Lymphangiomas are benign tumours of the lymphatic system, and there are several reported cases of scrotal lymphangioma in the literature to date. We report a rare case of multilocular cutaneous lymphangiomatosis treated with surgical excision (total scrotectomy and reconstruction using split-thickness skin grafts with vacuum-assisted closure dressing).
Case reportA 39-year-old healthy male presented with a 20-year history of recurrent, complicated scrotal lymphangiomatosis. The lesions had previously been treated with local excision and cauterization, laser ablation and cryotherapy, but the lymphangiomas recurred quicker and denser in number following each treatment. The patient was referred to our urology clinic in 2007 with complaints of perineal pain. Physical examination demonstrated the scrotum itself was nodular and thickened with innumerable cutaneous lymphangiomas, with complete sparing of the penile skin. Following discussion with the patient, a continued conservative approach was initially exercised with antibiotic treatment and suppression of chronic scrotal cellulitis without surgical consideration of the lesions themselves. Despite this, the patient continued to suffer from recurrent infections of spontaneously ruptured lesions. Given the ineffectiveness of conservative therapy, the notable confinement of lymphangiomas to the scrotal skin ( Fig. 1), and the ongoing psychological impact of the condition on the patient, a decision was made to escalate to surgical management consisting of total scrotectomy with reconstruction.The patient was brought to the operating room, and following induction of general anesthesia, a "W" incision was made along the baseline such that the entire scrotum was incorporated while leaving skin 1 cm above the anus intact, thus forming a shape resembling the letter "W" (Fig. 2). The scrotum, including the epithelium, dermis, and superficial subcutaneous tissues, were dissected off using a combination of #15 blade and the Metzenbaum scissors (Fig. 2). While the scrotectomy was being performed, the split-thickness graft was harvested from a shaved area on the right donor thigh. The Zimmer dermatome (Zimmer Inc., United Kingdom) set to 12/1000 of an inch was used to harvest the skin graft, which was then meshed in a 1.5:1 fashion, and used to cover the area of defect. The borders of the graft were stapled in place, and then further quilted into place using 4-0 Vicryl sutures (Fig. 3). A vacuum-assisted closure (VAC) sponge was conformed to the skin-grafted area and reinforced with additional OpSite (Smith & Nephew Healthcare, United Kingdom) dressings.At one-month follow-up, there were a few small areas of delayed healing, overall good take of the graft, and no recurrence of scrotal lymphangiomatosis (Fig. 4). The shaft of the penis appeared to remain well-vascularized. The patient reported little pain, and was able to have normal erections with no chordee or deviation. The six-month follow-up showed almost complete healing, and no recurrence was observed (Fig. 5).
