The case report by Maranhão et al., published in 2020(1), addresses an immunocompetent adult individual with a clinical history of facial lesion and latent pneumonia, who was misdiagnosed with paracoccidioidomycosis. The patient was referred to a hospital complaining of facial lesions that appeared two months before, as well as persistent headache and night fever. According to his morbid history, he affirmed to work in a region with many pigeons, where he suffered a nose lesion with ceramic material. Ten years ago, he presented a wound that did not heal, constant cough and fever for a period of one month and 20 days(1). As the patient was initially misdiagnosed, it is essential to validate and understand the importance of differential diagnoses.
By analyzing the history of an individual with complaints of prolonged cough and fever for nearly two months in association with the current condition, it is possible to consider a differential diagnosis of tuberculosis, since Mycobacterium tuberculosis primarily affects the lung, and may progress to other organs such as the central nervous system and the skin. In the case reported(1), the patient sought a dermatologist for a skin complaint, who, based on his clinical condition, would reinforce the possibility of tuberculosis. However, cutaneous involvement by tuberculosis is a challenging diagnosis due to the great clinical, histopathological, and immunological variations and the difficulty in obtaining microbiological confirmation(2).
