AIMS To describe the histological appearances of bone marrow infiltrated with rhabdomyosarcoma at presentation and to determine their value in establishing the diagnosis. METHODS Patients presenting over seven years in the northern health region of England with rhabdomyosarcoma were studied. Bone marrow aspirates and trephine biopsy specimens taken at presentation were examined. RESULTS Sev...

Rhabdomyosarcoma (RMS) is the most frequent soft tissue sarcoma in children. The aim of study was to retrospectively review the treatment results of childhood rhabdomyosarcoma and identify prognostic factors. 60 children with rhabdomyosarcoma treated between 1996 and 2002 in Shafa Hospital were reviewed. The data were analyzed for clinico-epidemiological factors. Age, gender, race, histology ty...

Costello syndrome is caused by heterozygous de novo missense mutations in the protooncogene HRAS with tumor predisposition, especially rhabdomyosarcoma. We here report two pediatric patients with Costello syndrome and umbilical ligament rhabdomyosarcoma. A review of the literature published in English in MEDLINE from January 1971 to June 2016 using the search terms "Costello syndrome" and "rhab...

The dose-limiting toxicity caused by standard chemotherapy has become a major roadblock to successful rhabdomyosarcoma chemotherapy. By screening a thiazolidinone library including 372 compounds, a novel synthetic compound, 2-((4-hydroxyphenyl)imino)-5-(3-methoxybenzylidene)thiazolidin-4-one (MHPT), was identified as a potent and selective anti-rhabdomyosarcoma agent. MHPT inhibited 50% of the ...

Rhabdomyosarcoma of the middle ear is a rare tumor, even rarer in adults and has a very poor prognosis. We report here an unusual case of rhabdomyosarcoma in middle ear of an adult, mimicking chronic suppurative otitis media and facial nerve palsy.

To address the poor outcomes in rhabdomyosarcoma, particularly the alveolar subtype, new therapies are needed. Potential cancer-specific alterations that may be molecular targets include gene fusions or copy number changes. Following the latter strategy, an attractive antigene approach was developed to inhibit MYCN oncogene expression in rhabdomyosarcoma.

Adult renal rhabdomyosarcoma is a rare subtype of renal sarcoma. We present a case of a renal mass treated with radical nephrectomy that subsequently was shown to be renal rhabdomyosarcoma. We discuss the clinical presentation, imaging findings, and histology for this case and review the available literature.

Rhabdomyosarcoma (RMS) is a malignant tumor of mesenchymal origin typically affects children and adolescents, with an annual incidence of 4.3 cases per 1 million population aged <20 years. Para testicular RMS is rare, constituting 4-7% of all RMS in children and young adults. Here we report a case of 16-year old boy with right paratesticular solid mass. Ultrasound revealed vascular paratesticul...

A patient with rhabdomyosarcoma is described in whom the presenting clinical and laboratory features were those of disseminated intravascular coagulation. The patient's rapid downhill course was primarily expressed by haemorrhagic tendency. An alveolar rhabdomyosarcoma, affecting many organs, including vascular and cardiac lumina, was found at necropsy and was considered to be the cause of the ...

A 7-month-old Holstein heifer presented with posterior paresis and megaesophagus. At post mortem examination, a nodular tumor was found attached to the thoracic wall and the eighth to eleventh thoracic vertebrae, adjacent to the left posterior pulmonary lobe. The tumor was diagnosed as rhabdomyosarcoma by histology. This is a very rare case of spinal infiltration of rhabdomyosarcoma in cattle.
