It is a rare variant of SCC characterized by malignant spindle-shaped cells resembling sarcomas. Spindle cell lesions of the head and neck are diverse with great clinical and biological variety. They tend to show rapid progression with a high recurrence rate and the ability to metastasize, all of which contribute to their poor prognosis.<\/jats:p>","DOI":"10.4103\/aam.aam_201_25","type":"journal-article","created":{"date-parts":[[2025,11,5]],"date-time":"2025-11-05T11:00:09Z","timestamp":1762340409000},"page":"986-989","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Spindle Cell Carcinoma: A Rare and Aggressive Variant of Squamous Cell Carcinoma of the Upper Lip"],"prefix":"10.4103","volume":"25","author":[{"given":"Prabhat Bhaskarrao","family":"Nichkaode","sequence":"first","affiliation":[{"name":"Department of Surgery, Dr. D.
