Prostate gland metastasis as a late relapse of rectal adenocarcinoma

We present a case report of a 49 year old patient with a known history of rectal adenocarcinoma treated with extended abdominal perineal resection. After five the patient was diagnosed with metastases to the prostate gland. This case stands out not only due to the infrequency of an onset of a colorectal tumor in the prostatic gland but also the late onset of the tumor. In these cases the differential diagnosis between a metastatic tumor and a primary urologic tumor is difficult due to similar morphology and histology, making the CDX-2 immunohistochemical maker expression an important tool to define the histopathology of the tumor.

Obstructive jaundice secondary to a pseudoaneurysm of the superior mesenteric artery

Superior mesenteric arteries pseudoaneurysms are rare entity, usually asymptomatic but they can appear as an abdominal pain, throbbing mass or shock, being jaundice an exceptional type of presentation. Diagnosis is made by imaging tests (CT) and currently the endovascular approach is the most widespread, reserving open surgery in selected cases. We describe the case of a patient with an 86mm SMA pseudoaneurysm with compression of the extrahepatic bile duct.

Rectal inflammatory stenosis secondary to Chlamydia trachomatis: a case report

The rectal inflammatory originated strictures constitute a rare cause of intestinal obstruction. We present a 30-year-old male patient with a history of HIV and protctitis caused by Chalmydia trachomatis and HSV-2, in which develops a low intestinal obstruction refractory to medical treatment. Surgery was performed with good clinical evolution. The medical treatment constitutes the fundamental basis of the therapy in these patients. Despite that, when fibrotic stenoses are not treatable medical or endoscopically, they often require surgical treatment. We must pay attention to the proctitis infectious diseases as a cause of rectal stenosis, especially by Chlamydia trachomatis, and assess surgical option in refractory cases.
