Abstract

Mixed squamous cell and glandular papilloma of the lung is an extremely rare benign epithelial tumor showing a mixture of squamous and glandular epithelium. Here, we report a case of mixed squamous cell and glandular papilloma that presented as a solitary nodule in the left lower lobe of a 64-year-old woman. Chest computed tomography demonstrated a lobulated mass in the basal segment of the left lower lobe. The patient underwent a lobectomy under the suspicion of lung malignancy. The histopathological diagnosis was mixed squamous cell and glandular papilloma.

Keywords: Lung neoplasms; Mixed squamous cell and glandular papilloma; Papilloma.

(A) Chest X-ray shows a nodule (arrow) in the left lower lung field. (B) Chest computed tomography scan shows 4×3 cm lobulated nodule in the basal segment of the left lower lobe. (C) Further, a positron emission tomography scan shows increased uptake (maximal standardized uptake value of 6.7) in these nodular lesions.

Pathological findings. (A) Mixed squamous and mucin-secreting glandular epithelium covered the fibrovascular cores (H&E, ×20), (B) mucin-secreting glandular epitheliums (H&E, ×1,000), and (C) acantholytic squamous epithelial nests (H&E, ×1,000), and immunohistochemical staining.
