Dysontogenic cyst of the tongue lined with heterotopic gastrointestinal mucosa

Abstract: A dysontogenetic cyst in the edge of the tongue in 1-year old boy was found lined with gastric, duodenal, and intestinal mucosa with its own lamina muscularis mucosae, with a thin layer of submucous connective tissue encircled by bundles of smooths muscle imprecisely separated from the striated lingual muscle.

The proportion of potassium and calcium in the vitreous body in relation to the time of death

Abstract: The method of atomic absorption spectrophotometry was employed to estimate the proportion of potassium and calcium in vitreous humour in 47 deceased persons The amount of both was found to increase in linear proportion to the time elapsed from death The correlation can be expressed in the form of equations The simultaneous estimation of the proportion of potassium and calcium in vitreous humour enables a more precise ascertainment of the time of death than the estimation of merely one of the two elements In persons who died of brain injuries, strangulation or who had suffered from conditions associated with metabolic breakdown, the time of death should not be determined according to the amount of calcium in vitreous humour; in such cases only the proportion of potassium should be exploited

Myxoma of the external nose

Abstract: A male bus-driver aged 45 had a proboscoid mass on the tip of his nose removed after three year's duration of the disease. Microscopically, the tumour appeared to be a myxoma with marked mucus accumulation extending subepidermally and leading to the formation of lacunes lined with fibroblasts.

[Morphogenesis of Mikulicz's cells (electron-optic study)].

Abstract: In a female aged 83 who had been living in Prague for years, a bioptic diagnosis of rhinoscleroma was made. The disease responded well to Septrin treatment. Electron microscopical examination confirmed the histiocytic origin of Mikulicz cells, but cast doubt upon the belief that the large phagocytic cysts in such cells developed by confluence of smaller vacuoles. The examination revealed that the large cystic formations only contained Klebsiellae and a dense finely granular material identical with that of the bacterial capsiles. The small vacuoles found in the vicinity of the large ones never contained bacteria and their contents was either coarsely granular of finely filamentous. Therefore it rather corresponded to degradation products of the original content of the larger phagocytic cysts. The final picture of the Mikulicz cell are macrophages with only small light rounded vacuoles containing mucoid but no Klebsiellae.

Acute pulmonary histoplasomis. 1st findings in Czechoslovakia

Abstract: A 57-year-old man, who for many years was treated for a pleomorphic lymphoma with cytotoxic drugs and x-ray therapy, died from the generalized tumor process. At autopsy, an extraordinary finding was found in form of acute pulmonary mycosts, which histologically appears to be histoplasmosis. Culture was not attempted, but the diagnosis is based on morphology, both of the organism proper and its intracellular location, and on results obtained by immunofluorescence studies. In numerous pulmonary vessels, endothelial pillows of histiocytes with yeast cells are found, typical for histoplasmosis, but no generalization was found in other organs. The source of the infection is not clear.
