A 1 year and 2-months-old neutered male cat underwent surgical resection of a cutaneous nodule on the midline of the forehead that had been present since approximately 6 months of age. Histopathologically, the nodule was composed of interlacing collagenous fibres interspersed with varying numbers of spindloid cells with round to oval nuclei and moderate to abundant amounts of pale eosinophilic cytoplasm. Similar to meningothelial cells, the spindloid cells were immunopositive for vimentin, neuron-specific enolase, E-cadherin and somatostatin receptor 2. Based on these findings and the absence of nuclear atypia and mitotic figures, the nodule was diagnosed as meningothelial hamartoma. Although cases of cutaneous meningioma have been reported, this is the first report of meningothelial hamartoma in a domestic animal.
