Your Name & Date

2. Introduction
• • Definition of a lung mass (>3 cm)
• • Importance of accurate diagnosis
• • Brief overview of diagnostic approach

3. Benign vs. Malignant Causes
• • Benign: Infectious, inflammatory, vascular,
congenital
• • Malignant: Primary lung cancer, metastases

4. Infectious Causes
• • Tuberculosis
• • Fungal infections (Histoplasmosis,
Coccidioidomycosis)
• • Lung abscess

5. Inflammatory & Autoimmune
Causes
• • Sarcoidosis
• • Wegener’s Granulomatosis (GPA)
• • Rheumatoid nodules

6. Benign Neoplasms
• • Hamartoma
• • Lipoma
• • Fibroma

7. Primary Malignant Lung Tumors
• • Non-Small Cell Lung Cancer (NSCLC):
• - Adenocarcinoma
• - Squamous Cell Carcinoma
• - Large Cell Carcinoma
• • Small Cell Lung Cancer (SCLC)

8. Metastatic Lung Lesions
• • Common sources: Breast, colon, kidney,
melanoma
• • Radiologic features of metastases

9. Imaging & Diagnostic Workup
• • Chest X-ray & CT scan
• • PET scan
• • Biopsy techniques (Bronchoscopy, CT-
guided, Surgical)

10. Management Approach
• • Benign lesions: Observation, antibiotics,
surgery if needed
• • Malignant lesions: Surgery, chemotherapy,
radiation, targeted therapy

11. Conclusion
• • Summary of key points
• • Importance of a systematic approach
• • Next steps for evaluation
