Low Grade Basaloid Adenocarcinoma of Salivary Gland in Childhood — The so-called Hybrid Basal Cell Adenoma — Adenoid Cystic Carcinoma

Abstract

Two parotid gland tumors in young children are described. These tumors superficially resembled monomorphic adenomas but were unencapsulated and showed pushing invasion of parotid gland and adjacent adipose tissue. The patients remained well with no recurrence 8 and 13 years after surgical removal. Among 10 similar cases in the literature, 4 demonstrated local invasion or recurrence and 1 had nodal metastasis, but there were no tumor related deaths.
