Buruli ulcer: An epidemiological update from Japan.

Japan is one of the rare non-tropical countries with documented cases of Buruli ulcer (BU). Mycobacterium ulcerans subsp. shinshuense has been identified as the causative agent. The first report of BU in Japan dates back to 1982, with sporadic reports thereafter. Recently, the number of cases has been on the increase, and 50 cases (57.7%) are from the past decade alone, out of a total of 87 cases reported to date. Japan's well-developed healthcare facilities play a crucial role in enabling detailed investigations and providing appropriate treatment for patients, contributing to a favorable prognosis. However, the rarity of the disease results in lack of awareness among healthcare professionals, leading to frequent delays in diagnosis. This article aims to offer an updated overview of BU cases in Japan and to raise awareness of BU among dermatologists and other healthcare professionals in a non-endemic setting.

Case Report: Cutaneous Leishmaniasis-A Hidden Disease in Côte d'Ivoire.

Cutaneous leishmaniasis (CL) is classified as one of the skin-related neglected tropical diseases by the WHO. There have been limited reports of CL in Côte d'Ivoire, with fewer than 20 cases reported from Côte d'Ivoire in the literature since 1967, when it was first identified. Here, we report a case of CL originating in Côte d'Ivoire that we diagnosed during our active case finding activity in the Zounan Hounien District. The patient, a 15-year-old male, presented with multiple noninflammatory skin lesions on the face and trunk that had progressed from nodular to ulcerated lesions over the previous 3 months. Concurrent symptoms included fever, chest pain, cough, and malaise. Investigations for infectious diseases such as HIV and tuberculosis returned negative results. Histopathological analysis of a skin biopsy specimen from the nasal base demonstrated the presence of Leishman-Donovan bodies, confirming a diagnosis of CL. Although treatment with intralesional meglumine antimoniate (Glucantime) injections was intended, the drug could not be administered because the patient unfortunately died shortly after our consultation visit. Because of the rarity of CL in Côte d'Ivoire, awareness remains low, resulting in delayed diagnosis and treatment. Urgent strategies to improve awareness of CL among clinicians practicing in Côte d'Ivoire is required, first to appropriately diagnose and treat CL and second to generate epidemiological data of adequate quality.

A case of recurrent erythema induratum of Bazin in a patient with myelodysplastic syndrome.

We describe a case of erythema induratum of Bazin (EIB) that presented recurrently on the extremities during treatment with anti-tuberculosis medications. The anti-tuberculosis medications were effective, so they were continued despite the occurrence of the EIB lesions, and those lesions disappeared 5 months after first appearing. EIB is currently considered a multifactorial disorder with many different causes, with tuberculosis being an example, and it is thought to be a hypersensitive immune response to Mycobacterium tuberculosis. The clinical manifestations may fluctuate depending on the immune response of the host. Our patient was affected with myelodysplastic syndrome, and we believe that this was a major factor that interfered with a normal immune response. This case illustrates the importance of providing intensive anti-tuberculosis treatment from the start, and in cases where EIB co-presents, to continue this treatment until the end, in order to prevent relapse.
