BACKGROUND: Several reports on immunoglobulin (Ig)G4-related disease (IgG4-RD) with gastrointestinal involvement (IgG4-related gastrointestinal disease; IgG4-GID) have been published, although this entity has not been fully established clinicopathologically. Thus, we carried out a multicenter survey. METHODS: Patients with possible IgG4-GID who underwent resection were collected. Histologic slides were reevaluated, and eight cases with diffuse lymphoplasmacytic infiltration but without numerous neutrophils, granulations or epithelioid granulomas were further analyzed...

INTRODUCTION: Although appendicitis is a common disease, appendicitis concurrent with liver abscesses and sessile serrated adenoma/polyp (SSA/P) is rare. PRESENTATION OF CASE: A 69-year-old man presented with symptoms of abdominal pain and fever. Computed tomography (CT) revealed multiple liver abscesses and an enlarged appendix with a pseudotumoral appearance, which suggested acute appendicitis. In the emergency operation, ileocecal resection was performed for the perforated appendicitis with an inflammatory mass in the ileocecum...

A 79-year-old male presented to our hospital with abdominal discomfort and was diagnosed with mass-forming pancreatitis. During follow-up, pancreatic stones and a hepatic mass with peripheral bile duct dilation were discovered. Serum IgG4 level was elevated, and a liver tumor biopsy revealed numerous IgG4-positive plasma cells and fibrosis. Chronic pancreatitis with the suspected involvement of autoimmune pancreatitis (AIP) and IgG4-related hepatic inflammatory pseudotumor (IgG4-HIP) was diagnosed. Therefore, a steroid treatment was initiated...

IgG4-related sclerosing disease, which now encompasses diverse organ-related disorders with various prior eponymic designations, may also present with solitary or multifocal lymph node enlargement. This review considers the histopathologic features of IgG4 lymphadenopathy (IgG4LAD), which has been subdivided by Cheuk & Chan into 5 microscopic subtypes. Those include variants that are typified by multicentric Castleman disease (MCD)-like changes, follicular hyperplasia, interfollicular lymphoplasmacytic proliferation, progressive transformation of germinal centers, and formation of inflammatory pseudotumor (IPT)-like lesions...

We report a case of vanishing tumor considered as inflammatory pseudotumor (IPT) found in the liver after living donor liver transplantation (LDLT) from a hepatitis B virus surface antigen-positive donor. The radiological findings were similar to those of hepatocellular carcinoma (HCC). However, the tumor disappeared completely within several months and was suggested to have been an IPT. IPT is known to be associated with biliary duct operation or biliary infection, and it can show various enhancement patterns in radiological studies, sometimes resembling HCC...

We report a case of inflammatory pseudotumor of the ureter. An 81-year-old man who had an operation of pelvic exenteration with ileal conduit presented with right flank pain. Computed tomography revealed a 16 mm mass of the right ureter with right hydronephrosis and renal atrophy. The mass increased in size during follow up. Right nephroureterectomy was performed with suspicion of ureteral cancer. Histopathological finding showed an inflammatory pseudotumor. No obvious recurrence has been observed for 33 months after the surgery...

Early diagnosis is pivotal for prognosis of lung cancer patients. Positron emission tomography/computed tomography (PET-CT) is a useful method for human cancer diagnosis. In this study, we aimed to explore the false positive diagnosis of PET-CT in lung cancerIn total, 754 patients diagnosed with lung cancer via PET-CT were retrospectively collected in this study. Histopathological detection served as gold standard. The diagnostic accuracy of PET-CT was defined as the proportion of lung cancer cases confirmed by pathological diagnosis in the study subjects, and the percentages of misdiagnosed cases represented the false positive diagnosis of PET-CT...

Inflammatory myofibroblastic tumor, also known as inflammatory pseudotumor and plasma cell granuloma, is a tumor that occurs most often in the lungs, abdomen, skin, soft tissue, genital system, and mediastinal. Before surgery, the diagnosis is difficult to establish because of its diverse manifestations. In the head and neck, manifestation is rare and may occur in the upper respiratory tract, soft tissues, orbits, and skull base. This article aims to report a rare manifestation of the disease in the face, highlighting the importance of a correct diagnosis to determine the most appropriate form of treatment, in male patient, leucoderma, 22 years old, with complain of a painless unilateral growth in the left cheek, beginning 2 months before and with progressive growth...

Inflammatory pseudotumor of the liver is a rare benign tumor that can be confused with malignant tumors of the liver. It is usually diagnosed after pathologic evaluation of the resected lesion. If a mass lesion in the liver is suspicious for malignancy on radiologic evaluation then surgical resection is planned for suitable patients rather than a biopsy. Inflammatory pseudotumors are similar to malignant tumors on macroscopic assessment, but microscopically they are characterized by the presence of inflammatory cells...

A 77-year-old Japanese woman presented to an ophthalmologist with an erythematous swollen upper eyelid and diplopia which was initially diagnosed to be idiopathic dacryoadenitis on the basis of a histological evaluation of an orbital mass that was in remission following a 3.5-month period of systemic corticosteroid therapy. She subsequently developed respiratory symptoms, and was finally diagnosed with systemic granulomatosis with polyangiitis (GPA) based on the clinical and histological features. She was successfully treated with corticosteroids and azathioprine...

Pseudotumoral cerebellitis in childhood is an uncommon presentation of cerebellitis mimicking a brain tumor. It often follows an inflammatory or infectious event, particularly due to varicella virus. Patients could have a wide clinical spectrum on presentation. Some patients may be asymptomatic or present at most with mild cerebellar signs, whereas others may suffer severe forms with brainstem involvement and severe intracranial hypertension mimicking tumor warranting surgical intervention. Imaging techniques especially multimodal magnetic resonance imaging represent an interesting tool to differentiate between posterior fossa tumors and acute cerebellitis...
