Paratesticular pleomorphic rhabdomyosarcoma in an adult

Area of Science:

• Pediatric Oncology
• Surgical Oncology
• Rare Cancers

Background:

• Rhabdomyosarcoma (RMS) is the most frequent soft tissue sarcoma in children and young adults, accounting for 6.5% of pediatric malignancies.
• Paratesticular RMS, while often having a good prognosis due to early diagnosis and resection, can present challenges with retroperitoneal lymph node invasion.
• Multidisciplinary treatment has improved outcomes, with a 2-year survival rate of 80% for paratesticular RMS.

Observation:

• This report details a rare case of paratesticular pleomorphic RMS, an unfavorable variant.
• The patient presented with paratesticular pleomorphic RMS, a subtype known for its poor prognosis.

Findings:

• The patient achieved a 60-month disease-free status following a multidisciplinary treatment approach.
• Successful management of a rare and prognostically unfavorable paratesticular pleomorphic RMS variant was achieved.

Implications:

• This case demonstrates the potential efficacy of a multidisciplinary strategy in managing rare and aggressive forms of pediatric RMS.
• Long-term disease control is achievable even with prognostically unfavorable variants of paratesticular RMS through comprehensive care.
• Highlights the importance of a multidisciplinary team in optimizing outcomes for rare pediatric cancers.
