BACKGROUND: There is a growing concern about childhood sarcomas, with recent studies suggesting an increase in the frequency of childhood sarcomas in sub-Saharan Africa. This study was carried out to determine the pattern of childhood sarcomas in Jos, North Central Nigeria and to compare the data obtained with other previous related studies. METHODS: Review of the Jos University Teaching Hospital cancer registry from January 2001 to December 2010. Data of all children (0-15 years) in the data base were retrieved for analysis. RESULTS: Two hundred and ten histological diagnosis of malignancies were made in children over the period, with 81 cases (39%) being childhood Sarcomas. The sarcomas occurred predominantly in males (54%) with male/female ratio of 2:1. The minimum age was 2 months and the maximum age was 15 years. Soft tissue sarcoma (STS) was the most predominant group which accounted for 73 cases (90%) of all sarcomas seen. Rhabdomyosarcoma (RMS) was the most common STS, it accounted for 65 cases (89%) of the STS and 80% of all the sarcomas. This is followed by Kaposi Sarcoma (KS) accounting for 6.9% of STS. There were 8 cases of Osteosarcoma which accounted for 10% of all the sarcomas. Embryonal RMS predominated in the very young children while all other sarcomas affected the older children. Extremities were the sites of predilection for most of the sarcomas (36%). Seventeen (17) cases of the RMS were of superior prognostic group, 34 (54%) were of intermediate prognostic group while 24 cases (37%) were of poor prognostic group. CONCLUSION: Childhood sarcomas are common in our environment and RMS is the single most common sarcoma while the non-rhabdomyosarcoma soft tissue sarcomas (NRSTS) are rare.
