No preventative measures for benign adnexal neoplasms are known at this time.
No complications are specifically associated with poromas. The surgical treatment of poromas can produce the same common complications (eg, infection, hemorrhage) associated with any minor surgical procedure.
The prognosis of poromas is favorable because the lesions have no known clinical significance. Even poromatosis (multiple poromas) is not known to be associated with other anomalies. The risk of malignant transformation of a poroma is minimal and is thought to be similar to that of normal skin.
