BACKGROUND AND PURPOSE The Danish Cancer Patient Pathway for sarcoma defines a set of alarm symptoms as criteria for referral to a sarcoma center. This may exclude cancer patients without alarm symptoms, so we investigated the presence of alarm symptoms (defined as being indicative of a sarcoma) in patients who had been referred to the Aarhus Sarcoma Center. PATIENTS AND METHODS We reviewed t...

INTRODUCTION Synovial sarcomas are rare malignant tumors of soft tissues, arising mainly from periarticular structures. Gastrointestinal localizations are unusual presentation of these rare sarcomas. METHODS We present the case of a 56- years old man with monophasic synovial sarcoma, arising primarily from the ileum, and causing intussusception. A review of the literature was conducted to gat...

Pulmonary histiocytic sarcoma is a rare, but highly malignant disease. Its low incidence imposes significant difficulties on physicians confronted with affected patients. The reported patient is a 24-year old male with histiocytic sarcoma of the lung. Left lower lobectomy was performed. Histologically, tumor cells had no features of carcinoma. Several entities were raised as differentials: larg...

Ewing sarcoma arises in both bones (most common) and soft tissues it commonly affects young adults. The tumor is composed of small round cells showing positivity for CD99 FLI1 on immunohistochemistry (IHC). We describe ganglion cell differentiation post-chemotherapy which a rare phenomenon. A 13-year-old girl presented with chest wall mass. On biopsy correlating IHC, the diagnosis was rendered ...

p 53 T um o r S up p re ss o r Trp53 mouse germline knockout. Trp53−/− homozygous: 100% tumor penetrance at ?4.5 months. Typical tumors: T cell lymphoma (>60%); soft tissue sarcoma (?25%); osteosarcoma, brain tumors, teratoma (together <15%); carcinomas rarely observed. Trp53+/− heterozygous: 50% tumor penetrance at 17 months. Typical tumors: T cell lymphoma (?30%); soft tissue sarcoma (?30%); ...

The possibility of having experimental models of brain tumors allows for testing therapies applicable to human brain tumors. They can be induced by viruses, chemicals or radiation. Radiation-induced brain tumors have seldom been used, but diverse virus groups have been used to induce brain tumors. Among DNA viruses, both adenoviruses and papovaviruses have been shown to induce brain tumors in a...

Although synovial cell sarcoma is reported to be the most common neoplasm of the canine synovium, this retrospective study of 35 canine synovial tumors found that the majority were of histiocytic origin. Five (14.3%) synovial cell sarcomas were identified by positive immunohistochemical staining with antibodies to cytokeratin. Eighteen (51.4%) histiocytic sarcomas were identified by cell morpho...

IntroductionNTRK fusion genes have been found in several solid tumors, among which NSCLC and sarcoma. Novel NTRK translocation-related tumors are still being discovered.MethodsWe report a 49-year-old patient with mass the left lower lung lobe that was resected. This specimen analyzed sequenced using targeted DNA next generation sequencing (NGS) anchored-multiplex-PCR (AMP) RNA NGS.ResultsOn pat...

Central nervous system metastases as the presentation of primary cardiac sarcoma are a very rare entity, with only a few previously reported cases. Sarcomas specifically make up 10 to 20% of all primary cardiac tumors. Patients with primary cardiac tumors typically present with cardiac symptomatology that may include arrhythmias, obstruction to blood flow and valve function, or symptoms of hear...
