lesion, histopathological diagnosis was squamous cell carcinoma.Treatment was mandibular resection and radiotherapy. Althoughmetastasis was not present, treatment was radical, evidence of theneed for early diagnosis to obtain a better prognosis.
PE-191 - LEIOMYOSARCOMA IN THE BUCCALMUCOSA. JOSÉ NARCISO ROSA ASSUNÇÃO JUNIOR,PRISCILA LIE TOBOUTI, MARILIA TRIERVEILERMARTINS, HAROLDO ARID SOARES, CELSO AUGUSTOLEMOS. FACULDADE DE ODONTOLOGIA DE SANTOS-UNIMES/FACULDADE DE ODONTOLOGIA DA USP.
Black woman, 39, had an asymptomatic nodule in the leftbuccal mucosa for 18 months. She reported an asymptomatic,slow-growing lesion, with mild, sporadic paresthesia in the area.A submucosal asymptomatic fibrous nodule 1 cm in diameter andcovered by regular mucosa was observed at intraoral examination.The clinical diagnosis was a benign neoplasm of the salivarygland X neural benign neoplasia. Histopathological examinationrevealed a fragment of a mesenchymal neoplasia formed by adense proliferation of fusiforms cells with stretched cell nuclei.Cell and nuclei polymorphism was observed, along withnumerous atypical mitoses and a coagulated necrotic region. Theimmunohistochemical reaction was positive to smooth muscleactin, HHF35, and laminine and negative to S-100, CD-34, anddesmine. KI-67 level was high (over 20%). The neoplasm pre-sented 10 mitoses/10 sites at 400� magnification. The definitivediagnosis was leiomyosarcoma. The patient was referred to anoncologic hospital for treatment.

Leopard syndrome (multiple lentigines syndrome) is adominant autosomal disorder that results in skin and skeletalproblems and problems with the cardiovascular system. LEOP-ARD is an acronym for manifestations of the syndromeelentigines, electrocardiographic abnormalities, ocular hyper-telorism, pulmonary stenosis, abnormal genitalia, retardedgrowth, and deafness. Clinical diagnosis is based on lentiginesand two other symptoms or, in cases where lentigines is absent,three other symptoms and at least one of the parents having thedisorder in the first degree. Twin white men, 21, had multiplelentigines syndrome. The paternal grandmother has the syndromeand the father had lentiginosis. The patients present multiplelentigines on the skin, ocular hypertolorism, abnormal genitalia,intellectual deficiencies, delayed speech, and visual disabilities.Oral examination found mandibular retrognathia. Because of theirvarious problems, the patients are being treated according to amultidisciplinary approach, including orthodontic treatment.
PE-193 - LICHEN PLANUS ASSOCIATED WITHCHRONIC HEPATITIS C: DIFFICULT DIAGNOSIS ANDMANAGEMENT OF A CASE.

Man, 61, came to the Universidade Vale do Rio Verdecomplaining of “pain in the tongue.” The patient had chronichepatitis C and also reported difficulty in speaking and feedingand loss of taste sensation. Intraoral examination noted ulcerationin almost all tongue areas and extreme symptoms associated withwhite plaques, which developed over 2 years. The clinical find-ings and medical history yielded primary diagnostic hypothesis oferosive lichen planus associated with secondary Candida infec-tion. The patient was initially prescribed topical Nystatin; after 7days an incisional biopsy was performed. Because the symptomsgrew worse, dexamethasone was prescribed. The histopatholog-ical examination revealed an inflammatory process but did notyield a definitive diagnosis. The patient was prescribed systemicand topical dexamethasone and a new biopsy was performed. Heis now being followed in our service. (Support: CNPq; Fapemig).
PE-194 - LICHENOID REACTIONS OF THE ORALCAVITY: A DIFFICULT DIAGNOSIS, PRESENTATIONOF TWO CASES, AMALGAM AND CINNAMONLICHENOID REACTION.

Lichenoid reaction is a common entity among skin pathol-ogies but a relatively rare condition in the oral mucosa. Amalgamrestorations, foods, mouthwashes, toothpastes, synthetic resin,and topical treatments can act as triggering factors in oral mucosalcases. However, the clinical diagnosis remains a challengebecause of the clinical similarity between lichenoid reactions andoral lichen planus. Two cases of lichenoid lesions will be pre-sented: the first one was an allergic reaction caused by thecomponents of amalgam restorations and the second one a reac-tion to chronic cinnamon contact. Both were localized in thebuccal mucosa. Lichenoid reactions are alterations in the mucosaltissue resulting from hypersensitivity to some chemical compo-nents, whereas lichen planus shows patterns such as white stria-tions, erythema, erosions, white papules, or plaques. Besidespresenting two cases, this report discusses the diagnosis andclinical findings of these contact allergy reactions.
PE-195 - LOCAL RECURRENCE OF SQUAMOUS CELLCARCINOMA AND IMPORTANCE OF FOLLOW-UP:REPORT OF FOUR CASES.

Squamous cell carcinoma (SCC) has low recurrence aftertreatment and the elimination of deleterious habits. Four cases ofSCC are reported in which the patient developed local recurrenceafter treatment. Man, 68, who had radiotherapy in 2008 demon-strated a reddish lesion on the soft palate. Histological exami-nation showed “carcinoma in situ” (2011). Woman, 66, who hadradiotherapy in 2007, presented a whitish verrucous lesion on theleft side of the hard palate. Histological characteristics werecompatible with “carcinoma in situ” (2013). Woman, 53, under-went radiotherapy and chemotherapy in 2005, then presented anulcerated lesion on the tongue. Oral biopsy was diagnostic forspeckled leukoplakia with severe dysplasia (2011). Man, 71, hadradiotherapy in 2009, then developed an ulcerated lesion on the
