The ultrastructure, differential diagnosis, and biologic behavior of the peripheral pulmonary spindled carcinoid tumor are reviewed. Electron microscopy is useful in distinguishing the spindled carcinoid from a variety of neoplasms with similar histologic features. The spindled morphology is a rare expression of the carcinoid tumor that is almost exclusively confined to the lung periphery. It appears that the spindled carcinoid without atypical features is fully capable of regional lymph node metastases in approximately 20 per cent of the cases.

The clinical and histologic material of 140 patients with gastric carcinoma resected more than 5 years previously was examined and 10 tumors with a previous diagnosis of adenocarcinoma showed atypical carcinoid differentiation. The clinical extent of tumors in this carcinoid group was similar to that of the ordinary gastric adenocarcinoma. The 5-year survival was 15% in patients with adenocarcinoma and 70% in those with carcinoid (P less than 0.01 by chi 2 test). These findings indicate the need to distinguish atypical carcinoids from ordinary gastric adenocarcinoma. The most commonly encountered histologic feature suggesting carcinoid, and leading to confirmatory histochemical studies, was found to be regular interlacing trabeculae of tumor and fibrovascular stroma.

The case of a 33-year-old woman with primary carcinoid of the uterine cervix is reported. Primary carcinoid tumor is well known to occur in organs such as the gastrointestinal tract, lung and gonads. However, its occurrence in the uterine cervix is rare. To our knowledge, primary carcinoid of the uterine cervix has not been reported from the United States, although it has been well documented by non-American authors. Light microscopically, the tumor was characterized by formation of solid nests, trabeculae and glands. The cells therein showed argyrophil granules but were negative for argentaffin reaction. Electron microscopy revealed the presence of numerous neurosecretory granules and microfilaments. On the basis of light microscopic ultrastructural and cytochemical properties, the tumor is believed to arise from the normal argyrophil cell of the cervix and is regarded as an endocrine tumor, a member of the group of neoplasms called apudomas.

I report a case of peripheral bronchial carcinoid tumor composed of bundles of large spindle cells, very much resembling cells of smooth muscle or neural tumors. Despite the unusual appearance, argyrophil staining and electron microscopic examination demonstrated small secretory granules of the type found in other peripheral carcinoid tumors. The histologic heterogeneity of peripheral bronchial carcinoid tumors is emphasized.

Primary adenocarcinoma of the appendix is a rare tumor. Fewer than 200 cases are on record. Correct preoperative diagnosis is virtually nonexistent. Two patients with adenocarcinoma of the appendix are described. Although appendectomy appears to be adequate treatment for carcinoid, right hemicolectomy is, in our opinion, the treatment of choice for mucinous cystadenocarcinoma, while it is mandatory in cases of adenocarcinoma of the colonic type.

Malignant tumors of the small bowel are rare but carry a grave prognosis. Thirty-seven cases from the Tumor Registries of Brooke Army Medical Center. Fort Sam Houston, Texas, and Fitzsimons Army Medical Center, Denver, Colorado, were retrospectively studied. Twenty-nine males and eight females ranging from five to 86 years were included in the combined series. Thirteen carcinoid tumors, eight adenocarcinomas, seven lymphosarcomas, five leiomyosarcomas, two reticulum cell sarcomas, one liposarcoma, and one mesenchymal cell sarcoma were found. Symptoms included intermittent crampy abdominal pain, intestinal obstruction, intestinal bleeding with anemia, and weight loss. The diagnosis was made on the basis of the clinical picture in addition to physical findings and pertinent x-ray contrast studies. The overall survival rate was 25%. The treatment of choice is surgical extirpation of the tumor whenever possible followed by appropriate adjunctive modalities.

A strumal carcinoid arose in a benign cystic teratoma of the ovary. Ultrastructural studies demonstrated that both the solid acinotubular areas as well as the "follicular" components were comprised of light and dark cells that contained numerous secretory granules. These findings indicate that this neoplasm is a pure carcinoid tumor with a follicular pattern. The present study raises the question of whether all strumal carcinoids are indeed pure carcinoid neoplasms.

A case of pure, primary testicular carcinoid tumor in a forty-four-year-old male is reported. The patient presented with painless testicular enlargement, and testicular tumor was diagnosed. Orchiectomy was performed, and histology revealed a primary argentaffinoma. The patient is well and symptom free two years after diagnosis.
