RESUMEN
BACKGROUND: Seroma formation is a frequent complication following radical lymph node dissection (RLND) in patients with metastatic melanoma. Several strategies have been used to prevent fluid accumulation and thereby reduce the duration of postoperative drainage, including fibrin sealants. METHODS: This was a prospective, single-center study in which consecutive patients undergoing surgical treatment of stage III metastatic melanoma by axillary or ilio-inguinal RLND were randomized to receive standard treatment plus fibrinogen/thrombin-coated collagen sealant patch (CSP) or standard treatment alone. The primary endpoint of the study was postoperative duration of drainage. RESULTS: A total of 70 patients underwent axillary (n = 47) or ilio-inguinal (n = 23) RLND and received CSP plus standard treatment (n = 37) or standard treatment alone (n = 33). Mean duration of drainage was significantly reduced in the CSP group compared with standard treatment (ITT analysis: 20.1 ± 5.1 versus 23.3 ± 5.1 days; p = 0.010). The percentage of patients drainage-free on day 21 was significantly higher in the CSP group compared with the standard treatment group (86% versus 67%; p = 0.049). CONCLUSIONS: Use of the tissue sealant resulted in a significant reduction in duration of drainage. Further studies are warranted to confirm these results in different and selected types of lymphadenectomy.

In this paper a case of vast desmoid tumor of the abdominal wall associated with familial adenomatous polyposis is reported. Desmoid tumors represent a particular type of fibrous neoplasms with a higher prevalence in females. They are extremely rare in the sporadic form, while they are found in about 10% of patients affected by familial adenomatous polyposis. Despite their benign histology and the absence of metastatic potential, they can be considered as fibrosarcomas with a low level of malignancy because of their locally invasive nature. The treatment of choice is surgical excision, as wide as possible, aimed at preventing recurrences, which are frequent in this tumor type. The usefulness of complementary therapies such as radiotherapy, hormone or chemotherapy, is not entirely clear.
