Two neck tumours in young children with similar clinical features were compared using light and electron microscopy. Both tumours consisted of uniform sheets of epithelial-like cells and there were scattered stromal elements in one. Tonofilaments in sheets or bundles reminiscent of squamous epithelium were striking in the epithelial cells. Intercellular junctions were frequent but true desmosomes were not seen. Most cells contained a few secretory droplets. Occasional secretory cells, foam cells and cilia were observed. Since these tumours were not sited superficially they are unlikely to have been derived from skin epithelium. An origin in branchial sinus remnants capable of differentiation towards squamous and ciliated epithelia is suggested.
