Asymptomatic Necrotizing Granulomatous Disease of the Neck With Unknown Etiology

Patients presenting with unilateral neck masses is not an uncommon occurrence in an otolaryngology clinic. Especially those with risk factors such as older age and a history of smoking or drinking along with certain characteristics of the mass including rapid growth, immobility, and the presence of other masses elsewhere in the head and neck that can lead to more concerning etiologies such as cancer. However, in those who are younger with non-tender unilateral mobile masses, the differential is wide. We present the case of a 30-year-old male who presented with a non-tender left-sided neck mass with no associated or systemic symptoms. Workup including labs for HIV, syphilis, and fungal stains was negative. Pathology demonstrated lymphadenitis with necrotizing granulomas with no recurrence of symptoms after excisional biopsy. The patient continued to have no associated symptoms or recurrent mass thus no further workup was deemed necessary. Although unilateral neck mass and lymphadenitis with necrotizing lymphadenitis have a broad differential diagnosis, this patient’s etiology continues to be unknown.
