Syndactyly is a common congenital anomaly of the extremities, and surgery is usually performed in childhood. Postoperative complications such as scarring and contracture are well recognized, but the development of adipocytic tumors at surgical sites has not been reported. We present two pediatric cases of adipocytic tumors arising after syndactyly release. Case 1 was a 1-year-old boy who developed a spindle cell lipoma 3 months after bilateral surgery. Case 2 was a 2-year-old boy with 5p deletion syndrome who developed lipomatous hyperplasia one year postoperatively. In both cases, skin closure was performed with absorbable multifilament polyglactin sutures. The lesions were completely excised, and no recurrence or deformity was observed during more than five years of follow-up. These cases suggest that surgical trauma, suture material, and possibly sex-related factors may contribute to postoperative adipocytic tumor formation. Awareness of this complication and long-term surveillance are recommended in syndactyly patients.
