Deceptive Pseudotuberculous Presentation of a Pulmonary Lepidic Adenocarcinoma.

Misleading presentations of lepidic adenocarcinomas (ADC) often lead to diagnostic delays, potentially reducing the chances of curative treatment. We report a case of mucinous lepidic ADC that mimicked pulmonary tuberculosis and was diagnosed at a late stage. The tumor showed no epidermal growth factor receptor (EGFR) expression or anaplastic lymphoma kinase (ALK) rearrangement and was characterized by bilateral pulmonary involvement without distant metastases. Through this case, the authors emphasize the need to consider lepidic ADC in cases of chronic pulmonary consolidation, despite atypical radio-clinical presentations that may be encountered in routine practice.
