“…Among these patients, 10 were children under 16 years of age (Table 1) [5][6][7]12,13]. Clinical manifestations include headache, diplopia, dizziness and vomiting [5,[12][13][14]. Spinal dissemination is rare at the time of diagnosis.…”

Pediatric papillary tumors of the pineal region: to observe or to treat following gross total resection?

We present the case of a 3-year-old girl diagnosed with PTPR. Due to her young age, adjuvant radiotherapy was omitted after gross total tumor resection. Thirty-six months later, local tumor recurrence occurred. Considering the possible risks of secondary surgery, the recurrent tumor was irradiated with proton radiotherapy. Three months later, the tumor showed near-complete remission. DISCUS-SION: Based on this experience and other pediatric case reports from the literature, local radiotherapy might be suggested also after complete tumor resection.

“…[ 28 ] The term “PTPR” is based on the histopathological description of a tumor characterized by a papillary pattern, rosettes, and pseudorosettes. [ 22 ] Microscopic evaluation often demonstrates a lesion with papillary areas lined by epithelioid tumors with eosinophilic cytoplasm, and numerous cells exhibiting clear or vacuolated cytoplasm. [ 36 ] Since first description of PTPR, growing awareness familiarized pathologists with the presentation of PTPR and increased recognition as well as revision demands.…”

Background: Papillary tumor of the pineal region (PTPR) represents a rare and histologically distinct subgroup of tumors originating in the pineal region. Few pediatric cases have been reported so far in the literature; therefore, clinical data are scarce. Case Description: We describe a case of PTPR in a 9-year-old girl who presented with a 5-month history of excessive appetite and weight gain. The patient underwent neuroimaging procedures and total gross surgical resection with postoperative adjuvant local radiotherapy, which from our experience was the best treatment choice as an attempt to avoid local recurrence. During 78-month follow-up, the patient from our study manifested no disease recurrence. Conclusion: PTPR should be included in the differential diagnosis of pineal region masses.

“…The term ‘PTPR’ is based on the histopathological description of a tumor characterized by a papillary pattern, rosettes and pseudorosettes ( 11 ). Other tumors of the pineal region manifested by papillary features include pineal parenchymal neoplasms, choroid plexus papilloma, papillary ependymoma, metastatic papillary carcinomas, papillary meningioma and germ cell tumors.…”

“…The tumor was removed via a suboccipital transtentorial approach ( 11 ). During surgery, the tumor appeared grayish, soft, well-circumscribed and markedly vascular, exhibiting adhesion to the deep venous system and strong adhesion to the corpora quadrigemina.…”

Papillary tumor of the pineal region (PTPR) was first described as a distinct tumor entity in 2003 and was introduced into the World Health Organization classification of central nervous system tumors in 2007. This tumor is rare and, to the best of our knowledge, only 7 cases have been reported in children <16 years of age, while the youngest documented patient was a 15-month-old boy. The present study reported a case of PTPR in a 10-year-old girl who underwent magnetic resonance imaging and surgical resection of tumors. Histological and immunohistochemical staining results were presented. Patients with PTPR require long-term follow-up, and the patient of the present study has continued to do well, with no recurrence of the tumor at the 15-month follow-up examination. In addition, a review of the literature on this unusual neoplasm was performed, along with discussion of their differential diagnosis.
