Paratesticular rhabdomyosarcoma: a case report.

Area of Science:

• Oncology
• Pathology

Background:

• Paratesticular rhabdomyosarcoma is an extremely rare malignancy.
• These tumors typically affect pediatric and adolescent populations.

Observation:

• A 16-year-old male presented with a rapidly growing paratesticular mass.
• Initial ultrasound revealed a heterogeneous paratesticular tumor with internal vascularity.

Findings:

• Pathological diagnosis confirmed rhabdomyosarcoma post-orchiectomy.
• Recurrence occurred 13 months later with retroperitoneal mass, ureterohydronephrosis, and lung metastases.
• The patient did not respond to salvage chemotherapy and rapidly declined.

Implications:

• Paratesticular sarcomas are aggressive and have a dismal prognosis.
• This case underscores the challenges in managing advanced paratesticular rhabdomyosarcoma.
