What is Webbed penis and explain in detail?
Webbed penis also known as buried or concealed penis is an acquired or congenital condition in which the scrotal skin extends onto the ventral penile shaft. The penile shaft is buried in the scrotum or tethered to the scrotal midline by a fold or web of skin. The urethra and erectile bodies are usually normal. Webbed penis is usually asymptomatic, but the cosmetic appearance is often unacceptable. This condition may be corrected by surgical techniques.In the congenital form, the deformity represents an abnormality of the attachment between the penis and the scrotum; the penis, the urethra, and the remainder of the scrotum typically are normal.
Webbed penis may also be acquired (iatrogenic) after circumcision or other penile surgery, resulting from excessive removal of ventral penile skin; the penis can retract into the scrotum, resulting in secondary phimosis (trapped penis).

Signs and symptoms
Since the penis does not protrude when a man has this disorder, his ability to pass urine when he is standing or to participate in sexual intercourse will be impaired.
Visible signs may include but are not limited to:

Excessive skin and fat around the penis.
Tight, scarred preputial orifice.
Straining to urinate.

Cause
Webbed penis can be caused by various things such as:
Morbid obesity: which is known as excess fat around the genital area and abdomen, which makes the penis appear as though it is hidden.
Abnormalities that are there during birth – ligaments that attach the penis to underlying structures may be weaker than it is supposed to be.
Lymphedema: this is when swelling occurs around the scrotum area due to collection of lymph fluid, which may cause the penis to be buried inside tissue.
Acquired (iatrogenic) after circumcision or other penile surgery – resulting from excessive removal of ventral penile skin.

Mechanism and pathophysiology
Concealed penis is due to a lack of skin or an inelasticity of the penile skin and a weak penile skin fixation or excessive suprapubic fat, the penile webbed is characterized by a ventral fold of skin that connects the distal shaft and a penoscrotum, and a penis which is tucked away with the scar tissue that exists.
Concealed penis is an unusual circumcision complication. The excision of excess preputial skin occurs, although inadequate internal preputial epithelium is cut out. The new preputial orifice is thus distal to the gland and pushes the penile shaft into the supra-pubic fat at the level of mons pubis. In these cases, the released shaft includes a skin graft or local flaps. The other probability of this mechanism is that, since the penis continues to shrink into the mons pubis, the healed scarred pre-utile opening gradually becomes subcutaneously stuck. In such cases, the released shaft needs no skin graft or local flaps. For both mechanisms, the preputial skin is inadequately excised, causing the preputial holes to be distal from the pulse, trapping the pulp when the procedure is complete.In relation to lymphedema – When the lymph system operates normally, the lymph circulates through a series of vessels and ducts throughout the body. It then returns to the bloodstream with lymph. A blocking or failure in the genital area of this system may lead to a lymphatic leak into the soft tissues surrounding the system.
In relation to obesity – Obesity is a general cause of adult acquired buried penis. There are some parallels with buried penis seen in infants, frequently associated with poor skin suspension, abnormal excess fat accumulation in the pubic region, penis webbing, or penis trapping due to scarring post-circumcision. Similarly, adult buried penis is often associated with a laxity of connective tissue between the dart fascia and the penis, allowing the penis to tunnel more closely through the pre-pubic skin due to "hypermobility." This is exacerbated by obesity and weight gain as the phallus is covered by the suprapubic fat pad.

Diagnosis
Typically a physical examination may be used to diagnose a person with a buried penis. A doctor should be able to differentiate between buried penis and a tiny penis, known as micropenis.

Treatment
Adults with a buried penis either deal with or are subject to weight loss services. Weight loss programs are however sluggish and frequently do not "unbury" the penis; in addition, bad urine hygiene can lead to soft tissue infection.While the condition can resolve without intervention in young children, if infection is present, patients may ultimately need a definite reconstruction and urgent procedure
