoplakia occurs uncommonly at any age, but pediatric reports are exceptionally limited. Malakoplakia appears primarily in the urinary tract, although involvement of essentially all organs has been reported, cutaneous malakoplakia is very uncommon and liver involvement is the rarest. METHOD: We report the first pediatric case of concurrent hepatic and cutaneous malakoplakia in a pediatric liver transplant recipient. We also provide a literature review for cutaneous malakoplakia cases in children. RESULT: A 16-year-old male received a deceased-donor liver transplant for autoimmune hepatitis, present with the persistence of the liver mass of unknown etiology and cutaneous plaque-like lesions around the surgical scar. Core biopsies taken from the skin and abdominal wall lesions demonstrated histiocytes containing Michaelis-Gutmann bodies (MGB) revealing the diagnosis. The patient successfully was treated with antibiotics alone for 9 months without surgical intervention or a decrease in immunosuppressive therapy. CONCLUSION: This case demonstrates the need to include malakoplakia in the differential diagnosis of mass-forming lesions after solid transplantation and increase awareness of this very rare entity in pediatrics.

A Consensus Diagnosis Utilizing Surface KI-67 Expression as an Ancillary Marker in Low-Grade Dysplasia Helps Identify Patients at High Risk of Progression to High-Grade Dysplasia and Esophaegal Adenocarcinoma.

Esophageal adenocarcinoma (EAC) develops in a step-wise manner, from low-grade dysplasia (LGD) to high-grade dysplasia (HGD), and ultimately to invasive EAC. However, there remains diagnostic uncertainty about LGD and its risk of progression to HGD/EAC. The aim is to investigate the role of Ki-67, immune-histochemical marker of proliferation, surface expression in patients with confirmed LGD, and risk stratify progression to HGD/EAC. A retrospective cohort study was conducted. Patients with confirmed LGD and indefinite for dysplasia (IND), with a mean follow-up of ≥1 year, were included. Pathology specimens were stained for Ki-67 and analyzed for evidence of surface expression. Our results reveal that 29% of patients with confirmed LGD who stained positive with Ki-67 progressed to HGD/EAC as opposed to none (0%) of the patients who stained negative, a statistically significant result (P = 0.003). Similarly, specimens from patients with IND were stained and analyzed revealing a nonsignificant trend toward a higher rate of progression for Ki-67 positive cases versus Ki-67 negative, 30% versus 21%, respectively. Ki-67 expression by itself can identify patients with LGD at a high risk of progression.

Persistent indefinite for dysplasia in Barrett's esophagus is a risk factor for dysplastic progression to low-grade dysplasia.

Patients with Barrett's esophagus (BE) are at increased risk of esophageal adenocarcinoma (EAC). The risk is largely based on the degree of dysplasia. Dysplasia cannot always be differentiated from inflammatory changes, and therefore may be classified as indefinite for dysplasia (IND). The risk of progressive dysplasia in patients with IND is unclear. Our aim is to characterize the risk of progression in US veterans with BE-IND. We performed a single-center retrospective cohort study of patients with BE-IND between 2006 and 2016. All IND was diagnosed by consensus conference with an expert gastrointestinal (GI) pathologist or review by an expert GI pathologist and persistence was defined as IND present on subsequent endoscopic biopsy. The primary outcome was the incidence rate of high-grade dysplasia (HGD)/EAC. Secondary outcomes included any progression including incident low-grade dysplasia (LGD), any prevalent dysplasia and risk factors for dysplastic progression, namely persistent IND. Risk factors for progression were assessed using univariate and multivariate analysis with logistic regression. Among 107 patients with BE-IND, there were no incident cases of HGD/EAC. Twenty patients (18.7%) developed incident LGD during a median follow-up of 2.39 years (interquartile range, 1.13-5.17). The annual rate of progression to LGD was 5.95 per 100 patient-years (95% CI, 3.73-9.02). Prevalent dysplasia was common (9.3%). Eight patients had prevalent LGD, one patient had prevalent HGD and one patient had prevalent EAC. Twenty-eight patients (30.1%) were found to have persistent IND. Among those with persistent IND, 10 (36%) patients progressed to LGD (none to HGD/EAC). The progression rate to LGD for patients with persistent IND was 7.86 (95% CI, 3.99-14.02) cases per 100 patient-years versus 4.78 (95% CI, 2.48-8.52) for nonpersistent IND (P = 0.036). The odds ratio for progression to LGD in persistent IND was 3.06 (95% CI, 1.08-8.64). In multivariate analysis adjusting for age, smoking history, presence of hiatal hernia and BMI > 30, persistent IND remained significant (OR 3.23; 95% CI, 1.04-9.98). Regression to nondysplastic BE was very common. Seventy-one (61%) patients developed complete and sustained regression of all dysplastic changes at last follow-up. Persistent IND, present in one-third of patients with IND, is an independent risk factor for progression to LGD. Although no patients in this cohort developed HGD/EAC, prevalent dysplasia was common (9.3%). Taken together, patients with IND should receive close surveillance for both prevalent and incident dysplasia especially if IND is persistent.

Effect of blackberry juice (Rubus fruticosus L.) on anxiety-like behaviour in Wistar rats.

The present study evaluated the effects of blackberry juice that is rich in different concentrations of anthocyanins and polyphenols (2.6 mg/kg anthocyanins, 14.57 mg/kg polyphenols; 5.83 mg/kg anthocyanins, 27.10 mg/kg polyphenols; 10.57 mg/kg anthocyanins, 38.40 mg/kg polyphenols) on anxiety-like behaviour in Wistar rats. The rats were treated with blackberry juice for 21 days and then tested in the elevated plus maze, locomotor activity test and forced swim test. The results were compared with a reference anxiolytic drug diazepam (2.0 mg/kg) and vehicle (8.7 ml/kg). The intermediate dose of blackberry juice exerted an anxiolytic-like effect that was similar to diazepam, without affecting locomotive activity. The low and high doses of blackberry juice exerted no significant effects on anxiety-like behaviour compared with vehicle. In the forced swim test, both the high and intermediate doses of blackberry juice reduced total immobility time, suggesting a protective effect against behavioural changes that are induced by acute stress. These findings suggest a potential therapeutic effect of blackberry juice on anxiety that is associated with a stressful event.

Risk factors associated with gastric cancer in Mexico: education, breakfast and chili.

BACKGROUND AND AIM: the aim of the study was to use a validated questionnaire to identify factors associated with the development of gastric cancer (GC) in the Mexican population. METHODS: the study included cases and controls that were paired by sex and ± 10 years of age at diagnosis. In relation to cases, 46 patients with a confirmed histopathological diagnosis of adenocarcinoma-type GC, as reported in the hospital records, were selected, and 46 blood bank donors from the same hospital were included as controls. The previously validated Questionnaire to Find Factors Associated with Gastric Cancer (QUFA-GC©) was used to collect data. Odds ratio (OR) and 95% confidence interval (IC) were estimated via univariate analysis (paired OR). Multivariate analysis was performed by logistic regression. A decision tree was constructed using the J48 algorithm. RESULTS: an association was found by univariate analysis between GC risk and a lack of formal education, having smoked for ≥ 10 years, eating rapidly, consuming very hot food and drinks, a non-suitable breakfast within two hours of waking, pickled food and capsaicin. In contrast, a protective association against GC was found with taking recreational exercise and consuming fresh fruit and vegetables. No association was found between the development of GC and having an income that reflected poverty, using a refrigerator, perception of the omission of breakfast and time period of alcoholism. In the final multivariate analysis model, having no formal education (OR = 17.47, 95% CI = 5.17-76.69), consuming a non-suitable breakfast within two hours of waking (OR = 8.99, 95% CI = 2.85-35.50) and the consumption of capsaicin ˃ 29.9 mg capsaicin per day (OR = 3.77, 95% CI = 1.21-13.11) were factors associated with GC. CONCLUSIONS: an association was found by multivariate analysis between the presence of GC and education, type of breakfast and the consumption of capsaicin. These variables are susceptible to intervention and can be identified via the QUFA-GC

Ischemic Gastritis: A Multicenter Case Series of a Rare Clinical Entity and a Review of the Literature.

GOALS: To report a case series of ischemic gastritis and discuss its etiology, management, and associated mortality according to our results and the published English literature. BACKGROUND: Ischemic gastritis is rare, given the rich blood supply of the stomach. It has been reported in isolated case reports and small case series. Most cases are vascular in origin and associated with a high mortality. STUDY: Pathology databases from 3 hospitals affiliated with the University of Minnesota Medical School were searched for cases of ischemic gastritis in the last 10 years. Patients' demographics, clinical course, and 1-month and 1-year mortalities were collected from electronic medical records. RESULTS: A total of 12 patients were identified (age range, 32.1 to 83.2), the largest series reported to date. The presenting symptom was gastrointestinal bleeding (8), abdominal pain (2), nausea (1), and symptomatic anemia (1). The etiology included postinterventional radiology embolization (2), hemodynamic changes in the setting of celiac axis stenosis (2), vasculitis (1), systemic hypotension (1), and unknown (6). Treatment included steroid therapy, revascularization by interventional radiology, surgery, or supportive treatment. Thirty-day and 1-year mortalities were 33% and 41%, respectively. CONCLUSIONS: Ischemic gastritis is rare, but associated with a high mortality. Evaluation for treatable etiologies should be sought and corrected if present.

Fatal acute cardiac vasculopathy during cisplatin-gemcitabine-bevacizumab (CGB) chemotherapy for advanced urothelial carcinoma.

BACKGROUND: Bladder cancer (BC) accounts for ∼14,680 deaths annually in the U.S. The prognosis of advanced disease remains dismal with current therapies. A phase III intergroup trial for metastatic BC adding bevacizumab to first-line cisplatin-gemcitabine chemotherapy (GCB regimen) is currently ongoing. We report the clinical-pathologic findings of a patient who developed fatal acute cardiac microvascular toxicity while receiving this regimen. CASE REPORT: A 66 year old man consulted for epigastric pain, nausea, intermittent diarrhea and lightheadedness two weeks after receiving the first cycle of GCB chemotherapy for metastatic BC. Physical evaluation, laboratory studies and electrocardiogram (EKG) were within normal limits except for marked thrombocytopenia that was attributed to his recent chemotherapy. The patient was admitted for observation, rehydrated and started on a proton pump inhibitor. The following day, however, he experienced sudden severe chest and right upper quadrant pain. EKG showed tachycardia, ST elevations in leads V2 and V3, laboratory analyses revealed marked elevation of cardiac troponin I, and an echocardiogram showed a markedly reduced ejection fraction of 10-20%, consistent with rapidly progressive cardiogenic shock. Emergent cardiac catheterization showed no significant coronary artery disease. Sepsis work-up was negative. He became progressively hypotensive, developed multi-organ failure, and died 48 h after admission. Postmortem examination showed diffuse microvasculopathy and changes due to global hypoperfusion of 12-48 h evolution. CONCLUSIONS: We present the first case of acute, fatal cardiac failure due to microvasculopathy most consistent with bevacizumab-associated toxicity. The findings are discussed in light of the existing literature.

Morphometric measurement of submucosal thickness in areas of fat deposition in the terminal ileum and colonic sections, with correlation with body mass index, weight and age: a male autopsy study.

AIMS: An increased amount of submucosal (SM) fat in the colon on imaging is considered to be characteristic of inflammatory bowel disease (IBD); however, a recent study in patients without IBD reported a correlation between colonic SM fat deposition and body weight (BW). The aim of this study was to perform a morphometric investigation of SM thickness in areas of fat deposition in the terminal ileum (TI), ileocaecal valve (ICV), and colonic sections, to determine whether there are variations by site, and whether it shows a correlation with BW, body mass index (BMI), or age. METHODS AND RESULTS: Representative samples of TI, ICV and colonic sections were collected prospectively from 115 autopsy cases without IBD. All of the study subjects were male (Veterans Hospital). SM thickness was measured in areas of fat deposition. Correlation analysis was performed between SM thickness and BW, BMI, and age. Fat deposition was common; however, with the exception of the ICV, it was neither consistent nor prominent, and it did not show a statistical correlation with BW, BMI, or age. CONCLUSIONS: SM fat deposition is common but not uniform or conspicuous in the TI or colon. In contrast to extravisceral intra-abdominal fat, it does not show a correlation with BW or BMI, and is not associated with ageing. As all study subjects were male, gender-dependent variability cannot be excluded.

Cutaneous basal cell carcinosarcoma: case report and literature review.

Carcinosarcomas are malignant neoplasms with biphasic carcinomatous and sarcomatous or sarcoma-like components. In general, the sarcomatous component is accepted to be the result of divergent mesenchymal differentiation of the epithelial component. Although well characterized in some anatomic locations (e.g. uterus, upper aerodigestive tract and lung), carcinosarcomas of the skin are rare. Reported epithelial components include squamous, adnexal, neuroendocrine and basaloid. Including this case, only 47 cases of primary cutaneous basal cell carcinosarcoma have been reported in the literature to date. We performed an extensive immunophenotypic evaluation in our case, which confirmed the previously reported coexpression of p53 in both components, and revealed a hitherto unreported coexpression of p16 and p63. Additionally, this report reviews the clinical, pathologic, immunophenotypic characteristics and outcomes of the basal cell carcinosarcomas reported in the literature, in order to emphasize the overall uniform characteristics and clinical behavior of this neoplasm.

Application of time series discretization using evolutionary programming for classification of precancerous cervical lesions.

In this work, we present a novel application of time series discretization using evolutionary programming for the classification of precancerous cervical lesions. The approach optimizes the number of intervals in which the length and amplitude of the time series should be compressed, preserving the important information for classification purposes. Using evolutionary programming, the search for a good discretization scheme is guided by a cost function which considers three criteria: the entropy regarding the classification, the complexity measured as the number of different strings needed to represent the complete data set, and the compression rate assessed as the length of the discrete representation. This discretization approach is evaluated using a time series data based on temporal patterns observed during a classical test used in cervical cancer detection; the classification accuracy reached by our method is compared with the well-known times series discretization algorithm SAX and the dimensionality reduction method PCA. Statistical analysis of the classification accuracy shows that the discrete representation is as efficient as the complete raw representation for the present application, reducing the dimensionality of the time series length by 97%. This representation is also very competitive in terms of classification accuracy when compared with similar approaches.

Immunophenotypic analysis of angiomyolipoma with epithelial cysts, comparison to mixed epithelial and stromal tumors and epithelial and stromal elements of normal kidney and ovaries.

Angiomyolipoma with epithelial cysts (AMLEC) is a rare variant of renal angiomyolipoma (AML). It is characterized by a conventional AML component admixed with epithelial cysts within an "ovarian-like" stroma. Mixed epithelial and stromal tumor (MEST) is another renal neoplasm featuring epithelial cysts and "ovarian-like" stroma. While there is consensus that in MEST the epithelial and stromal components are neoplastic, in AMLEC it has been hypothesized that the epithelial component may represent renal tubular entrapment or ovarian-like transdifferentiation of tumor cells. The aim of this study was to compare the immunophenotypes of the epithelial-stromal components of AMLEC and MEST, with normal kidney and ovary to provide additional insights into the pathogenesis and relationships of these entities. In this study, we analyzed eight cases of AMLEC and 14 cases of MEST from 2003 to 2023. We used tissue microarrays, full sections, or unstained slides with an immunohistochemical panel including renal and ovarian markers: SF1, ER, PR, AR, PAX8, WT1, GATA3, CA-IX, p16, inhibin A, and BCL2. We compared these cases with ten non-neoplastic ovary and kidney samples. Our findings indicate that the epithelial component of AMLEC and MEST resembles hormone receptor positive renal tubular epithelium (AR + /ER - /PR -). AMLEC's stromal component resembled hormone receptor positive renal stroma, while MEST's resembled ovarian stroma, supporting mullerian transdifferentiation. Our study showed that the epithelial and stromal components of AMLEC and MEST are immunophenotypically different and also differ from normal tissues. Our findings suggest that in AMLEC, the epithelial-stromal component represents a hormonally driven proliferation of non-neoplastic renal elements within a dysregulated tumor microenvironment.

Painful Granulomatous Hashimoto Thyroiditis Uncovered Systemic Histoplasmosis.

Background. Granulomatous thyroiditis is usually viral and very rarely due to fungal infection. Fungal thyroiditis affects the severely immunocompromised and only rarely immunocompetent individuals. Case report. A 32-year-old man with known Hashimoto thyroiditis was consulted for a 1-week history of neck pain, dysphagia, cough, asthenia, loss of appetite, and night sweats. Imaging showed an enlarged right thyroid lobe. Laboratory studies confirmed hypothyroidism. He underwent a thyroid lobectomy. Microscopic examination showed granulomas in a background of Hashimoto thyroiditis. Silver stain revealed numerous yeasts consistent with Histoplasma. Subsequent serology was also positive. Further evaluations were negative for acquired or constitutional immunodeficiencies. He was started on oral itraconazole with resolution of all constitutional symptoms. Conclusions. We report a second case of concurrent Hashimoto and Histoplasma thyroiditis in an immunocompetent patient. Systemic manifestations of fungal infection are confounded by systemic symptoms of thyroid dysfunction. Fungal thyroiditis is a manifestation of systemic fungal infection requiring prolonged systemic therapy to prevent complications or fatal outcomes.

Metastatic germ cell tumors in serous cavities and cerebrospinal fluid: A single-center experience.

BACKGROUND: Metastatic germ cell tumors (GCTs) involving body cavity effusions and cerebrospinal fluid (CSF) are rare. Diagnosis is challenging because of limited morphological and clinicopathological information in the literature. METHODS: A database search of our institution from 1990 to 2024 identified 27 cases of metastatic GCTs, comprising five pediatric and 22 adolescent and adult patients, in serous cavities or the CSF, including peritoneal (15), pleural (nine), CSF (two), and pericardial (one) fluid. RESULTS: The most common primary site was the testis (n = 10), followed by the ovaries (n = 7), mediastinum (n = 4), retroperitoneum (n = 3), pineal gland (n = 2), and sacrum/coccyx (n = 1). The primary tumors in 14 patients were mixed GCTs (six with a seminoma component), followed by immature teratomas (six), yolk sac tumors (three), embryonal carcinomas (two), pure seminomas (one), and postpubertal teratomas (one). The median interval between primary tumor diagnosis and diagnosis of fluid positivity was 7 months (range: 0-134 months). In nine cases, the malignant fluid was diagnosed simultaneously with or within 1 month of the primary tumor. GCT subtyping was performed on 23 of the 27 cytological specimens. Twenty-four patients (89%) also had metastases to other sites. Thirteen patients died of the disease (48%), with a median survival time of 4 months. CONCLUSIONS: Metastatic GCTs in serous effusions and CSF are often associated with disseminated disease and poor prognosis. Subtyping can be performed by cytomorphology combined with immunohistochemistry.

Characterizing drought prediction with deep learning: A literature review.

Drought prediction is a complex phenomenon that impacts human activities and the environment. For this reason, predicting its behavior is crucial to mitigating such effects. Deep learning techniques are emerging as a powerful tool for this task. The main goal of this work is to review the state-of-the-art for characterizing the deep learning techniques used in the drought prediction task. The results suggest that the most widely used climate indexes were the Standardized Precipitation Index (SPI) and the Standardized Precipitation Evapotranspiration Index (SPEI). Regarding the multispectral index, the Normalized Difference Vegetation Index (NDVI) is the indicator most utilized. On the other hand, countries with a higher production of scientific knowledge in this area are located in Asia and Oceania; meanwhile, America and Africa are the regions with few publications. Concerning deep learning methods, the Long-Short Term Memory network (LSTM) is the algorithm most implemented for this task, either implemented canonically or together with other deep learning techniques (hybrid methods). In conclusion, this review reveals a need for more scientific knowledge about drought prediction using multispectral indices and deep learning techniques in America and Africa; therefore, it is an opportunity to characterize the phenomenon in developing countries.

Differential Diagnosis of Cystic Lesions of the Spleen: A Review of Clinical, Imaging and Pathological Findings.

Cystic lesions of the spleen are being noticed with increased frequency as "incidentalomas" during imaging work-up for unrelated causes. As a group, these lesions encompass pure cystic and mixed cystic and solid, benign and malignant processes that in general require a tissue sample for definitive diagnosis. In this review, we will describe the differential diagnosis of cystic lesions of the spleen, highlighting key imaging, clinical and pathologic findings.

Fatal eosinophilic myocarditis and submassive hepatic necrosis in lamotrigine induced DRESS syndrome.

Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) syndrome is a rare but severe and sometimes fatal adverse drug reaction that is known to occur with a number of antiepileptic drugs. It often follows a prolonged clinical course, which can worsen even after discontinuing the causative drug and administering steroid treatment. Failure to promptly identify the delayed involvement of vital organs, such as the heart and liver, may result in irreversible organ failure and death. We report a case of a presumed sudden death of a young woman who had a documented history of a protracted intermittent hypersensitivity reaction to lamotrigine. Postmortem examination revealed the presence of eosinophilic myocarditis and submassive hepatic necrosis diagnostic of fatal DRESS syndrome that progressed despite early discontinuation of the medication and improvement of dermatologic and hematologic symptoms following steroid therapy.

Jejunal Intussusception Secondary to a Large Inflammatory Fibroid Polyp: A Case Report and Discussion of Differential Diagnosis.

Inflammatory fibroid polyp (IFP), initially considered a reactive process, is now recognized as a benign mesenchymal neoplasm of the gastrointestinal tract. We report a case of a 68-year-old woman with medically refractory Crohn disease that presented with intussusception requiring surgical intervention. The resection revealed a jejunal mass consisting of a submucosal proliferation of bland spindle cells in a fibrous stroma infiltrated by numerous eosinophils. By immunohistochemistry, the lesion was positive for vimentin and negative for desmin, smooth muscle actin (SMA), S-100, CD117, DOG1, ALK (D5F3), Melan-A, HMB-45, CD34, and STAT6. Ki-67 proliferative index was low (<1%). The mass was classified as IFP by its characteristic morphology and associated eosinophilia. IFP should be considered in the differential diagnosis of adults with intussusception or bowel obstruction. Definitive treatment typically requires surgical resection of the involved bowel segment.
