Summary
Routine ear examinations in dermatology are crucial for early detection of external ear melanoma. Prompt diagnosis and surgical treatment significantly improve patient survival rates for this rare cancer.
Area of Science:
- Dermatology
- Oncology
Background:
- External ear melanoma is a rare malignancy.
- Early diagnosis and treatment are critical for patient survival.
Observation:
- Four clinical cases of external ear melanoma are presented.
- Patients aged 60-81 with melanocytic lesions underwent physical and dermoscopic examination.
- Lesions suggestive of melanoma were identified in the outer ear.
Findings:
- Surgical excision was the primary treatment modality.
- Histopathological studies confirmed melanoma diagnoses.
- Early-stage diagnosis facilitated timely therapeutic intervention.
Implications:
- Routine dermatological examination of the ears is vital for identifying potential melanomas.
- Early detection and treatment positively impact overall survival in external ear melanoma patients.

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.

The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.

The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...
