To present our experience of intensity-modulated radiotherapy (IMRT) with simultaneous modulated accelerated radiotherapy (SMART) boost technique in patients with nasopharyngeal carcinoma (NPC). Sixty eight patients of NPC were treated between April 2006 and December 2011 including 45 males and 23 females with mean age of 46 (range 15–78). Stage(More)

We present a case of follicular dendritic cell sarcoma in a 48 years old Saudi female who reported with slowly progressive right sided extranodal neck mass associated with pulmonary metastasis. Clinical examination, histopathologic features including distinct immunostains combine together to make the rare diagnosis of follicular dendritic cell sarcoma. This(More)
Metastasis to the head and neck region from primary is rarest manifestation. Lung and breast carcinomas are the commonest malignancies to metastasize to the head and neck region.

Background: Linear accelerator (LINAC) based radiosurgery for a brain arteriovenous malformation (bAVM) is replacing gamma knife radiosurgery. We present clinical outcome, obliteration rates and predictor factors of treatment success following LINAC radiosurgery for bAVM which is not much addressed subject in Middle East. Methods: 13 patients who underwent(More)
We report a rare case of three head and neck malignancies in one patient. Squamous cell carcinoma of tongue and papillary thyroid carcinoma occurred as metachronous cancers in a patient with primary nasopharyngeal carcinoma. These three pathologically distinct malignancies of head and neck region in one patient is a rare phenomenon and is not reported so(More)
