title: Squamous inclusion cyst in a sentinel axillary lymph node associated with breast malignancy.
abstract: Axillary intranodal squamous inclusion cyst is a rare benign histological finding that may be confused with malignant diseases. A 52 years old female presented with a painless lump in the left breast for one and a half month. The mammogram was reported as being suspicious of carcinoma. Left breast lumpectomy and histology revealed infiltrating ductal carcinoma. After a month, modified radical mastectomy was done. Frozen section of axillary sentinel lymph nodes revealed benign histology with squamous inclusion cyst in one of the nodes. All lymph nodes recovered from mastectomy specimen were also benign.
