Introduction: Gingiva is a very common site of oral tumors, which may be benign or malignant with or without metastasis. Common to rare malignant neoplasms of gingiva have been reported in the literature. Spindle cell carcinoma is a rare and peculiar biphasic malignant neoplasm that occurs mainly in the upper aero digestive tract. It consists of sarcomatoid proliferation of pleomorphic spindle cells in squamous cell carcinoma. It is considered potentially aggressive in its biological nature with a high incidence of metastases.
Case presentation: A 51-year-old male patient reported with a chief complaint of swelling in the Lower left tooth region. The patient gave history of painless slow growing swelling associated with tooth number 33, 34 since 8 months with no history of treatment in the past. The excised tissue was fixed in 10% formalin solution and submitted for histopathological examination.
Results: The postoperative healing was uneventful at 2 week time interval at which time the histopathological report was also received and the lesion to our surprise turned out to be malignant i.e. sarcomatoid carcinoma.
Conclusion: The seemingly non threatening gingival enlargement may sometimes be a deceptive and rare entity challenging to the health science fraternity because of its unusual appearance and behaviour. Hence, thorough clinical and histopathogical investigation is a must.
