Benign tumors seen in the oral cavity include fibroma, pyogenic granuloma, papilloma, pleomorphic adenoma, etc. Some tumors which are more commonly seen in other parts of the body canrarely present in the oral cavity and one such tumor is fibrous histiocytoma (FH). FH, not so common tumor of the oral cavity, is a fibrohistiocytic tumor (Recognized by WHO), which is composed of cell population of fibroblasts and histiocytes[2,3]. They can be cutaneous, non-cutaneous or fibrous histiocytic tumors of bone. The most damaging are the cutaneous type which originate in the sun-exposed skin. The non-cutaneous typeare more common in the lower extremities (50%) and also in the retroperitoneum (20%)[4,5]. The presentation of this tumor in the oral cavity has been reported in relation to buccal mucosa, vestibule, tongue, and floor of the mouth. Rare occurrences are also seen in the nasal cavity and paranasal sinuses, larynx, trachea, temporomandibular joint and submandibular gland[6]. They usually present as a solitary, painless growth which enlarges slowly over a period of several months[6,7]. These two case reports describe the atypical presentation of this tumor in less commonly affected areas i.e. in gingiva, and in particular, its association with the edentulous space. CASE REPORT 1: A 21-year old male patient, reported to the department of Periodontics with a chief complaint of bleeding gums from the lower left region of the mouth for the last 1 month.

INTRODUCTION A neoplasm is a tumor, which literally
means 'new growth'[1].'Tumour' is the most common term
that is heard in medical field, which not only terrifies the
patient, but also sets off an alarm in the mind of the clinician.
Based on their clinical behavior, these tumors are divided into
two types: benign, which are considered to be relatively
innocent, denoting the fact that they are amenable to local
surgical excision; and malignant, those which can metastasize
to distant regions.
There are diverse presentations of these benign and malignant
tumors in the entire body, with the oral cavity being no
exception. Benign tumors seen in the oral cavity include
