Ectopic Hamartomatous thymoma(EHT) is a rare benign tumor that occurs mainly in the supraclavicular or suprasternal area. Since this entity was first reported by Smith et al. in 1982, less than 50 cases have been reported in the literature. Recognition of EHT is important and needs to be differentiated from high-grade sarcomas such as synovial sarcoma or malignant peripheral nerve sheath tumor because EHT follows a benign clinical course. We experienced a case of ectopic hamartomatous thymoma in the suprasternal area in a 53-year-old man. Here, we present the case with a review of the related literatures.

Ectopic hamartomatous thymoma is a rare benign tumor of the lower neck occurring in the male adult predominantly. The origin of this tumor has been debated, but it is now believed to arise from remnants of the cervical sinus of His from early development. They are composed of epithelial, adipocytic, and spindle cells in variable amounts. Recognition of ectopic harmatomatous thymoma is important and needs to be differentiated from high-grade sarcomas such as synovial sarcoma or glandular malignant peripheral nerve sheath tumor. We here report on a case of ectopic hamartomatous thymoma arising in the left lateral neck of 33-year-old male patient.
