Nodular Vasculitis: Retrospective Study of an Uncommon Disease in a Non-Tuberculosis Endemic Country with Focus on Treatment Modalities and Efficacy.

Introduction: Nodular vasculitis (NV) is a rare form of panniculitis primarily affecting middle-aged females, presenting as painful, sometimes ulcerated nodules on the dorsal lower legs. Erythema induratum of Bazin (EIB) is a form of NV and is considered a manifestation of cutaneous tuberculin hypersensitivity. This retrospective study aims to analyze demographics, clinicopathological findings, laboratory results, and treatment outcomes of NV in a non-TB endemic country.

Problems when diagnosing cutaneous leishmaniasis: a retrospective study analyzing clinical, histopathological and immunohistochemical features.

Background: Cutaneous leishmaniasis (CL) incidence in Switzerland is rising due to factors like migration and globalization. The aim of this work was to investigate CL frequency in Switzerland and identify clinical and histopathological difficulties in diagnosing CL in a non-endemic country.

Patients And Methods: This retrospective study evaluated the clinical and histopathological characteristics of all CL cases from two dermatopathology laboratories between 2000 and 2022.
