Retrorectal and presacral tumors a clinicopathologic study

Neoplasms in the retrorectal or presacral area are uncommon. In this work we aimed at studying the cases of retrorectal or presacral tumors admitted to our institute in the last four years by H and E stain, immunostain and electron microscopy with review of the literature. Twenty nine patients are included in this study, having variable lesions comprising 10 congenital, 2 neurogenic, 1 osseous, 4 soft tissue tumors, 5 multiple myeloma and 7 metastatic lesions. Difficult cases were studied by immunostain and / or electron microscopy. Both techniques proved to be highly specific in diagnosing equivocal cases and determining the cell of origin

Clinicopathological and sonographic correlation of the pre-operative and the operative findings in undescended testis

Twenty -six cases of undescended testes were studied in a prospective way in a period from January 1998 to June1999. The age ranges between 2 months and 12 years with a mean of 4 years and a peak incidence of 4 years. The site of the undescended testis was right side in 14 cases, left sided in 6 cases and billateral in 6 cases. The clinically palpable testes were in 16 cases and impalpable in 10 cases. Associated hernia was present in 22 cases, and associated anomalies were present in one case as transverse [paradox] ectopia of the testis. Ultrasound diagnosis revealed positive testes in 22 cases and negative in 4 cases. The sonographer gave no inconclusive result. At exploration, testes were found in all cases except for 1 case, which proved to be anorchism. Out of the 22 positive cases of ultrasound all cases were recovered surgically. Out of the 4 cases of negative ultrasound, three were found at different locations and fixed in the scrotum. Fidelity of ultrasound diagnosis in this series proved to be 23 cases [22 positive and 1 negative] out of 26 with a score of 88.4%
