The sections show a multiloculated cyst with thin walls containing bland lymphoid cells and unremarkable paucicellular fibrotic tissue. The lymphoid component has germinal centre formation. The cyst lining is predominantly a simple thin epithelium. Minimal cytoplasm is present in the cyst lining. Focally, the epithelium is multilayered; however, pseudo-bilayering is absent. No significant atypia is present. Proliferative activity is not apparent. | |||
