Recurrence of primitive germ cell tumour 20 years on.

We present a case of a woman in her 20s, with a prior history of paediatric sacrococcygeal germ cell tumour, presenting with a 6-month history of perianal pain. An MRI pelvis revealed a heterogeneous soft tissue mass causing destruction of the sacrococcygeal bone. A staging CT demonstrated metastatic deposits in the lungs and hypodense foci in the liver suspicious of metastatic disease. Her alpha-fetoprotein levels were raised and a CT-guided biopsy was in keeping with recurrent germ cell tumour. She was referred to a national centre for the treatment of germ cell tumours in adults and was rechallenged with cisplatin-based multiagent chemotherapy with a curative intent. This case raises the important question of how long we should follow-up these patients and whether they can ever be safely discharged from oncology surveillance.
