Rhabdomyosarcoma is a common extramammary malignancy in pediatric age groups, but it rarely metastasizes to the breast. Breast rhabdomyosarcomas are commonly metastatic, with possible primary locations at the head and neck, trunk, extremities, retroperitoneum and perianal region. We report a case of primary alveolar rhabdomyosarcoma of the upper extremities in a 17-year-old adolescent female who presented with bilateral lower limb weakness and bilateral breast lumps.

Article Synopsis
  • Rhabdomyosarcoma (RMS) is a rare and aggressive pediatric cancer that commonly affects children and adolescents, with alveolar rhabdomyosarcoma (ARMS) often developing in areas like the trunk and head/neck.
  • An 11-year-old girl diagnosed with ARMS presented with a perianal mass, showing aggressive metastasis to the pleura, lymph nodes, and even bones, which is less common.
  • The case underscores the difficulties in diagnosing and treating ARMS, stressing the importance of early detection, advanced imaging techniques, and the need for ongoing research to develop better treatment options.

Background: Both rhabdomyosarcoma (RMS) and central retinal artery occlusion (CRAO) are rare medical diseases, and their simultaneous occurrence in the same patient is extraordinarily uncommon. This study presents a comprehensive overview of the clinical manifestations, diagnostic imaging results, and therapeutic interventions of a patient with both conditions.

Case Summary: In this report, we present a 30-year-old male who presented with significant protrusion, pain and vision loss and was diagnosed with RMS in the orbit and sinus with CRAO.

Rhabdomyosarcoma (RMS) is the most common soft tissue malignancy in childhood, accounting for 3% of all pediatric malignancies and 50% of all pediatric soft tissue sarcomas. In adolescents and young adults (AYA) however, RMS comprises only 6.5% of all soft tissue sarcomas.

Background: Rhabdomyosarcoma and other soft tissue sarcomas (STS) with high-risk features are still associated with an unsatisfactory outcome. We evaluated the efficacy of oral maintenance therapy added at the end of standard therapy in patients with high-risk rhabdomyosarcoma and STS.

Methods: CWS-2007-HR was a multicentre, open-label, randomised controlled, phase 3 trial done at 87 centers in 5 countries.

Unlabelled: Rhabdomyosarcomas (RMS) are one of the most common types of sarcomas in children and adolescents. The alveolar RMS subgroup is of particular interest because in some cases, the translocation of the and genes is combined with an amplification of the corresponding hybrid gene. According to literature data, the frequency of the translocation is 70-90% and the translocation 10-30%.
