BACKGROUND: Crystal storing histiocytosis (CSH) is a @entity395 characterized by accumulation of histiocytes containing crystalline material inclusions. This entity can be misdiagnosed as @entity5 . We present a case of idiopathic CSH mimicking @entity957 in a cervical lymph node and review of literature regarding this rare entity. METHODS AND RESULTS: The @entity1 was a 70-year-old @entity1 with a medical history of @entity957 of the right base of the tongue. The @entity1 presented with an enlarged cervical lymph node, which was clinically diagnosed as @entity189 . At intraoperative consultation, it was unexpectedly discovered that the lymph node exhibited extensive histiocytosis containing crystal materials. Final pathology identified "crystal storing histiocytosis" because of @entity527 . No @entity189 was seen. CONCLUSION: After 10 months of follow-up, the @entity1 is disease free. To the best of our knowledge, this unusual clinical presentation is the first to describe CSH mimicking a @entity189 .    2015 Wiley Periodicals, Inc. Head Neck 38: E95-E98, 2016.
