It takes place hundreds of times in a woman’s lifetime, manifesting as vaginal expulsion of blood mixed with cellular debris for a period of several days. The aim of this work is to present a case of en bloc endometrial desquamation in a teenage patient using combined oral contraception. Several mechanisms are proposed, although further studies are needed to better understand this extremely rare phenomenon.engEn bloc endometrial desquamationEndometrial/physiologyEndometrial self-repairEndometriumMenstruationMAC GINjournal articleDOI: 10.36205/trocar2.2023004
