Numerous, painless, dark-red small papules approximately 300 in number developed in a localized area of the left abdomen of a 16-year-old Japanese male in a course of 4 years. Histologically, there were dilated vascular spaces surrounded by one to three layers of cuboidal cells in the upper and mid dermis. Electron microscopic examination revealed the characteristic muscle cell structure of the tumour cells. To our knowledge there is no other report in the literature of such a case of localized multiple glomus tumors with numerous small papules and we think that this case represents a unique type in the multiple glomus tumor.
