The classification of the causes of eczema has not been changed in recent years and physicians are, for the lack of something more specific, forced to accept:

  1. External or exciting

  • Parasitic

  • Occupational

  • Irritation, excluding occupation

  • Internal (constitutional) or predisposing

With such a classification in mind, a series of 114 private cases of eczema (group A) was thoroughly studied in order to obtain any data bearing on the relationship of associated constitutional pathologic conditions and the presence of eczema in the same patient.Infantile eczema was excluded, and as far as possible the selections were made to exclude any eruption of which the external causative factor was known. In order to check the results, a similar study was carried out on 114 private patients (group B) who manifested dermatologie lesions other than eczema, and a comparison was made of the observations. This group (B) included the most commonly encountered skin diseases: acne vulgaris, 15 cases; psoriasis, 15 cases; impetigo contagiosa, 12 cases; dermophytosis, 21 cases; scabies, 13 cases; seborrheic eczema, 13 cases; urticaria, 13 cases and pityriasis rosea 12 cases.
