BACKGROUND: The sentinel lymph node concept is attractive in vulvar cancer because of the potential to avoid the morbidity associated with formal groin dissection.
CASE: An 84-year-old patient with a T2 carcinoma of the anterior vulva underwent surgery including bilateral sentinel node excision after identification with technetium-labeled nanocolloid. Frozen section histology showed a tumor deposit <1 mm in diameter in a left groin node whereas four nodes in the right groin were apparently negative. Completion lymphadenectomy was performed only for the left groin. Final histology including serial sectioning showed a micrometastasis in one of seven nodes from the right groin; no further treatment was given. Sixteen months postoperatively the patient developed a recurrence in the right groin; the left groin was free of tumor.
CONCLUSION: This case indicates that groins with a micrometastasis detected by sentinel lymph node excision require further treatment.
