Randomized trial finds multifocal lepidic mucinous adenocarcinoma in a heavy smoker, suggesting complex diagnostic challenges.

The aim was to highlight the diagnostic challenges of lepidic mucinous adenocarcinoma, especially in patients with a history of smoking.
A 53-year-old woman with chronic obstructive pulmonary disease and extensive smoking history underwent imaging and bronchoscopy.
Comprehensive infectious workup was performed but negative, leading to a biopsy for diagnosis.
Biopsy revealed multifocal lepidic mucinous adenocarcinoma in the right upper and middle lobes.
Initial imaging mimicked chronic infection, delaying accurate diagnosis despite multiple antibiotic trials.

Heydari et al. (2026) studied this question.
