External Auditory Canal Mass: A Case Series of Squamous Cell Carcinoma

Introduction: Squamous cell carcinoma of the temporal bone is extremely rare comprising 0.2% of all tumors of head and neck. Symptoms are nonspecific and may be mistaken for other more benign conditions as otitis, cholesteatoma and polyp. Hence, this condition may present as a diagnostic challenge....

description Introduction: Squamous cell carcinoma of the temporal bone is extremely rare comprising 0.2% of all tumors of head and neck. Symptoms are nonspecific and may be mistaken for other more benign conditions as otitis, cholesteatoma and polyp. Hence, this condition may present as a diagnostic challenge. Case Discussion: We describe a case series of three patients who presented with external auditory canal (EAC) mass. The most common signs and symptoms are pruritus, decreased hearing and yellowish discharge. They were initially treated with otic antibiotics which afforded no relief. The first case is a 51 year-old female who underwent wide excision of the right ear canal and middle ear mass and right temporal craniotomy. Histopathology showed moderately differentiated squamous cell carcinoma with temporal tumor and subdural extension consistent with metastasis. The second case is a 53 year-old male who refused surgical management. He was non-compliant with work-up and follow-up and later on presented with left facial asymmetry and headache. CT scan showed a left inner and middle ear canal mass with extension to the auditory canal and protrusion into the left cerebellar hemisphere. Punch biopsy of the left EAC mass was done and pathologic report showed well-differentiated squamous cell carcinoma. Lastly, a 54 year old male who underwent Radical mastoidectomy with histopathology reports of a moderately differentiated squamous cell carcinoma. Conclusion: Standard treatment modality is still unclear because of the rarity of this condition. However, surgical resection with negative margins followed by concurrent chemotherapy and radiation is the most commonly performed approach1. For the above-mentioned patients, concurrent chemotherapy and radiation therapy was given which showed significant treatment response.
