RESUMO
Erythema multiforme is an acute mucocutaneous disorder, characterized by varying degrees of blistering and ulceration. We report a case of recurrent herpes-associated erythema multiforme managed with prophylactic acyclovir. An 11-year-old boy had lesions in the oral cavity and lips, which had been diagnosed as erythema multiforme minor. Four months later, the patient had desquamative gingivitis with erythematous lesions and necrotic areas in the skin. This episode was not related to drug intake, which suggests that the erythema multiforme was a result of herpetic infection. This hypothesis was supported by positive serology for herpes simplex virus. Five months later, the patient returned with new oral, skin and penis mucosal lesions. The diagnosis was confirmed as herpes simplex virus-associated erythema multiforme major. The episode was treated with acyclovir, and acyclovir was used prophylactically for 7 months to control the disease.

UNLABELLED: Granulocytic sarcoma (GS) is a localized infiltrate of immature granulocytes in an extramedullary site. This lesion is most frequently associated with leukemia, but can occur associated with other myeloproliferative disorders. GS can affect virtually any part of the body, but oral lesions are rare, with only 37 cases described. CASE DESCRIPTION: We present a case of GS in a 23-year-old female, with a prior history of acute myeloid leukemia, presenting with a solitary mandibular swelling in the region of the erupting lower left 3rd molar. After biopsy, conventional immunohistochemical stains were positive for CD45 (hematological marker) and myeloid markers, such as myeloperoxidase, and CD68, demonstrating a myeloid lineage with monocytic cell differentiation, suggesting the diagnosis of GS associated to AML-M5. CLINICAL IMPLICATION: Although GS is a rare tumor in the oral cavity, and its diagnosis is usually difficult, the clinician must know of its existence in order to make a differential diagnosis.
