Abstract
BACKGROUND Inflammatory pseudotumor-like follicular dendritic cell sarcoma (IPT-like FDCS) is often associated with Epstein-Barr (EB) virus infection. The tumor is commonly found in the spleen and liver, and it has been reported in the literature that it can be associated with paraneoplastic pemphigus, myasthenia gravis, and other diseases. A case of IPT-like FDCS with clinical features of thrombocytopenia has not been reported. PATIENT CONCERNS A 59-year-old male patient visited our hospital in September 2020 due to bleeding gums and epistaxis. DIAGNOSIS Splenic lymphoma with marked thrombocytopenia was initially diagnosed. The patient underwent pathological examination after splenectomy. Microscopic examination showed spindle-shaped or oval cells arranged in loose bundles, a large number of lymphocytes and plasma cells infiltrating the interstitium, and fibrin-like changes in the blood vessel wall. Immunohistochemical detection of tumor cells was positive for CD21, CD35, and Epstein-Barr virus in situ hybridization, and the patient was diagnosed with IPT-like FDCS. INTERVENTIONS The patient underwent a splenectomy. The patient received platelet-raising therapy postoperatively. OUTCOMES No tumor recurrence or metastasis was found during the 17-month follow-up period, and the platelet count returned to normal. CONCLUSION IPT-like FDCS is an uncommon tumor, and its first presentation with marked thrombocytopenia is even rarer. The tumor was clinically and radiographically nonspecific. Definitive diagnosis relies on histopathological and immunohistochemical staining. IPT-like FDCS is biologically indolent and has a favorable prognosis.

Abstract
A 45-year-old woman with abdominal pain after minor trauma was referred to our hospital. Computed tomography (CT) showed a hypovascular tumor in the left liver lobe. A tumor biopsy revealed granuloma, although no findings indicated malignancy or infection. A follow-up imaging study showed spread of the hepatic tumor. Her abdominal pain worsened after a second minor trauma. CT revealed an intratumor abscess, and pus overflowed from the patient's umbilicus. The abscess was improved by antibiotics and drainage therapy. In this case, unusual imaging findings and an atypical disease course of a hepatic inflammatory pseudotumor were observed.

Abstract
BACKGROUND A retro-odontoid pseudotumour compressing the spinal cord and causing myelopathy is often associated with an inflammatory condition such as rheumatoid arthritis. A degenerative non-inflammatory retro-odontoid pseudotumour responsible for clinically relevant spinal cord compression is a rare condition described in small clinical series and is likely associated with craniovertebral junction hypermobility or instability-like conditions. For several years, direct removal of the lesion through an anterior or lateral approach has been advocated as the best surgical option. However, in the last decade the posterior approach to the craniovertebral junction, to perform C1-C2 fixation and C1 laminectomy without removal of the retro-odontoid tissue, has demonstrated its efficacy in reducing retro-odontoid pannus as well as in obtaining improvement of myelopathy. METHODS In this paper we analyse the clinical and radiological outcomes of seven patients (five males and two females) treated with posterior C1-C2 fixation and C1 laminectomy for a degenerative non-inflammatory retro-odontoid pseudotumour responsible for spinal cord compression. C1 laminectomy provided immediate spinal cord decompression. We also review the relevant literature focusing on associated cervical degenerative conditions that may contribute to triggering or acceleration of atlantoaxial hypermobility or 'instability', causing formation of the retro-odontoid tissue. RESULTS The mean follow-up period (of six followed-up patients) was 55.8 months (range 10-96 months). In all cases the Nurick score at the latest follow-up visit demonstrated clinical improvement; magnetic resonance imaging during follow-up demonstrated progressive reduction of the retro-odontoid pseudotumour in all but one patient, who died of surgery-unrelated disease in the early postoperative period. No vascular or neural damage secondary to C1-C2 fixation was observed. CONCLUSION C1-C2 fixation associated with C1 laminectomy is an effective surgical option to treat myelopathy secondary to a degenerative retro-odontoid pseudotumour. In these cases, direct removal of intracanalar tissue compressing the spinal cord is not required, as C1-C2 fixation is sufficient to cause its disappearance.

Abstract
A 42-year-old woman with complaints of fever and abdominal pain, was diagnosed to have perforative appendicitis, for which emergency surgery was performed. Marked thickening and edema around the cecum, ileum, and the mesentery was observed. Ileocecal resection was performed, as malignant disease could not be excluded. Histopathological examination revealed abscess formation in the lining membrane of the intestine, inflammatory granulation and proliferation of the spindleshaped cells in the serosal membrane extensively, and an inflammatory pseudotumor(IPT)was diagnosed. It is generally difficult to clearly distinguish IPT from a malignant tumor before surgery. We thus report this case, along with a review of literature.

Abstract
Inflammatory pseudotumor (IP) is an uncommon idiopathic lesion that often imitates malignancy clinically and radiologically. Inflammatory pseudotumors have been found to occur in various sites but rarely in the head and neck. The histopathology, imaging, and treatment of three unique cases of head and neck inflammatory pseudotumors are described in this case series. Patients in Cases 1 and 2 presented with right level II neck mass and left parotid tail mass, respectively. The patient in Case 3 presented with otalgia, jaw pain and trismus, and a left parapharyngeal space mass. The tumors in Cases 1 and 3 significantly decreased in size with tapered courses of oral corticosteroids. The tumor in Case 2 was surgically excised without disease recurrence. Malignancy must be ruled out with incisional or excisional biopsy. Treatment includes surgical excision, oral corticosteroids, or both. The literature shows that radiotherapy and small-molecule inhibitors may be promising alternatives.

Abstract
BACKGROUND AND PURPOSE There are no international guidelines to define adverse reaction to metal debris (ARMD). Muscle fatty atrophy has been reported to be common in patients with failing metal-on-metal (MoM) hip replacements. We assessed whether gluteal muscle fatty atrophy is associated with elevated blood metal ion levels and pseudotumors. PATIENTS AND METHODS 263 consecutive patients with unilateral ASR XL total hip replacement using a posterior approach and with an unoperated contralateral hip were included in the study. All patients had undergone a standard screening program at our institution, including MRI and blood metal ion measurement. Muscle fatty atrophy was graded as being absent, mild, moderate, or severe in each of the gluteal muscles. RESULTS The prevalence of moderate-to-severe gluteal muscle atrophy was low (12% for gluteus minimus, 10% for gluteus medius, and 2% for gluteus maximus). Muscle atrophy was neither associated with elevated blood metal ion levels (> 5 ppb) nor with the presence of a clear (solid- or mixed-type) pseudotumor seen in MRI. A combination of moderate-to-severe atrophy in MRI, elevated blood metal ion levels, and MRI-confirmed mixed or solid pseudotumor was rare. Multivariable regression revealed that "preoperative diagnosis other than osteoarthrosis" was the strongest predictor of the presence of fatty atrophy. INTERPRETATION Gluteal muscle atrophy may be a clinically significant finding with influence on hip muscle strength in patients with MoM hip replacement. However, our results suggest that gluteal muscle atrophy seen in MRI is not associated with either the presence or severity of ARMD, at least not in patients who have been operated on using the posterior approach.

Abstract
INTRODUCTION Inflammatory myofibroblastic tumors (IMT) are rare neoplasms characterized by a proliferation of spindle-shaped cells with a stroma infiltrated by macrophages, lymphocytes and plasma cells. CASE REPORT We report a case of 59 years old male who presented an acute abdomen due to a mass of the mesentery of the terminal ileum, which was perforated with active bleeding. Histopathology reported a low-grade TMI with clear margins. DISCUSSION Inflammatory myofibroblastic tumors of the mesentery are rare entities whose etio-pathogenia remains unclear. It requires a histopathological diagnosis and inmunohistochemical evaluation and its treatment is based on complete resection of the tumor. These type of neoplasms require close monitoring due to local recurrence.

Abstract
A 58-year-old woman with a 1-month history of right hand clumsiness and speaking difficulty was admitted to our hospital. A neurological examination revealed sensory aphasia and right hemiparesis. Her laboratory tests showed elevated serum levels of IgG and IgG4, pancytopenia, and liver dysfunction. The results of the imaging studies of her abdomen were compatible with sclerosing cholangitis. Brain MRI showed extensive signal abnormalities in the left hemisphere on T2-weighted and fluid-attenuated inversion recovery (FLAIR) images, extending from left internal capsule to the cerebral peduncle with an irregularly enhancing lesion in the left parietal lobe. A brain biopsy revealed lymphocyte and plasma cell infiltration and reactive gliosis. Most of the plasma cells were IgG positive; however, IgG4-positive plasma cells were sparsely observed. After the initiation of betamethasone treatment, her symptoms and the brain MRI abnormalities showed significant improvement. The brain biopsy results did not meet the current criteria of IgG4-related disease. This is the first reported case of a tumefactive lesion of the brain parenchyma with serum IgG4 elevation, which was responsive to steroid treatment. The accumulation of a greater number of reports on the pathological investigation of cases of possible IgG4-related disease may help to elucidate the exact role of IgG4 in IgG4-related disorders.

Abstract
INTRODUCTION Inflammatory myofibroblastic tumor (IMT), also known as inflammatory pseudotumor, plasma cell granuloma or inflammatory myofibroblastoma, is characterized histopathologically by myofibroblastic spindle cells with inflammatory cell infiltrates ( plasma cell, lymphocytes and eosinophils). Inflammatory myofibroblastic tumor is tipically seen in children or young adults and is most commonly localized in the lung, but it can occur anywhere in the body. CASE REPORT We present a case in a young woman with severe acute G.I. bleeding, an uncommon presentation of IMT in adults. The patient was admitted to the emergency department for melena. MRI showed a distal jejunum hypervascular mass. Other exams were negative. Surgical excision was recommended, so the patient underwent surgery with complete removal of the tumoral mass. No adjuvant therapy was employed and the patient is asymptomatic after 6 months of follow-up. DISCUSSION IMT is an rare lesion that mimics malignancy and is accompanied by various clinical manifestations. The treatment of choice is believed to be complete surgical excision and long term follow up. KEY WORDS Anemia, Inflammatory myofibroblastic tumor (IMT), Small intestine, Surgery.

Abstract
Inflammatory pseudotumor (IPT) is a rare space-occupying lesion of unknown etiology that can mimic malignancy on clinic-radiological and pathological examination. We describe a rare case of ileocecal intussusception from clinically suspected malignancy of the right colon where the patient underwent right hemicolectomy. Histopathology of the resected specimen confirmed IPT of the colon. This patient was observed to have abnormally elevated total leukocyte count and platelets before and after surgery. In an adult with intussusception associated with an abdominal mass, the possibility of IPT of the colon should be considered. Considering the abnormally high total leukocyte and platelet counts and colonic IPT, it is necessary to prevent postoperative adverse effects due to these changes. Although IPT of the colon is usually a benign process, controversy regarding its management still exists. We consider hemicolectomy as a safe treatment approach for colonic IPT and review the existing literature.

Abstract
Inflammatory pseudotumours of the paranasal sinuses are rare entities and can be easily confused with aggressive malignant tumours. In this report we describe the characteristic behavior of inflammatory pseudotumours in the maxillary sinus. We present a case of a 47-year-old Caucasian woman, who presented in our ENT department because of progressive nasal obstruction, epistaxis, and epiphora. The clinical as well as the radiological findings suggested a maxillary sinus neoplasm, most probably of malignant nature. The histopathological examination showed an inflammatory pseudotumour of the maxillary sinus with polypoid structure and no signs of malignancy.

Abstract
Inflammatory pseudotumor (IPT)-like follicular dendritic cell (FDC) sarcoma is a recently described rare tumor and considered a unique entity, with different histologic appearances and behavior from those of the classical FDC sarcoma. This study analyzed the clinical and pathological findings of two such cases that the authors encountered and 36 previously reported cases identified in the literature. Assessment of all 38 cases showed a slight female predominance (2.2:1) with a median age of 56.5 years. Seventeen patients complained of abdominal discomfort or pain, while fifteen patients had no clinical symptom. Almost all cases occurred in liver (n=20) or spleen (n=17). Except in one case, all patients underwent surgical resection of the tumor alone. Histologic features showed a mixture of chronic inflammatory cells and variable amounts of spindle cells with vesicular nuclei and distinct nucleoli. The tumor cells expressed conventional FDC markers such as CD21 (75%), CD35 (92%), CD23 (62%), clusterin (75%), and CNA.42 (100%). EBV was detected in thirty-five cases (92.1%) by Epstein-Barr virus (EBV)-encoded RNA in situ hybridization, and EBV-latent membrane protein-1 was expressed in 90% of the cases. With a median follow-up of 21 months, 29 patients (85.3%) were alive and well, 4 (11.8%) were alive with disease, one patient (2.9%) died of disease. Only four patients with hepatic tumors underwent recurrence or metastasis after initial treatment. Epstein-Barr virus is thought to play a role in the development of the tumor; however, the pathogenesis of the disease and the origin of tumor cells remain unclear.

Abstract
PURPOSE Authors analyzed their experience with urinary bladder tumours. This article discusses clinical and histopathological diagnostics and treatment procedures, and follow up of patients with rare benign urinary bladder tumours. METHODS 406 patients with bladder tumours were treated in our department between January 2000 and December 2008. 322 patients had superficial tumours and 84 had primary invasive tumours. All patients who underwent transurethral resections of these tumours were operated under general or spinal anaesthesia. The resected specimens were histologically examined in the department of Pathology. RESULTS 399 of the 406 patients had urothelial bladder cancer, 7 patients had a histologically uncommon type of bladder tumour, one female was diagnosed with sarcomatoid bladder cancer, one patient had a histologically confirmed feochromocytoma of the urinary bladder. Two males had epidermoid carcinoma. One female had a histologically described uncommon benign pseudoneoplastic lesion, chararacteristic for endosalpingiosis. Another two patients were diagnosed with inflammatory myofibroblastic tumour of the urinary bladder. Both patients presented with gross macroscopic haematuria. Authors performed complete transurethral tumour resections, which required several sessions and the deliberation of a blocked ureter through nephrostomy in one case. CONCLUSION More than 98 % of all treated patients had urothelial bladder cancer in different stages and grades. Two patients had rare benign inflammatory proliferation of the bladder wall which formed large tumorous bleeding masses obstructing the ureter in one case. These types of bladder tumour could be treated conservatively with meticulous long term follow up similarly to patients with bladder cancer (Tab. 1, Fig. 4, Ref. 15). .

Abstract
Plasma cell granuloma of the larynx is a rare benign lesion of unknown etiology, with only 21 cases reported previously. We report an additional case of plasma cell granuloma in which a 26-year-old man experienced a 1.5 × 3.4-cm, completely obstructing subglottic lesion. Because of the patient's young age, history of hemoptysis, bleeding from his tracheostomy, and the rarity of plasma cell granulomas, the patient was assumed to have hemangioma until proven otherwise. He presented with a partially obstructing glottic lesion 4 months later. Both the subglottic and glottic lesions were excised endoscopically. Multiple modalities have been used to treat plasma cell granulomas, including radiation, endoscopic CO2 laser ablation, high-dose prednisone, and open excision. In our case, steroids were given in the interim between the 2 excisions. This is the first report of a patient with two laryngeal plasma cell granulomas and the 22nd reported case of laryngeal plasma cell granuloma.
