Superficial epithelioma with sebaceous differentiation (SESD) is a rare benign neoplasm with peculiar histopathologic characteristics, which occurs in aged skin. We report upon a case of SESD occurring on the left upper back, which histopathologically is a superficial, multilobular tumor with numerous basaloid cells mixed with sebaceous cells attached to the overlying epidermis. This case represents a solitary benign neoplasm without any associated malignancy.

OBJECTIVETo investigate the fine needle aspiration cytology (FNAC) features and differential diagnosis of eyelid sebaceous gland carcinoma.

METHODSFour cases of eyelid sebaceous gland carcinoma diagnosed by FNAC were reported and confirmed by biopsy. Three of the cases were in early stages with tumor sizes smaller than 10 mm in diameter and without metastasis. The smears were stained by routine H & E and SudanIII methods. The cytologic findings were described and compared to corresponding histological features, and moreover, compared to chalazion, pilomatrixoma and eyelid basal cell carcinoma.

RESULTSNeither hemorrhage nor infection were found after the examination. Abundant cells were observed in the sebaceous carcinoma FNAC smears. Two types of tumor cells were found: one showed tumor cells differentiating toward sebaceous gland, with large pale cells and vacuolated cytoplasm, the other demonstrated poorly-differentiated cell with dark and irregular nuclei. Numerous vacuoles with inequality of size were found in cytoplasm or in background in all four cases, and the SudanIII stain showed that these vacuoles contained lipid. Some smears demonstrated cells with basaloid, fusiform or squamous features, corresponding to various histopathological types. In contrast, smears of chalazion displayed inflammatory granuloma, containing several types of inflammatory cells without malignant cells. Smears of pilomatrixoma were cellular with three cell populations, which included bland sheets of basaloid cells, nucleated basophilic cells and anucleated keratinized "ghost cells", along with calcific debris. The smears of basal cell carcinoma were typically less cellular, more tightly cohesive and had smaller clusters of uniform hyperchromatic basaloid cells without vacuolization in cytoplasm or background. Overall, the cytological features of eyelid sebaceous carcinoma were distinct from those of chalazion, pilomatricoma and basal cell carcinoma.

CONCLUSIONSFNAC is a safe and effective approach for the diagnosis of eyelid sebaceous carcinoma and lipid stain is useful in differential diagnosis. The application of FNAC may be important in reaching an early diagnosis and initial treatment of eyelid nodule.

Ocular sebaceous carcinoma (OSC) is an uncommon malignancy with a potential to recur and metastasize. Some characteristics of sebaceous carcinoma, such as female preponderance, shown in the present series during 11-year period at Korea Cancer Center Hospital, led us to study their hormone receptors and c-erbB-2 expression. c-erbB-2 overexpression was very common (83%) in OSC, and was not associated with pathologic findings or clinical outcome. Interestingly, estrogen and progesterone receptor was detected in 4 and 2 cases, respectively, suggesting a role of hormonal influence on this neoplasm. Immunohistochemical and clinicopathologic features of 18 cases of OSC in Korea are presented.

We report a sebaceous carcinoma confined to the corneoscleral limbus without involvement of the eyelid. A 60-year-old man, who showed multiple masses on the corneaoscleral limbus and limbal ulceration but with normal eyelids, underwent surgical en-bloc excision of the masses. Histopathologic examination revealed a sebaceous carcinoma. Three weeks after excision, multiple pagetoid recurrences were found along the bulbar conjunctiva 2 mm away from the limbus. After the application of topical mitomycin C, the pagetoid spread regressed completely. After a 2 year follow-up, no other local or systemic recurrences were observed. This report shows that the ulcerative mass which is confined to only the corneoscleral limbus may be a sebaceous carcinoma even without eyelid involvement. Topical mitomycin C may be effective for treating pagetoid spread of sebaceous carcinoma of limbal origin.

BACKGROUNDIn humans telomerase is expressed in most cancers and immortal cell lines, and activation of telomerase may play important roles in tumorigenesis and immortalization. This study was to investigate the roles of telomerase activity (TA) and human telomerase RNA (hTR) in sebaceous carcinoma of the eyelid.

METHODSThe telomerase repeated amplification protocol (TRAP) was used to demonstrate telomerase activity in 12 cases of sebaceous carcinoma of the eyelid. In situ hybridization (ISH) was used to demonstrate the expression of hTR in 55 cases of paraffin-embedded sebaceous carcinoma of the eyelid, and the results were compared with the proliferative index determined by Mib-1 immuno-labeling, histological patterns and recurrence of the tumor.

RESULTSDifferent telomerase activity was shown in the 12 cases of sebaceous carcinoma of the eyelid. The positive expression of hTR was 85.5% (47/55) in tumor cells, but not in the adjacent tissues. The positive expression of hTR was correlated with the proliferative activity (as assessed by Mib-1 immunolabelling, r = 0.942, P < 0.001) and the differentiation of sebaceous carcinoma of the eyelid (chi(2) = 17.621, P < 0.001), but not significantly related to tumor recurrence. The level of hTR expression increased with the decrease of differentiation of sebaceous carcinoma of the eyelid.

CONCLUSIONSThe results suggest that the up-regulation of telomerase expression plays some roles in tarsal gland carcinogenesis, and the expression of hTR is a useful marker for malignant degree of sebaceous carcinoma of the eyelid.
