The difficulty of differentiating an epithelial skin tumour with partial adenoid histological features from a metastasis of an internal adenocarcinoma is exemplified by a case report of an 83-year-old woman. Histological, histochemical and ultrastructural results led us to suppose that two different carcinomas with metastases were present: an adenocarcinoma of the colon and a 'unicellular muciparous squamous cell carcinoma of the skin'. The nosological proximity of the primary skin tumour to mucoepidermoid tumours and to sweat gland carcinoma of the ductular epithelium will be considered in more detail.

Metastatic involvement of the spleen is uncommon. Lymphoma is the most common cause of primary and secondary malignant lesions of the spleen, whereas splenic metastases from carcinoma are rare and usually occur in a setting of concomitant carcinomatosis with melanoma, breast, ovary and lung accounting for the principal primary tumors. We report a case of an isolated, focal splenic defect demonstrated by Tc-99m-sulfur colloid scintigraphy which was the only visual evidence of metastatic adenocarcinoma of the colon. To our knowledge this unusual cause of a focal splenic defect on liver-spleen scintigraphy has not been previously described.

Cholesterol feeding of rats with colon cancer induced by dimethylhydrazine results in reduced survival and an increased incidence of metastatic colon cancer. As cholesterol may be implicated in the induction or maintenance of the metastatic process, an experiment was designed to determine whether rats with colon cancer would benefit from the removal of cholesterol from the diet. Female Wistar rats were treated with a colon cancer-inducing regimen of dimethylhydrazine (40 mg/kg/week for 10 weeks) while being fed on a standard cholesterol-containing rat pellet diet. After two rats had died spontaneously of histologically proven adenocarcinoma of the colon at 24 weeks, the remaining rats were randomly allocated in groups of 15 to one of three dietary regimens. Group S continued to receive standard pellet diet, group V were fed on Vivonex alone and group VC were fed Vivonex plus cholesterol (10 mg/100 ml Vivonex). Each group was assessed for survival and incidence of histologically proven metastatic disease. There were no differences in either survival or incidence of metastases when groups S and VC were compared. In the cholesterol deprived group V, however, there was a significant increase in survival compared with groups S and VC (p less than 0.02) and this was due to a significant reduction in the incidence of metastases (p less than 0.05). Cholesterol deprivation therefore benefits rats with established colon cancer induced by dimethylhydrazine by improving survival and reducing the incidence of metastases.

The frequency of metastases of solid primary tumors into the respiratory tract is estimated to about 5% by means of bronchoscopic and bronchofibroscopic examinations. The clinical and roentgenological picture of endobronchial metastases in most cases is corresponding to that of a primary bronchial cancer. For differential diagnostics endobronchial metastases have to be delimited from primary bronchial carcinoma, from the multilocular forms of the primary bronchial carcinoma, from benign tumors and pseudotumors of the respiratory tract. The possibility of double tumors (tumorduplicity) must not be forgotten, as well. The endoscopic signs of a benign tumor endobronchially growing are described. However, only the histological or cytologic examination will give certainty. The endoscopic picture of a primary bronchial carcinoma with metastases and other possible multilocular endobronchial alterations are described. In our material the error was most frequent, that the bronchial cancer was confounded with the metastases. During the last 20 years we have observed endobronchial metastases in 22 patients with bronchoscopic methods. In 13 patients an extrapulmonary solid tumor made metastases into the bronchi, breast cancer 4 times, Grawitztumors, adenocarcinoma of the colon, carcinoma of the thymus each two times, cancer of the uterus, of the urinary bladder and the thyroid each one time. In 9 patients autochthonous metastases of a primary bronchial carcinoma were found.

Metastases to the breast from extramammary carcinomas are rare. Only about 200 cases are reported in the literature. Fifteen additional cases are presented here and the literature is reviewed. Two of the patients has primary thyroid carcinoma, two adenocarcinoma of the colon, three bronchogenic carcinoma, four malignant melanoma, one a squamous cell carcinoma of the oesophagus, one an adenocarcinoma of the stomach, one a renal cell carcinoma and one a carcinoid of the terminal ileum. In three cases the breast lesion was the first manifestation of an extramammary cancer. Six of the patients died of disseminated cancer shortly after the breast metastasis was diagnosed. Although breast metastasis may be suspected clinically, exact histological diagnosis is important in order to avoid unnecessary surgical treatment and to guide further therapy.

We reviewed ultrasound examinations of the liver performed at Yale--New Haven Hospital on patients with biopsy-proven tumors since January 1, 1977, to correlate the ultrasonic appearances with histology. Liver metastases appeared as sonolucent lesions in 37.5% of patients, as mixed sonolucent/echogenic lesions in 37.5%, and as solely echogenic in only 25%. We found a limited correlation between the echogenic pattern of the ultrasound scans and histology. The majority of echogenic metastases were from colonic primaries (54%) or hepatomas (25%). Metastases from lymphomas were extremely sonolucent and sarcomas frequently demonstrated central necrosis. Calcified metastases from mucin-secreting adenocarcinoma of the colon appeared as dense lesions with distal shadowing.

This paper describes the imaging features of ovarian metastases from adenocarcinoma of the colon in adolescent females. We reviewed retrospectively abdominal and pelvic computed tomographic and pelvic ultrasound examinations, histologic slices, and clinical charts of six adolescent females with ovarian metastases secondary to adenocarcinoma of the colon. One patient had ovarian metastasis at presentation and was presumed to have a primary ovarian tumor. The ovarian metastases were either solid (n = 3), complex with both solid and cystic components (n = 2), or multilocular cysts (n = 1). The ovarian lesions were large, ranging from 6 cm to 18 cm in diameter. Colorectal carcinoma in adolescent females is frequently associated with ovarian metastases. One imaging characteristic differs in adult and adolescent ovarian metastases, although they do have features in common: in adolescents, a smaller proportion of colorectal ovarian metastases are multicystic (17%) compared with the adult series (45%). These lesions are frequently large and may be complex, multicystic, or solid. Although it is a rare disease, the differential diagnosis of adnexal masses in adolescent females should include ovarian metastases from adenocarcinoma of the colon.

Two female patients with an adenocarcinoma of the colon (Duke stages B and C) underwent colectomy followed by adjuvant chemotherapy combining 5 fluorouracil (5 FU) and levamisole. Secondary neurological manifestations occurred in both patients including vertigo, nausea and vomiting, dizziness with loss of balance, slow ideation, impaired memory, headache and, on one case, central origin facial paralysis. Symptoms appeared between the 11th and 34th week of treatment. The patients had received 9 to 30 g 5 FU and 2.7 to 7.6 g levamisole. CT scan and/or MRI first suggested cerebral metastases then demyelinisation. The clinical signs disappeared spontaneously in less than one month. The brain images were unchanged. The 5 FU/levamisole combination was undoubtedly responsible for the neurological manifestations. Levamisole may have potentialized the effect of 5 FU leading to demyelinisation. Whether chemotherapy should be stopped or not is debated.

The authors report about 4 cases of splenic metastases in patients with the following neoplasms: urothelial carcinoma of the left kidney, adenocarcinoma of the uterine body, adenocarcinoma of the left flexure of the colon, adenocarcinoma of the sigmoid loop. On large autopsy series, metastases to the spleen are not rare (7% in average), and rank 10th among the 44 metastatic sites described in the literature. Cancers of the breast, lung, skin (melanoma), ovaries and stomach (cardia) make up more than 60% of the primary tumors. The diagnosis is most often accidental (surveillance of operated patients), rarely clinical (pain, splenomegaly), and it is based on medical imaging (ultrasound, CT). In the absence of hemostatic disorders, percutaneous needle biopsies are possible. Treatment, when at all possible, is surgical (splenectomy) and must comply with carcinological rules.

Flow cytometry was performed upon 312 patients with adenocarcinoma of the colon and rectum, satisfactory results being obtained with 275 (108 diploid, 130 aneuploid and 37 tetraploid). The proportion of nondiploid instances increased from 28 percent if one, to 80 percent when six specimens were assessed per patient. Reproducibility of the technique showed substantial agreement in the assessment of deoxyribonucleic acid ploidy (Kappa value equals 0.74). Increasing values of cells in the diving (G2/M) phase of the cell cycle were associated with little lymphocytic tumor infiltration (p = 0.0002) and extensive tumor fibrosis (p = 0.003). Univariate survival analysis revealed that, although diploid tumors tended to have a better prognosis than nondiploid tumors (p = 0.06), no flow cytometric variable was significantly related to survival. Flow cytometry similarly was not of prognostic value in instances without lymph node metastases or without distant metastases. Multivariate regression analysis of flow cytometric and clinicopathologic variables identified Dukes' stage, patient age and tumor differentiation as the combination of variables most closely related to survival. No flow cytometric variable could significantly improve on the prognostic model containing these three variables. It is concluded that conventional histologic variables remain the best predictors of prognosis in carcinoma of the colon and rectum.
