Abstract:
Subcutaneous form of neuromuscular hamartoma is extremely rare and histologically different from the conventional neuromuscular hamartoma of the peripheral nerve or benign Triton tumor by an indistinct nodular growth with ill-defined margin and marked collagen interposition. It is usually not associated with a major nerve. We report a case of subcutaneous neuromuscular hamartoma developed in the forehead of 24-year-old man. The tumor showed proliferation of dense, hyalinized fibrous tissue, in which single or group of mature skeletal muscle fibers and nerve fibers were haphazardly intermixed. Recognition of abnormally arranged muscle and nerve fibers is important not to miss this lesion.
