32 year-old male, previously healthy, with slowly-progressive right and left cervical lymphadenopathy over the past three years. He first noted the development of a mass on the lateral neck below the ear three years ago. This mass was non-tender and remained stable at approximately the size of a marble for nearly one year. He later developed more and larger masses, but never experienced any constitutional symptoms like fevers, night sweats, fatigue or weight loss. Examination reveals a healthy, well-nourished male with multiple, hard, mobile, non-tender right posterior cervical and submandibular lymph nodes and a large left supraclavicular lymph node, protruding above the clavicle and measuring ~4x3cm.

Imaging:

He has undergone several diagnostic procedures during this time including aspirations and core biopsies with inconclusive pathology and he is currently admitted for an excisional biopsy of the supraclavicular lymph node. Infectious and rheumatologic workup has remained negative including: HIV, bartonella, Quantiferon TB Gold, cocci, histo, toxo, CMV, EBV, ANA, RF, ACE.

The patient tolerated the excisional biopsy without complication and was discharged. Preliminary pathology suggests Castleman’s disease.
