Summary
This study reports a rare case of lung adenocarcinoma with sarcomatous transformation in a 50-year-old male. Histological and immunohistochemical findings suggest a malignant spindle cell component arising from adenocarcinoma.
Area of Science:
- Oncology
- Pulmonology
- Surgical Pathology
Background:
- Lung adenocarcinoma is a common malignancy.
- Rare subtypes and transformations present diagnostic challenges.
Observation:
- A 50-year-old male presented with an abnormal chest X-ray.
- Transbronchial brushing cytology confirmed adenocarcinoma.
- Surgical resection revealed a tumor with spindle-shaped cells and adenocarcinoma islands.
Findings:
- Histological examination showed a predominant spindle cell component.
- Immunohistochemistry revealed vimentin, keratin, and epithelial membrane antigen positivity in spindle cells.
- These findings suggest sarcomatous transformation of adenocarcinoma.
Implications:
- This case highlights a rare variant of lung adenocarcinoma.
- Accurate diagnosis is crucial for appropriate treatment strategies.
- Further research into sarcomatous transformation mechanisms is warranted.
