Sclerosing Variant of Adenoid Cystic Carcinoma - A Case Report on the Role of Sclerosis in the Prognostic Outcome

Sclerosing variant of adenoid cystic carcinoma (SACC) is a rare variant of adenoid cystic carcinoma (ACC) with only two cases in the literature. In this article, we report two cases of SACCs and attempt to explain the reason for sclerosis and its association with the disease outcome. The first patient is a 43-year-old Dravidian Indian female with a chief complaint of pain and swelling in the right posterior cheek region of four months’ duration. The second patient is an 8-year-old boy with a well-defined swelling in the left cheek region. Both these cases were diagnosed as sclerosing variants of ACC. The tumour was surgically excised for both patients. Both the patients had no signs of residual disease/recurrence. We opine that the dense sclerotic stroma may have a preventing role in tumour cell growth and progression.
