A quantitative histomorphologic analysis of lymph node granulomas in Sarcoidosis in relation to radiological stage I and II.

In a detailed study of granulomas in lymph nodes of 19 patients with Sarcoidosis we assessed and correlated a number of features, with size, development and radiographic staging of the disease. Except with the epithelioid cells the number of constituent cells (lymphocytes, giant cells and polymorphs), size, confluency and degree of necrosis of the granulomas were found to be very variable within a single gland. This indicates that the granulomas are in different stages of activity at a given time. All the features studied showed little or no correlation with the radiographic staging, which suggests that the latter is not a good index of the extent of the disease.
