Variant 1: 59-year-old woman presented with a 1.5-cm left mid–labia majora lesion not approaching midline. Clinically, she had no palpable groin nodes. She underwent left modified radical vulvectomy and left sentinel node dissection. Pathology revealed a 2.1-cm squamous cell carcinoma on left labia majora with negative margins >1 cm, no LVSI, and 3-mm stromal invasion. 2 sentinel nodes were removed from left inguinofemoral region; both were negative.
Variant 2: 65-year-old woman presented with significant vulvar pruritus from a 2-cm lesion arising from the left labia minora and approaching the urethra. She had no urinary complaints. No palpable inguinal lymph nodes. CT pelvis was negative for any lymphadenopathy in the groins or pelvis. She underwent wide local excision and sentinel lymph node dissection. Pathology revealed 2.4-cm squamous cell carcinoma with a close margin (<2 mm) at the urethra, no LVSI, and 6-mm stromal invasion. Re-excision not possible without resection of the urethra. 2 left inguinal lymph nodes were removed, all negative.
Variant 3: 71-year-old woman with a painful 4-cm mass arising in the right midlabia. Clinically, she has a palpable right groin mass, left groin has no clinically palpable adenopathy. CT pelvis shows multiple enlarged lymph nodes in bilateral groins. The right mass appears to be 3 cm in size radiographically. No enlarged lymph nodes in the pelvis. She underwent right modified radical vulvectomy and bilateral lymph node dissection. Pathology revealed a 3.8-cm squamous cell carcinoma on the right labia majora with 1.2-cm stromal invasion, negative margins. The right inguinofemoral dissection revealed a conglomerate of lymph nodes measuring 3.2 cm with extracapsular lymph node extension and LVSI. The left groin dissection revealed 1 positive lymph node with an 8-mm tumor deposit. 6 additional lymph nodes were negative. The patient has 2+ right lower extremity lymphedema.
