Case report of Basal cell adenocarcinoma of the parotid gland: clinicopathological and immunohistochemical study

The objective of this study is to identify the morphological and immunohistochemical characteristics that aid its diagnosis. A parotid tumor was resected in a 52-year-old patient; postoperative biopsy and immunostaining with Ki-67, CK19, p63 and α -smooth muscle actin were performed. The diagnosis was basal cell adenocarcinoma invading the tumor capsule, periglandular fat and lymph nodes. Immunolabeling with Ki-67, CK19, p63 and α -smooth muscle actin was positive. Subsequently, maxillary sinus metastasis was diagnosed. Given the morphological characteristics, elevated Ki-67 expression and metastasis, this is a malignant tumor, which differentiates it from the basal cell adenoma.
