Subcutaneous myxopapillary ependymoma
Subcutaneous myxopapillary ependymoma is a very rare entity, and to our knowledge this is the first published case from Denmark. A previously healthy 32-year-old male presented with subcutaneous swelling and tenderness located at the top of the intergluteal cleft. The circular soft tumour, measuring 1.7 × 1.7 × 1.2 cm, was removed surgically. After histopathological examination with several immunohistochemical and special stainings, the diagnosis surprisingly was subcutaneous myxopapillary ependymoma. The tumour was removed with free margins and no metastases were found on follow-up CT- and MRI scans.
