Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Background:

Carcinomas of the external auditory canal (CEAC) are rare malignancies.
Treatment guidelines for CEAC are not well-defined.
This study addresses the therapeutic management of CEAC patients.

Purpose of the Study:

To discuss the therapeutic management of patients with Carcinomas of the External Auditory Canal (CEAC).
To highlight the importance of early diagnosis and imaging in CEAC treatment.

Main Methods:

Retrospective study over 11 years (2010-2021) including 8 patients with primary CEAC.
Data collected on demographics, symptoms, physical signs, radiological findings, surgical procedures, and follow-up.
Tumor staging based on the Pittsburgh classification.

Main Results:

Median age of patients was 58 years.
Common symptoms included hearing loss, otorrhea, otalgia, and facial palsy.
Tumor stages ranged from T1N0M0 to T4bN0M0.
Surgical interventions included local resection and lateral temporal bone resection with parotidectomy and neck dissection.
Adjuvant or exclusive radiotherapy was administered in several cases.
Histopathology revealed squamous cell carcinoma, basal cell carcinoma, and adenoid cystic carcinoma.
Six out of eight patients had favorable follow-up without recurrence; one patient experienced disease progression and died.

Conclusions:

Optimal treatment for CEAC necessitates early diagnosis.
Careful imaging assessment of tumor extension is vital for tailoring treatment.
Treatment frequently involves a combination of surgery and radiotherapy.
