Full Text

We read with interest the paper by Sethi et al titled "Childhood proptosis. The invaluable but overlooked peripheral blood smear".[1] The authors have highlighted the significance of peripheral blood smear examination in establishing the diagnosis of Acute Myeloid Leukaemia (AML). We must congratulate them for reviving the old concept.[2] We have reported four cases of childhood proptosis, three unilateral and one bilateral in the age group 4-11 years in 1984 where the diagnosis of AML was confirmed by peripheral blood smear examination. In the same article we had recommended that any patient with proptosis, either unilateral or bilateral should have a peripheral blood smear evaluation by experienced haematologists. Whatever the reason, the idea has not yet become popular despite its mention as early as 17 years ago in the same journal and from same centre.[2]

We agree with the authors that CT scan being an expensive tool is not available to most district hospitals. Incisional biopsy, a less expensive but surer tool for diagnosis cannot be done at peripheral centres due to lack of histopathological facilities. On the other hand, peripheral blood smear is the most easy and inexpensive mode of evaluation and is sufficient to diagnose AML even in the absence of systemic features.

Finally, we would like to commend the authors for stressing a simpler modality of diagnosis. We wonder how many of us would have missed the diagnosis by depending on costlier investigations. We once again appreciate the authors concern and thank them for sharing our view.
