Question Category:

Pathology

Correct Answer:

Granulation tissue

Description:

She has a urethral caruncle, which is most common in postmenopausal women as a result of urethral prolapse with atrophy from decreased estrogen. Topical estrogen creams and anti-inflammatory agents may shrink the lesion. It is not an infectious process, so multinucleated cells (herpes simplex virus) or plasma cell infiltrates (syphilis) are unlikely. It is not malignant or premalignant. Lichen sclerosus occurs at this age, but not produce a mass lesion.
