Cutaneous Granular Cell Tumor of the Breast: A Clinical Diagnostic Pitfall

چکیده
UNLABELLED We report the clinical-morphological study of a granular cell tumor in dermal/hypodermal junction and subcutaneous fat left breast of an 83-year-old woman with a family history of breast carcinoma. Mammography study showed a spiculated lesion in the lower inner quadrant with suspicion of malignancy. The results of fine needle puncture-aspiration were inconclusive. Subsequent tumorectomy revealed a poorly-defined indurated lesion of 1.1 x 0.7 cm. The histopathology study showed a proliferation of cells with ample and granular cytoplasm that were positive for S100, CD 68 and inhibin and negative for hormonal receptors. We present a benign lesion that clinically reproduces a breast carcinoma. KEYWORDS Granular cell tumor; Breast; Differential diagnosis; Cutaneous.
