title: Morphometry in surgical pathology.
abstract: The potential role of morphometry in surgical pathology is discussed. Specific areas in which morphometry could be helpful are in (1) identifying malignant cells in lesions that are largely composed of benign-appearing cells (e.g., follicular thyroid neoplasms), (2) defining reference points in apparent continua (e.g., in the progression from normal colon to adenoma to adenocarcinoma), (3) distinguishing between benign and malignant lesions with similar appearances (e.g., fibromatosis and fibrosarcoma of the soft tissue) and (4) distinguishing between similar-appearing types of malignant neoplasms (e.g., between small-cell carcinoma of the lung and small-cell lymphoma). Morphometric techniques are already being used in DNA ploidy determinations, which frequently bear prognostic information. The measurement of other nuclear and cellular parameters has been used for both diagnostic and prognostic ends; one example is the relation of nuclear roundness to metastatic potential in prostatic carcinomas. Morphometry is now being increasingly applied to histologic sections, as in the prognostic study of lesion thickness in malignant melanoma and the diagnostic study of glandular architecture in colonic adenoma. The use of morphometry can enhance the observation and interpretation of morphologic features, which, combined with the clinical data and the experience of the pathologist, can lead to greater accuracy and precision in surgical pathology diagnoses.
