Abstract
- Proliferative fasciitis is a rare, rapidly growing, pseudosarcomatous nodule of subcutaneous tissue. It commonly occurs on the extremities. Lesions on the head and neck are exceedingly rare. Histopathologically, it is characterized by several large basophilic ganglion-like cells deposited in a myxoid stroma with spindled cells. Herein, we report a case of a 54-year-old man who noticed a nodule on his right cheek about six months before examination. At first, its size abruptly increased, and then remained without any change in size. Microscopically, many basophilic ganglion-like cells and spindled cells were deposited in a myxoid stroma. Immunohistochemically, ganglion-like cells and spindled cells were strongly positive for vimentin and weakly positive for smooth muscle actin and CD68. Although it was not radically excised, the lesion has not been found for 3 months.
