    Comedo carcinoma of the breast was found to be correctly diagnosed by US, based on the following ultrasonographic findings; 1) flat and irregular hypoechoic area and 2) fine echogenic spots, which reflect intraductal microcalcifications.

    Dermoid cyst o f ovary is seemed to be easily diagnosed by ultrasound because of it's characteristic echo-patterns.
    In the present study, ultrasonography was compared with rentgenographic and pathological findings in 107 patients with ovarian dermoid cyst undergoing surgical treatment.
    Mean age of patients was 37.5 (14-82) years old and 72% of them suffered from abdominal pain as caused by torsion of the tumor.
    In 86% of patients, the presence of hair ball or scattered hairs were demonstrated on ultrasonogram as a high-echoic solid part or echogenic linear feature respectively. Bony or dental component was revealed only in 42% on ultrasonogram, while they were demonstrated on X-ray finding in 79%, probably because they were frequently hidden behind the acoustic suad ows caused by fatty or hairy components.
    In summary, the dermoid cyst of ovary can be diagnosed by ultrasound for the presence of solid parts with smooth surface and homogeneous internal echoes and hair echoes.

    Early diagnosis of breast and thyroid cancers can be achieved by mass survey. Physical examination (PE) is usually used for mass survey of breast and thyroid, but it is affected by experience of examiner or by presence of non-palpable tumor. Effectiveness of ultrasonic examination (US) for breast and thyroid in Automated Multiphasic Health Testing Sysytem (AMHTS) in Tokai University Hospital have been appreciated in this tentative study in comparison with PE.
    12.6% of breast masses shown on US were not palpated on PE and were composed of cysts (80.4%) and solid masses (19.6%). About half of breast masses palpated by PE were not revealed by US except for fibrocystic pattern.
    22.6% of thyroid masses on US could not be palpated and consisted of diffuse goiter (9.3%) and local tumors (90.7%). All the thyroid masses on PE could also be shown on US.
    Pathological diagnosis of the cases for further examination was confirmed in few cases, and they will be also presented.
    In conclusion, breast and thyroid masses can be found by much more frequently than by PE, suggesting usefulness of US as one of modalities for mass survey of breast and thyroid, though difference of image quality of devices, frequency of transducers, acoustic couplers and so on are still to be improved.
