Unusual presentation of epidermoid cyst mimicking breast cancer involving the areola-Case report.

ABSTRACT

INTRODUCTION: Epidermoid cyst is very common benign lesion of the skin. And may appear anywhere on the surface of the body. Diagnosis is made in most cases by clinical examination, but histological evaluation may be needed in unusual cases. PRESENTATION OF CASE We report a rare case of a 44 year-old woman who presented with a rapidly growing inflamed mass localized to the left areola, which grew to 4 cm in diameter within a few months. The diagnosis of malignancy was ruled out following pathology examination consistent with epidermoid cyst. After a course of antibiotics, she underwent surgery with nipple sparing and reconstruction of the areola. DISCUSSION: Preoperative diagnosis based on biopsy enable limited surgical excision and preservation of the nipple. Reconstruction of the areola by local areolar flap enable good aesthetic result. CONCLUSION: It is important to be aware of this entity of epidermoid cyst mimicking breast cancer, and the treatment options available in these cases.
