Soft tissue sarcomas are malignant extraskeletal tumors of mesenchymal origin and uncommon in children.1,2 Rhabdomyosarcoma is most common and constitutes about 10 to 15% of the malignant neoplasms affecting children. The tumor is located with a high incidence in the head and neck region followed by the extremities and perineal region. We recently encountered one such interesting case of intrao...

The authors present a case of embryonal rhabdomyosarcoma of the middle ear in an adult patient. Computerized tomography indicated a malignant tumor and the diagnosis was confirmed by pathological analysis.

We report a rare case of rhabdomyosarcoma spontaneously arising in an anterior mediastinal teratoma in a 47-year-old male. The patient was found to have an anterior mediastinal mass on a chest X-ray, which was taken two months before his presentation to Asan Medical Center. A subsequent computed tomography scan revealed an 8.9×7.1×8.0 cm heterogeneous mass in the anterior mediastinum. He underw...

We report a case of a 3-year-old North African child, initially assessed for nonspecific urinary symptoms such as haematuria and burning urination. The ultrasound evaluation showed a vegetating mass occupying the lumen with weak vascular signs at the Colour-Doppler evaluation. An explorative cystoscopy was performed and it revealed a nonbleeding lesion, white in colour, pedunculated, projecting...

We report an unusual case of 9.5-cm-sized embryonal rhabdomyosarcoma arose from a mediastinal mature teratoma in a 46-yr-old man. A man presented with chest trauma as a result of an accident at 10 September 2011. On chest X-ray, an anterior mediastinal mass was detected. To obtain further information, chest computed tomography (CT) with contrast enhancement was performed, revealing an anterior ...

Perianal region is an uncommon site for Rhabdomyosarcoma. Early diagnosis is essential in these cases, as 25% of patients present with metastasis at the time of diagnosis. FNAC is simple and useful procedure for making an early diagnosis and helping clinicians for prompt intervention. Previously, a single case had been reported of rhabdomyosarcoma occuring 2 years after a surgery for hamartoma ...

A 12 year old female, presented with rapidly progressive visual loss following left hemi facial pain for 15 days duration. Anterior segment and fundus examination was normal. She was diagnosed as retro bulbar neuritis and received steroid therapy. CT scan of PNS revealed a mass limited to the nasopharyngeal area and an endoscopic biopsy of mass revealed to be rhabdomyosarcoma, embryonal type. S...

The common marmoset (Callithrix jacchus) is now widely used in various research fields, including toxicology. However, information about the background pathology of this species is scarce. Here, we report a case of rhabdomyosarcoma that spontaneously occurred in a common marmoset. A 44-month-old male common marmoset was euthanized due to bilateral hind limb paralysis. At necropsy, a 2×2×5-cm in...

INTRODUCTION The pituitary gland is an uncommon site for metastases, in particular from rhabdomyosarcoma. Some authors have reported a recent increase in the incidence of metastases at infrequent sites, such as brain or bone, probably due to the expanded treatment options and the resulting improved survival. Treatment options are limited, but must be discussed and adapted to the patient profile...

Jaundice in children is more often due to hepatic disease than obstruction. Differential considerations for obstructive jaundice in children include choledocholithiasis, choledochal cysts and rare neoplasms. Rhabdomyosarcoma, the most common soft tissue sarcoma in pediatric patients, typically involves the head and neck, genitourinary system and extremities. Embryonal rhabdomyosarcoma of the bi...
