Gingival Anaplastic Large-Cell Lymphoma Mimicking Hyperplastic Benignancy as the First Clinical Manifestation of AIDS: A Case Report and Review of the Literature.

This paper presents an unusual case of gingival ALCL, which mimicked a benign hyperplastic lesion that occurred in a 57-year-old white man representing the first clinical manifestation of acquired immunodeficiency syndrome (AIDS). The patient was referred to the Dental Clinic of PUCPR complaining of a lobulated nodule on the gingiva of his upper central incisors. The presence of advanced chronic periodontitis and dental plaque raised suspicion for a benignancy. An excisional biopsy was performed, and large pleomorphic cells with an abundant cytoplasm, sometimes containing prominent nucleoli and "Hallmark" cells, were observed through hematoxylin and eosin staining. The tumor cells showed strong CD30 expression, EMA, Ki-67, and LCA, and negative stain for p80(NPM/ALK), CKAE1/AE3, CD20, CD3, CD56, and CD15. The final diagnosis was ALCL (ALK-negative). Further laboratory tests revealed positivity for human immunodeficiency virus (HIV). The patient was submitted to chemotherapy, but four months after diagnosis, the patient died due to pneumonia and respiratory failure. Oral anaplastic large-cell lymphoma (ALCL) is a rare disorder. Only 5 cases involving the gingiva have been reported, and to our knowledge, this is the first case reported of the ALCL, which mimicked a hyperplastic benignancy as the first clinical manifestation of AIDS.

Carcinoma Mucoepidermoide Juvenil: Relato de Caso e Revisão da Literatura / Juvenile mucoepidermoid carcinoma: a case report and literature review

O Carcinoma mucoepidermoide juvenil é uma doença rara, que ocorre mais frequentemente nas glândulas menores do palato duro. Os pacientes, em geral, referem edema progressivo e indolor. O tratamento de escolha é a ressecção cirúrgica, estando a radioterapia indicada no pós-operatório, em casos de presença de fatores de mau prognóstico. Relatamos o caso de uma paciente de 12 anos de idade com carcinoma mucoepidermoide juvenil em palato duro com radioterapia adjuvante.

Juvenile mucoepidermoid carcinoma is a rare disease that occurs most often in the minor glands of the hard palate. Patients usually report a progressive, painless swelling. The treatment of choice is surgical resection, with radiotherapy given postoperatively when poor prognostic factors are present. We report the case of a 12-year-old female with mucoepidermoid carcinoma of the hard palate with adjuvant radiotherapy.
