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.

Synovial sarcomas is a mesenchymal tumor that usually occurs in the extremities. Fewer than 100 cases of synovial sarcoma have been reported in the head and neck lesion. We experienced 2 cases of synovial sarcoma of neck, and so reported with a review of literature.

A case of malignant synovioma of the right knee joint is presented. Microscopically it showed sarcomatous growth of spindle cells and irregular slit spaces which were lined by tumor cells. A–K amputation has carried out on 10th hospital day and discharged on 30th hospital day without any complications.

Synovial sarcoma is comparatively uncommon and highly malignant tumor, which usually arises in proximity to a joint and may affect the adjacent bones. Occurence in finger and severe bony involvement are rare. We present a case of synovial sarcoma of the thumb, because the tumor arose in an unusual site and was characterized by severe bony destruction.

Malignant tumors arising from tendon and aponeurosis are very rare. Among those reported most have been interpreted as synovial sarcoma or fibrosarcoma until Enzinger in 1965 described a new type which he called “Clear Cell Sarcoma of Tendon and Aponeurosis”. The tumor has a uniform and distinctive clinical and morphological pattern which distinguishes it from other groups of tenosynovial tumors. The problem of its histogenesis remains, especially its relation to synovial sarcoma. In this paper, we reported one case which is believed to be “Clear Sarcoma in the thigh”.

We recently experienced a case of synovial sarcoma in the posterior neck, which involved adjacent bony structures. Synovial sarcoma is rare, malignant soft tissue tumor that occur predominantly in the lower extremities. Wide surgical excision with involved tissue is the treatment of first choice, because most synovial sarcomas reveal aggressive features. We removed the tumor with involved bony structures and patient was given postoperative radiation therapy. Despite these treatment options, the patient died 1 year after surgery. We report this case with a review of the literature.
