The Role of Bronchoscopic Therapy in Bronchial Granular Cell Myoblastoma: Presentation of Three Cases

Tracheobronchial granular cell myoblastoma (GCM) is rare. Although the tumor has some malignant properties, it is considered benign, and there is no consensus regarding treatment. Three cases are reported here. Bronchoscopic treatment in patients with GCM may be attempted as a first approach in case the tumor is intraluminal.

Granular cell myoblastoma of the breast.

JOl/maloJ r Five cases of granular cell myoblastoma of the breast are reported, all occurring in Negroes. In none was the correct diagnosis made preoperatively. Because this benign tumour has many features of carcinoma, errors in clinical and n:ammographic assessment may lead to unnecessary ilia tectomy. Thus, a histological diagnosis must be made on every apparently malignant lump before any f...

Retrobulbar granular cell myoblastoma.

Granular cell myoblastoma is a relatively uncommon lesion of debatable histogenesis, appearing as a small, solitary (but occasionally multiple) neoplasm and usually taking a benign course. The malignant counterpart has rarely been observed examples have also been found in virtually every organ or tissue of the body (Strong and others, I970), but only rarely in the orbit.
