YOSHIHIRO ABIKO TAKASHI MURAMATSU YOUICHI TANAKA TOMOYUKI OHUCHI MASAAKI SATOH KAZUHIKO OKUMURA TOSHIYUKI SHIBATA TAKASHI LNOUE MASAAKI KANAZAWA MAKOTO ARISUE MASAKI SHIMONO TOHRU KAKU 《Pathology international》1998,48(6):460-466
Two cases of basalold-squamous cell carcinoma (BSC) of the oral mucosa are described. The first case occurred at the floor of the mouth in a 58-year-old man, and the second case occurred at the mandibular gingiva in a 79-year-old woman. The laboratory data of the first case showed a positive response to hepatitis C virus antibody. in the first case, the tumor mass measured 4 times 4 cm in size, and was i-texl at the lingual side of the median mandible beside the sublingual gland. In the second case, the tumor mass measured 25 times 15 mm In size, and was located in the alveolar mucosa of the right mandible. Histologically, both tumors showed a neoplastic epithelium arranged in a solid pattern with evidence of peripheral palisading, central necrosis, and some squamous differentiation. The pro-ilferathfe activities of the BSC were compared with conventional squamous cell carcinomas (SCC) in the oral floor and gingiva, respectively, by employing a sensitive argy-rophillc nuclear organizer region (AgNOR) staining method. The number of AgNOR per nucleus of the BSC was higher than that of any other SCC cases. The results support the opinion that BSC of the oral mucosa has a worse prognosis than conventional SCC. 相似文献

Urinary concentrations of pregnanetriol-3-glucuronide (PT-3-G) were determined in 485 normal Japanese subjects (277 males and 208 females), aged 5 days to 20 years, using an enzyme-linked immunosorbent assay (ELISA). The usefulness of urinary PT-3-G concentrations before giving the morning dose of medications in monitoring the adequacy of glucocorticoid treatment was assessed in eight patients with 21-hydroxylase deficiency (21-OHD). The ratio of PT-3-G to excreted creatinine (PT-3-G/Cre ratio) increased significantly during the first month and did not change from age 1 month to 1 year of life. The ratio decreased to a nadir at age 3 or 4 years followed by continuous, significant increase until late adolescence. In the subjects treated with corticosteroids for 21-OHD, PT-3-G/Cre ratios at the 50th percentile or below suggested a risk of excessive treatment, as judged by the patients' growth. Measurement of the PT-3-G/Cre ratio enabled recognition of corticosteroid overtreatment, which was not demonstrated by determining the serum concentrations of 17α-hydroxyprogesterone (17-OHP) On the other hand, ratios at the upper 95–99% tolerance limits seemed to be required for optimal control. The present study revealed the normal age-related changes in urinary excretion of PT-3-G and showed it to be a reliable marker for evaluating glucocorticoid treatment in young children with 21-OHD. 相似文献
