To the Editor.—
Multiple glomus tumors are still a rare manifestation of this type of vascular hamartomas.1 Unlike the single classic digital type, the multiple type is usually painless, and the tumors can spread over the face and trunk. A form of these multiple lesions is the so-called glomangioma.2 In this form, the polygonal cells around the endothelial cells are usually small, with clear eosinophilic-staining cytoplasm and homogenous round nuclei. These glomus structures, then, are smaller and are formed in thin sheets around the endothelial cells, unlike the larger type of glomus cell and larger solid masses in the single glomus tumor.The biopsy specimen differentiates this from the blue-rubber nevus vascular tumor, which has been treated also with the CO2 laser.3,4 The treatment of the single glomus tumor is usually excision since, in our experience with such tumors, recurrences are more apt to occur
