“…As for the latter, both tumors stain for S100 protein and epithelial membrane antigen but only chordoma expresses the t-box transcription factor brachyury. 3 Immunohistochemistry for a variety of cytokeratins (CKs) (8/18, 1/10, 7, and 20), epithelial membrane antigen (EMA), S-100 protein, vimentin CD-34, type IV collagen, smooth muscle actin, smooth muscle myosin heavy chain, calponin, and glial fibrillary acid protein was performed in a study of six cases. All parachordomas strongly expressed CK 8/18, but not the other cytokeratins.…”

Parachordoma is an uncommon tumor of soft tissue and the orign is not clear. This soft tissue tumor resembles chordomas as well as extraskeletal myxoid chondrosarcomas and has only recently been fully characterized. Although it is considered a benign lesion, its behavior tends to be locally aggressive, with reports of a recurrence rate of up to 20% and of several cases of metastasis. In this article, we report a case of parachordoma in the neck with recurrence that we met in clinical works.

Parachordoma is one of the rarest tumors identified, with around fifty cases reported to date. It is reported to have a benign behavior, yet metastatic and fatal cases have been reported. A 63-year-old female patient presented with a subcutaneous mass in the right deltoideal region. After two excisional biopsies with tumor-free surgical margins and 33 cycles of radiotherapy, the case presented with a second recurrence. Due to malignant features in the second histopathological examination, she was treated with excision of the deltoid muscle, and the defect was reconstructed with latissimus dorsi myocutaneous flap. There is no standardized treatment protocol for parachordoma. Yet, increased mitotic activity and atypical mitotic figures arise suspicion for recurrent and malignant behavior. In the presence of these features in histopathological examination, tumor should be considered as low-grade sarcoma and be treated accordingly.
