[Lung metastases--limitations and possibilities of radiologic diagnosis]

The different sensitivities of chest radiograph, full-lung tomography and computed tomography (CT) are determining factors in the diagnosis of pulmonary metastases. Pathogenesis and pathologic-anatomical morphology explain the radiological findings. Knowledge of spontaneous or therapy-induced changes and "sterilized" metastases is important for follow-up studies. The precise densitometry in CT improves the assessment of degree of a pulmonary disk-shaped lesion. Histological diagnosis may be obtained by fluoroscopically guided percutaneous thin-needle biopsy.

Bilateral diffuse benign melanocytic tumours of the uveal tract. A clinicopathological study

In a patient treated for gall-bladder carcinoma bilateral choroidal tumours were clinically interpreted as intraocular metastases. Post mortem histological examination of both eyes revealed a bilateral diffuse benign melanocytic tumour of the uveal tract. The association of bilateral uveal naevi with terminal carcinomas has been reported in seven other cases; it may be a new ophthalmological syndrome.

The origin of the pseudoglandular spaces in metastatic smooth muscle neoplasm of uterine origin. Report of a case with ultrastructure and review of previous cases studied by electron microscopy

The entity known as "leiomyomatous hamartoma," a term that has been used in reference to metastatic smooth muscle neoplasms of uterine origin (MSMNUO), is uncommon. Several articles have dealt with clinical and light microscopic aspects of this lesion. Four reports on the ultrastructure of this type of neoplasm have been published, but they have been primarily concerned with its smooth muscle component. Much controversy exists as to whether the glandular elements are part of the neoplastic process or preexisting pulmonary elements. This ultrastructural study confirms that the gland-like spaces represent entrapped alveoli and terminal respiratory bronchioles.
