We found that no significant difference was seen in the histologic features and the expression of E-cadherin, Ki, and PHH3 between the two groups; thus supporting the theory that CSHR and LCH represent different ends of a spectrum of the same condition.
Identification of CD via immunohistochemistry may be formally used in the future to diagnose the disease. Except for S protein, these markers are rarely used nowadays. Thorough initial evaluation and close follow-up is mandatory, even for children with self-regressive forms of the infancy type.
LCH can be found in any race. Other potential cellular origins for LCH now include dermal Langerin plus dendritic cells, lymphoid-tissue resident Langerin plus dendritic cells.
