Inclusion body fibromatosis is a rare benign soft tissue neoplasm typically involving fingers and toes of children in mostly less than one year old. Histologic findings include spindle-shaped fibroblasts surrounded by dense stroma and small perinuclear eosinophilic inclusions in the cytoplasm. Although the tumor typically undergoes spontaneous regression, surgery is considered when functional impairment or deformity develops with the lesion. Unfortunately, recurrence rate was reported to be as high as 60 % following tumor excision. Authors would like to present our case where the tumor occurred in relatively older child and kissing lesion was found a few months after the surgery.
