Pigmented basal cell carcinoma of the eyelid in Hispanics

Skin Cancer in People of Color: A Systematic Review

BACKGROUND

People of African, Asian, Hispanic or Latino, Pacific Islander, and Native Indian descent are considered people of color by the Skin of Color Society (SOCS).

OBJECTIVES

In this study, we assess incidence, risk factors, clinical characteristics, histopathology, treatment, and survival for skin malignancies in people of color as defined by the SOCS, by systematically reviewing the literature.

METHODS

An electronic literature search of the PubMed, EMBASE, and MEDLINE databases was performed. Articles published from 1 January 1990 through 12 December 2020 were included in the search.

RESULTS

We identified 2666 publications potentially meeting the study criteria. Titles and abstracts of these studies were reviewed and 2353 were excluded. The full text of 313 articles were evaluated and 251 were included in this review.

CONCLUSION

Differences in incidence, patterns, treatment, and survival exist among people of color for cutaneous malignancies. Further research and initiatives are needed to account for and mitigate these differences.

Malignant Eyelid Tumors in India: A Study of 536 Asian Indian Patients

Purpose

To study the proportion of eyelid malignant tumors in an Asian Indian population and to review their clinical features and outcomes.

Methods

This is a retrospective study of 536 patients.

Results

The mean age at presentation with eyelid malignancy was 58 years. Histopathology-proven diagnoses of these patients included sebaceous gland carcinoma (SGC) (n = 285, 53%), basal cell carcinoma (BCC) (n = 128, 24%), squamous cell carcinoma (SCC) (n = 99, 18%), and miscellaneous tumors (n = 24, 4%). The statistically significant differences between eyelid malignant tumors included age at presentation, tumor location, and tumor extent. The clinicopathological correlation of SGC, BCC, SCC, and miscellaneous tumors was 91, 86, 46, and 38% (p = 0.001), respectively. Comparing SGC with BCC, SCC, and miscellaneous tumors, SGC was more commonly associated with tumor recurrence (21 vs. 3, 8, and 13%; p = 0.001), systemic metastasis (13 vs. 0, 4, and 13%; p = 0.001), and death (9 vs. 0, 4, and 0%; p = 0.004). Compared to SGC, BCC, and SCC, locoregional lymph node metastasis was more common with miscellaneous tumors (26 vs. 16, < 1, and 8%; p = 0.001) over a mean follow-up period of 19 months.

Conclusion

In Asian Indians, SGC is twice as common as BCC and 3 times more common than SCC. SGC is associated with poorer prognosis compared to other eyelid malignant tumors.
