The term balanitis xerotica obliterans is usually used as a synonym for kraurosis penis to describe a chronic inflammatory process of the scleroatrophic type that affects, singularly or together, the glans, prepuce, and urethral meatus. This disorder was first described by Stühmer" as a genital disease arising in patients who underwent an operation for congenital phimosis. Actually, most authors" º" 9"| 7 consider balanitis xerotica obliterans the location in the male genitalia of lichen sclerosus et atrophicus. Balanitis xerotica obliterans is usually found in patients between 30 and 60 years of age; only occasionally has it been observed in the prepubescent""""""" or in the aged.” In most cases it arises spontaneously; nevertheless, many authors have observed the disease arising after an accidental trauma or surgery for phimosis or other diseases of the prepuce."""""" The initial symptoms of this disease are itching or burning and erythematous spots localized on the prepuce or on the glans skin. The end of the preputial sac and its inner surface are initially edematous and flushed; then they become in-creasingly thicker and harder and their complex-ion becomes white-ivory as a result of sclerosis. The skin of the penis shaft is rarely affected. In uncircumcised patients, progressive sclerosis causes a hard and contracting fibrous ring (Fig. l), with possible erosions and fissures, localized on the apex of the foreskin or 1–1.5 cm below it (Fig. 2).
