Abstract

Ectopic hamartomatous thymoma (EHT) is a rare and distinctive benign tumor that usually occurs in the supraclavicular, suprasternal areas. Histopathologically, it is characterized by a mixture of spindle cells, epithelial cells, and adipose cell elements. The recognition of EHT and differentiation of it from high-grade sarcomas such as synovial sarcoma is important, because EHT follows a benign clinical course and conservative surgical excision is the treatment of choice. We experienced a case of EHT in the supraclavicular area, so we present the case with a review of the related literatures.
