JULY 4-8, 2016 538 ABSTRACTS OP – ORAL PRESENTATION 043 CPP – CLINICAL POSTER PRESENTATION 344 RESEARCH POSTER 151 OP01 - BROWN TUMOR OF THE JAW MIMICKING MALIGNANT NEOPLASM. Paulo de Camargo MORAES. Rubens GONÇALVESTEIXEIRA. Luis Alexandre THOMAZ. Claudio Roberto Pacheco JODAS. Victor Angelo MONTALLI. Marcelo SPERANDIO. Amy Louise BROWN. Brown tumors are an unusual manifestation of primary hyperparathyroidism, a disease characterized by excessive secretion of parathyroid hormone (PTH). With the exception of bone loss, skeletal manifestations are rare, occurring in less than 2% of patients. The presence of multiple lesions may imitate a malignant neoplasm, hence posing a real diagnostic challenge. We describe a 50-year-old wheelchair-bound Brazilian woman, presenting multiple expansive lytic lesions. The clinical differential diagnosis included metastatic disease and multiple myeloma. Intra-oral examination revealed a large ulcerating proliferative brown mass on the left side of the mandible, with significant bone destruction. Serum calcium, alkaline phosphatase and PTH (was seven times above the upper limit of normal). A combination of physical examination, and radiological and histopathologyc investigations were performed. A parathyroid nodule was detected and surgically excised. Two months later the patient no longer wheelchair-bound. In addition, after 15 months of follow-up the brown tumour has significantly decreased. OP02 - LEISHMANIOSE IN ORAL CAVITY - A CASE CLINICAL REPORT. Carlos Deyver de Souza QUEIROZ. Helio Massaiochi TANIMOTO. Raphael HAIKEL JUNIOR. Edmundo Carvalho MAUAD. André Lopes CARVALHO. José Humberto FRAGNANI. Adhemar LONGATTO FILHO. Leishmaniasis is an infectious disease A, non-contagious, caused by different species of Leishmania protozoa, which can affect the skin and / or mucous membranes. When it affects the oral mucosa disease becomes destructive or ulcerovegetativa and granulomatous The goal is to report a clinical case and the difficulty of performing diagnosis of leishmaniasis in remote regions. Patient NF male, 61 years old, leucoderma, coming from Porto dos Gauchos MT, was referred to the Prevention department in Mouth Cancer by teledermatology with ulcerovegetativa injury and granulomatous in hard and soft palate, more than 1 year already had undergone prior treatment without improvement, we performed incisional biopsy and material sent for pathology whose result was consistent with leishmaniasis, compulsory notification was made and sent to medical reference treatment center, after 6 months of treatment returned for reassessment, where he observed the curing the disease without lesions in the oral cavity.

Roberta Oliveira de Paula e SILVA. Ricardo Santiago GOMEZ. Ricardo Alves MESQUITA. Multiple myeloma (mm) is a systemic disease characterized by multifocal proliferation of atypical plasma cells and production of monoclonal immunoglobulins. A 51-year-old caucasian male presented to referral center, complaining of pain in the left mandible. During physical examination, an increased volume at the inferior vestibule fornix, with painfull and hard consistency at palpation was observed. A panoramic radiograph showed a circular osteolytic lesion in the left mandible. The medical history revealed a previously diagnosis of mm, treated with autologous stem cell transplantation in 2014. An incisional biopsy was taken with previous puncture and aspiration. The histopathological analysis revealed atypical plasma cells with large hyperchromatic nuclei and large cytoplasm. The diagnosis was malignant neoplasm of plasma cell. Based on all the reports and laboratory findings, a final diagnosis of relapsed mm was made. The patient was referred for medical treatment. (CNPq #309322/2015-4 FAPEMIG). 1 OP4 - MINERAL AND OSSEOUS DISORDERS RELATED TO CHRONIC KIDNEY DISEASE: A CASE REPORT WITH ORAL HEALTH IMPACT. Fernanda Tenório Lopes BARBOSA. Alexandre BELLOTTI. Eneida Franco VÊNCIO. Rejane Faria RIBEIRO-ROTTA. Jaw enlargement is a not common reported complication of chronic kidney disease mineral and bone disorder. A 24y man was referred to an oral medicine center presenting a large asymptomatic anterior mandible growing, 2 months of evolution. Medical history included chronic kidney disease and high blood pressure since 6 years ago. Laboratory examinations revealed high levels of parathormone and endocrinologist diagnosed as secondary hyperparathyroidism. Histopathological examination of incisional biopsy from the mandible lesion reported a cluster of spindle cells with numerous giant multinucleated cells, and peripheral osteoid formation, compatible with brown tumor of hyperparathyroidism. Phosphorus levels control through diet, chelating agents and the use of vitamin D analogues were therapeutic approaches, which have failed due to lack of adherence to treatment. Parathyroidectomy was considered, but patient died before the intervention due to pulmonary embolism. Multidisciplinary professional integration was crucial to ensure patient´s quality of life during treatment. OP5 - COWDEN´S SYNDROME, A RARE CONDITION: CASE REPORT. Arthur Wilson Florencio da COSTA. Marília Oliveira MORAIS. Allisson Filipe Lopes MARTINS. Inara Carneiro Costa REGE. Elismauro Francisco de MENDONÇA. Cowden's syndrome (CS) is a rare genodermatosis that affects the female gender and caucasian patients. The skin is the organ most affected and these cutaneous manifestations usually precede the development of cancer serving as important clinical signs in identifying patients at high risk for developing malignancies. Our goal is to present the case of a female patient and 53 years with a chief complaint of "infection in the mouth and burning sensation in the tongue". medical history showed conducting tireodectomia, removal of in-ear harmartoma and liver nodule. On examination extraoral sessile nodule in the ear and intraoral multiple coloring papules similar to the mucosa. Performed incisional biopsy and histopathology compatible with inflammatory fibrous hyperplasia. The final diagnosis was SC associated with oral candidiasis. The patient was treated with Nystatin to control the infection and currently is under observation for two years without complaints or deteriorations in the frame. OP6 - POLYMORPHOUS LOW GRADE ADENOCARCINOMA OF THE LOWER LIP. Tiago Novaes PINHEIRO. Claudia Andrea Garcia Corrêa SIMÕES. Antonio Jorge Araújo Vasconcelos II. Marco Túllio BRAZÃO-SILVA. Polymorphous low grade adenocarcinoma (PLGA) is a malignant neoplasm that frequently occurs in the minor salivary glands in palate and oral cavity. We present a case of lower lip swelling with ulceroproliferative growth in a 48 year old male with more than 20 years history of development. Fine needle aspiration cytology smears suggested salivary gland neoplasia. A wide incisional biopsy was performed and histopathological examination diagnosed PLGA. The patient was referred to a oncology center and still under follow-up for the last six month. The differential diagnosis of PLGA with pleomorphic adenoma, adenoid cystic carcinoma, mammary analogue secretory carcinoma, mucoepidermoid carcinoma, epithelial myoepithelial carcinoma and papillary cystadenocarcinoma is discussed as well as significance of different histochemical techniques for microscopic diagnosis. OP7 - EIGHT-YEAR FOLLOW-UP OF CENTRAL GIANT CELL LESION TREATED WITH CORTICOSTEROID. CASE REPORT. Juliana BORGES. Tila FORTUNA COSTA. Silvia REIS. Antônio Márcio Teixeira MARCHIONNI. Briana MONTEIRO. Alena Peixoto MEDRADO. This paper aims to report a case of a pediatric patient with central giant-cell granulomas of the jaw, which was successfully treated with intralesional corticosteroid injections as it's only therapy and discuss if there is an ideal waiting period between nonoperative treatment and the need for surgical intervention. An eight-year-old boy with a central giant cell lesion on the right side of the mandible was treated with intralesional corticosteroids injections. After an eight-year follow-up, 2 the patient´s bony architecture was near normal. The panoramic radiography showed areas of new bone formation and neither recurrence nor side effects of the medication have been also detected. Is there an ideal waiting period between nonoperative treatment and the need for surgical intervention? It is estimated that a monitoring period of 6-8 years is necessary to determine the success of such treatment. OP8 - SURGICAL CILIATED CYST: A CASE REPORT. José Alcides Almeida de ARRUDA. Saulo Queiroz de ARAUJO. Thiago Coelho Gomes da SILVA. Belmiro Cavalcanti do Egito VASCONCELOS. Marcia Maria Fonseca da SILVEIRA. Ana Paula Veras SOBRAL. Surgical ciliated cyst is often described as a post-operative maxillary cyst or paranasal cyst. Characterized by an aggressive injury, it is commonly described in patients who underwent radical surgery on the maxillary sinus region, such as orthognathic or Caldwell-Luc procedures. We report a case of a 47-year-old patient complaining of both spontaneous pain and swelling in the anterior maxilla, presenting a history of a 9-month-old surgery in the posterior maxilla intended to remove an odontogenic cystic lesion. The CT scan visualized a hypodense lesion in the left maxillary sinus region. Performed biopsy and histopathological

  • New Aspects of Cutaneous Mosaicism
    The Journal of Dermatology Vol. 29: 681–692, 2002 Dohi Memorial Lecture New Aspects of Cutaneous Mosaicism Rudolf Happle Abstract The concept of cutaneous mosaicism has today been proven at the cellular level in at least fifteen different skin disorders. We can distinguish five different patterns of mo- saicism, including the phylloid pattern and the lateralization pattern. Etiologically, cuta- neous mosaics can be divided into two large categories, epigenetic mosaicism and genom- ic mosaicism. All forms of epigenetic mosaicism known so far, including the various pat- terns of X-inactivation, appear to be caused by the action of retrotransposons. A new con- cept is functional autosomal mosaicism transmittable through the action of retrotrans- posons, which has been described in mice and dogs and may explain, for example, the fa- milial occurrence of pigmentary mosaicism along the Blaschko lines in human skin. Among the examples of mosaicism of autosomal lethal mutations, phylloid hypomelanosis is a recently recognized neurocutaneous entity caused by mosaic trisomy 13. Possible ex- amples of a type 2 segmental manifestation now include at least fifteen different autoso- mally dominant skin disorders. This phenomenon is most frequently found in gloman- giomatosis, cutaneous leiomyomatosis, and disseminated superficial actinic porokeratosis. Recently proposed examples of didymosis (twin spotting) include cutis tricolor, paired patches of excessive or absent involvement in Darier disease, and didymosis aplasticose- bacea characterized by coexistent aplasia cutis congenita and nevus sebaceus. To the list of possible examples of paradominant inheritance, cutis marmorata telangiectatica congeni- ta and speckled lentiginous nevus syndrome have now been added. Revertant mosaicism giving rise to unaffected skin areas in autosomally recessive cutaneous traits will certainly likewise be recognized more often when clinicians are bearing this concept in mind.

  • Cutaneous Squamous Cell Carcinoma in the Age of Immunotherapy
    cancers Review Cutaneous Squamous Cell Carcinoma in the Age of Immunotherapy Yosuke Ishitsuka * , Yuma Hanaoka, Atsushi Tanemura and Manabu Fujimoto Department of Dermatology Integrated Medicine, Osaka University Graduate School of Medicine, 2-2 Yamadaoka, Suita, Osaka 565-0871, Japan; [email protected] (Y.H.); [email protected] (A.T.); [email protected] (M.F.) * Correspondence: [email protected]; Tel.: +81-66-879-3031; Fax: +81-66-879-3039 Simple Summary: Cutaneous squamous cell carcinoma (cSCC) is the second most prevalent skin cancer globally. Immunosuppression raises cSCC incidence rates, while high immunogenicity of the cutaneous tissue enables topical immunotherapy. Intriguingly, expanded applications of programmed death-1 (PD-1) blockade therapies have revealed cSCC to be one of the most amenable targets. These clinical observations prompted us to redefine cSCC biology and review current knowledge about cSCC from multiple viewpoints that involve epidemiology, clinicopathology, molecular genetics, molecular immunology, and developmental biology. This synthesis reinforces the following hypothesis: PD-1 blockade effectively restores the immunity specially allowed to exist within the fully cornified squamous epithelium, that is, the epidermis. Abstract: Cutaneous squamous cell carcinoma (cSCC) is the second most prevalent skin cancer glob- ally. Because most cSCC cases are manageable by local excision/radiotherapy and hardly become life-threatening, they are often excluded from cancer registries in most countries. Compared with Citation: Ishitsuka, Y.; Hanaoka, Y.; cutaneous melanoma that originates from the melanin-producing, neural crest-derived epidermal Tanemura, A.; Fujimoto, M. resident, keratinocyte (KC)-derived cancers are influenced by the immune system with regards to Cutaneous Squamous Cell their pathogenetic behaviour.

See Table 2 for genes and associated conditions. Most mutations in the genes analyzed are somatic in origin. These mutations are often post-zygotic leading to mosaicism and are poorly detected in the blood. These mutations are better detected in a clearly affected tissue (skin, muscle, adipose, central nervous system). Submission of affected tissue is strongly recommended to increase sensitivity. The cost of testing includes up to two samples (additional samples may be tested for an additional cost- please call the lab for this information). Somatic Overgrowth NGS Panel Assay and Limitations: Capture-based target enrichment and Next Generation Sequencing on Illumina MiSeq platform including 34 genes: AKT1, AKT2, AKT3, BRAF, CCM2, CCND2, CDKN1C, FGFR1, FGFR2, FGFR3, FLT4, GLMN, GNA11, GNA14, GNAQ, HRAS, IDH1, IDH2, KDR, KRAS, KRIT1, MAP2K1, MAP3K3, MTOR, NRAS, PDCD10, PIK3CA, PIK3R1, PIK3R2, PTEN, RASA1, SMO, STAMBP, TEK. See Table 2 for genes and associated conditions. The limit of variant allele detection is 1% at 2500x read depth and the threshold for mutation detection is set at 10 reads without strand bias.

    507 CONTINUING MEDICAL EDUCATION ▲ Cutaneous mosaicisms: concepts, patterns and classifications* Mosaicismos cutâneos: conceitos, padrões e classificações Samara Silva Kouzak1 Marcela Sena Teixeira Mendes2 Izelda Maria Carvalho Costa3 DOI: http://dx.doi.org/10.1590/abd1806-4841.20132015 Abstract: A mosaic is an organism composed of two or more genetically distinct cell populations derived from a genetically homogeneous zygote. Cutaneous mosaicisms are the clinical expressions of these disorders. The main event which allows the existence of mosaicism is a genetic mutation, either structural or functional. Cutaneous mosaicisms usually manifest by specific patterns on the skin and the archetypic pattern is the system of Blaschko lines, but others include checkerboard, phylloid, large patches without midline separation and lateralization. Since 1901, when Blaschko lines were first described, the study of mosasicism has helped to elucidate the behavi- or of numerous genetic diseases, generating therapeutic perspectives for these pathologies, including the promi- sing gene therapy. Keywords: Focal dermal hypoplasia; Incontinentia pigmenti; Loss of heterozygosity; Mosaicism; Nevus Resumo: Um mosaico é um organismo formado por duas ou mais populações de células geneticamente distintas originadas a partir de um mesmo zigoto geneticamente homogêneo. Os mosaicismos são as expressões clínicas dessa desordem, e a mutação gênica seu evento determinante, que pode ser tanto estrutural quanto funcional. Os mosaicismos cutâneos costumam se expressar em padrões específicos, dentre os quais podem ser mencionados as prevalentes linhas de Blaschko, o padrão "checkerboard", o padrão filóide, o padrão em placa sem separação na linha média e o padrão de lateralização, que serão abordados neste artigo. Desde 1901, momento da primeira des- crição das linhas de Blaschko, o estudo dos mosaicismos tem contribuído para a elucidação do comportamento de numerosas desordens genéticas, de forma a criar perspectivas terapêuticas para essas doenças, incluindo a pro- missora terapia gênica.

It frequently involves scalp, but sebaceous nevi may also emerge on the neck, face or forehead. It comprises of the overgrown epidermis (upper skin layer), sebaceous glands, hair follicles, apocrine glands and connective tissue. Linear sebaceous nevus syndrome rarely reveals any oral manifestation. A sebaceous nevus is also called an organoid nevus because it may comprise components of the entire skin. We report a case of linear sebaceous nevus syndrome in a 14-year-old female patient with abnormal oral findings.
