Quantification of Grimelius reaction in neuroendocrine tumors of the lung.

The authors have studied the percent area occupied by the Grimelius-positive cells in lung neuroendocrine tumors. The highest values were noted in typical carcinoid tumors: they decreased progressively in atypical carcinoids, small "oat cell" carcinoma and large cell carcinoma. There was, however, a large dispersion of values, especially in the groups of typical and atypical carcinoid tumors. The possible significance of these data in the diagnosis, evaluation of therapeutical results and prognosis is discussed.

Study on the nucleolar organiser regions in soft tissue liposarcoma.

The authors studied 24 cases of liposarcoma of soft tissue included in two categories: myxoid liposarcoma and pleomorphic liposarcoma. The 24 tumors were stained by Ploton's method for revealing the nucleolar organiser regions (AgNORs). AgNORs were counted in the nuclei of 100 cells/case. AgNORs in the cells of some cases showed hyperchromasia and an increased size. The results suggest a role of AgNORs as a possible prognostic discriminator of different histological types.

Morphometric investigations on bone giant cell tumors.

The authors have studied 12 cases of bone giant cell tumors and have shown that the increase in aggressiveness is accompanied by higher values of mitotic activity and nuclear features (area, perimeter, long and short axes), which might be useful for grading the bone giant cell tumors.
