Mercell cell carcinoma is classified into 3 subgroups: trabecular, intermediate, and small cell.
Classification
Histologically, MCC has been classified into three distinct subtypes:[1][2]
| Subtype | Pattern | Histology studies |
|---|---|---|
| Trabecular type | Classic pattern |
|
| Intermediate type | Solid pattern |
|
| Small cell type | Diffuse pattern |
