[The clinical picture, classification and surgical treatment of paraffinomas of the external genitalia].

Basing on operative data on 42 patients and literature data, the authors hold that clinical presentation of external genitalia paraffinomas varies depending on the quantity of the introduced emulsion, its chemical structure, site and depth of the injection, duration of the suspension stay in the tissues. Paraffinoma dissection within intact tissue is thought the only and radical treatment. The technique should be based on adequate classification of the disease taking into consideration clinical varieties, localization and extent of the process, involvement of the adjacent tissues, complications. Four forms of the disease are recognized: foreskin, stem, penile-scrotal, penile-pubic-scrotal. Etiological factors, spread of the disease, kind of complication are considered also. The classification permits unification of surgery, reliable comparison of the results from various institutions. In preputial complicated disease a simple policy is employed--circular dissection of the foreskin. Radical dissection of the affected skin with subcutaneous fat and plastic repair of the defect with a scrotal skin double-end graft according to Reich's technique in modification of the authors or replacement of the wound-adjacent triangle grafts according to A. A. Limberg. Utilization of this approach led to substantial improvement of end results in the treatment of 39 patients.
