Head and neck adnexal skin cancers

Area of Science:

• Dermatology
• Oncology
• Pathology

Background:

• Adnexal carcinomas (AC) are uncommon skin malignancies primarily affecting older adults.
• These tumors frequently occur on the head and neck and are associated with sun exposure, radiation, and immunosuppression.

Purpose of the Study:

• To review the pathogenesis and management of adnexal carcinomas.
• To emphasize the importance of early identification and accurate diagnosis for improved patient outcomes.

Main Methods:

• Review of current literature on adnexal carcinoma.
• Analysis of diagnostic criteria and treatment modalities, including surgical approaches.

Main Results:

• Adnexal carcinomas can arise de novo or from benign precursors and may indicate hereditary syndromes.
• Accurate diagnosis requires adequate biopsy; superficial excisions can lead to misdiagnosis.
• Wide surgical margins (≥1 cm) are recommended; Mohs surgery is beneficial for cosmetically sensitive areas.

Conclusions:

• AC prognosis is categorized into good, intermediate, and poor based on recurrence and metastasis risk.
• This classification guides adjuvant treatment decisions and follow-up protocols.
• Understanding risk factors, pathogenesis, and treatment is vital for optimal adnexal carcinoma management.
