title: Fibrous histiocytoma of lung--a clinicopathological study of two cases.
abstract: Two cases of fibrohistiocytic tumours of the lung are presented and histogenesis of this group of this group of tumours is discussed. An essentially biphasic pattern of histiocytes and fibroblasts, and the presence of myofibroblasts and undifferentiated mesenchymal cells is similar to the fibro histiocytic neoplasms in other locations.
