In a group of 11,153 autopsied subjects a higher number of cholecystectomies was found in both sexes in individuals with large intestine tumors as compared with the rest of the autopsied persons without tumors (p less than 0.001). The results confirmed the hypothesis that cholecystectomy is a supporting factor in the process of carcinogenesis of the large intestine. We presume, in accordance to other studies, that the influence of cholecystectomy itself is not strong. For a development of a carcinoma, other carcinogenic factors must start or continue their effects. These factors are decisive for the genesis of a tumor.

Melanotic neuroectodermal neurocranial tumor of infancy of extra-intra-and subdural right temporal location: CT examination, surgical treatment, literature review.

A melanotic neuroectodermal neurocranial tumor of infancy of extra-intra-subdural right temporal location, examined by CT and successfully operated in a 33-month-old boy is reported in context with the literature. Out of 30 cases (including our case) of melanotic neuroectodermal neurocranial and intracranial tumors (MNNIT) 18 were located in the neurocranium (MNNT) and 12 intracranially, i.e. in the brain and cerebellum (MNIT). 23 tumors were located medially (11 at the anterior fontanel, one at the posterior fontanel, one in the 3rd ventricle, one in the sella turcica, one in the pineal region, 8 in the cerebellar vermis) and 7 laterally (five involved the temporal bone, one of which with intracranial propagation (our case), one in the temporal lobe of the brain, one in the skull posterior to the mastoid process). Twenty-eight cases were children (16 boys, 8 girls, four not stated), two adults. The location is important in respect to biology and surgery: MNNIT can be grouped as to its relation to the arachnoid barrier layer into malignant and benign. MNIT localised medially subarachnoidally are malignant. MNNT of small dimensions localised medially and laterally extraarachnoidally are benign. MNNT of extreme dimensions localised medially extra-intradurally are also benign, but difficult to treat. In the MNNT when diagnosed early and operated radically, the mortality can be lowered. Our case, presented on CT (1978) as first case of combined extra-intra-subdural location, represents the 173rd MNT and the 18th related to neurocranium.

Endovasal granulomatous lymphangiitis as a pathogenetic factor in cheilitis granulomatosa.

In 12 patients with cheilitis granulomatosa (ChG) epithelioid granulomas were histologically observed mostly within lympatic vessels. These granulomas appear to obstruct lymphatic lumina thus causing lymphostasis, lymphatic dilatation and lymphatic edema. The lack of literature concerning intraluminal localization of granulomas in cheilitis granulomatosa prompted the reporting of our observations.
