Abstract

Neurilemoma of the tongue is very rare, solitary benign slowly growing neoplasm. We have recently experienced 2 cases of neurilemoma of the tongue which occurred in 20 year old female and 22 year old male. They complained of a painless mass on the left side of the tongue base and on the right anterior margin of the tongue respectively. Grossly the tongue mass of the first case measured 1×0.8×0.5㎝ in dimension. The cut surface was homogeneous gray white in color with no necrosis and hemorrhage. Microscopically, this tumor was composed of spindle cells with long ovoid nuclei. The nuclei were arranged in palisades that were separated by fibrillar cytoplasmic processes. There were also noted Verocay boidies. Grossly, the submitted tumor mass of the second case was consisted of three fragments which were divided by surgeon, averaging 0.7×0.5×0.5㎝ in dimension. The cut surface was homogeneous gray white in color with firm-consistency. Microscopically the neoplasm was made up to spindle cells with ovoid nuclei. A few rows of palisading nuclei enclosed spaces filled with ribbed collagen, forming Verocay bodies.
