Metastases to palm, sole, nailbed, nose, face and scalp from unsuspected carcinoma of the lung

A case is recorded in which bizarre metastases to the palm, sole, nailbed, nose, cheek and scalp were the first presenting signs of an unsuspected pulmonary carcinoma. Their unique appearance suggests that a precise phenomenon may be at work, the pathogenesis of which is still unknown. It has not been determined whether they are characteristic of a particular type of primary neoplasm. In the presence of unexplained skin malignancies, the possibility that they may be metastatic should be considered and a search for internal malignancy should be instituted.
