Lymphangioma of Bladder

Abstract

We report the first case of a lymphangioma arising from the wall of the bladder, protruding into the lumen on 1 side and invading the peritoneal cavity on the other side. The presenting sign was painless macroscopic hematuria that had occurred initially 2 months before hospitalization. Treatment consisted of partial cystectomy. A review of the literature failed to reveal a report of an identical case.

First Case of Lymphangioma of the Bladder in an Adult

“…5 ! 2 cm in size proFirst Case of Lymphangioma of the Bladder in an Adult truding into the bladder was found and treated with partial cystectomy [1]. In our case, the patient only showed irritative voiding symptoms.…”

“…Neck and axillary lesions are the most common manifestations. Lymphangioma of the urinary tract is extremely rare and to our knowledge only 1 case of lymphangioma in the bladder of a child has been reported [1]. We report the first case in an adult and review the literature.…”

“…Reported cases occurred in the urethra and bladder of a pediatric patient [1,2]. In contrast, about 40 cases have been described in the kidney [3].…”

Lymphangioma of the Urethra

“…The first was in a 23-month-old boy, associated with hemangioma of the bladder and external genitalia [14], The second was in a 13-year-old boy, with no other find ings [15], Both presented with hematuria and partial cys tectomy was done in both cases.…”

“…Two cases of anterior urethral polyps in children have been described [6] and about 20 cases of urethral heman gioma have also been reported [7], A lymphangioma is often congenital and presumably arises from sequestration of primitive lymphatic anlagen and malformation of lymphatics. The resulting lymphan gioma becomes isolated from normal lymph vessels [8][9][10][11][12][13][14][15], Whether the lymphangioma is a true neoplasm or hamartoma is controversial [8,9], Classification of lym phangiomas in various books is confusing but there are three main types: (1) capillary, presenting as diffuse or nodular growth of cheek, lip, tongue, skin or subcutaneous tissue, (2) cavernous, found in skin and mucous mem branes and (3) cystic, often described as cystic hygroma, found in neck, axilla, groin [12,15],…”
