[Omphalolith].

In rare instances a hard, smooth, almost black bolus, "omphalolith" is found in the umbilicus, resembling a malignant melanoma. After removal by a pincette it reveals on its backside a colourless lamellar epithelium. At microscopic examination it also constists of stratified corneocytes. Differential diagnosis of the omphalic stone includes the so called umbilical cholesteatoma, an accumulation of crumbling, fetid masses in the umbilicus, often times accompanied by seborrhea which may lead to abscess formation. The term omphalic stone could not be found in the medical literature. However, it has been used to name a jewel which is worn in the umbilicus or a huge stone in Delphi which was believed by our ancestors to be the center of the world.

[Tuberculosis of the peripheral lymph nodes].

In Germans as well as in "foreign workers" acute tuberculous lymphnode disease is most often seen in the drainage areas of old sometimes even calcified tuberculous processes. The infective agent is almost always mycobacterium tuberculosis. Resistant strains are rarely found even in recurrent disease. Differential diagnosis includes tulareaemia, cat scratch syndrome, lues, and foreign body reaction. In those cases in which the histopathologic findings are similar to productive tuberculosis, sarcoidosis and epitheloid cell reaction in the drainage area of malignant tumors have to be taken into account. Knowing the usual good-response to tuberculostatic drugs there is no need to perform risky operations or to utilize rather dangerous agents such as streptomycine.

[Clinial picture and localization of skin metastasis of visceral carcinomas].

Seven cases with secondary skin carcinomas are described. The primary tumor was located at the tongue, the larynx, the thyroid, the abdomen, the ovaries, the collum uteri and the rectum. From the literature 60 other patients with secundary skin carcinomas and 100 primary carcinomas were evaluated. Clinical evidences for a secundary skin carcinoma are: unusual localization, multiple occurrence and an even surface. It was examined whether the localization of the secundary skin tumor refers to the localization of the primary tumor.

[Treatment of malignant melanoma with dinitrochlorobenzene ointment].

35 patients with malignant melanomas in different stages were treated with dinitrochlorobenzene according to Malek-Mansour in the last three years. Nine typical cases are demonstrated. The treatment is more effective when the tumor lies close to skin surface and has not yet spread. Distant metastases may react--but normally these metastases cannot be removed. Regarding effects and side effects of DNCB, the methods of treatment and the range of indications are described.
