Myofibroblastoma tumour of the breast

Myofibroblastomas are an unusual benign tumour of the breast predominantly affecting elderly males in their sixth to seventh decade. Recently, quite a few cases have been reported in women [3]. Myofibroblastoma are unusual rapidly growing benign mesenchymal tumours of the breast. These tumours tend to share morphological and immunohistochemical features with solitary fibrous tumours. Myofibroblastomas are typically a bland-looking spindle cell tumour exhibiting expression of vimentin, desmin and CD34 in most cases [5]. The term myofibroblastoma was first coined by Toker et al in 1981 to indicate a bland-looking spindle cell neoplasm with a variable myofibroblastic differentiation [7], and later another case was reported by Wargotzin in 1987 [3].
