Malignant sacrococcygeal germ cell tumour in an adult

In adults, malignant sacrococcygeal germ cell tumour is a rare cause for a presacral tumour, with only 17 cases having been reported in the literature since 1907. We report the case of a 34 year old male who presented with a 6 month history of symptoms relating to a malignant presacral tumour which required en bloc excision including the lower sacrum and rectum. He died with lung and mediastinal metastasis 7 months following surgical excision and adjuvant chemotherapy using Cisplatin, Bleomycin and Etoposide. Prior to his death, he had a severe polyarthritis of his peripheral joints and evidence of hypertrophic osteo-arthropathy. The literature indicates that adults with these tumours have a poor prognosis, with only one reported long-term survivor. Surgical excision offers the only chance of cure, with the role of adjuvant therapy not having been defined because of the small numbers.
