Basal cell carcinoma in a black woman with syringomas Leena Bhat, MD, Leonard H. Goldberg, MD, and Ted Rosen, MD Houston, Texas
Basal cell carcinoma (BCC) is the most common neoplasm in the United States but occurs infrequently in black persons. In whites, BCC predominates, whereas squamous cell carcinoma is more common in blacks.1-3 Syringoma associated with BCC has been reported twice4* and has been found in association with pruritus vulvae,5 diabetes mellitus,6 epidermal cysts,7 and intradermal nevus.8 Syringoma has not been reported in blacks and is probably rare in this population. We describe a case of syringoma on the upper and lower eyelids and cheeks in a black woman with concomitant BCC.

CASE REPORT A 50-year-old black woman had a BCC on her left cheek (Fig 1, A). The patient also had numerous syringomas and seborrheic keratoses on the upper and lower eyelids and cheeks (Fig 1, B). She had no known white ancestors. Mohs micrographic surgery was performed. Additional biopsy specimens from the left cheek and the left lower eyelid confirmed the diagnosis of syringoma. DISCUSSION
Skin cancer in black persons accounts for 1.2% to 2.8% of malignancies.1 BCC in blacks usually occurs in the sun-exposed areas and has a similar age distribution to whites.1-3 However, in blacks, BCC can also occur in unusual places like the anus, prepuce, nipple, and in a nephrectomy scar.3 BCC in blacks appears to occur equally in men and women, in contrast to a male predominance in whites. The histologic and clinical features are

similar in both whites and blacks with the exception that pigmented BCC occurs more frequently in blacks. The pigment in dark skin and in the tumor can make the pearly, rolled border and telangiectases more difficult to detect1-3 and may lead to an erroneous diagnosis of seborrheic keratosis, dermatosis papulosa nigra,1 sebaceous adenoma, epidermal inclusion cyst,9 malignant melanoma, or nevocellular nevus.10 There are two reports on the coexistence of syringomas and BCC. Chui, Goldberg, and Pham5 described BCC, syringomas, and subclinical sweat duct proliferation in a 79-year-old white woman. Spitz, Stadecker, and Grande4 described 3 white women with syringomas or subclinical sweat duct proliferation and a BCC. Mehregan11 described a sweat duct cystic dilation that histologically resembled syringoma in association with superficial BCC. There are no reports of syringomas in blacks, and this suggests that they may be rare in this racial group. REFERENCES 1. Rosen T. Nonmelanoma skin cancer in black patients.
