초록/요약
Granular cell tumors (GCT) are found in virtually any body site, including the tongue, skin, subcutaneous tissue, breast, rectum and vulva. However, they are rarely seen in the abdominal wall. We report here on a rare case of GCT in the rectus muscle of the abdominal wall. A 44-year-old woman presented with a non-tender, hard mass in the right lower abdominal wall. Upon microscopic examination, the tumor was found to comprise of large polygonal cells with an abundant eosinophilic granular cytoplasm and round to oval nuclei. Upon immunohistochemical staining, the large cells showed S-100 and CD68 positive granular aggregates in the cytoplasm. Many lysosomes of variable size were observed in the cytoplasm.
