Granular cell tumor (GHT) is a rare soft tissue tumor. It can often be seen in the upper limb, but it can be seen anywhere in the body. The majority of tumor cases are self-sufficient and about 2% are malignant. The tumor is observed in the breast by 5-8%. It appears with slowly growing, painless, mobile masses. The exact diagnosis is histopathological. The treatment is extensive. Seventy-five-year-old woman, who was sick in the right axil, applied to the mouths with an exhausted mass. Eight months ago the result of mammography in the right breast was BIRADS 3 by general surgery for the mass was made mastectomy and acne disection. Breast pathology was identified as filloides tumor. Five of the thirty lymph nodes in the axile were found to GHT. A biopsy was performed in the insecticus. In histopathological measurements, S-100 and CD-68 positivity were observed in the tumor cells with eozinofyl coloring and clear nucleolusua of pleomorphic nucleus. The tumor was removed with a wide excision and the defect area was partially closed with a skin greft in the thickness. In pathological measurements, the GHT in the axil was determined to be malignant GHT from the skin, not as a breast metastasis. The Ki-67 proliferation index was 10%. The surgical limits were seen as healthy. No complications were observed in the postoperative follow-up of the patient. GHTs in the axil are generally seen as a result of breast metastasis and the vast majority of them are selfish. Malign skin GHT is a rare phenomenon.
