Mucosal melanocytic lesion in the middle ear extending to the inner ear and nasopharynx

Benign dendritic melanocytic proliferation is usually observed in the skin. We report an extremely rare case of a melanocytic lesion in the middle ear mucosa. Only 3 cases of melanocytic lesions in the middle ear have been reported. Our report is the only one that describes an adult with a melanocytic lesion in the middle ear that extended to the inner ear and nasopharyngeal mucosa. A 23-year-old female presented with profound sensory neural hearing loss and recurrent discharge from the right ear. Examination revealed a blue right tympanic membrane with a small perforation. Computed tomography scans and magnetic resonance imaging were performed. After surgical exploration and histopathological examination, the patient was found to have a benign melanocytic lesion in the right middle ear. Melanocytic lesions are commonly found in the skin. There are no previous reports have described adult patients with melanocytic lesions in the middle ear that extend to the inner ear and nasopharynx, which cause profound hearing loss with recurrent ear discharge. These patients require regular follow-up to assess the progression of the lesion and to watch for any malignant behavior.
