A 65-year-old woman presents with postmenopausal vulvar pruritus, a raised, whitish hyperkeratotic lesion on the right labium majus, and an enlarged right inguinal lymph node. Biopsy confirms squamous cell carcinoma of the vulva. Staging workup reveals a 3.5 cm lesion with unilateral inguinal nodal involvement. According to FIGO staging, this is classified as:
- A Stage II
- B Stage IIIA ✓
- C Stage IIIB
- D Stage IVA
Correct answer: B. Stage IIIA
Explanation
FIGO Stage IIIA vulvar carcinoma is defined as any size tumour with one or two inguinal-femoral lymph node metastases. A lesion >2 cm (Stage II involves tumour >2 cm or with extension to adjacent perineal structures with negative nodes) combined with positive unilateral nodal involvement places this patient in FIGO Stage IIIA. Stage IIIB involves three or more positive nodes or two or more nodes with extracapsular spread.
