Vulvar basal cell carcinoma (BCC) is rare, accounting for less than 5% of all vulvar neoplasms and less than 1% of all BCCs. Vulvar BCCs are usually diagnosed late because they are often asymptomatic and tend to grow at slow rates. They may be invasive and destructive if neglected or improperly treated. Nevertheless, they have a very low propensity for metastatic spread, but frequently recur after simple excision. We report a 78 year-old woman presenting with the complaint of painful vulvar ulceration and vaginal bleeding. The physical examination revealed a 3 × 2 cm indurated nodulo-ulcerative lesion involving the clitoris, both labia minora and left labium majus. The histopathology was consistent with the “solid type BCC” that invaded the subcutaneous tissue without lymph node metastasis. The patient underwent wide local excision with clitoral amputation and remained disease free at post-surgical follow-up after 18 months.
