Sebaceous carcinoma in Japanese patients: clinical presentation, staging and outcomes

Abstract

In this Japanese cohort, an eyelid mass was the main clinical presentation of sebaceous carcinoma. Contrary to previous reports, T2a tumours smaller than 10 mm were associated with regional nodal metastases.

14-year case series of eyelid sebaceous gland carcinoma in Chinese patients and review of management

“…The Indian cohort also found that the risk of systemic metastasis and death was related to an increasing T category 9. However, in the Japanese cohort, the authors found that tumours even smaller than T2a were associated with tumour metastasis 8. This may be because of the difference in the primary modality of treatment employed.…”

Dermoscopic features of ocular and extraocular sebaceous carcinomas

“…Watanabe et al . reported two of 37 sebaceous carcinomas with primary T2a tumors measuring 5 mm and 7 mm, respectively, developed nodal metastases during follow up . This result shows that even small lesions present a risk of metastasis.…”

Recurrent sebaceous carcinoma of the eyelid: Outcome after postoperative reirradiation

“…Nodal metastases were seen in 8% of the patients, with preauricular being the predominant site. The primary tumor with the stage of T3a or greater has been significantly associated with local recurrence . The locally aggressive nature of sebaceous carcinoma has been reported .…”
