Soft tissue and visceral sarcomas in Irish patients. A preliminary report from the Dublin Soft Tissue Tumour Panel.

Sarcomas of the soft tissues and viscera are a diverse group of uncommon neoplasms that often present difficult diagnostic and management problems. The Dublin Soft Tissue Tumour Panel prospectively reviewed pathology material from 137 patients of four Dublin teaching hospitals between January 1989 and August 1990. The prevalence of sarcomas in Irish patients was found to be similar to that estimated for the United States. The most common sarcoma of soft tissues was malignant fibrous histiocytoma (14) and the most common visceral sarcoma was leiomyosarcoma (10). The most problematic diagnoses were 3 peripheral neuroepitheliomas (extraskeletal Ewing's sarcomas) which occurred in patients aged 19-27 years, distinctly younger than the typical adult sarcoma patient. Clinical follow-up is in progress and will be combined with the findings of a linked retrospective study, to facilitate evaluation of all aspects of management.
