BACKGROUND: We compared indomethacin therapy with the more aggressive approaches of anti-cancer chemotherapy and surgery in the treatment of isolated Langerhans cell histiocytosis (LCH) of bone in children. METHODS: Comparisons were made with respect to healing of the lesion without recurrence, time to radiological healing of the lesion, time to functional recovery, and complications related to treatment. RESULTS: Complete radiologic healing of the lesion (mean, 15.3 months) and functional recovery (mean, 5.6 months) were observed in all patients treated with either approach. No significant differences were noted in the time to complete radiologic healing or the time to functional recovery between the two groups. There were no recurrences with either approach until the last follow-up (mean, 56 months). Complications were common with anti-cancer chemotherapy, but indomethacin was well-tolerated. CONCLUSIONS: Indomethacin seems to be effective for treating isolated LCH of bone in children. Hence, morbidities associated with aggressive treatment approaches such as anti-cancer chemotherapy or surgery can be avoided.

Scurvy is very rare disease in industrialized societies. Nevertheless, it still exists in higher risk groups including economically disadvantaged populations with poor nutrition, such as the elderly and chronic alcoholics. The incidence of scurvy in the pediatric population is very low. This study reports a case of scurvy in a 5-year-old girl with cerebral palsy and developmental delay based on MRI findings.
