In order to clarify the confused conception about so-called cenesthopathy, a pricise clinical and follow-up study was made on 22 patients who presented peculiar cenesthopathic complpints during long terms. Such cases as organic diseases, apparent schizophrenia and depression were excluded. The author could classify them into 5 groups. The 1st group is neurotic cases. The 2nd group is schizophrenic cases shifted from so-called borderline cases. The 3rd group is the cases of paranoid reaction. The 4th group is borderline cases in adolescence. The last 5th group is the cases unable to be classified into any groups above mentioned, and shows most characteristic symptoms. The distinguishing traits of 5th group were as follows. They developed symptoms in middle ages after being affected psychologically or physically. The persistent abnormal cenesthesia full of agony was rather tinged with hallucination, and it was some experience of moving, tense or pulling sensations, or of utterly new strange foreign sensations. Despite the peculiar strange complaints, they did not make pathological interpretations and their insight into their morbid states was preserved to some extent. But, pathological obsessive attitudes (such as skin-rubbing) and temporary abulic states often appeared, so that in their course they wore temporarily psychotic feature. Despite the chronic course, schizophrenic tendency did not appear. The author discussed the psychopathology of cenesthopathy and concluded that the 5th group should be diagnosed as typical cenesthopathia.
