Abstract
The fibrous epulis, a common tumor-like lesion of the gingiva, appears in the interdental papilla as a result of local irritation. Lesions are asymptomatic and have a variable growth rate. A 75-year-old woman was referred for the evaluation of a large painless gingival mass. It had started 10 years back and has been increasing in size the last year. No bone involvement was noted. The tumor was totally removed by excision with surgical scalpel under local anesthesia without teeth extraction. The microscopic findings were suggestive of a fibrous epulis. Differential diagnosis, clinical considerations and factors to prevent recurrence are discussed.

Because of the unusual size and evolution, the differential diagnosis and clinical considerations are discussed.</p></sec><sec><title>CASE REPORT</title><p>A 75-year-old woman was referred to the Laboratory of Oral Pathology (Cordoba, Argentina) for the evaluation of a large painless gingival mass, with approximate 4 cm×6 cm×3 cm swelling arising from the maxillary gingival in relation to the upper central incisors, covered by partially ulcerated mucosa (<xref ref-type="fig" rid="fig1">Figure 1</xref>). It was firm in consistency, irregular surfaced, pedunculated, and did not bleed when touched. No tooth mobility in this region was noted, and regional lymph nodes were normal. Radiographic examination did not demonstrate any bone involvement (<xref ref-type="fig" rid="fig2">Figure 2</xref>). The patient presented considerable deposits of bacterial plaque. The mass had started insidiously 10 years back and has been progressively increasing in size the last year. Except for a controlled hypertension (potassium Losartan 50 mg daily), her medical history revealed no other pathological condition. This mass led to some difficulty in speaking, eating and closing her mouth. Operative findings revealed that the lesion was indurated.</p><p>The tumor was totally removed in one piece by excision of its peduncle with surgical scalpel under local anesthesia without teeth extraction. The base was evacuated and the bone thoroughly curetted, and the healthy gingiva was sutured over it. Macroscopically, the epulis appeared as a lobulated mass, which on cut surface appears fibrous with a shiny gray-to-white aspect (<xref ref-type="fig" rid="fig3">Figure 3a</xref>).</p><p>The mass was fixed in 10% neutral buffered formalin solution and embedded in paraffin. Five-micrometer sections were obtained and submitted for routine hematoxylin–eosin staining. On microscopic examination, the lesion appeared densely fibrous with inconspicuous proliferating fibroblasts and moderate lymphoplasmacytic infiltrate and vascular dilatation. The connective tissue was fat infiltrated (<xref ref-type="fig" rid="fig3">Figure 3b</xref>). Epithelium was hyperplastic (acanthosis) and partially ulcerated with deposition of a fibrinopurulent exudate. There was no evidence of ossification or calcified structures. These findings were suggestive of a reactive localized inflammatory hyperplasia consistent with a fibrous epulis.</p><p>The patient had an uneventful postoperative recovery with minimal scarring. She has been following up with us at regular intervals and for the last year and is without any recurrence at the time of this report (<xref ref-type="fig" rid="fig4">Figure 4</xref>).</p></sec><sec sec-type="discussion"><title>DISCUSSION</title><p>The most common clinical aspect of the fibrous epulis is the growth of well-delimited tissue, of a smooth surface, usually with normal colored mucosa, sessile or pedunculated base, of hard consistence, usually located on the anterior maxillary, in the interdental papilla.<sup><xref ref-type="bibr" rid="bib2">2</xref>,<xref ref-type="bibr" rid="bib6">6</xref>,<xref ref-type="bibr" rid="bib7">7</xref></sup> Though these characteristics are consistent with our case, report of a fibrous epulis with this size<sup><xref ref-type="bibr" rid="bib8">8</xref>,<xref ref-type="bibr" rid="bib9">9</xref>,<xref ref-type="bibr" rid="bib10">10</xref></sup> or long evolution are unusual.<sup><xref ref-type="bibr" rid="bib7">7</xref></sup></p><p>There is some question as to whether this lesion represents a neoplasm or a reactive condition. The histopathological findings are consistent with Tajima,<sup><xref ref-type="bibr" rid="bib3">3</xref></sup> where the fibrous epulis was composed of proliferating fibroblasts and collagen fibers with a minimal degree of inflammatory cell infiltration and vascular dilatation. This evidence is the most reliable condition to make the differential diagnosis. Although several authors reported cases of an epulis-like neoplasm, the collagenous fibroma (desmoplastic fibroblastoma) originated in the oral cavity;<sup><xref ref-type="bibr" rid="bib11">11</xref>,<xref ref-type="bibr" rid="bib12">12</xref>,<xref ref-type="bibr" rid="bib13">13</xref></sup> we agree with these authors that the collagenous fibroma is a rare entity, without signs of inflammation. Nevertheless, considering the fibrous epulis, we disagree with Shimoyama <italic>et al.</italic><sup><xref ref-type="bibr" rid="bib11">11</xref></sup> that the size distinct neoplasm. This case demonstrates that the epulis can attain an unusually large size causing considerable facial deformity, an extreme and unusual presentation of a reactive condition. The biggest challenge as a clinician is arriving at a definitive diagnosis.<sup><xref ref-type="bibr" rid="bib4">4</xref></sup> The gingiva is commonly affected by non-neoplastic and neoplastic lesions, the latter usually being characterized by a progressive growth that can be either benign or malignant. Moreover, the great majority of localized overgrowths of the gingiva are considered to be reactive rather than neoplastic in nature.<sup><xref ref-type="bibr" rid="bib14">14</xref></sup></p><p>Fibrous inflammatory hyperplasias may occur on any surface of the oral mucous membrane as either pedunculated or sessile growth. On the gingiva, a similar lesion is often referred to as an epulis, that is, a growth on the gum. The majority remain small, and lesions more than 1 cm in diameter are rare on the cheeks, tongue and floor of the mouth possibly because masticatory trauma restricts their size through necrosis and ulceration.<sup><xref ref-type="bibr" rid="bib1">1</xref></sup> Several authors observed that irritation fibroma is more common in adult females. Also, their research found no marked difference in location of irritation fibroma between upper and lower jaws.<sup><xref ref-type="bibr" rid="bib1">1</xref>,<xref ref-type="bibr" rid="bib15">15</xref></sup> Carbone and colleagues<sup><xref ref-type="bibr" rid="bib14">14</xref></sup> reported a significant higher frequency and site distribution in maxilla than the mandible (9/2).</p><p>Treatment usually includes complete excision of the lesion and thorough curettage of the area due to its origin from the periosteum and periodontal ligament cells to prevent recurrence. The extraction of the neighboring teeth is usually not considered necessary unless there is extensive underlying bony involvement.<sup><xref ref-type="bibr" rid="bib1">1</xref>,<xref ref-type="bibr" rid="bib4">4</xref>,<xref ref-type="bibr" rid="bib7">7</xref>,<xref ref-type="bibr" rid="bib16">16</xref></sup> The most widely used instruments are a surgical or electric scalpel, but in cases where an important vascular component of the lesion is suspected intraoperatively, the electrical scalpel or CO<sub>2</sub> laser are theoretically of choice since they afford a bloodless surgical field.<sup><xref ref-type="bibr" rid="bib16">16</xref></sup> In this case, the simple but controlled excision of the minimum peduncle with a surgical scalpel and a basic good suture technique allowed reducing the risk of hemorrhage. We believe that the controlled excision of adjacent periodontal membrane, periostium and alveolar bone, and the root planning performed to eliminate irritations were essential to avoid the recurrence. A conservative surgical excision with gingival recontouring was preferred because of the absence of bone invasion and the obviously aggressiveness of the classical surgery.</p><p>The term ‘epulis' (from the Greek words ‘<italic>epi</italic>' –over– and ‘<italic>oulon</italic>' –gums–) was first used by Virchoff in 1864, and it has generated great controversies in its use.<sup><xref ref-type="bibr" rid="bib7">7</xref>,<xref ref-type="bibr" rid="bib16">16</xref></sup> The International Classification of Diseases is published by the World Health Organization, and it is used to promote the international comparability in the classification of the conditions to be most suitable for general epidemiological purposes and evaluation of health care. According to the current tenth revision (ICD-10), the ‘Fibrous epulis' is coded as a type of ‘other disorders of the gingival and edentulous ridge' (K06.8).<sup><xref ref-type="bibr" rid="bib17">17</xref></sup> We coincide with Tamarit-Borràs and collegues<sup><xref ref-type="bibr" rid="bib16">16</xref></sup> where the word ‘hyperplasia' is more appropriate since it refers to tissue growth on these cases, where the determination of the duration of the lesion and its chronic irritative etiological factor turn on the magnitude of the existing fibrous component. In fact, the term ‘reactive localized inflammatory hyperplasia' has been used more appropriately to describe lesions such as pyogenic granuloma/pregnancy tumor, calcifying fibroblastic granuloma, peripheral ossifying fibroma, fibrous-epithelial polyp, fibrous hyperplasia, denture irritation hyperplasia (epulis fissuratum), peripheral giant cell granuloma and the fibrous epulis.<sup><xref ref-type="bibr" rid="bib15">15</xref></sup></p></sec><sec sec-type="conclusions"><title>CONCLUSION</title><p>In some cases, the dentist may be the first health care professional to detect this oral lesion.<sup><xref ref-type="bibr" rid="bib16">16</xref></sup> In our case, even though 12 odontologists misdiagnosed and/or refused the treatment, it involved a simple resection with gingival recontouring and control of the local irritating factor to prevent recurrence. We can conclude that a thorough knowledge about various aspects of a gingival lesion is the key to a successful diagnosis and treatment planning.<sup><xref ref-type="bibr" rid="bib4">4</xref></sup> Because of the unusual size, discussion and consideration of the various differential diagnoses should be done tactfully to prevent unnecessary distress to the patient and family.<sup><xref ref-type="bibr" rid="bib7">7</xref></sup></p></sec></body><back><ack><p> We appreciate the financial support received from the Program of Attraction and Insertion of Advanced Human Resources, MEC—Conicyt (80120014).</p></ack><ref-list><ref id="bib1"><mixed-citation publication-type="journal"><person-group person-group-type="author"><name><surname>Pour</surname><given-names>MA</given-names></name><name><surname>Rad</surname><given-names>M</given-names></name><name><surname>Mojtahedi</surname><given-names>A</given-names></name></person-group><article-title>A survey of soft tissue tumor-like lesions of oral cavity: a clinicopathological study</article-title><source>Iran J Pathol</source><year>2008</year><volume>3</volume><supplement>2</supplement><fpage>81</fpage><lpage>87</lpage></mixed-citation></ref><ref id="bib2"><mixed-citation publication-type="journal"><person-group person-group-type="author"><name><surname>Ajagbe</surname><given-names>HA</given-names></name><name><surname>Daramola</surname><given-names>JO</given-names></name></person-group><article-title>Fibrous epulis: experience in clinical presentation and treatment of 39 cases</article-title><source>J Natl Med Assoc</source><year>1978</year><volume>70</volume><supplement>5</supplement><fpage>317</fpage><lpage>319</lpage><pub-id pub-id-type="pmid">702565</pub-id></mixed-citation></ref><ref id="bib3"><mixed-citation publication-type="journal"><person-group person-group-type="author"><name><surname>Tajima</surname><given-names>H</given-names></name></person-group><article-title>A histopathological and immunohistochemical study of pathological ossification in epulis osteoplastica</article-title><source>Oral Med Pathol</source><year>2009</year><volume>13</volume><supplement>3</supplement><fpage>91</fpage><lpage>98</lpage></mixed-citation></ref><ref id="bib4"><mixed-citation publication-type="journal"><person-group person-group-type="author"><name><surname>Rajanikanth</surname><given-names>BR</given-names></name><name><surname>Srinivas</surname><given-names>M</given-names></name><name><surname>Suragimath</surname><given-names>G</given-names></name><etal></etal></person-group><article-title>Localized gingival enlargement—a diagnostic dilema</article-title><source>Indian J Dent</source><year>2012</year><volume>3</volume><supplement>1</supplement><fpage>44</fpage><lpage>48</lpage></mixed-citation></ref><ref id="bib5"><mixed-citation publication-type="journal"><person-group person-group-type="author"><name><surname>Liu</surname><given-names>C</given-names></name><name><surname>Qin</surname><given-names>ZP</given-names></name><name><surname>Fan</surname><given-names>ZN</given-names></name><etal></etal></person-group><article-title>New treatment strategy for granulomatous epulis: intralesional injection of propranolol</article-title><source>Med Hypotheses</source><year>2012</year><volume>78</volume><supplement>2</supplement><fpage>327</fpage><lpage>329</lpage><pub-id pub-id-type="pmid">22133559</pub-id></mixed-citation></ref><ref id="bib6"><mixed-citation publication-type="journal"><person-group person-group-type="author"><name><surname>Kfir</surname><given-names>Y</given-names></name><name><surname>Buchner</surname><given-names>A</given-names></name><name><surname>Hansen</surname><given-names>LS</given-names></name></person-group><article-title>Reactive lesions of the gingiva.
