This paper presents the case of a 65 year-old woman suffering from recurrent oral aphthoid ulcers which rapidly evolved towards hyperplastic and ulcerated lesions over the entire floor of the mouth. The initial lesions were interpreted as non-specific aphthoid ulcers. Later, a tentative diagnosis of necrotising stomatitis with secondary reactive proliferating epithelial hyperplasia was made. The clinical symptoms and the immuno-phenotyping of lymphocytes circulating in the peripheral blood suggested the diagnosis of CD30-positive large cell anaplastic lymphoma. The biopsy showed only a pseudoepitheliomatous hyperplasia, reactive infiltrates and no lymphoma cells. The disease ran a fulminant course leading to death within 4 weeks due to acute gastro-intestinal bleeding. Autopsy revealed infiltrates of CD30+ large cell anaplastic lymphoma in a submandibular lymph node, in a thrombus stenosing the right subclavian vein, in the spleen, the anterior and posterior gastric wall as well as in the depth of the tumour on the floor of the mouth. The clinical and histopathological spectrum of CD30+ large cell anaplastic lymphoma is considerably variable. The particular feature of pseudoepitheliomatous hyperplasia has been reported especially in CD30+ anaplastic large cell lymphomas. An early correct diagnosis is rendered difficult in insufficient biopsy size, becauses this type of lymphoma often simulates other inflammatory or neoplastic skin diseases. Thus, with a necrotising and hyperplastic gingivostomatitis, the diagnosis of a CD30+ anaplastic large cell lymphoma should be considered.

The randomized international trial for childhood anaplastic large cell lymphoma, (ALCL99-R1) involving European study groups and a Japanese group, compared six courses of methotrexate 1 g/m(2) over 24 hours with an intrathecal injection (IT) (MTX1 arm) with six courses of methotrexate 3 g/m(2) over 3 hours without IT (MTX3 arm). In this report, data from the Japanese portion of the trial are compared with the results of the international study. Overall, 352 patients were recruited for the international study, and 44 of these patients were from Japan. Median follow-up times were 3.8 and 3.5 years, respectively, in the international and Japanese studies. The two-year event-free and 2-year overall survival rates of the international study were 74% and 93%. The corresponding figures for those registered in Japan were 81% and 96%, respectively. Clinical characteristics and outcomes of patients were similar in the two groups. Incidences of grade 4 hematologic toxicity, infection, and grade 3 to 4 stomatitis, which were reported to be statistically significantly higher after the MTX1 arm in the international study, were also statistically significantly higher after the MTX1 arm for those registered in Japan. Results of ALCL99-R1 treatment in Japan were essentially the same as in the international study. The international study is anticipated to contribute to establishing an optimal treatment for ALCL, a rare childhood lymphoma.
