Gingival fibromatosis is a heterogeneous group of enlargement characterized by progressive increase in gingival connective tissue elements. Most of the cases are iatrogenic, and some are inherited or idiopathic. Here, we present an unusual clinical presentation of nonsyndromic idiopathic gingival fibromatosis with unknown etiology in a 20-year-old female. The diagnosis was made based on history, clinical examination, radiographic findings, and histopathology.

| Introduction|| |
Gingival fibromatosis represents the fibrous hyperplasia of the gingival tissue.
Many forms of gingival fibromatosis are of unknown etiology and termed as idiopathic gingival fibromatosis (IGF).
IGF is a slowly progressive benign lesion caused by collagenous overgrowth of the gingival connective tissue that affects the interdental papilla, marginal gingiva, and attached gingiva. 
Gingival fibromatosis may potentially cover the considerable portion of crown, causing esthetic and functional problems such as difficulty in eating, speaking, mastication, and inadequate lip closure. The gingival tissues are usually present with pink, nonhemorrhagic, firm with fibrotic consistency. ,
Histopathologically, idiopathic gingival enlargement is characterized by the bulbous increased connective tissue is relatively avascular and has densely arranged collagen fiber bundles, numerous fibroblasts, and mild chronic inflammatory cells. 
Here, we report an unusual case of a nonsyndromic, idiopathic gingival enlargement with unknown etiology.
| Case Report|| |
In the present case, a 20-year-old female reported to the Department of Periodontology at Career Postgraduate Institute of Dental Sciences and Hospital, Lucknow, Uttar Pradesh, with a complaint of swollen gums since last 2 years with poor esthetics and functional problems. There was no history of drug treatment.
Her current health condition and mental status were normal. She revealed that none of her family members were affected with any form of gingival enlargement. Intraoral examination revealed massive, generalized diffuse type of gingival enlargement involving both the arches [Figure 1]. Gingiva was pale pink, non-hemorrhagic, fibrotic with firm consistency. Severity of gingival enlargement was not related with the amount of local factors present, and the presence of local factors might be secondary to gingival enlargement because a massive gingival enlargement interferes to maintain proper oral hygiene by the patient. Intraoral panoramic radiograph revealed no alveolar bone loss [Figure 2]. Considering the severity of the enlargement, a quadrant-by-quadrant external bevel gingivectomy was chosen as the preferred surgical technique after scaling and root planing [Figure 3]. Histopathological investigations of the excised tissue [Figure 4] revealed densely arranged collagen fiber bundles, numerous fibroblasts, and chronic inflammatory cells [Figure 5]. Postoperative healing was satisfactory, and desired crown lengthening was achieved. Esthetics and functional problems were significantly improved in terms of gingival appearance after surgical excision of enlarged gingival tissue. There was no recurrence of the disease even after 2- years follow-up [Figure 6] and [Figure 7].
| Discussion|| |
Gingival fibromatosis may appear as an isolated entity or may sometimes associated with other condition such as drugs, syndromes such as Cowden syndrome, Ramon syndrome, Zimmermann-Laband syndrome, Jones syndrome, and Cross syndrome.  However, several authors' use various terms such as gingivostomatitis, elephantiasis gingivae, hereditary gingival hyperplasia, idiopathic fibromatosis, and hypertrophied gingivae, to describe these lesions. ,
The similar clinical appearance of these lesions to hereditary gingival fibromatosis (HGF) might have led to misdiagnosis. These complications in the clinical diagnosis necessitate a detailed examination of the patients. Past medical history can eliminate the probability of drug-induced gingival enlargements. Histopathological investigation may also help in clarifying the existence of neoplastic leukocytes, which are abundant in leukemic gingival hyperplasia. As to our consideration, the most difficult part in the differential diagnosis could be the presence of HGF, which is frequently associated with hypertrichosis, mental retardation, epilepsy, and familial disturbances.  Syndromic gingival fibromatosis has been associated with ancillary features such as hypertrichosis, epilepsy, mental retardation, progressive sensorineural hearing loss, and abnormalities of the extremities, particularly of the fingers and toes. ,
However, clinically and histopathologically, it is difficult to differentiate the enlargement may be due to drugs, hereditary, or it is idiopathic.  In this case report, we established the diagnosis of IGF through patient history, clinical, radiographical, and histopathological findings.
Although a progressive fibrous enlargement of the gingiva is a feature of Idiopathic fibrous hyperplasia of the gingiva. 
Royer et al.  revise the hypothesis of gingival fibromatosis which include:
Histologic features of gingival fibromatosis have been based on the connective tissue alterations, which showed an increased amount of collagen fiber bundles associated with fibroblasts and the epithelium showing elongated rete pegs.  This histologic feature was found in the present case.
- Direct stimulation of fibroblast, production of an altered less easily degraded collagen, and increased activity of enzyme prolyl hydroxylase which is important for polymerization of collagen ,
- Direct fibroblast stimulation hypothesis is in question. Recent studies suggested that fibroblasts from fibrotic tissues remain activated, even in the absence of continuous stimulation. 
There are various treatment modalities available for removal of gingival enlargement including surgery, electrocautery although the most effective method for removing large quantities of gingival tissue is external bevel gingivectomy, especially when there is the presence of pseudopocket and no attachment loss. 
There is no any clear-cut evidence about recurrence, so the postoperative long-term benefit of periodontal surgery cannot be predicted. In this case report, there was no recurrence of the lesion even after 2 years of follow-up was observed.
