Primary cardiac rhabdomyosarcoma in a mitral valve involved with rheumatic disease

A 51-year-old female underwent emergency mitral valve replacement for mitral stenosis with an undetermined mass which was attached to the anterior mitral leaflet. Histopathological testing of the excised specimen confirmed the diagnosis of rheumatic mitral disease in combination with a primary rhabdomyosarcoma. Postoperative adjuvant chemotherapy with pazopanib hydrochloride was given. At 10 months of follow-up, repeated computed tomographic screening has not shown any signs of local recurrence or secondary metastases. The potential for the existence of primary rhabdomyosarcomas should be borne in mind when faced with undetermined masses on mitral leaflets, even in the presence of rheumatic disease.

Successful management strategy for giant primary hepatic rhabdomyosarcoma in 15-year-old male: a case report

Primary hepatic rhabdomyosarcoma is an exceedingly rare type of sarcomas. A 15-year-old boy was admitted to the hospital with abdominal pain. Serial investigation showed a giant heterogeneous mass, with a diameter of 15 cm, located in the right lobe of the liver (segment 4a, 4b, 5, 6, 7, 8), with clear margins, non-homogeneous density in computerized tomography and the Positron Emission Tomography Scan Multi Slice revealed a peripherally slightly metabolically active hepatic mass (205 × 134 × 208 mm). Histopathological examination and the Immunohistochemical showed embryonal rhabdomyosarcoma. The management strategy involved multiple cycles of ifosfamide and doxorubicin and monitoring the tumor size, until the tumor size was suitable for the surgery. The management of hepatic rhabdomyosarcoma is a surgical challenge due to the late onset of symptoms, a limited number of reported cases, and poor prognosis. Surgical excision is the treatment of choice for primary hepatic rhabdomyosarcoma and combination between chemotherapy, surgery showed good results.

Synovial sarcoma of the maxillary sinus - A rare condition managed with a rationalized surgery

Introduction

and importance: Synovial sarcoma is a type of spindle cell tumors with unknown cellular origin. It can present anywhere throughout the body; however, its onset in the maxillary sinus is an extremely rare condition, making it hard to diagnose. This tumor occurs equally, without predilection for males or females, and the incidence peaks in the age of 35. The diagnosis is confirmed by histopathological study, and the main treatment is complete surgical excision.

Case presentation

We are reporting a case of a 53-year-old male with a left sided hearing loss accompanied by a left sided nasal block and a vague facial and dental pain.

Clinical discussion

Magnetic Resonance Imaging (MRI) showed a heterogeneously enhancing tumor in the maxillary sinus that extended to the pterygopalatine fossa and other surrounding structures, and a biopsy showed the tumor to be a synovial sarcoma. The tumor was managed with a less aggressive curative surgery, and was put on an adjuvant radiotherapy, and is being followed regularly; with no recurrence 5 months after therapy.

Conclusion

In conclusion, we are writing this report to introduce a case of synovial sarcoma in a rare location that was managed by a “cosmetically oriented” curative surgery, satisfactory results and prognosis.

•

Synovial sarcoma is a rare type of spindle cell tumors.

•

Synovial sarcoma of the maxillary sinus is a quite rare condition.

•

The term “synovial sarcoma” is an old misnomer.

•

The cellular origin of Synovial sarcoma is still unknown.

•

The main treatment for synovial sarcoma is surgical excision.

Rhabdomyosarcoma of the uterus with multiple metastases in a post-menopausal woman

Rhabdomyosarcoma (RMS) is a malignant soft tissue tumor, usually presenting in the head and neck in children, with frequent metastases to the lungs. In this report, we present a rare case of a post-menopausal RMS patient who presented with walking difficulties after hysterectomy. A computerized tomography scan revealed metastases spreading to the mediastinum, retroperitoneum, lungs, liver and bones. On a protocol of Gemcitabine and Carboplatin, the patient showed stability in the dimensions of the masses with significant improvement in her quality of life.
