Adenocarcinoma of an ileostomy site with skin invasion: a case report.

A case is reported of an adenocarcinoma arising in an ileostomy site 32 yr after a staged proctocolectomy for ulcerative colitis. As in 2 of the 3 previously reported cases of Ileostomy carcinoma, a locally invasive tumor produced Ileostomy retraction and stenosis with peristomal pain and ulceration but no intestinal obstruction or metastatic spread. When an ileostomy requires late revision for inflammatory changes, careful pathologic examination of the entire resected stoma and surrounding skin is essential.

Metastatic tumors of spermatic cord

A case of metastatic carcinoma to the spermatic cord is presented. The previous 12 cases documented in the literature are reveiwed. In the majority of cases the primary tumor occurred in the gastrointestinal tract with metastasis to the spermatic cord by retrograde lymphatic flow.

Regeneration of Liver and Kidney

Compensatory growth in response to injury is a striking characteristic of both the liver and kidney. These vital organs, which together account for over half of the cardiac output, are so essential to life that they have evolved remarkable regeneration processes surpassed only by muscle and skin. This new book describes in explicit detail the complex morphologic and biochemical changes which occur in both the liver and kidney in response to loss of tissue mass. The direct and concise presentation provides the clinician with a clear understanding of the mechanisms, similarities, and differences in the response of these two organs. Thus the rapid hyperplasia which occurs within the liver is sharply contrasted to the slower hypertrophy of existing nephrons, accounting for most of the increase in renal mass. At the same time, descriptions of complicated processes such as DNA synthesis and replication, or changes in the cellular ultrastructure provide the
