RESUMEN
A 48 years old man presented with subacute intestinal obstruction resulting from an intraluminal colorectal mass. He underwent partial colectomy. Histological diagnosis of mucinous adenocarcinoma with focal areas of heterotopic ossification was made. Although the presence of heterotopic ossification has no known prognostic implication in colorectal carcinoma, however, it is important that both radiologist and pathologist be aware of this phenomenon as distinct from carcinosarcoma that has poorer prognosis. From the available literature reviewed and to the best of our knowledge, this is the first reported case of mucinous colorectal carcinoma with heterotopic ossification in Saudi Arabia
RESUMEN
A 25-year-old male Nigerian undergraduate who had earlier been treated with praziquantel for schistosomal epidydymitis presented with clinical features of pyelonephritis, and radiological appearances of bilateral hydroureteronephrosis with fibrosis of lower ureters. Surgical resection of the ureters, Boari flap and Psoas hitch reconstruction were done. The histology of the resected ureters proved schistosomiasis. He was subsequently treated with praziquantel and artemether. This case highlights the insidious nature of schistosomiasis infection, possibility of progression of primary infection with complications or probable reinfection in a previously treated individual. In any case, surgical intervention may be necessary in those who present late with severe ureteric stricture and also to prevent progressive renal damage
