Bilateral V-Y flap for a perianal basal cell carcinoma: A case report.
BACKGROUND
Basal cell carcinomas are rare in non-sun-exposed skin, and are even rarer in the perianal region. Alertness to the unusual occurrence of this tumor at perianal site, with understanding of its clinical course, can prevent delay in its diagnosis and morbid aggressiveness in the management of the disease.


METHODS
A 93 year old female, referred to our hospital because of a three month bleeding ulcerative lesion, with a diameter approximately of 4.5×3.2cm, located in the perianal region.


CONCLUSIONS
Tumors of the anus and perianal are infrequent neoplasms of the digestive tract. There are many diseases that can be confused with this diagnosis and it is commonly delayed because the tumor is rarely thought of in this particular cutaneous topography. Suspicion and early diagnosis, give the opportunity for a timely and appropriate treatment and also prevent tumor extension.


CONCLUSIONS
Treatment modalities include early wide local excision to clear margins, ensuring further local recurrence and distant metastasis. The use of local V-Y advancement fasciocutaneous flaps may be another valid option for the reconstruction of perianal skin defects, with less morbidity than other flaps described in the literature.
