Abstract
Roentogenographic studies of soft tissue have rarely been made in the field of dermatology in Japan. Soft tissue X-ray photographing technique was applied to cutis lines and other soft tissue of subjects with skin diseases (particularly small tumors, nodules and so on) and of those with a healthy skin (controls).
It was found that a normal skin proved to have an even-shadowed uppermost surface layer of no structure, this being cutis line, while subjects with an abnormal skin revealed many abnormal shadows in cutis line as well as in other soft tissue.
In order to study the abnormalities, a series of cases observed was classified into following groups, namely neoplasma, inflammatory diseases and non-inflammatory diseases. It was found that images varied depending on the degree of the abnormality and it was concluded that soft tissue roentgenography is a useful tool and aid in the diagnosis of skin diseases.
