CASE REPORT A 25-year-old woman with right subacute sinusitis, complained about discomfort in her right eye. Clinical manifestations and computed tomography were suggestive of sub-periosteal orbital ethmoid wall abscess, for which the patient underwent urgent drainage. A solid tumor was found, with a positive biopsy for alveolar rhabdomyosarcoma. Complete remission and resolution of orbital sym...

Intracranial rhabdomyosarcoma is a very rare disorder. Subdural rhabdomyosarcoma has not been reported yet. It can be misdiagnosed with chronic subdural hematoma in CT images. Herein, we presented a 2.5-year-old boy with intractable chronic subdural hematoma who were treated with burr hole insertion, needle aspiration and shunting for about 2 years with partial resolution of his symptoms after ...

smNopsis A series of 34 cases of embryonal sarcoma and embryonal rhabdomyosarcoma of the orbit has been placed histologically into three groups according to their maximum degree of differentiation at any stage: (a) embryonal sarcoma, (b) non-striated embryonal rhabdomyosarcoma, and (c) striated embryonal rhabdomyosarcoma. The patients were then followed up. This paper presents a summary of the ...

Rhabdomyosarcoma is an aggressive soft tissue malignancy of childhood and adolescence arising from embryonal mesenchyme [1]. As compared to literature available, these tumours are mainly discussed in context of case studies. Most common affected sites are head, neck, abdomen and genitourinary tract [2]. Embryonal rhabdomyosarcoma is the most common subtype, of which botryoid is a polypoidal var...

A comparative study of beta enolase and myoglobin as markers of muscle differentiation in rhabdomyosarcoma was carried out, using an immunoperoxidase peroxidase antiperoxidase technique. Material from 26 cases of childhood rhabdomyosarcoma was studied and subdivided into embryonal and alveolar types. Positive cytoplasmic staining for beta enolase was seen in 85% of tumours studied (91% alveolar...

A 70-year-old man who visited Samsung Medical Center reported experiencing palpitation for 2 weeks. He had undergone excision of a mass in the right buttock due to rhabdomyosarcoma 7 years prior to this visit. Transesophageal echocardiography showed a pedunculated mass in the left ventricle, which was thought to be a vegetation of infective endocarditis, metastasis of the primary tumor, or thro...

Embryonal rhabdomyosarcoma of orbit presenting as a case of rapid proptosis of the right eye is reported in a 4 year old male child. There was no evidence of recurrence during a follow up of 6 months. Rhabdomyosarcoma is one of the most common primary malignant orbital neoplasms of child hood. It usually produces a precipitously progressing unilateral proptosis of sudden onset. It is a highly m...

WHAT IS RHABDOMYOSARCOMA? There are two kinds of muscle cells in the body: smooth muscle cells and skeletal muscle cells. Smooth muscles control involuntary activities; skeletal muscles control voluntary activities. Rhabdomyosarcoma (RMS) is a malignant tumor ("cancer") that arises from a normal skeletal muscle cell. Not very much is known about why normal skeletal muscle cells become cancerous...

Spindle cell/sclerosing rhabdomyosarcoma (ssRMS) is a new subtype of rhabdomyosarcoma included in the World Health Organization soft tissue and bone tumor classification in 2013. Despite the increasing number of reported cases of ssRMS, the imaging characteristics of ssRMS are not established. Herein, we present the case of an elderly Japanese woman with ssRMS of the masticator space with intra...
