Purpose: Lipoblastoma is a rare, benign, adipose tissue tumor. We report the largest single institution experience managing these uncommon neoplasms. Methods: We retrospectively reviewed 32 cases of lipoblastoma entered in the pathology database at our institution between January 1991 and August 2005. We conducted a comprehensive literature review of lipoblastoma and summarized the results of the largest series published. Results: Most patients presented with an enlarging, palpable, firm, nontender, mobile mass. The male-to-female ratio was 1.9:1. The anatomical distribution was trunk (n = 12), extremity (n = 12), groin (n = 5), and neck (n = 3). Average age at resection was 2.8 years (range, 2.6 months to 12 years). Thirty-one cases were completely excised, although 1 patient underwent staged partial excision to preserve nerve function. Chromosomal analysis performed in selected patients revealed characteristic aberrations in chromosome 8. Complications included keloid formation (n = 3), wound infection/dehiscence (n = 2), wound seroma (n = 1), and transient brachial plexus neurapraxia (n = 1). Average follow-up was 7.4 months (range, 1 day to 6.5 years); 2 patients were lost to follow-up. There were no recurrences. Conclusions: A staged approach with meticulous sparing of the neurovascular bundle provides excellent functional outcome for patients with large tumors. Nonmutilating surgical excision is the treatment of choice.
