Adenolymphoma

ADENOLYPHOMA, a tumor in which there is a combination of proliferations of epithelial (glandular) elements and lymphoid tissue. These proliferations are benign and occur either through improper development of adjacent organs (for example, inclusions of epithelial complexes of the submandibular or parotid gland in the lymph nodes of the neck), or through "pseudometaplasia" of the endothelium of the sinuses of lymph nodes, which, transforming into tall cylindrical cells, simulates glandular ducts, or through benign metastases of epithelium in lymph nodes, especially during chronic ulcerative processes in the corresponding organs (e.g., in the intestine, uterus). Only in a small number of cases does A. belong to the category of tumors (e.g., branchiogenic papillary cysto

adenolymphomas of the neck and parotid gland), although even here there is initially an element of improper development. A. presents practical and theoretical interest in that to a certain extent they illuminate the question of the origin of rare forms of primary cancers of the lymphatic nodes.
