Objective: studying the posterior side of the pubic symphysis (joint containing a fibrocartilaginous disc) in adult human corpses to find possible anatomical variations. Methodology: the posterior side of the symphyseal joint was dissected and its anatomical characteristics were evaluated. Fifty-three pubic symphyses (4 females and 49 males) were evaluated in an anatomic approach by making an incision in the abdominal-pelvic wall to reveal elements associated with the pubis. Results: macroscopic examination of the pubic symphysis revealed uniform, smooth posterior faces, except in two male cadavers. One of them had two, different sized, contiguous nodular protuberances which were vertically aligned on the posterior face of the symphysis disc whilst the other cadaver presented a border, in the form of a crest, also vertically orientated on the posterior face of such disc. Both protuberances so found had direct communication within the symphysis disc, like ampoules, with intra-articular liquid derived from the outlined disc's cavity. Conclusion: the nodulations and border described above could have corresponded to articular pathological alterations, such as pubic symphysis diastasis, but without being separated from the body of the pubis.
