Abstract

Ten cutaneous masses from Djungarina hamsters (Phodopus sungorus) were diagnosed as nine atypical fibromas and one fibrosarcoma derived from cutaneous ganglion cell-like cells. Among these patients, nine were male and one was female. Histologically, these abnormal masses were composed of spindle-shaped or polygonal neoplastic 'ganglion cell-like' cells with abundant amphophilic vacuolated cytoplasm. Immunohistochemically, these neoplastic cells were stained for vimentin, S100, and neuron-specific enolase. Out of 9 males, 3 showed positive reactions to the androgen receptor. This report provides a detailed histologic and immunohistochemical characterization of atypical fibroma, fibrosarcoma, and the tumorigenesis of ganglion cell-like cells in Djungarian hamsters.
