Accumulating evidence indicates that intratumoral heterogeneity contributes to the development of resistance to anticancer therapeutics. Fibroblasts, which are components of the paraneoplastic stroma, play a crucial role in the wound-healing process. Activated fibroblasts accumulate in the wound and are involved in many aspects of the tissue remodeling cascade that initiates the repair process and prevents further tissue damage. Read More

Inflammatory myofibroblastic tumor (IMT) is a distinctive neoplasm composed of myofibroblastic and fibroblastic spindle cells, accompanied by the inflammatory infiltration of plasma cells, lymphocytes and/or eosinophils. Epithelioid inflammatory myofibroblastic sarcoma (EIMS), which primarily consists of cells with a round or epithelioid morphology, is associated with a poor prognosis and rapid development of local recurrence, and has been recognized to be a variant of IMT. Diagnosis of EIMS is difficult owing to its close resemblance to malignant mesothelioma, anaplastic large cell lymphoma, gastrointestinal stromal tumor and other malignant diseases. Read More

Introduction: Inflammatory myofibroblastic tumor (IMT) is a rare mesenchymal tumor that involves various organs, but has a predilection for the urinary bladder in the genitourinary tract. Given that approximately half of all IMT cases have anaplastic lymphoma kinase (ALK) rearrangements, the ALK inhibitor crizotinib is suggested as a promising treatment for unresectable cases. No reports on neoadjuvant crizotinib therapy for locally advanced IMT of the bladder are available. Read More

Immunoglobulin G4 related disease (IgG4-RD) is a fibro-inflammatory disease of unknown etiology, characterized by lesions in the form of tumors, elevated serum IgG4 levels, plasma cells with significant IgG4 infiltration, accompanied by phlebitis obliterans and fibrosis. This disease usually has multiorgan disease, including pancreas, biliary tract, salivary glands, peri orbital tissues, kidneys, lungs, lymph nodes and retro peritoneum. IgG4-RD mainly affects men with a predominance of age by young adults until old age. Read More

Aims: Pseudosarcomatous myofibroblastic proliferations of the genitourinary tract have a debatable relationship with inflammatory myofibroblastic tumour (generally lacking ALK rearrangement); however, they share several overlapping features with nodular fasciitis of soft tissue. As rearrangement of the USP6 gene has been recently recognised as a recurrent alteration in soft tissue nodular fasciitis, and several other alternative gene fusions have been recently recognised in inflammatory myofibroblastic tumour, the aim of this study was to investigate whether USP6, ROS1 or ETV6 rearrangements were present in these lesions (12 cases).

Methods And Results: Fluorescence in-situ hybridisation analysis was performed by the use of bacterial artificial chromosome-derived break-apart probes against USP6, ROS1, and ETV6. Read More

The inflammatory myofibroblastic tumor (IMT) is a rare lesion of unclear etiology and variable clinical course, consisting of a proliferation of fibroblasts and myofibroblasts, mixed with inflammatory cells. Synonyms of IMT are inflammatory pseudotumor and plasma cell granuloma reflecting the alleged inflammatory nature attributed to this lesion, even though this heterogeneity in the disease denomination is probably involved in a dispersion of the literature data. Among primary pulmonary neoplasms, it represents the most frequent endobronchial tumor of childhood and beyond the lung it has been described mainly in the bladder, mediastinum and mesentery.

Introduction: Clear cell sarcoma of the kidney (CCSK) is childhood neoplasm with its own distinctive pattern of metastasis and may appear after a disease free interval of 5 years or more.

Materials And Methods: Histopathology and immunohistochemistry were available from the radical nephrectomy and the later partial cystectomy, which was performed after a seven disease-free interval.

Results: The pathologic features of the primary tumor were those of a classic CCSK with a monotypic pattern of uniform rounded to ovoid tumor cells with a background network of delicate blood vessels. Read More

Inflammatory myofibroblastic tumor (IMT) is a neoplasm of intermediate malignant potential that only rarely involves the gynecologic tract. Several cases of IMT arising in various locations including the lung, bladder, trachea, and breast in association with pregnancy have been reported in the literature, and 3 cases involving the placenta have been previously described. We report 2 cases of IMT identified in association with pregnancy; the first was an intrauterine mass delivered entirely separate from the placenta and fetus, and the second was an incidental mass identified within the placental parenchyma following delivery.

Inflammatory myofibroblastic tumors (IMT) are distinctive lesions of unknown etiology, composed of myofibroblastic spindle cells with an associated inflammatory background. They can occur in a wide age range and at all anatomic sites, but most frequently they can be observed in the lung (especially in pediatric cases), abdomen, or retroperitoneum.

Background: Metal-on-metal total hip prostheses (MoM-THR) have been shown to produce hypersensitivity reactions and fluid collection (pseudotumor) by the hip as well as high blood metal ions levels (BMILs).

Objectives: To evaluate the magnetic resonance imaging (MRI) signal-to-noise ratio (S/N) in selected body tissues around the hip of patients who underwent MoM hip replacement and to correlate to BMILs.

Methods: Sixty-one MRI hip examinations in 54 post-MoM-THR patients (18 males, 36 females, mean age 65 years) were retrospectively evaluated independently by two readers. Read More

Inflammatory myofibroblastic tumors rarely occur in the urinary bladder. These masses follow an indolent course, but due to their histologic similarities to more malignant types of bladder masses, they must be differentiated with immunohistochemical staining. Once diagnosed, the mainstay of treatment for these masses is surgical resection. Read More

Inflammatory myofibroblastic tumor (IMT), which expresses cyclooxygenase-2 (COX-2), can be effectively treated with COX-2 inhibitor. Here, we report a case of urinary bladder IMT in a 13-year-old boy.

Background: Inflammatory pseudotumour refers to a non-malignant tumour-like mass resulting from an inflammatory reaction that is composed of granulation tissue with leukocyte infiltration that commonly occurs in the paediatric or young adult population. These tumours occur more commonly in the lungs and the orbit but rarely does it affect the gastrointestinal tract. It poses a clinical diagnostic challenge since it is a benign condition than can mimic the malignant counterpart. Read More
