Sebaceous carcinoma of the nose: multi-focal presentation?

Area of Science:

• Dermatology
• Oncology
• Head and Neck Surgery

Background:

• Sebaceous carcinoma is a rare malignant neoplasm originating from sebaceous glands.
• Nasal sebaceous carcinoma is exceptionally uncommon, often presenting as a localized mass.

Observation:

• A 71-year-old male presented with a mass in the right nasal vestibule.
• Surgical excision and reconstruction with a nasolabial flap were performed.
• Histopathological examination confirmed sebaceous carcinoma.

Findings:

• A second, distinct sebaceous carcinoma lesion developed in the contralateral nostril three months post-operatively.
• This represents a rare multi-focal presentation of sebaceous carcinoma within the nose.

Implications:

• Multi-focal sebaceous carcinoma of the nose requires careful surveillance due to potential for new primary lesions.
• This case expands the understanding of sebaceous carcinoma presentation and behavior in the nasal region.
