Acne conglobata is a chronic inflammatory disease of the skin which is characterized by the presence of the constituents of acne vulgaris, such as comedones, papules and pustules, and in addition large elevated fluctuating plaques which are dusky blue and frequently form cutaneous or subcutaneous abscesses and oil cysts, which may perforate and form discharging sinuses, healing very slowly and often leaving keloidal or so-called bridge scars (Brückennarben) of Lang. The lesions closely resemble tuberculodermas of the colliquative type (scrofuloderma).

The clinical description and course of acne conglobata place the disease in close relationship to dermatitis papillaris capillitii (Kaposi) and to perifolliculitis capitis abscedens et suffodiens (Hoffmann).

If one wishes to classify this condition with the acnes and to draw an analogy, one might believe that acne conglobata stands in the same relationship to acne vulgaris that malignant syphilis does to an ordinary papular syphilid.
