Abstract
INTRODUCTION: Secretory carcinoma, previously known as mammary analog secretory carcinoma, is a rare malignancy of salivary glands. It has a diversity of microscopic patterns and is similar to other salivary gland tumors. CASE REPORT: This report presents the case of a 32-year-old female patient with a painless swelling of the upper lip and a history of recent surgery for an immature ovarian teratoma. The microscopic sections revealed a circumscribed neoplasm composed of macrocystic, papillary-cystic, and microcystic patterns with bland vesicular nuclei and vacuolated cytoplasm. Tumoral cells were strongly positive for mammaglobin, SOX10, GATA3, S-100, and vimentin. The diagnosis of salivary gland secretory carcinoma was made. After 22 months, there has been no recurrence. CONCLUSIONS: As secretory carcinoma is a relatively new entity, it is necessary to understand its characteristics. Although the overall incidence of second primary cancer in patients with salivary gland cancers is low, the possibility of its presence in such patients should be considered.
