Histologic Review of Sarcoidosis in a Neck Lymph Node

Abstract

Sarcoidosis is a multisystem granulomatous disease of unknown etiology. It may occur at any age, but is most commonly seen in young to middle age adults. Sarcoidosis remains more common in women regardless of geographic or racial boundaries. Although the etiology remains unclear, the most common explanation is that sarcoidosis is a disease of immunologic dysregulation triggered by an as yet unidentified environmental or microbial antigen in genetically susceptible persons. We review a case of sarcoidosis with was initially diagnosed in a neck lymph node that was removed for evaluation of metastatic squamous cell carcinoma with a discussion on the clinical and histologic characteristic of the disease.
