ABSTRACT

Lung cancer is the type of cancer with the highest mortality in the whole world. For a cell to become cancerous it needs to undergo through several genetic mutations; which occur due to multiple predisposing factors. That is why in this type of cancer it is more common in smokers and patients over 40 years old; having less incidence in young patients. Clinical case: We present a case of a 23-year-old male patient referred from a first-level hospital duo to diagnoses of upper gastrointestinal bleeding + constitutional syndrome that were difficult to manage. Exams were made evidencing described later. Having a torpid evolution adding hemoptysis and signs of respiratory failure, refusing to perform a biopsy, eventually dying from multiple complications; relatives accept a post-mortem biopsy finding invasive non-mucinous adenocarcinoma. Conclusions: In the present case we found a patient in an advanced stage with a highly aggressive tumor as is common in these cases. The erroneous interpretation of the clinical case in the initial stages and the lack of importance on the part of the patient leading to a late diagnosis; although if we make an opportune diagnosis the oncological treatment is poor with a low survival.
