# Pulmonary Pneumocytoma: A Benign Rarity Behind a Suspicious Nodule

## TL;DR

Pulmonary pneumocytoma is a rare benign lung tumor that can be mistaken for cancer, requiring careful diagnosis to avoid unnecessary treatment.

## Contribution

This paper presents a case emphasizing the importance of considering pneumocytoma in the differential diagnosis of lung nodules.

## Key findings

- Pneumocytoma was confirmed in a 40-year-old female via surgical resection and histopathology.
- The case underscores the need for multidisciplinary evaluation to prevent overtreatment.
- Pneumocytoma should be considered in the differential diagnosis of solitary pulmonary nodules in middle-aged women.

## Abstract

Pulmonary pneumocytoma is a rare benign tumor most often detected incidentally as a solitary pulmonary nodule. Although its radiological appearance is nonspecific, its histological complexity can mimic several malignant neoplasms, leading to potential overtreatment. We report a case of a 40-year-old female with a suspicious pulmonary lesion discovered during the evaluation of an unrelated oropharyngeal carcinoma. Surgical resection and histopathological analysis confirmed the diagnosis of pneumocytoma. This case highlights the importance of considering pneumocytoma in the differential diagnosis of solitary pulmonary nodules, particularly in middle-aged female patients. Early multidisciplinary evaluation is essential to avoid unnecessary radical treatment.
