Abstract

Background Primary mediastinal large B-cell lymphoma (PMBCL) and Hodgkin nodular sclerosis (LHNS) lymphoma was the most common lymphomas involved the mediastinum. These two lymphomas had similar histopathological features. The purpose of this study was to analyzed clinical data, histopathological characteristics, and immunohistochemistry (IHC) profiles on PMBCL and LHNS. Methods This is a retrospective study. Data was collected from archive of Anatomical Pathology Department, Faculty of Medicine, Universitas Indonesia/Cipto Mangunkusumo Hospital in 2014-2020. The data collected included clinical data, hematoxylin-eosin (HE) and IHC slides and were reassessed by the researcher and supervisor. The histopathological characteristics data was analyzed statistically using statistical package for the social sciences version 25.0 with Chi-Square test. Results PMBCL and LHNS have similar histopathological features, included the characteristics of tumor cells and infiltration of many fibrosis and inflammatory cells, but difference in architecture, tumor cell types, clear cytoplasmic tumor cells, inflammatory cell and fibrosis types, with p value <0.001. The characterized differences of PMBCL showed diffuse architecture, some cells with RS-like cell structure, clear/pale cytoplasm, lymphocyte cell infiltration, and compartmental fibrosis. Whilst, LHNS showed nodular architecture, Reed Sternberg cells, mixed inflammatory cell infiltration, and band-like fibrosis. PMBCL showed CD20, PAX5, MUM1 strongly positive, CD30 weakly positive, and CD15 negative, while LHNS showed negative CD20, CD30 and MUM1 strongly positive, PAX5 weakly positive, and CD15 positive.

Abstract

BackgroundMyeloproliferative neoplasm (MPN) is a neoplasm characterized by the proliferation of one or more myeloid cells and their derivatives. The limitations of molecular examination in Indonesia make the diagnosis of MPN based on clinical and histopathological examination very crucial. The aim evaluate the clinicopathological profile of primary myelofibrosis (PMF), polycythemia vera (PV), and essential thrombocythemia (ET) and identify the typical morphological characteristics of bone marrow biopsy.MethodsA retrospective study of cases diagnosed with MPN was conducted at the Department of Anatomic Pathology FMUI/RSCM in 2015-2019. Clinical data and evaluation of bone marrow morphology consisting of cellularity, erythroid myeloid ratio, cluster and megakaryocyte morphology, blast cells, fibrosis, osteosclerosis, and sinus dilatation were analyzed.ResultsA total of 172 cases were diagnosed as MPN BCR-ABL1-negative (PMF: 74; ET: 56; PV: 42). On routine blood examination, there was an increase in hemoglobin (Hb) and hematocrit (Ht) in PV, a decrease in Hb in PMF and an increase in platelets in ET (p<0.001). Splenomegaly is mostly found in PMF. Myeloid erythroid ratio was decreased in PV, normal in ET and increased in PMF (p<0.001). Megakaryocytes were arranged in loose clusters in 88.1% of PV cases and 96.4% of ET, dense clusters were found in 91.9% of PMF cases. Staghorn-like megakaryocytes were found in all ET cases and bulbous/cloud-like megakaryocytes were found in 97.3% of PMF cases. Most cases of PV (90.5%) and all cases of ET showed pre-fibrotic bone marrow (grade 0-1), while 77% of PMF cases showed fibrosis grade 2-3.ConclusionIn diagnosing PV, ET, and PMF, correlation between clinical data, laboratory, and bone marrow histomorphological evaluations, especially cellularity, myeloid:erythroid ratio, cluster and megakaryocyte morphology, degree of fibrosis, osteosclerosis, and sinus dilatation is required.

Abstract

Background The presence of tumor-infiltrating lymphocytes (TILs) has been widely explored as one of the factors that can affect the success of immunotherapy in various cancers. This study aims to investigate the TILs in various types of thyroid carcinoma (TC) and its association with the aggressive histopathological type compared to the less aggressive histopathological type of TC. Methods The population covered by this retrospective study was TCs diagnosed at the Department of Anatomic Pathology, Faculty of Medicine, University of Indonesia/Dr. Cipto Mangunkusumo National Central General Hospital, period 2015-2019. The research sample was divided into group of TCs with aggressive histopathological type and less aggressive histopathological type with a total of 25 samples for each group. TILs was calculated in 10 high power fields (HPF) with 400 kali magnification. The analyses were conducted using Mann-Whitney and Kruskal Wallis test. Results TILs count was found with a median value of 43 (3-660) in the aggressive histopathological group and 36 (9-387) in the less aggressive histopathological group (p:0.96, CI:95%). The highest TILs was found in anaplastic thyroid carcinoma (ATC) and papillary thyroid carcinoma (PTC) with anaplastic components. TILs count was also found with a median value of 17.5 (3-75) in male and 48 (9-660) in female (p:0.02, CI:95%). Conclusion There was no significant association between TILs and histopathological types of TC (aggressive and less aggressive). However, there is a tendency for high TILs in ATC and PTC with anaplastic components. There is also a significant difference in TILs between male and female gender.
