The schwannoma-like pleomorphic adenoma is a rare histopathological variant of the pleomorphic adenoma. Five previous reports with seven cases exist in English language literature. These tumors present in the parotid gland most commonly. Intraparotid schwannomas of the facial nerve and schwannomas with glandular differentiation have also been reported. A 60-year-old male presented with an asymptomatic swelling over the left angle of the mandible. The swelling had been present for about 12 years with a recent increase in size...

BACKGROUND: Euro-EWING 99 trial of the European Ewing tumor Working Initiative of National Groups (EE99) was an international phase III study in patients with Ewing sarcoma. The German Society of Pediatric Oncology and Hematology (GPOH) data center registered and followed patients with other diagnoses than Ewing sarcoma who were treated according to the EE99 protocol in an additional non-Ewing database. PROCEDURE: Data of 27 patients with other diagnoses than Ewing sarcoma treated according to the EE99 protocol were analyzed...

Extraskeletal osteosarcoma is a rare and invasive malignancy, typically located in the soft tissue without attachment to the skeleton. The present study reports a case of a primary mesenteric extraskeletal osteosarcoma of a 71-year-old woman. The patient complained of an incomplete defecation. Colonoscopy showed an ulcer with impression of external compression of the sigmoid. An additional abdominal computed tomography (CT) scan revealed a large, almost completely calcified, mass in the left lower abdomen causing hydronephrosis of the left kidney...

Introduction Malignant rhabdoid tumor (MRT) is defined as a high-grade sarcoma derived from an uncertain cell of origin. Its diagnosis is associated with poor prognosis and patient's life expectancy is greatly reduced. Material and method Here, we describe a unique case of 9-month-old boy who presented with a large MRT arising from the soft tissue of the neck. Following intensive multimodal treatment, the patient benefited from a 25 years' remission until the discovery of multiple liver metastases. Conclusion MRT of soft tissue needs to be distinguished from other soft tissue neoplasms, as MRT is highly aggressive and is usually associated with a poor outcome...

Primary Ewing sarcoma / primitive neuroectodermal tumor (ES) of the kidney is a rare neoplasm with limited clinicopathologic data. We report 23 such cases with no history of ES elsewhere in the body. The patients included 13 male and 10 female, aged 8-70 years (mean, 31 years). The average tumor size was 11.7 cm (range, 5-20 cm). Microscopic analysis showed predominantly lobular growth (n = 14), with focal papillary (n = 3), alveolar (n = 1), and hemangiopericytoma-like (n = 1) patterns. Several tumors (n = 11) exhibited robust mitotic activity (>10 mitoses/10 high-power fields)...

Recent methodology has enabled the identification of some new genetic subgroups within the melting pot of lesions presently classified by the 2013 WHO classification as "undifferentiated/unclassified sarcomas". One of these subgroups is characterized by a paracentric inversion of the X chromosome with consequent formation of a BCOR-CCNB3 fusion. Clinical and pathological features of these tumors overlap with the Ewing sarcoma family as well as other soft tissue sarcomas, thus making them difficult to diagnose...

BACKGROUND: Extra-gastrointestinal stromal tumor is defined as a mesenchymal neoplasm arising from soft tissues outside the gastrointestinal tract. Prostatic extra-gastrointestinal stromal tumor has rarely been noted. CASE REPORT: A 56 year-old man presented with pain in the anal region. A digital rectal examination revealed that the prostate was markedly enlarged with a smooth, bulging surface. Computerized tomography images showed a 6 cm heterogeneous, infiltrative tumor within the prostate gland extending to the trigon of the bladder, left seminal vesicle and rectum...

BACKGROUND: Mediastinal thymic seminomas are rare male germ cell tumors with extragonadal origin that appear predominately with a cystic appearance. CASE PRESENTATION: A 22-year-old male was referred to our department for further investigation of a mediastinal mass discovered incidentally during routine chest X-ray. The patient has denied any symptoms including dyspnea, chest pain, cough, fever, dysphagia, hemoptysis, weight loss, and weakness. His past medical history was remarkable for orchitis, for which he had undergone a bilateral testicular biopsy, without the latter however, indicating the presence of a germ cell tumor or a premalignant lesion...

REVIEW
Frank Peinemann, Heike Enk, Lesley A Smith
BACKGROUND: Soft tissue sarcomas (STS) are a highly heterogeneous group of rare malignant solid tumors. Nonrhabdomyosarcoma soft tissue sarcomas (NRSTS) comprise all STS except rhabdomyosarcoma. In people with advanced local or metastatic disease, autologous hematopoietic stem cell transplantation (HSCT) applied after high-dose chemotherapy (HDCT) is a planned rescue therapy for HDCT-related severe hematologic toxicity. The rationale for this update is to determine whether any randomized controlled trials (RCTs) have been conducted and to clarify whether HDCT followed by autologous HSCT has a survival advantage...

Myeloid sarcoma is an extramedullary collection of blasts of the myeloid series that partially or totally effaces the architecture of the tissue in which it is found. These tumors have been described in many sites of the body, but the skin, lymph nodes, gastrointestinal tract, bone, soft tissue, and testes are most common. They can arise in a patient following the diagnosis of acute myeloid leukemia, but they may also be precursors of leukemia and should be considered diagnostic for acute myeloid leukemia. The differential diagnosis of this neoplasm includes malignant lymphoma, with which it is often mistaken, leading to diagnostic and therapeutic delays...

CIC-DUX4 sarcoma (CDS) or CIC-rearranged sarcoma is a  subcategory of small round cell sarcoma resembling the morphological phenotypes of Ewing sarcoma (ES). Hoever, recent clinicopathologic and molecular genetic analyses indicate that CDS is an independent disease entity from ES. Few ancillary markers have been used in the differential diagnosis of CDS, and additional CDS-specific biomarkers are needed for more definitive classification. Here we report the generation of an ex vivo mouse model for CDS by transducing embryonic mesenchymal cells (eMC) with human CIC-DUX4 cDNA...

RATIONALE: Primary bone lymphoma (PBL) is a rare malignant entity. There is a better survival of PBL than any other malignant bone tumors and extranodal lymphomas. PATIENT CONCERNS: We report a rare case of PBL involving radius and tibia. The patient was a 14-year-old girl with left forearm pain and swelling after trauma. Six months later after the last chemotherapy and radiotherapy, pain and swelling of left knee was presented. DIAGNOSES: Radiological imaging revealed a lytic destruction, periosteal reaction, and pathological fracture of radius and tibia with soft tissue mass...

BACKGROUND: Metastatic carcinoma to the jaws and oral region are very rare, representing less than 1% of all oral tumors. Unfortunately, oral metastasis is usually manifestation of an advanced stage of primary cancer, and indicates widespread disease and poor prognosis. MATERIAL AND METHODS: In this retrospective study, a total of 2039 patients with history of oral malignant tumor between 1980 and 2012 at Seoul National University Dental Hospital were evaluated...

Pseudoaneurysms are rare and are most commonly caused by blunt trauma. Taking a clinical history and doing an examination are very helpful to clinicians in making a diagnosis. Also, imaging methods are very useful in distinguishing a pseudoaneurysm from soft-tissue tumors. Early diagnosis and treatment are crucial in preventing the development of possible complications. The treatment approach varies according to the localization and the size of the lesion, and the presence of complications. We present a case - with imaging and surgical findings - of a pseudoaneurysm in a 27-year-old male in the second web interval after a penetrating trauma...

Neurofibroma (NF) is a benign tumor of the peripheral nervous system. Head and neck NF are generally located in the soft tissue. The tumour is rarely seen intraosseously and most commonly such tumours are seen as solitary lesions, rather than part of neurofibromatosis. The following report describes a case of an intraosseous neurofibroma in a 45-year-old male located in the left posterior mandible. The diagnosis was made based on the clinical findings, radio graphical features, histopathology, and immunohistochemistry...
