Superficially invasive vulvar cancer with nodal metastases.

Seven patients with superficially invasive vulvar cancer and lymph node metastases are reported. Histology of the primary tumor does not seem to correlate reliably with its metastatic potential in any individual case, though "spray," pseudoglandular, and small cell carcinomas may be particularly aggressive lesions. While wide local excision seems to be adequate treatment for the primary lesion, it is recommended that for lesions with greater than 1 mm of stromal invasion, bilateral inguinal-femoral lymphadenectomy should be performed for midline lesions, and at least ipsilateral inguinal-femoral lymphadenectomy should be performed for lateralized lesions.
