Pigmented Basal Cell Carcinoma of Vulva: An Unusual Clinico-histomorphological Finding

Basal cell carcinoma is the most common skin malignancy, often seen in elderly patient with the sun exposed areas, accounting for approximately 70-80% of cutaneous cancer. It can occur in sun protected areas among them genital involvement is very rare and it accounts for less than 1% of all cases. As the vulvar BCC is very rare accounting about less than 5% of all vulvar neoplasm, most of the time it is misdiagnosed due to its nonspecific characteristics. We report a case of vulvar basal cell carcinoma which was misdiagnosed for 2 years in a 39 years old middle-age female patient. Vulvar basal cell carcinoma is usually diagnosed late due to its asymptomatic and slow growth pattern. The cause is unknown, but chronic vulvar irritation is important factor that gives clue to early diagnosis.
