This study aims to identify the most sensitive colorimetric test for assessing intracellular drug susceptibility of Leishmania tropica to conventional antileishmanial drugs. To this end, the efficacy of four colorimetric methods-MTT, XTT, MTS, and WST-8-was compared using reference L. tropica promastigotes.

Kaposi sarcoma is a low-grade vascular neoplasm linked to the human herpesvirus 8, with the AIDS-associated epidemic variant being the most common and aggressive. Although Kaposi sarcoma more commonly affects the cutaneous tissues, lymph nodes, and visceral organs, it can also be present in ocular and ocular adnexal tissues. We report a case of a 58-year-old Indo-Caribbean woman living with AIDS who presented with a large upper eyelid mass that was clinically diagnosed as Kaposi sarcoma.

This case series highlights the complexity of sarcoidosis-like reactions (SLRs) during cancer treatment, specifically in patients receiving immunotherapy or targeted therapies for melanoma. SLRs can either mimic disease progression or present as part of the clinical manifestation, making diagnosis and treatment challenging. Our study reviewed the medical records of 31 patients who were candidates for postoperative treatment between June 2022 and June 2024.

Background: Cutaneous Leishmaniases (CL), highly endemic in Africa and Mediterranean region, are caused by different Leishmania parasite species. Accurate species identification is crucial for effective diagnosis, treatment, and control of these diseases, but traditionally relies on DNA-based methods. High Resolution Melting analysis PCR (HRM PCR) provides rapid results and precise differentiation based on nucleotide variations.

Objective: To describe presentation, treatment and outcome of immune checkpoint inhibitor (ICI) associated-vasculitis in cancer patients in a multicentre study.
Methods: Thanks to the ImmunoCancer International Registry (ICIR), a multidisciplinary network focused on the research of the immune related adverse events related to cancer immunotherapies, patients presenting with a clinical and/or radiological suspicion of vasculitis, and histological evidence of vasculitis after being exposed to ICIs were retrospectively identified.
Results: Twenty eight cases were identified in the ICIR registry.
