Summary. Two cases of calcinosis localis are described and the literature on this subject is discussed. Case I. A male, 59 years of age. For many years his right knee had been stiff, following a resection for tuberculosis (?). Twice the right crus has been subject to traumata, four years and twelve months ago respectively. For the last two years some strange ulcers have been present on the right crus, corresponding to which a cal­ cinosis localis was demonstrated. On account of the formation of an abscess on the crus, an ampu­ tation was made of the right femur. The surgeon considered the diagnosis of a “ forgotten” gravitation abcsess form the old tubercu­ losis (?) of the knee the most likely, but this opinion was definitely rejected by the x-ray and histological findings. Histological examination revealed not only calcification of the interstitial connective tissue, but also fairly extensive calcifications of the small vessels, as well as local changes in the bone. In the de­ posits on the interosseous membrane of the crus metaplastic bone formation was demonstrated, but not in the other deposits. Case II. A typical case of calcinosis circumscripta localized to the right forefinger. X-ray treatment was attempted, but it was not of any effect. According to the family history it seems that the mother of the patient has suffered from the same disease, which might indicate a hereditary disposition. The value of Debye-Scherer diagrams in future examinations of calcinous deposits is pointed out.
