| Feature | Typical Carcinoid | Atypical Carcinoid |
|---|---|---|
| Grade | Low-grade (well-differentiated) | Intermediate-grade (moderately differentiated) |
| Mitotic activity | ≤1 mitosis per 2 mm² | 2–10 mitoses per 2 mm² |
| Necrosis | Absent | Present (focal necrosis) |
| Aggressiveness | Indolent | More aggressive |
| Prognosis | Better | Worse than typical carcinoid |
| Metastatic potential | Low | Higher (but less than small cell carcinoma) |
| Location | Central or peripheral lung | Often central |
| Association with smoking | Not strongly associated | Not strongly associated |
| Immunohistochemistry | Chromogranin A, Synaptophysin, CD56 | Chromogranin A, Synaptophysin, CD56 |
Carcinoid syndrome (e.g., flushing, diarrhea) is rare in pulmonary carcinoids and more typical with GI carcinoids.
