Staging and TNM Classification of MF
| Stage . | T . | N . | M . |
|---|---|---|---|
| IA | T1: eczematous lesions, plaques: <10% of body surface | N0: no palpable lymph node; histologically no evidence of MF | M0 |
| IB | T2: eczematous lesions, plaques: >10% of body surface | N0 | M0 |
| IIA | T1/T2 | N1: palpable lymph node; histologically no evidence of MF | M0 |
| IIB | T3: tumors (more than 1) | N0/N1 | M0 |
| III | T4: erythroderma | N0/N1 | M0 |
| IVA | T1-T4 | N2: no palpable lymph node, histological MF N3: palpable lymph nodes, histological MF | M0 |
