OOOO Volume 129, Number 1 ACQUIRED ORAL SYPHILIS: REPORT OF 2 CASES AND REVIEW OF THE LITERATURE. ^ LENI VERONICA DE OLIVEIRA SILVA, JOSE ALCIDES ALMEIDA DE ARRUDA, LAUREN FRENZEL SCHUCH, ADRIANA APARECIDA SILVA DA COSTA, FELIPE PAIVA FONSECA and, RICARDO ALVES MESQUITA Acquired oral syphilis (AOS) is an infectious disease caused by the bacterium Treponema pallidum. Transmission occurs mainly by sexual contact with infectious lesions. Two cases of AOS have been reported. A 29-year-old male patient presented with grayish-white mucous patches and reddish ulcers in the lips, lateral border of the tongue, floor of the mouth, and the oropharynx. The patient was a marijuana user. A 33-year-old female patient presented with pruritus of the tongue and throat, pain in the upper labial mucosa for 1month, and halitosis. Reddish ulcers 5 mm in size were detected in the upper labial mucosa, posterior dorsal surface of the tongue, gingiva, and palate. A maculopapular cutaneous rash was also observed. The patients did not report systemic comorbidities. Venereal Disease Research Laboratory (VDRL) and fluorescent treponemal antibody absorption (FTAABS) were both positive, confirming the clinical diagnosis of syphilis. They patients were referred for adequate treatment and remission of the oral lesions was observed. Support: FAPEMIG.
MELKERSSON-ROSENTHAL SYNDROME: A CASE REPORT. LAUREN FRENZEL SCHUCH, FELIPE PAIVA FONSECA, EDUARDO MORATO DE OLIVEIRA, JOSE ALCIDES ALMEIDA DE ARRUDA, PATRICIA CARLOS CALDEIRA and, MARIA CASSIA FERREIRA DE AGUIAR A 20-year-old white man was referred to the oral medicine clinic, complaining of an asymptomatic swelling in the upper lip lasting for around 2 years. His medical history included stressinduced gastritis, bronchitis, allergic rhinitis, and episodes of facial paralysis. The extraoral examination showed a large and diffuse swelling affecting the upper lip vermillion and labial mucosa causing facial asymmetry. The lesion was nonpitting, had a rubbery consistency, and presented with a normal temperature. The vermillion border was dried and stretched, with no ulceration. The intraoral examination revealed deep grooves and fissures on the tongue dorsum. A previous biopsy of the lip showed a chronic inflammatory area. Based on the history and clinical features, the diagnosis of Melkersson-Rosenthal syndrome was made. The patient is under treatment with intralesional infiltration of triamcinolone acetonide in the upper lip. Moreover, he was referred for a physician to investigate a possible intestinal involvement.

CLINICOPATHOLOGIC AND IMMUNOHISTOCHEMICAL CHARACTERIZATION OF LOCALIZED JUVENILE SPONGIOTIC GINe GIVAL HYPERPLASIA.

often involves the anterior gingiva of the upper maxillary. Its origin is controversial, and neither infectious nor hormonal factors have been recognized. Clinically, it appears as an irregular papillary and reddish mass. We present a series of 10 cases, 5 women and 5 men, whose mean age was 13 years. We analyze their main clinical and histologic characteristics, as well as their immunochemical profile (CK14, CK17, CK19, CD3, CD20, S100, VEGFa, and ki-67), with the aim of explaining its origin and possible etiopathogenesis. Based on obtained data, the results show that LJSGH is not an epuliform lesion of a reactive nature, but a specific clinicopathologic entity, strongly related to persistency of the junctional epithelium. This research was supported by a Research Group from UPV/EHU (PPG17/01).
FABRY DISEASE: ORAL FINDINGS AND POSSIBLE ASSOCIATION WITH AUTOIMMUNE DESQUAMATIVE GINGIVITIS. ADEMAR TAKAHAMA JUNIOR, GUILHERME LUCIANO DA SILVA, HELITON GUSTAVO DE LIMA and, FABIO AUGUSTO ITO Fabry disease is an X-linked metabolic disease caused by the deficiency of the lysosomal enzyme a-galactosidase A. We report a case of a 55-year-old woman, with previous diagnosis of Fabry disease that was referred complaining of pain in the gingiva for about 1 year. The physical examination revealed short fingers, angiokeratomas in the neck, fissured tongue and desquamative gingivitis. An incisional biopsy was performed in the gingival lesions and the histopathologic analysis revealed a subepithelial blister, compatible with the diagnosis of mucous membrane pemphigoid. A topical corticosteroid therapy was instituted associated with conventional periodontal treatment. After 3 weeks, all areas of erythema or ulceration were healed, and the symptoms had disappeared. Fabry disease is a rare disorder with a few cases of oral abnormalities described. A high incidence of autoantibodies has been reported in patients with Fabry disease, which may explain the development of the desquamative gingivitis condition.
VASCULAR EXTENSION OF PERIPHERAL GIANT CELL LESION: A CASE REPORT WITH IMMUNOHISTOCHEMICAL ANALYSIS. e STEPHANY PIMENTA CARVALHO, RICARDO NATA FONSECA SILVA, WILSON JOSE MARIANO JUNIOR, SARA CRISTINA DE ARAUJO, THAIS LANUSSE MELGACO, ¸ NADIA DO LAGO COSTA and, ENEIDA FRANCO VENCIO Peripheral giant cell lesions shares microscopic similarities to other entities and their origin remains unclear. A 47-year-old woman was referred for management of a painful swelling in the canine region with recent history of tooth removal. A slight asymmetry in the upper lip was detected. Intraoral exam revealed a lesion that appeared as a purplish-red nodule, pediculate on the anterior right alveolar crest, and associated with an unstable dental prosthesis. Superficial bone resorption was detected. The lesion was curetted after excision biopsy. Microscopically, an ulcerative, nonencapsulated lesion composed of densely cellular lobules of round mononuclear cells, prominent multinucleated giant cells (MGCs), and hemorrhage was surrounded by fibrous tissue. Apoptotic MCGs were also seen. Interestingly, vessels in the periphery exhibited transendothelial migration of MGCs were positive for matrix metallopeptidase 9 (MMP-9) and
