[Acanthosis nigricans over the face revealing primitive bronchial adenocarcinoma: about a case].

We here report a case of bronchial cancer revealed by acanthosis nigrigans affecting the face. This rare mode of revelation may precede diagnosis of underlying neoplasia by several months . This study highlights the importance of suspecting primary lung cancer in patients with acanthosis nigrigans.

Prevalence and risk factors for latent tuberculosis infection among healthcare workers in Morocco.

Increased prevalence of latent tuberculosis infection (LTBI) has been observed among high-risk populations such as healthcare workers (HCWs). The results may depend on the method of LTBI assessment, interferon-gamma release assay (IGRA) and/or tuberculin skin test (TST). Here, we investigated the prevalence and risk factors for LTBI assessed by both IGRAs and TST in HCWs living in Morocco, a country with intermediate tuberculosis (TB) endemicity and high BCG vaccination coverage.

[A rare infectious etiology of COPD exacerbation].

Chronic obstructive pulmonary disease (COPD) is a common respiratory disorder. Its exacerbation is infectious in more than half of the cases: with viral priority, while parasitic causes remain exceptional. In this work, we report a case of a COPD exacerbation caused by a visceral leishmaniasis (VL) complicated by a macrophage activation syndrome in an adult living in a Moroccan non-endemic region for this of leismaniasis form.
