Background: Lung cancer is the most frequent cause of cancer-related death worldwide. For adenocarcinomas, histological subtyping is typically performed (e.g. lepidic, acinar, papillary, micropapillary, and solid), as suggested by the World Health Organization. Among these, micropapillary carcinoma has been a focus of significant research in recent years, as it is the newest subtype and has the worst prognosis. Herein, we summarize the most relevant findings of this morphological variant in detail with anecdotal experience and a review of the published literature.

Among the different types of bronchial asthma, the allergic one is certainly the most easily found. Allergic asthma is characterized by the presence of IgE antibodies called “reagine”, responsible for triggering respiratory allergic crises in the presence of perennial or seasonal specifi c allergens.

Background: The existence of COPD and heart failure in elderly population adds additional morbidity and mortality risk than if those with only one of the two comorbidities. The aim of the current metaanalysis was to explore the effect of COPD on heart failure patient in terms of all-cause mortality, cardiac mortality and recurrent heart failure hospitalization.

Lung cancer continues being a serious cause of death in developed countries with an increase in its incidence in recent years. According to the above, it is not uncommon to think that new techniques are being investigated to facilitate diagnosis, as well as its staging.

Foreign body aspiration is not very common in adults, clinically, patients either present with acute respiratory failure which require immediate intervention or with recent onset of symptoms, like wheezing, breathlessness, coughing, and expectoration. Occasionally, a forgotten or incidental foreign body may get detected on a chest radiographs which are obtained for unrelated reasons or during bronchoscopy. Identifi cation of occult foreign body aspiration often requires a high index of clinical suspicion, especially in those who present without a history of aspiration.
