Multifocal granular cell tumors of the gastrointestinal tract.

Granular cell tumors infrequently appear in the gastrointestinal tract. Lesions have been reported in all segments from the esophagus to the rectum, but no previous reports have identified simultaneous lesions in various segments. We describe a patient with granular cell tumors of the esophagus, stomach, appendix, and cecum. Our case emphasizes the need to evaluate the entire gastrointestinal tract when a single lesion is identified. The radiographic approach and pathological characteristics are discussed. Therapeutic alternatives are presented.

Nuclear DNA polymerases of human carcinomas.

Comparisons have been made of the DNA polymerases of normal human lung and cecum, primary carcinomas of human lung, breast, and cecum, and resting and regeneration rat liver. The picture for the normal human tissues is similar to the one for unstimulated rat liver, that for the human carcinomas resembles regenerating rat liver. The human tissues contain two polymerases with sedimentation coefficients of about 3 and 7 S, the enzymes are restricted to the nucleus, and the specific activities of the 7 S polymerase, but not of the 3 S enzyme, are elevated in the cancers. Just as with the regenerating rat liver polymerases, the 3 S activity of a bronchogenic carcinoma is unaffected by cytosine arabinoside 5'-triphosphate and only little reduced by novobiocin, whereas DNA synthesis by the 7 S enzyme is abolished by both compounds. A variety of other inhibitory agents have similar effects on the 7 S polymerases of the human carcinomas and regenerating rat liver.

[Adenocarcinoma of the appendix. A propos of a case complicated by double local and parietal recurrence].

Adenocarcinoma of the appendix is rarely encountered and is usually discovered fortuitously at pathology examination of the surgical specimen. Six years after surgery for degenerative villous tumor of the appendix, local and parietal recurrence led to surgery in our patient. We present here the indications for complementary hemicolectomy and management of parietal scars resulting from the initial appendectomy.
