Multifocal Langerhans' cell histocytosis is a rare condition that can affect multiple organs and manifest in various scenarios. While the condition is more commonly found in children, it can also occur in adults.
A 43-year-old female presented with refractory otorrhea and had a rubbery neck mass in the left mid-cervical area, as well as an itchy eczematoid lesion in the left parietal area. The otic lesion was eventually resected, and histopathologic examination confirmed the diagnosis of Langerhans histiocytosis.
Although rare in adults, Langerhans histiocytosis should be considered as one of the differential diagnoses for ear canal polyps. If diagnosed, medical treatment should be pursued.
