F ibroepithelial polyps or acrochordons are benign tumors of mesenchymal and ectodermal origin. They frequently occur in places where skin folds are present. Generally, their size does not exceed 5 millimeters. However, a case with a 42 centimeters long FEP has been reported in the literature. [1] There are different opinions about how FEPs reach these sizes and what triggers the growth. It is stated that the sensitivity of epithelium to hormones and hormonal changes may be the cause of the growth of FEPs, which are located in the genital tract and reached huge sizes. [2] It is also remarkable that FEPs located in this area are seen more frequently in women and in reproductive age. [3] It is not known exactly what triggered the growth of the FEPs that are located in other locations and reached huge sizes. However, a positive correlation between obesity, insulin resistance and FEP growth has been proposed. [4][5][6] Our case was unique concerning the FEP location. We did not find a similar case in terms of location and size in the literature. Our patient also had a ventriculoperitoneal shunt for six years due to idiopathic hydrocephalus. The shunt was 2 centimeters away from FEP. It may be thought that the foreign body reaction in this area may be an effect on FEP growth. In this report, we aimed to present our approach to a giant FEP and to examine the factors that cause FEP growth.
