A Case of Rapidly Growing Extraocular Sebaceous Carcinoma

Area of Science:

• Dermatology
• Oncology
• Pathology

Background:

• Sebaceous carcinoma is a rare malignancy originating from sebaceous glands, accounting for less than 1% of skin cancers.
• Accurate initial diagnosis can be challenging due to its rarity and varied presentation.

Purpose of the Study:

• To report a case of rapidly growing extraocular sebaceous carcinoma.
• To highlight diagnostic challenges and successful management of this rare skin cancer.
• To review relevant literature on sebaceous carcinoma.

Main Methods:

• Presentation of a clinical case involving a 93-year-old female with a rapidly growing cheek mass.
• Surgical management including wide excision, superficial parotidectomy, and reconstruction with a transposition flap.
• Histopathologic examination for definitive diagnosis and margin assessment.

Main Results:

• Initial histopathology suggested basal cell carcinoma, but the excised mass was confirmed as poorly differentiated sebaceous carcinoma.
• Complete tumor resection with clear margins was achieved.
• The patient experienced a favorable treatment outcome following surgical intervention.

Conclusions:

• Sebaceous carcinoma diagnosis can be difficult, often requiring thorough histopathologic evaluation.
• Prompt surgical management, even for rapidly growing tumors, can lead to successful outcomes.
• This case underscores the importance of considering rare diagnoses in dermatology and head and neck surgery.
