Sebaceous carcinoma is a rare cutaneous malignancy that is most frequently found in the eyelids with an estimated risk of regional lymph node metastasis in the 8% to 14% range. The authors have previously reported the use of sentinel lymph node biopsy and microscopically positive sentinel lymph nodes in various eyelid and conjunctival cancers, including conjunctival and eyelid melanoma and Merkel cell carcinoma. The authors herein describe the first successful identification of a microscopically positive sentinel lymph node in a patient with sebaceous carcinoma of the eyelid, suggesting that sentinel lymph node biopsy for sebaceous carcinoma of the eyelid deserves further investigation.
[Show abstract][Hide abstract] ABSTRACT: Sebaceous carcinoma of the eyelid is a very rare slow-growing tumor and is considered an aggressive eyelid neoplasm. It can reach mortality rate of about 6%. Diagnosis is often delayed because of its ability to masquerade as other periocular lesions, both clinically and histologically. We present three cases of sebaceous carcinoma, with different surgical outcomes, showing the importance of early diagnosis.
[Show abstract][Hide abstract] ABSTRACT: To assess lymph node invasion through the use of sentinel lymph node biopsy (SLNB) in conjunctival and eyelid tumor patients and ascertain the impact of this technique in therapeutic management recommended by the multidisciplinary consensus committee.
A single center prospective nonrandomized clinical study was conducted between January 2008 and January 2010. Seventeen patients were included: 4 (2 conjunctiva and 2 eyelid) melanomas, 4 eyelid Merkel cell tumors, 8 (2 conjunctiva, 2 eyelid, 2 eyelid and conjunctiva, 2 cornea and conjunctiva) squamous cell tumors, and 1 eyelid meibomian carcinoma. Preoperative lymphoscintigraphy was done the day before surgery to label lymph node(s). The surgical biopsy was then performed along with an extemporaneous pathological examination followed by secondary complete lymph node dissection only in instances of positive histology.
In all cases, one or more sentinel lymph nodes were identified (3-13). Two biopsies (1 Merkel cell carcinoma and 1 squamous cell carcinoma) revealed neoplastic invasion and led to complete cervical node dissection. Adjunct regional treatment was indicated for 1 melanoma, for 4 Merkel cell tumors, and for 2 squamous cell carcinomas. One false negative result was noted in the group of squamous cell carcinomas after 6 months, and it was treated. No relapse or death was observed for the other 16 patients. The mean overall follow-up was 18.2 months.
As in previous studies, we found that SLNB for eyelid and conjunctival tumors is safe and effective in identifying microscopically positive SLNs. This procedure may also revive interest in the study of cervicofacial lymphatic drainage. Our current investigation is to be expanded and extended to other medical teams.

[Show abstract][Hide abstract] ABSTRACT: To determine whether T category of the American Joint Committee on Cancer (AJCC) TNM staging system for eyelid carcinoma, 7th edition, correlates with lymph node metastasis, distant metastasis, and survival in patients with sebaceous carcinoma of the eyelid.
Retrospective, cohort study.
Fifty consecutive patients treated by 1 author (BE) for eyelid sebaceous carcinoma between May 1999 and August 2010.
Each tumor was staged according to the AJCC 7th edition TNM criteria. The Kaplan-Meier method was used to determine associations between disease-specific survival and (1) T category at presentation, (2) lymph node metastasis, and (3) distant metastasis.
T category at presentation, nodal metastasis, survival.
The study included 37 women and 13 men (median age, 68.5 years; range, 44-86 years). Forty-four patients were white, 5 were Hispanic, and 1 was Asian. TNM designations were TXN0M0, 7 patients; T1N0M0, 4 patients; T2aN0M0, 12 patients; T2bN0M0, 11 patients; T2bN1M0, 2 patients; T2bN1M1, 1 patient; T3aN0M0, 2 patients; T3aN1M0, 5 patients; T3bN0M0, 1 patient; T3bN1M0, 1 patient; T3bN0M1, 2 patients; T4N0M0, 1 patient; and T4N0M1, 1 patient. T category at presentation was significantly associated with lymph node metastasis (P = 0.0079). No tumors with T category better than T2b or smaller than 9 mm in greatest dimension were associated with nodal metastasis. Five patients (10%) died of disease during follow-up. Their TNM designations were T2bN1M1, 1 patient; T3bN0M1, 2 patients; T4N0M0, 1 patient; and T4N0M1, 1 patient. No tumors smaller than 12 mm in greatest dimension were associated with distant metastasis or death. T category was significantly associated with disease-specific survival (P = 0.0009). Disease-specific survival was poorer among patients with T category of T3a or worse (P = 0.035).
T category in the 7th edition of the AJCC TNM staging system for eyelid carcinoma correlates with outcomes in patients with sebaceous carcinoma of eyelid. On the basis of the present findings, it seems reasonable to recommend sentinel lymph node biopsy or at least strict regional lymph node surveillance for patients with eyelid sebaceous carcinoma with tumors of T category T2b or worse or 10 mm or more in greatest dimension.
