METASTATIC BASAL CELL EPITHELIOMA

Abstract

A CAREFUL search of the literature reveals few cases of metastatic basal cell epithelioma. Most of the cases reported as such later proved to be of the basal-squamous type. There are, however, several cases which are generally accepted as metastatic basal cell epitheliomas and a number of others which are thought to be possible cases of metastatic basal cell epithelioma. In 1931, Niles¹reported a case of metastatic basal cell epithelioma which later proved to be of the basal-squamous type.²A review of the literature in his report included 5 cases of metastatic basal cell epithelioma, 1 each reported by Beadles, Janeway and Körbl (case 61) and 2 reported by Finnerud,³and 4 cases of possible, but in his opinion not proved, metastatic basal cell epithelioma reported by D. W. Montgomery, Dubreuilh and Auché, Fordyce and Marassovich.⁴ In 1935, H. Montgomery⁵pointed out that the
