Acute appendicitis due to metastasis of prostatic carcinoma is very rare, and only five cases of metastasis of prostatic carcinoma are described in the literature. We report the case of a 73-year-old man with a history of an adenocarcinoma of the prostate with multiple bone metastases. The patient was admitted to the emergency department with symptoms and signs of an acute appendicitis which was confirmed by computed tomography (CT). Laparoscopic surgical exploration was performed, affirming an acute appendicitis with a suspicious lesion in the appendix base. Due to the location of the lesion, an ileocecectomy was performed. Histopathological and immunohistochemical examinations of the specimen showed an extrinsic infiltration of the appendix by adenocarcinoma metastasis expressing the prostate-specific antigen (PSA). These results confirmed an acute appendicitis caused by metastasis of prostatic adenocarcinoma.

Introduction Rectal prolapse is the complete protrusion of the rectum through the anal canal, incarceration rarely complicates rectal prolapse. Even more rarely, it becomes strangulated and gangrenous, necessitating emergency surgery. Case presentation We present the first reported case of strangulated acute rectal prolapse as the first manifestation of rectal prolapse. The patient was a 26-year-old man who presented with a 20×6 cm semi-spherical mass extra-anally. Rectosigmoidectomy with sacral rectopexy was performed, resecting 20 cm of the incarcerated rectum and sigmoid colon. The postoperative course was uneventful with a good final result after colostomy closure and continuity restoration. Conclusion The successful treatment of this patient illustrates the value of surgery in this difficult and unusual case scenario of rectal incarceration.

Introduction Rectal prolapse is the complete protrusion of the rectum through the anal canal. Incarceration rarely complicates rectal prolapse. Even more rarely, it becomes strangled and gangrenous, necessitating emergency surgery. Case presentation We report an extremely rare case of strangulated acute rectal prolapse as the first manifestation of rectal prolapse. The patient was a 26-year-old man who presented on admission a 20 × 6 cm semispherical mass extra-anally. Rectosigmoidectomy associated to sacral rectopexy was performed with resection of 20 cm of the incarcerated rectum and sigmoid colon. The postoperative course was quite uneventful with an excellent final result after colostomy closure and continuity restoration. Conclusion The successful treatment of this patient illustrates the value of surgery in the difficult and unusual case scenario of rectal incarceration.
