ABSTRACT
Myxomas are benign neoplasms of uncertain origin and etiology. First described by Virchow in 1863, they are derived from primitive mesenchymal structures and feature components of the umbilical cord. More recently, in 1995, Takahashi et al., through extensive research confirmed the fibroblastic and histiocytic origin of the tumor. We present a case in a female infant whose outcome and follow-up are discussed as well as a literature review in order to discuss many features of this rare pathology.

Polymorphous low-grade adenocarcinoma (PLGA) is a malignant neoplasm of low aggressiveness that occurs almost exclusively in the minor salivary glands, primarily those in the palate. We report a case of PLGA that arose in the base of the tongue and subsequently metastasized to the neck. The tumor was resected through the oral cavity with wide margins and dissection. The neck metastasis was treated with radical neck dissection and radiotherapy. The patient recovered and remained disease-free at follow-up 30 months later. This case shows that PLGA, which has a variable morphologic appearance, can occur at sites other than the salivary glands.
