Histopathologically, it reveals 2 types of cells, fibroblasts and histiocytes, arranged in storiform pattern and interlacing fascicles without nuclear pleomorphism, necrosis, and low mitotic activity. The granular cell variant of BFH is extremely rare. A 64-year-old woman was referred presenting an osteolytic lesion in the anterior region of the maxilla, mimicking nasopalatine duct cyst. After excisional biopsy, microscopy revealed a storiform arrangement of spindle to epithelioid cells, most of them with PAS-D positive granular cytoplasm, surrounded by sclerotic fibrous stroma. Immunohistochemistry showed positivity for vimentin, CD68, CD163, a smooth muscle actin, and focal FXIIIA. Ki-67 was <3%. The patient presented well after 1-year of follow-up. To our knowledge, this is the first report of BFH rich in granular cells in intraosseous location affecting the maxilla.
LASER THERAPY FOR TREATMENT OF ORAL MUCOSITIS: CASE REPORT. ELISA KAUARK e BISPO, HAYANA FONTES, MAYARA SIMOES RAMOS LIMA, JULIANA BORGES DE LIMA DANTAS,
OOOO January 2020 MANOELA CARRERA MARTINEZ PEREIRA, ALENA RIBEIRO ALVES PEIXOTO MEDRADO and, GABRIELA MARTINS BOTELHO A 60-year-old male patient with a history of chronic drinking and smoking was diagnosed as having squamous cell carcinoma on the tongue beyond surgical therapeutic possibility. Radiotherapy and chemotherapy were indicated. After the fifth cycle of chemotherapy concomitant with radiotherapy, the patient reported pain in the oral cavity, which worsened after the use of methotrexate to treat peripheral neuropathy. The condition progressed to extensive oral ulcers requiring the use of a nasogastric tube for feeding. Low-intensity laser (AsGaAl, 680 nm, 2 J/cm2) was applied on the ulcers in a punctual and continuous manner. After 4 sessions, there was a significant improvement of the condition, with catheter removal and the patient being released from the hospital. The laser therapy proved to be effective in the treatment of oral mucositis lesions, reducing the pain and severity of the lesions, being a noninvasive and safe form of treatment.

As a therapeutic option, we performed photodynamic and low-level laser therapy in association with pharmacologic and local hygiene because of immunosuppression, obtaining remission of the lesions after 7 days. Laser therapy is a noninvasive, adjuvant tool that promotes analgesic, anti-inflammatory and biostimulating effects.
TREATMENT OF ORAL CHRONIC GRAFTVS-HOST DISEASE WITH CLOBETASOL: CASE REPORT. BARBARA BARRETO PACHECO VALENTIM, GABRIELA DE ASSIS RAMOS, e CAMILA BRANDAO LOBO, TAISA DOMINGUES BERNARDES SILVA and, HELITON SPINDOLA ANTUNES Graft-vs-host disease (GVHD) is the main complication of allogeneic hematopoietic stem cells transplantation. A 29-yearold Brazilian man was diagnosed as having severe aplastic anemia and submitted to allogeneic HSCT in October 2013. He developed systemic chronic GVHD, including the oral cavity (lichenoid lesions in right and left buccal mucosa and labial hyperchromia and was treated with mycophenolate mofetil, tacrolimus, cyclosporine, and dexamethasone solution [mouthwash]). Upon stabilization of chronic GVHD in the oral cavity, the patient displayed gingival atrophy and erythema (12-21/3342) on July 27, 2017. Dexamethasone mouthwash and tacrolimus ointment was unsuccessful. On November 11, 2017, the patient was instructed to use clobetasol gel 0.05% on individual tray 4 times/d/15 min. The total regression of gingival chronic GVHD was observed within 22 days. On January 1, 2018, the patient presented relapse of gingival erythema (12-21) with worsening of condition due to treatment discontinuation. We observed that clobetasol on individual tray was effective in this case.

Soft tissue changes in the oral cavity associated with leukemia such as oral bleeding, mucosal petechiae, mucosal ulceration, and infection are commonly described. Leukemic cells may infiltrate the oral cavity as leukemic infiltration to the gingival tissue but rarely involve other areas. The objective of this report is to describe a case of leukemic infiltration (myeloid sarcoma) in the oral cavity. A 48-year-old male patient was admitted to our service complaining of malaise, fever, and gingival bleeding. At clinical examination, beyond the gingival bleeding involvement, a rare clinical presentation characterized by the development of a persistent ulceration on the lateral border of the tongue was observed, which biopsy results showed the presence of infiltration of immature cells with scarce cytoplasm and hyperchromatic nucleus. Blood test revealed 119.000/mm3 leukocytes, whereas the myelogram demonstrated 87% of blasts carrying a myeloid differentiation confirmed by flow cytometry positivity confirming the diagnosis of acute myeloid leukemia.
