PNET of the hallux.

We present the case of a 21-year-old lady who presented with a peripheral primitive neuroectodermal tumour (pPNET) of the distal phalanx of the right great toe. She had an amputation through her metatarso-phalangeal joint, the diagnosis having been confirmed histologically. Although her resection margins were clear and radiological staging revealed no metastases, she was commenced on adjuvant chemotherapy due to the high rate of metastases associated with the disease. Her surgery came after two years of intermittent pain and swelling of her toe, during which time she was undergoing conservative management, with serial visits to the outpatients department, of a radiological (magnetic resonance imaging) diagnosis of a haemangioma. This case report details her background, diagnosis and treatment as well as presenting a literature review of what is an unusual tumour in a previously unreported site.
