Sebaceous carcinoma in solid organ transplant recipients

Area of Science:

• Oncology
• Dermatology
• Transplant Surgery

Background:

• Sebaceous carcinoma is rare but well-documented in immunocompetent individuals, often with poor prognosis and high metastasis rates.
• The impact of immunosuppression post-transplant on sebaceous carcinoma development and outcomes remains uncharacterized.

Purpose of the Study:

• To characterize sebaceous carcinoma in solid organ transplant recipients.
• To analyze the clinicopathologic features and outcomes of these rare tumors.

Main Methods:

• Retrospective analysis of 9 cases of sebaceous carcinoma post-solid organ transplantation at a single institution.
• Evaluation of clinicopathologic features, treatment modalities, and patient outcomes.

Main Results:

• Estimated prevalence of sebaceous carcinoma post-solid organ transplantation is 0.09%.
• Tumors predominantly occurred in extra-ocular locations, with only one case of metastatic disease (likely associated with Muir-Torre syndrome).
• Mohs micrographic surgery and wide local excision demonstrated equal efficacy with no recurrences.

Conclusions:

• Sebaceous carcinoma in solid organ transplant recipients typically presents in extraorbital sites and has a low metastatic potential.
• Both Mohs micrographic surgery and wide local excision are effective and acceptable treatment options for this patient population.
