pain. The swelling started growing rapidly to attain the current size of about 2X3 centimeters, with mild dull continuous aching pain in check for the past 20 days (Figure 1). The patient had no significant previous medical, dental history, or any reported allergies to known drugs.

None of the family members were diagnosed with malignancy nor did the patient’s mother was subjected to any kind of radiation during her pregnancy. Thorough physical examination revealed no significant abnormalities.

Loco-regionally, an oval-shaped swelling was present at the left buccal region measuring 2X3cms covered with normal-appearing skin extending superior inferiorly from malar prominence to corner of the mouth, anterior-posteriorly from nasolabial fold to 1 cm ahead of the preauricular region.

Mild tenderness was elicited on palpation with firm swelling detached from the overlying skin, however swelling appeared non-mobile, non-reducing, non-compressible, nodular, and single. The auscultatory finding was observantly negative.

The patient had adequate mouth opening, on availing which, an oval swelling present was at the pyriform region on the left side with well-defined borders, obliterating the vestibular depth and covered with inflamed gingiva.

Swelling extended superior-inferiorly from the depth of the buccal vestibule to the cervical margin of the teeth and antrio-posteriorly from ipsilateral deciduous maxillary canine to the permanent first molar.

The swelling was tender, firm, fixed to the underlying bone and overlying gingivomucosal tissue. Computed tomography revealed an expansile osteolytic lesion at the posteroinferior maxilla (Figure 2). Fine needle aspiration cytology did not yield fluid or cellular content.

With a provisional diagnosis of Spindel cell tumor and differential diagnosis of Giant cell granuloma, the patient was prepared for an excisional biopsy. Upon performing wide local excision of the lesion along with antral lining and floor of the orbit, the defect was reconstructed with Bachet’s flap.

Histopathological evaluation of the specimen confirmed Fibrosarcoma (Figure 3).

According to SEERS a program of the National Cancer Institute, fibrosarcomas occurring in adults, accounts for 3.6% of all adult sarcomas, and depending upon the source, the patient’s sex may or may not play a role [7].

Sarcomas arising from fibroblasts are predominantly found in the areas adjoin or within the medullary bone. Documented anamnestic of Fibrosarcomas, reveals peak incidence occurs at 3^rd decade of life, whereas, in our case, this has been diagnosed in 6 years old patient.

Wadhawan and colleagues proposed that, for the confirmation of fibrosarcoma, vimentin staining should be done and the Herringbone pattern is confirmatory, in the current case Herringbone pattern was observed on Histopathological evaluation and vimentin staining was positive as an Immunohistochemical marker [8,9].

A study conducted by Daniela Augsburger and colleagues in 2017 reports that the mainstay of treatment is generous excision with adequately wide margins, therefore even being a young patient she was undertaken for a wide local excision [4].

The role of chemotherapy is debatable, yet to avoid recurrence, is advocated to be supplemented with radical surgery, considering the age and incidence of recurrence, the patient was, therefore subjected to post-operative chemotherapy [10].

However current data is insufficient to establish a definite treatment plan at such young age, therefore the importance of this case report should not be challenged as it adds to the information regarding the age-related treatment of such fulminant, locally aggressive, and recurring malignancy.
