Extradigital Symplastic Glomus Tumor and Review of the Literature

Eva B Niklinska et al. Am J Dermatopathol. .

Abstract

Symplastic glomus tumors are a rare subtype of glomus tumor defined by nuclear atypia without additional markers of malignancy such as large size, deep location, or atypical/prevalent mitotic figures. Glomus tumors, including the symplastic subtype, most commonly present in the subungual area with rarer extradigital presentation. To our knowledge, there have been less than 25 cases of symplastic glomus tumors described in the literature. Herein, we present a case of extradigital symplastic glomus tumor with review of the literature.
