A Case of Adenoid Cystic Carcinoma of the Breast Metastatic to the Scalp / 대한피부과학회지

ABSTRACT

Adenoid cystic carcinoma of the breast is a rare histologic type of breast cancer. Prognosis is favorable with rare recurrence or metastasis. We report a case of metastatic adenoid cystic carcinoma of the breast in a 50-year-old woman who presented with a 0.8 X 0.9 X 0.5 cm-sized dome shaped pink colored smooth surfaced partially eroded nodule on the scalp for 1 month. A skin biopsy revealed mainly solid malignant cell nests in the upper dermis, but in the lower dermis, tumor cell showed cylindromatous and adenoid pattern consistent with metastatic adenoid cystic carcinoma of the breast.
