Introduction: Rhabdomyosarcoma is a high-grade malignant neoplasm with skeletal muscle differentiation; common soft tissue sarcoma in children but considered one of the rarest adults. Case description: We report case 35-year-old male chronic productive cough and haemoptysis for five days. A CT scan nasopharynx revealed blocked left maxillary ethmoid sinus bone destruction. These findings raised...

Cervical spinal Ewing's sarcomas are rare and cause problems in diagnosis. We present an unusual case of a primary extraosseous Ewing's sarcoma arising from the spinal cord. An 18-year-old woman with fever, headache and back pain lasting one month was admitted to the hospital. Whole body bone scintigraphy was performed with 1110 MBq technetium-99m methylenediphosphonate. Scintigraphy clearly sh...

BACKGROUND This study used receiver operating characteristic curve to analyze Surveillance, Epidemiology and End RESULTS (SEER) Ewing sarcoma (ES) outcome data. The aim of this study was to identify and optimize ES-specific survival prediction models and sources of survival disparities. MATERIALS AND METHODS This study analyzed socio-economic, staging and treatment factors available in the SE...

Primary extraosseous Ewing sarcoma is a rare entity, especially in the spinal epidural site. Less than 20 cases have been reported in the literature. Here, we present a previously healthy 12-year-old boy who complained of low back pain, progressive gait disturbance and weakness of right lower extremity for nearly one month before admission. Magnetic resonance imaging showed one solitary posteri...

Ewing sarcoma (ES)/ primitive neuroectodermal tumour (PNET) is an aggressive malignant neoplasm affecting mainly children and young adults. The tumour is included with other primitive neoplasms under the category of small round cell tumour. Cytokeratin expression in ES/PNET has been described in sporadic case reports as well as a few systemic series. We studied this feature in Malaysian patient...

A 50 year old white man received an incidental ultrasound diagnosis of hypoechoic mass interesting the right seminal vesicle. A CT scan showed the presence of a 7.8 cm roundish cyst, originating from the right seminal vesicle. He had been followed by the removal of the right seminal vesicle and both the cystic lesion. The histological findings of the specimen documented the presence of small ro...

Extraskeletal myxoid chondrosarcoma (EMC) is a rare mesenchymal soft tissue tumour that poses diagnostic difficulty as it lacks a characteristic immunophenotype, in addition to its wide morphological spectrum. Microscopically, EMC shows strands and cords of relatively small cells with acidophilic cytoplasm that are occasionally vacuolated. Small cells with scant cytoplasm may comprise some EMC....

ary primary malignancy, particularly another primary soft tissue sarcoma. The incidence of a secondary primary STS occurring in a previously diagnosed adult STS patient is 12.5-fold risk of a normal health individual. Most reported synchronous or metachronous STS affect the head and neck or abdominal region, whereas those affecting the extremities are much rarer. The probability of primary STS ...

BACKGROUND Extraskeletal Ewing sarcoma (EES)/primitive neuroectodermal tumours (PNET) are rare soft tissue sarcomas. Prognostic factors and optimal therapy are still unconfirmed. MATERIALS AND METHODS We performed a retrospective analysis on patients to explore the clinic characteristics and prognostic factors of this rare disease. A total of 37 patients older than 15 years referred to our in...

Extraosseous Ewing's sarcoma/primitive neuroectodermal tumor (ES/PNET) is an uncommon, aggressive, and malignant tumor with a poor patient outcome. Its occurrence in the lesser sac is a rare event and to the best of our knowledge, has not been previously described. The present case was clinically and radiologically misdiagnosed as a pancreatic tumor/gastrointestinal stromal tumor. Histopatholog...
