title: Oro-facial sarcomas: a review of 88 cases in a Tertiary Institution in Nigeria.
abstract: BACKGROUND
  A sarcoma is a malignant tumour arising from connective tissue. The word sarcoma is derived from the Greek word, sarkoma meaning fleshy growth and presents either as a soft tissue or bony tumour. Sarcomas are rare in the oro-facial region compared to oral squamous cell carcinoma. The rarity of jaw sarcomas makes diagnosis sometimes challenging and the anatomy makes aggressive treatment difficult without causing unacceptable physiological, functional and cosmetic damage to the patient. The aim of this study was to examine the demographic pattern of patients with jaw sarcomas seen at the University College Hospital, Ibadan, Nigeria over a thirty year period.
  
  
  METHODS
  All histologically diagnosed cases of sarcomas of the oro-facial region from the Cancer Registry of the University College Hospital Ibadan and the histology records of the department of Oral Pathology, University College Hospital Ibadan from 1980-2010 were reviewed. Data was analyzed using SPSS version 18.
  
  
  RESULTS
  Eighty eight oro-facial sarcomas were seen consisting of sixteen different histological types. Osteogenic sarcoma was the most common type with 40 cases (45.5%). Osteogenic sarcoma occurred more in females than males with a male: female ratio of 13:27 and a mean age of 32.2 years (SD ± 15.7). Embryonal rhabdomyosarcoma had an equal male: female distribution with mean age of 7.0 years (SD ± 5.2) and peak age incidence in the first decade.
  
  
  CONCLUSIONS
  The findings in this study were generally in agreement with reports from Europe, and though, at variance with some African studies, they are mostly in agreement with large African series.
