**Note 3:** Basal and squamous cell carcinomas of the skin of the vulva are coded to C519 and are reportable; basal and squamous carcinomas of the skin of the perineum would be coded to C445 and would not be reportable.
**Note 4:** Isolated tumor cells (ITCs) are defined as single tumor cells or small clusters not greater than 0.2 mm, usually detected by immunohistochemical (IHC) or molecular methods. ITCs do not usually show evidence of malignant activity (e.g., proliferation or stromal reaction).
* Lymph nodes with ITCs only are **not** counted as positive nodes for Summary Stage
