Basal Cell Carcinoma of the External Auditory Canal – Unusual Site: A Case Report

Malignant tumor originated from external auditory canal (EAC) is very rare with an annual incidence of around 1 per million. Yet, basal cell carcinomas are less frequent than squamous cell carcinomas. Nevertheless, it is difficult to determine if their prognosis is better, as in other areas of the body. Due to the rarity of malignant tumor of EAC, there is no widely accepted treatment modality yet. But basal cell carcinoma, is known to be less aggressive tumor than squamous cell carcinoma and can be removed with a minimal safety margin and has a better treatment result. In this case report, we experienced a case of basal cell carcinoma (BCC) in the EAC, confined in the cartilaginous portion of EAC, presented with intermittent otorrhea and pruritis in the right ear. The patient was treated with local excision of the lesion with a safety margin and direct closure. No recurrence or complications were noted in the first postoperative year.

A rare variant of first branchial cleft fistula

Objective: To report an extremely rare variant of first branchial cleft anomaly.Case report: A-13-year old boy presented with the chief complaint of persistent right aural discharge since infancy. On examination, a 1 mm fistulous opening was present in the floor of cartilaginous portion of external auditory canal. And scanty watery discharge came out through this opening when the patient asked to swallow. Sinogram through discharging meatal opening showed a thick irregular tract about 5 cm length traversing the soft tissue of neck extending from the floor of right external auditory canal to the lateral pharyngeal wall and spillage of contrast into the oral cavity.Conclusion: This was an extremely rare variant of first branchial cleft fistula. Due to the rarity of this disease, clinical misdiagnoses and inappropriate management may lead to recurrence and complications. For better prognosis, appropriate diagnosis and surgical planning are very important. Key words: Objective: To report an extremely rare variant of first branchial cleft anomaly.
