Giant-cell tumors of soft tissue in the head and neck: A review article

Giant-cell tumor of soft tissue (GCT-ST) is a rare neoplasm that was first described in 1972. Due to its histological and immune-histochemical similarities with GCT of bones, GCT-ST is thought to be its counterpart. This review article aims to recognize the characteristics of this rare tumor along with a favorable way to diagnose and treat. We reviewed 12 cases of GCT-ST in the head and neck. This tumor involves both sexes at any age. Histopathology in many cases revealed the presence of mononuclear cells and spindle cells. Immunohistochemistry was positive in many cases for CD68. Complete excision was the most accepted management technique; however, few cases reported recurrence and metastasis. Post-operative radiology is suggested to prevent local recurrence and in case of incomplete excision of the tumor.
