Abstract:
Desmoplastic fibroblastoma is a rare but distinctive fibrous benign soft tissue tumor that presents a slowly growing, painless, fibroproliferative mass. Occuring in patients of various ages, it appears hypocellular microscopically, and consists of widely spaced bland spindles or stellar-shaped cells that are embedded in rich wavy collagenous or myxocollagenous stroma. Desmoplastic fibroblastoma was first characterized by Evans in 1995. Thereafter, there were several reports of desmoplastic fibroblastoma that it occured commonly in the upper extremity including regions such as shoulder, upper arm, and lower extremity, followed by the head and neck region. But there was no report of occurrence at the ear. We report our experience of desmoplastic fibroblastoma with histopathologic confirmation: we removed a mass at the mastoid cavity and external auditory canal. We also provide a review of literature related to it.
