Tumor papilar de la región pineal: a propósito de un caso

Tumours of the pineal region are infrequent but papillary tumours in this location are even rarer. We present a case of a 30 year old woman with a 2 cm solid cystic tumour of the pineal region. Histologically it was a papillary lesion, positive for cytokeratin. Differential diagnoses of papillary ependymoma, papillary meningioma, papilloma/carcinoma of the choroid plexus and metastatic papillary carcinoma were considered, but the results indicated that the final diagnosis was papillary tumour of the pineal region. There are only 96 previous cases of this tumour in the literature to date.
