Publication Open Access An Astonishing Extrarenal Wilms Localisation; Spinal Cord(2022-06-01) TOKUÇ, AYŞE GÜLNUR; BOZKURT, SÜHEYLA; KAÇAR, KADRİYE EBRU; EKER, NURŞAH; SAKAR, MUSTAFA; TOKUÇ A. G., EKER N., Tas B. T., BOZKURT S., SAKAR M., Aras S., AKAR K. E.Wilms\" tumour is a renal tumour mostly seen during the first 5 years of life and it accounts for 95% of renal malignancies during childhood. Its origin is primitive metanephric cells and, very rarely, it may occur in places other than the kidneys. The estimated rate of nephroblastoma outside the kidneys is approximately 0.5 to 1% of Wilms\" tumour cases. In this article, we report on a 3-year-old female patient who first presented with spinal dysraphism and a mass in the lumbar spinal cord with a histopathological diagnosis of nephrogenic rest, and after one year, a Wilms tumour arose in this location. This is a very rare extrarenal Wilms\" tumour location. Here, we report on a case with immature renal cells located in the lumber spinal cord associated with spinal dysraphism and the development of Wilms\" tumour there after one year.Publication Metadata only Atypical Teratoid Rhabdoid Tumor in a Newborn: Can IVF Be a Risk Factor?(TAYLOR & FRANCIS INC) DAĞÇINAR, ADNAN; Rzayev, Turkay; Gokce, Kubra; Gucyetmez, Safak; Bozkurt, Suheyla; Dagcinar, Adnan; Tokuc, Gulnur; Yaman, Akan; Bilgen, Hulya; Ozek, ErenBackground In recent years, with the widespread use of assisted reproductive technologies, questions have arisen regarding the possible relationship between these infertile parents with assisted conception procedures and childhood cancers. Case report: We present a 23-day-old newborn conceived by in vitro fertilization (IVF) with a 53 x 46 x 38 mm intracranial mass detected by magnetic resonance imaging on the 15th postnatal day. The mass, removed on 23rd postnatal day, was an Atypical Teratoid Rhabdoid Tumor (ATRT), WHO grade 4. Conclusions: As far as we know, this is the only neonatally detected ATRT. Further studies are needed to investigate whether there is a causal relationship between IVF and childhood cancers.Publication Metadata only Malignancy and lymphoid proliferation in primary immune deficiencies; hard to define, hard to treat(WILEY, 2020) KOÇ, AHMET; Kiykim, Ayca; Eker, Nursah; Surekli, Ozlem; Nain, Ercan; Kasap, Nurhan; Akturk, Hacer; Dogru, Omer; Canbolat, Aylin; Somer, Ayper; Koc, Ahmet; Tokuc, Gulnur; Bozkurt, Suheyla; Turkoz, Kemal; Karakoc-Aydiner, Elif; Ozen, Ahmet; Baris, SafaBackground Regarding the difficulties in recognition and management of the malignancies in primary immune deficiencies (PIDs), we aimed to present the types, risk factors, treatment options, and prognosis of the cancers in this specific group. Methods Seventeen patients with PID who developed malignancies or malignant-like diseases were evaluated for demographics, clinical features, treatment, toxicity, and prognosis. Results The median age of malignancy was 12.2 years (range, 2.2-26). Lymphoma was the most frequent malignancy (n = 7), followed by adenocarcinoma (n = 3), squamous cell carcinoma (n = 2), cholangiocarcinoma (n = 1), Wilms tumor (n = 1), and acute myeloid leukemia (n = 1). Nonneoplastic lymphoproliferation mimicking lymphoma was observed in five patients. The total overall survival (OS) was 62.5% +/- 12.1%. The OS for lymphoma was 62.2% +/- 17.1% and found to be inferior to non-PID patients with lymphoma (P = 0.001). Conclusion In patients with PIDs, malignancy may occur and negatively affect the OS. The diagnosis can be challenging in the presence of nonneoplastic lymphoproliferative disease or bone marrow abnormalities. Awareness of susceptibility to malignant transformation and early diagnosis with multidisciplinary approach can save the patients' lives.
