Gingival overgrowth as the initial paraneoplastic manifestation of Hodgkin's lymphoma in a child. A case report.

BACKGROUND: The purpose of this paper is to present the first case of gingival overgrowth, premature root resorption, and alveolar bone loss, which preceded the diagnosis of a stage IVB Hodgkin's lymphoma (HL) in a 9-year-old boy. METHODS: The child presented complaining of gingival pain which first appeared 3 months prior. Clinical examination revealed inflamed, hyperplastic gingivae, while x-ray showed premature root resorption and alveolar bone loss. Medical work-up was significant for cervical lymphadenopathy. Gingival biopsy, followed by lymph node resection, was performed twice. RESULTS: Histological examination of both gingival biopsies disclosed a mixed inflammatory infiltrate, while classical Hodgkin's lymphoma of the nodular sclerosis type was diagnosed from the second lymph node biopsy. Chemotherapy was instituted with mustard-vincristine-procarbazine-prednizone and adriamycine-bleomycine-vinblastine-dacarbazine. Remission of the lymphoma was observed with concomitant regression of the gingival overgrowth. CONCLUSIONS: The inflammatory gingival overgrowth, premature root resorption of deciduous teeth, and alveolar bone loss in this case, in conjunction with the regression of gingival overgrowth which followed the completion of chemotherapy, are strongly indicative of a paraneoplastic manifestation of HL. The postulated mechanism for the development of the manifestation is the constitutive activation of the transcription factor NF-kB. The gingival inflammatory reaction was probably further aggravated by the bacterial-stimulated cytokine secretion released by monocytes.

The oral manifestations of chronic graft-versus-host disease (cGVHD) in paediatric allogeneic bone marrow transplant recipients.

The oral manifestations of chronic graft-versus-host disease (cGVHD) in eight allogeneic bone marrow transplant (BMT) paediatric recipients were studied clinically, and lip biopsies were performed in seven of them. A prominent lichenoid reaction was observed in four patients, two with accompanying ulceration. Superficial mucoceles were present in three children. Clinically obvious xerostomia was seen in seven patients. Lip biopsies were positive and correlated with the clinical manifestations. Both clinical and histological findings confirmed the diagnosis of cGVHD. In three additional children, with systemic manifestations indicating cGVHD, the oral mucosa was clinically and histologically normal, and the systemic manifestations were, thus, attributed to drug reactions. The above findings indicate the high value of oral examination in diagnosing or confirming paediatric cGVHD. Superficial mucoceles, reported for the first time in paediatric recipients, seem to be important in the early diagnosis of cGVHD.

Effect of PI-HAART on the prevalence of oral lesions in HIV-1 infected patients. A Greek study.

OBJECTIVE: To investigate the association between the prevalence of oral lesions and highly active antiretroviral therapy (HAART) including a protease inhibitor (PI). DESIGN: Prospective study. PATIENTS AND METHODS: Ninety-five consecutive patients, attending an AIDS Unit, in Greece entered the study. Fourty-four patients were receiving PI- HAART, 14 patients were on double antiretroviral therapy, and 37 patients were not receiving antiretroviral therapy at the time of oral examination. Oral lesions were diagnosed by established presumptive clinical criteria. MAIN OUTCOME MEASURES: Oral lesions were scored. CD4 counts and viral load were determined and related to the prevalence of oral lesions. RESULTS: Oral lesions, and specifically oral candidiasis, were significantly reduced (P < 0.001) in patients receiving PI-HAART. Oral lesions were significantly increased in patients with CD4 counts <200 cells microl(-1) and viral load >20,000 copies ml(-1) (P < 0.001). The percentage of patients, with lesions on PI-HAART, and with CD4 < 200 and viral load >20,000 was 1.5 times lower (37.5%vs 58.8%, P < 0.001) than that of patients not receiving antiretroviral therapy, but with similar immune and viremic status. CONCLUSIONS: Oral lesions were significantly reduced in patients on PI-HAART. A direct anticandidal effect of PI was suggestive and seemed to have accounted, beyond the HAART-related immune reconstitution, for the reduction of candidiasis and all other oral lesions.

Oral pseudomembranous candidiasis, herpes simplex virus-1 infection, and oral mucositis in head and neck cancer patients receiving radiotherapy and granulocyte-macrophage colony-stimulating factor (GM-CSF) mouthwash.

Oral pseudomembranous candidiasis (OPC) was evaluated in 61 patients receiving head and neck radiotherapy (RT). Herpes simplex virus-1 (HSV-1) reactivation was also investigated in 14 patients. According to the agreed protocol, granulocyte-macrophage colony-stimulating factor (GM-CSF) mouthwash was administered in 46 patients with radiation-induced ulcers. Candidiasis was diagnosed in 31 patients. Candida albicans was the most frequent isolate. Multiple Candida species were isolated from the lesions of four patients. Concurrent candidiasis and radiation-induced ulcers were observed in 17 patients. Viral culture and the polymerase chain reaction disclosed the presence of HSV-1 in five patients. Twenty of the 46 patients, with initial mucositis grade II and grade III, completed RT with mucositis grade I, indicating a beneficial effect of GMCSF mouthwash, although further controlled studies are necessary to verify that. In conclusion, OPC was an important infection in patients undergoing radiotherapy. The role of HSV-1 in oral mucositis during head and neck radiotherapy needs additional study.
