Glomus tumor of the liver presenting as a cystic lesion

摘要

Glomus tumors are rare mesenchymal neoplasms, originally described in 1924 by Masson,1 which commonly occur in the skin or superficial soft tissues, especially in the distal extremities.2 Cases of glomus tumors occurring in visceral organs have rarely been reported. Moreover, only three cases of glomus tumors in the liver have been reported in the English literature,3"9 and no such cases exist in the Japanese literature. Herein, we report on the fourth case of a glomus tumor in the liver, which was unique in that the tumor comprised a large monolocular lesion.
