Description:
There is an array of complex and somewhat obscure conditions, seen but not always recognised by haematologists. Many of these provide enough diagnostic difficulty to meet the definition of anxiety-provoking consults. Three case-based examples of such conditions will be examined in detail.

Dr Kenneth L. McClain will unravel the mysteries of histiocytic disorders including Langerhan-cell and non-Langerhan cell types.

Dr Michael Linenberger will unravel the complexities of acute intermittent and congenital erythropoietic porphyrias.

Dr Ari Zimran will dissect why Gaucher disease is so commonly ignored in the differential diagnosis of difficult clinical scenarios.
