OBJECT: Pineal region tumors represent a rare and histologically diverse group of lesions. Few studies are available to guide management and the outcomes following stereotactic radiosurgery (SRS) are unknown for many histologies. METHODS: Patients who underwent SRS for a pineal region tumor and for whom at least 6 months of imaging follow-up was available were retrospectively assessed in five centers. Data was collected from the medical record and histology-level analyses were performed, including actuarial tumor control and survival analyses...

Papillary tumor of the pineal region (PTPR) is a neuroepithelial neoplasm first described in 2003. Despite the anatomic association of PTPR with the pineal gland, the features of these tumors resemble those of the ependymal circumventricular subcommissural organ (SCO) of the posterior third ventricle. Given the presumed distinct derivation of PTPR and pineal parenchymal tumors, we hypothesized that expression of lineage-specific transcription factors could distinguish these tumors and provide additional insight into the differentiation of PTPR...

Retinoblastoma (RB) is the most common intraocular malignancy in childhood. Approximately 40% of retinoblastomas are hereditary and due to germline mutations in the RB1 gene. Children with hereditary RB are also at risk for developing a midline intracranial tumor, most commonly pineoblastoma. We recommend intensive ocular screening for patients with germline RB1 mutations for retinoblastoma as well as neuroimaging for pineoblastoma surveillance. There is an approximately 20% risk of developing second primary cancers among individuals with hereditary RB, higher among those who received radiotherapy for their primary RB tumors...

BACKGROUND/AIMS: Survivors of retinoblastoma carry a lifetime risk of secondary malignancies. It is well established that external beam radiation increases this risk; however, the risk with ophthalmic artery chemosurgery (OAC) remains unknown. We report on 10 years of experience with OAC and the rate of second primary malignancy (SPM) development. METHODS: This is a single-centre retrospective review approved by the Memorial Sloan Kettering Cancer Center Institutional Review Board of all patients who received OAC over a 10-year period, from May 2006 to November 2016...

Pineal anlage tumor (PAT) is a rare subtype of pineoblastoma (PB), which shows a poor prognosis. We report a case of a 5-year-old boy with PB with a rhabdomyoblastic component. He presented at a local clinic with vomiting and was transferred to our hospital following discovery of a pineal mass. An endoscopic biopsy was performed and was diagnosed as a PB with a rhabdomyoblastic component. Histopathology of PAT is characterized by both neuroectodermal and ectomesenchymal differentiation, and only a few confirmed cases have been reported...

Patients with familial/heritable retinoblastoma (RB) are at increased risk of developing second malignancies throughout life, including a pineoblastoma (trilateral RB [TRB]) in early childhood. Current guidelines recommend regular surveillance brain imaging for those with heritable RB until 5 years of age. The presence of pineal cysts has been reported in patients with RB. Pineal cysts are thought to arise due to focal degeneration of the pineal gland and can be found incidentally. The finding of pineal abnormalities including cysts in children with RB on imaging is disconcerting, as it raises the possibility of an underlying malignancy, specifically a pinealoblastoma...

The existence of tumorspheres (TSs) might confer treatment resistance to pineoblastoma (PB). The existence of PB TSs with cellular immortalization potential has not yet been reported. We developed a procedure for isolating TSs from recurrent PB (rPB) and tested whether their properties made them suitable for use as a patient-derived xenograft (PDX). Immunocytochemical staining, RT-PCR and quantitative real-time PCR showed that, among stemness proteins, CD133, musashi and podoplanin were expressed at elevated levels in rPB TSs, but nestin was not...

INTRODUCTION: In benign pineal parenchymal tumors (PPTs), namely, pineocytoma(PC)and PPT of intermediate differentiation (PPTID), cytologic pleomorphism has occasionally been found;however, it is controversial as to whether the presence of pleomorphic cells leads to upgrading of tumors. We experienced a rare case of pleomorphic PPT in an elderly woman and compared it with a retrospective series of 12 PPTs (PC:3, PPTID:6, pineoblastoma[PB]:3)to evaluate the correlation between pleomorphism and the malignancy grade...
