To discuss the clinical and pathological features, differential diagnosis and prognosis of fibrous hamartoma of infancy (FHI), seventeen FHI specimens were analyzed with H&E staining and strepavidin peroxidase (SP) immunohistochemistry to detect distinguishing tissue markers. The long-term outcomes of select cases were also obtained. Among the 17 patients (13 males, 4 females, average age 16 months), FHI manifested as a subcutaneous painless mass, primarily on the back of the neck, the upper arms and buttocks. One recurrence was noted among six follow-up cases. The tumors consisted of three main components: fibrous connective tissue; mature fat; and undifferentiated mesenchymal tissue. Immunohistochemistry revealed that fibrous connective tissue was positive for SMA and actin, mature fat tissue was positive for S-100 protein, and undifferentiated mesenchymal tissue was positive for CD34 and was partially positive for actin and SMA. The tumors were negative for desmin, NSE, bcl-2, ?-catenin and Ki-67. In brief, FHI is a benign, fibroblastic/myofibroblastic proliferative lesion. Defined histologic features of FHI as presented here would distinguish FHI from similar invasive tumors including infant fibromatosis, calcifying aponeurotic fibroma, fibrous fatty tumor and embryonal rhabdomyosarcoma. Once clearly identified, FHI is curable with complete resection.
