On histopathology,<unk> s are generally lined by simple cuboidal epithelium as shown. However, they may have fallopian tubal epithelium or focal papillary projections. Most<unk> s are small and asymptomatic. Typical sizes reported are 1 to 8 cm in diameter. PTCs may be found at surgery or during an imaging examination that is performed for another reason. Larger lesions may reach 20 or more cm in diameter and become symptomatic exerting pressure and pain symptoms in the lower abdomen. Large<unk> s can lead to torsion of the adnexa inflicting acute pain. Prior to surgery, PTCs are usually seen on ultrasonography. However, because of the proximity of the ovary that may display follicle<unk> s, it may be a challenge to identify a<unk>  as paratubal or<unk> .
