Senile Venous Lakes

To the Editor.—  I read with great interest the report by Bondi and Clark in the March Archives (1980;116:299-300) on the clinical differentiation of adult-onset cavernous angioma from nodular malignant melanoma. They described 14 patients who had 16 asymptomatic pigmented nodules suspected of being nodular melanomas. The authors claim that a 30-s pressure on the lesion is a reliable test for differentiating nodular melanoma from senile angioma, since there is a good histopathologic correlation with the clinical test.In 1961, Woringer and I1 described eight patients who had lesions similar to those reported by Bondi and Clark. We have already pointed out the resemblance of these lesions to nodular melanoma. The histologic picture is characteristic, showing a large jagged venous lake, crossed by thin walls of fibrous tissue supporting normal capillaries. As noted by Bondi and Clark, the venous lakes collapse completely under pressure and refill when the pressure
