Concealed penis

　　1. Etiology

　　Concealed penis (concealed penis) is a congenital malformation caused by abnormal development of the tunica albuginea. It is different from the accumulation of fat at the base of the pubic bone and scrotum due to obesity, where the penis is deeply hidden under the skin. After the development matures and the fat tissue decreases, the penis can return to a normal state. Patients with concealed penis are due to abnormal development of the tunica albuginea of the penile area, where the loose and elastic tunica becomes a non-elastic, thick fibrous fascia, and sometimes even forms cord-like structures. These abnormally developed fascia and cords pull the penis towards the side, restricting it below the pubic symphysis.

　　2. Pathogenesis

　　Currently, there is no relevant information available.

　　If not treated in time, concealed penis can lead to difficulty in urination in children, and it is also prone to misdiagnosis. If not treated in time, it can develop into a sense of inferiority in boys during adolescence, and it may also cause pain during erection in adulthood, leading to sexual dysfunction, infertility, and other male diseases; some children may also have phimosis, causing psychological and physiological obstacles to the children.

　　The penis appears short and small. The prepuce opening is often narrow. The prepuce covers the penis like a bird's beak, not attached to the penile body. If the skin around the penis is pushed back with the hand, the normal penile body can be displayed. Most patients have phimosis, with very short skin covering the penis, but the inner prepuce plate is relatively abundant. If the concealed penis patient does not undergo penile release surgery, it may affect the development of the penis, causing psychological and physiological obstacles.

　　There is currently no effective preventive measure for this disease. Early detection and early diagnosis are the key to the prevention and treatment of the disease. It is related to the excessive intake of high-calorie fried foods or fast food among children today. The accumulation of a large amount of fatty tissue around the penis due to obesity pushes the prepuce forward, causing the separation of the penile body and the prepuce, and the penile body is buried in the fat to form a concealed penis. Therefore, it is necessary to eat less fried and fast food.

　　The penis is divided into three parts: root, body, and head, consisting of two corpora cavernosa on the dorsal side and one corpus spongiosum on the ventral side. The corpora cavernosa are rounded, blunt bodies with pointed ends. The two corpora cavernosa begin to fuse into one below the pubic symphysis. The corpus spongiosum is slender, rounded, and blunt, with its anterior end called the glans, which is shaped like a cap and covers the tips of the two corpora cavernosa. Corpus cavernosum angiography: X-ray films show that the penis foot and the inferior branch of the ischium are 'separated', and observe whether the penis venous system is visible. If the penis venous system is visible, the common types include penile dorsal vein leakage type, penile foot leakage type, corpora cavernosa septum leakage type, ectopic vein leakage type, corpora cavernosa type, and mixed type.

　　Diet should be light and nutritious. Eat more vegetables, fruits, milk, turtle, etc., which are rich in various amino acids, vitamins, proteins, and easily digestible tonics. Eat less greasy and heavy foods; eat less dog meat, lamb, and other warm-nourishing foods; eat less shellfish, bamboo shoots, taros, and other easily allergic 'inducing' foods; eat less drinks and snacks containing chemicals, preservatives, and additives. Avoid acidic, spicy, and salty刺激性 foods.

　　Treatment

　　There is a great controversy about the age of treatment and surgery for concealed penis. If the prepuce can be flipped up to expose the glans penis, surgery may not be necessary, and the concealed penis will gradually improve with age. The purpose of the surgery is to enlarge the prepuce opening and expose the glans penis. Attention should be paid not to perform a simple circumcision.
