El oligodendroglioma de la médula espinal es una neoplasia extremadamente rara y solo se han reportado 52 casos en la literatura. Se reporta el caso de un paciente varón de 52 años, con paraplejia y un tumor en la medula espinal a nivel de C7 a T4. El diagnóstico final fue oligodendroglioma anaplásico con deleción del cromosoma 1p.

Objectives. The latest WHO classification of hematopoietic and lymphoid neoplasms considers 29 mature T and NK cell lymphomas. One of these corresponds to peripheral T-cell lymphoma, without another specification (LCTP-NOS). The objective of this research was to evaluate the clinical-pathological characteristics of this disease and its association with EBV infection in relation to global survival (OS). Methods. 65 cases with a diagnosis of LCTP-NOS were studied at the National Institute of Neoplastic Diseases in a period of 6 years. Clinical-pathological characteristics were evaluated, and OS and other clinical parameters were compared between cases with infection and without EBV infection. Results. There were (45 %) positive cases for EBV. The average age was 50 years and (29 %) were women. The proportion of patients with and without B symptoms was similar. The stages were usually advan...

Se reporta el caso de un niño de 10 años que se presentó con dos semanas de enfermedad caracterizada por cefalea, vómitos, marcha tambaleante y somnolencia. El examen clínico reveló bradilalia, ataxia, hiperreflexia, nistagmo horizontal y vertical, parálisis del VI nervio craneal izquierdo y signos de frontalización. En la tomografía yresonancia cerebrales se encontró hidrocefalia obstructiva por un tumor de la fosa posterior. La anatomía patológica reveló Astrocitoma Pilocítico grado I (WHO).

We previously described a divergent clinical and molecular presentation of hepatocellular carcinoma (HCC) in Peru. The present study aimed to further characterize the tissue features associated with this singular nosological form of HCC in order to gain insight into the natural history of the disease. We performed an exploratory analysis of the histology of both tumor and non-tumor liver (NTL) tissues from 50 Peruvian HCC patients, and compared with that of 75 individuals with non-HCC liver tumor or benign liver lesions as a baseline for NTL features. We complemented this approach with a transcriptome analysis in a subset of NTL tissue samples and also performed an ultra-sensitive hepatitis B virus (HBV) detection in liver tissues of the patients. Overall, results highlighted the low rate of liver parenchymal alterations in a young patient cohort (median age: 40 years old), despite a str...

Aim: Evaluation of features related to infiltrating immune cell level in glioblastoma. Methods: Tumor-infiltrating lymphocytes (TILs) through H&E staining, and TILs (CD3, CD4, CD8 and CD20) and macrophage (CD68 and CD163) levels through immunohistochemistry were evaluated through digital analysis. Results: CD68 (9.1%), CD163 (2.2%), CD3 (1.6%) and CD8 (1.6%) had the highest density. Higher CD4+ was associated with unmethylated MGMT (p = 0.016). Higher CD8+ was associated with larger tumoral size (p = 0.027). Higher CD163+ was associated with higher age (p = 0.044) and recursive partitioning analysis = 4. Women (p < 0.05), total resection (p < 0.05), MGMT-methylation (p < 0.001), radiotherapy (p < 0.001), chemotherapy (p < 0.001) and lower CD4+ (p < 0.05) were associated with longer overall survival. Conclusion: Macrophages are more frequent than TILs. Some subsets are associated with cli...
