Giant lobulated seborrheic keratosis at an unusual site.

ABSTRACT

Seborrheic Keratoses(SK) are common benign skin tumors of elderly occurring commonly on face, scalp, extremities, chest, back with genital and perianal sites being rare. Lesions are usually few millimeters to several centimeters, reaching pendulous proportions in areas of constant friction, especially in obese individuals. Though malignant transformation is rare, it is reported in irritated lesions, especially in flexures. An unusual case of giant lobulated seborrheic keratoses occurring in perianal area, without any evidence of malignancy on histopathology, in an otherwise healthy obese female is reported here.
