Cutaneous leishmaniasis (CL) is the most frequent form of leishmaniasis. The auricle is an extremely rare site for CL in the Old World. Auricular CL may be mistaken for other entities, such as relapsing polychondritis (RP). Here we report a pediatric case of Old World auricular CL mimicking RP in a child successfully treated with intralesional liposomal amphotericin B.

Invasive ductal carcinoma (IDC) is a major type of breast cancer. The utilization of inhibitors targeting histone methyltransferases introduces novel therapeutic avenues for the treatment of cancer. Immunohistochemistry, Western blot, and reverse transcription quantitative polymerase chain reaction experiments were applied to assess the levels of EHMT2 in IDC and adjacent tissues.

The Hippo pathway and its transcription co-activator YAP play a critical role in the regulation of cell proliferation, apoptosis and the control of organ size. In the past several years, YAP has been found to be expressed in various human cancers, however, its expression in Nasopharyngeal Carcinoma (NPC) remains unstudied. In this report, we found that YAP was overexpressed in human NPC tissues, and its expression was also significantly higher in five NPC cell lines when compared with the nasopharyngeal epithelial cell line NP69 (P < 0.

Background: Anaplastic lymphoma kinase (ALK)-positive primary CNS anaplastic large cell lymphoma (ALCL) is an extremely rare pediatric malignancy. Its radiological appearance often mimics infectious or glial lesions, complicating diagnosis and delaying treatment.
Observations: The authors report the case of a 10-year-old immunocompetent female who presented with absence seizures and vomiting.

Background And Objectives: Neuroimaging findings in immune effector cell-associated neurotoxicity syndrome (ICANS) have not been systematically described. We created the chimeric antigen receptor (CAR) T-cell Neurotoxicity Imaging Virtual Archive Library (CARNIVAL), a centralized imaging database for children and young adults receiving CAR T-cell therapy. Objectives of this study were to (1) characterize neuroimaging findings associated with ICANS and (2) determine whether specific ICANS-related neuroimaging findings are associated with individual neurologic symptoms.

Acute myeloid leukemia (AML) with rearrangement of the mixed lineage leukemia gene express MLL-AF9 fusion protein, a transcription factor that impairs differentiation and drives expansion of leukemic cells. We report here that the zinc finger protein GFI1 together with the histone methyltransferase LSD1 occupies the promoter and regulates expression of the lncRNA ELDR in the MLL-r AML cell line THP-1. Forced ELDR overexpression enhanced the growth inhibition of an LSD1i/ATRA combination treatment and reduced the capacity of these cells to generate leukemia in xenografts, leading to a longer leukemia-free survival.
