Leiomyomas or benign tumours of smooth muscle origin are extremely rare in the nose, due to the paucity of significant masses of smooth muscle in this region. A review of the literature revealed only six cases of leiomyoma (Fu and Perzin, 1975; Kambayashi, 1978; MacCaffrey et al., 1978; Maesaka et al., 1966; Kotaka and Furuya, 1973) previously reported and no case of nasal leiomyoblastoma. This variety of benign smooth muscle tumour has been mostly described in the gastrointestinal tract and uterus (Stout, 1962). In this paper we report a case of an unusual nasal leiomyoma arising from the middle turbinate. We believe it is the first in the literature.

Fibro-Histiocytic neoplasms are uncommon in the respiratory tract. This paper presents a clinical and histological description of a case of fibrous histiocytoma at the level of the third tracheal ring. This case shares some features with the four cases previously described, viz., the growth occurs mainly in young adults; recurrences are common; and all have shown similar benign histological patterns. Ultrastructural investigations confirmed the fibro-histiocytic nature of the neoplasm.
