Based on morphology, it can be classified as classical biphasic variant, monophasic spindle cell variant, monophasic epithelial variant and poorly differentiated variant. The authors with an index case of 74 year old lady with monophasic spindle cell synovial sarcoma of oral tongue which is one of the rarest variants (our case is the 15th case reported of synovial sarcoma of the tongue and only the 3rd case in the world which had a monophasic histopathologic pattern) studied the morphology and described the disease entity in detail. She was treated with wide local excision of sarcoma followed by adjuvant radiotherapy.
