Granular-cell tumor is an uncommon cause of breast mass in premenopausal women that presents as a painless chronic lump. It mimics infiltrating carcinoma clinically and radiologically. Granular-cell tumor is usually benign, and the treatment is wide local excision. Definitive pre-operative diagnosis helps to avoid unnecessary mastectomy. We present clinical, mamographic, and sonographic charact...

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. Von Bahr (I938) reporte...

A 42-year-female patient presented with a swelling on the left side of the face for the past 10 years. The radiograph shows multilocular radiolucency with evidence of root resorption. Histopathology reveals fibrous connective tissue exhibiting numerous odontogenic epithelial islands with peripheral tall columnar cells showing a reversal of polarity. The center of the island shows stellate retic...

A case of granular cell myoblastoma which metastasized with fatal results is described. The literature relating to similar cases is reviewed and a total of 13 acceptable cases is listed.

Granular cell astrocytoma (GCA) is an uncommon type of granular cell tumours (GCTs) in the central nervous system. Granular cells in these tumours are of enigmatic origin. We report a case of cerebral GCA in a 59-year-old man who suffered from diabetes and Addison-Biermer disease. The tumour was localized in the left parietal lobe. Microscopically, the tumour was almost entirely composed of lar...
