A 61 year-old female presented with @entity490 , @entity548 , mucus discharge, tenesmus and @entity1142 . Rectal examination and proctoscopy demonstrated @entity850 at 5 cm from the anal verge. Transrectal ultrasonography detected a capsulated lesion as a mesenchymal @entity5 . Computed tomography and endorectal magnetic resonance detected a mesenchymal lesion in the lower-middle rectal thirds. Serum TPA, GICA, SCC and CYFRA were pathological. At surgery the @entity5 was fixed to the levator ani muscle with rectal folding. Frozen sections of the levator ani muscle biopsies revealed @entity5 . Abdominoperineal resection was performed. The @entity75 was @entity48532 at 9 cm from the dentate line (pT4 pN0; Ki67 35%; @entity2279 181 vessels/mm2). Adjuvant radio-chemotherapy was performed. The @entity1 is alive and disease free at 19 months. Extra-anal cloacogenic @entity5 are an unusual finding. Perhaps cloacal cells were originally present in the rectal wall, but secondary rectal involvement by cloacal remnant from the levator ani muscle cannot be excluded.

An unusual location of XXXX .
