The missed malignant case.
There is no doubt that the vast majority of delayed diagnoses in malignant disease are due to fear and ignorance on the part of the patient. This delay is appalling, as the figures from the Registrar General 19-7 show. The mean delay in cancer of the breast is 6.2 months but 17.3 per cent wait over two years. In the cervix uteri it is 5.7 months and 8.4 per cent wait over two years, and for rec...

The recognition of iris melanoma is important because a number of benign lesions clinically resemble these tumors. In this article, the epidemiological, clinical and histopathological features, treatment modalities, and prognosis of 41 iris melanoma patients, seen between 1964 and 1996 were evaluated. Of the patients, 20 were men and 21 women. Their mean age was 44.6 years. After determining th...
متن کاملAngioarchitecture of primary oral malignant melanomas.
Angiogenesis is an essential process in the progression of malignant tumors. However, little is known of the angioarchitecture in primary oral malignant melanoma. We sought to determine this by the use of periodic acid-Schiff (PAS) stain, endothelial markers (CD34, CD105) and laminin, and by transmission electron microscopy in two cases. The results demonstrated that endothelium-lined vessels d...
متن کاملUltrastructure of malignant melanomas of the choroid.
Eleven vialignant melanomas of the uveal tract have been studied by light and electron microscopy. Two types of cells were found in the epithelioid tumors: one, a darker type, contained large amounts of free RNP particles in single granules or in clusters, many smooth membranes and vesicles, and numerous mitochondria; the lighter type had similar cytoplasmic components, but in a lesser amount, ...
متن کاملImmunological studies on malignant melanomas of man.
In this paper, we have reviewed current problems in tumor immunology with regard to melanoma and report our studies of a small series of patients with melanoma and other malignancies. A humoral response to malignant melanoma has been well established by the immunofluorescence test (1-5). Cross-reacting cytoplasmic antigens were detected as were cross-reacting and individually specific membrane ...
