“…Our results were similar to those reported by Sng et al, Kikuchi et al, and Cho et al [6, 17, 18]. This study, corroborated by reviews in other Asian countries, showed that HNBCC in ethnic Chinese and other Asian populations presented differently compared to the Caucasian population, whereby HNBCC commonly presented as nonpigmented nodules in male patients (Table 1) [6, 11, 17–19].…”

Objectives. This study aims to report our experience in the management of HNBCC in ethnic Chinese over a 10-year period. Methods. A retrospective review of all ethnic Chinese patients with HNBCC treated in a tertiary centre from 1999 to 2009. Results. From 1999 to 2009, 225 patients underwent surgical excision for HNBCC. Majority were elderly female patients. Commonest presentation was a pigmented (76.2%) ulcer (64.8%) over the nose (31.6%). Median skin margin taken on tumour excision was 2.0 mm; primary skin closure was achieved in 51.8%. Postresection skin margin was clear in 75.4%. Of those with inadequate skin margins, 56.7% opted for further treatment, 43.4% for observation. Recurrence rates were 2.6% and 13.8%, respectively (P = 0.106). Overall recurrence rate was 5.5%. Conclusions. HNBCC commonly presented as pigmented ulcers over the nose of elderly female patients in our locality. Adequate tumour excision ± reconstruction offered the best chance of cure. Reexcision of those with inadequate skin margins improved local tumour control.

“…Studies report on a higher frequency of superficial BCC (sBCC) on the trunk and lower legs of women, whereas the majority of nodular BCC occur on the head and neck of men [20,21]. Pigmentation is present in more than 50% of the tumors in skin of color, whereas less than 10% of BCCs in fair skinned individuals are pigmented (Figure 4) [22–26]. Furthermore, the concept of the signature pattern of BCC has been recently introduced, referring to the observation that multiple BCCs in an individual usually display a repetitive dermatoscopic pattern [27].…”

“…The frequency of pigmentation in BCC varies significantly among different races, since pigmented BCC accounts for less than 10% of BCCs in Caucasians, while the majority of BCCs in Hispanics and Asians and virtually all BCCs in black individuals are pigmented [22–26]. Notably, histopathological studies found trace amounts of pigment in a considerable percentage of clinically non-pigmented BCCs [24].…”

Following the first descriptions of the dermatoscopic pattern of basal cell carcinoma (BCC) that go back to the very early years of dermatoscopy, the list of dermatoscopic criteria associated with BCC has been several times updated and renewed. Up to date, dermatoscopy has been shown to enhance BCC detection, by facilitating its discrimination from other skin tumors and inflammatory skin diseases. Furthermore, upcoming evidence suggests that the method is also useful for the management of the tumor, since it provides valuable information about the histopathologic subtype, the presence of clinically undetectable pigmentation, the expansion of the tumor beyond clinically visible margins and the response to non-ablative treatments. In the current article, we provide a summary of the traditional and latest knowledge on the value of dermatoscopy for the diagnosis and management of BCC.

“…Recently, the incidence of BCC has been increasing among Asians, and the overall number of BCC cases has been growing rapidly1,8,9. The clinical characteristics of BCC appear commonly on the head and neck areas, and the most common subtype of BCC is the histopathologically distinct nodular type1,6-8. sBCC is primarily developed on the trunk, in contrast to the other subtypes2-4,7,9.…”

“…The incidence of basal cell carcinoma (BCC) has increased because of life style changes that include more outdoor activities1-4. Since there are several histological sub-types of BCC, accurate diagnosis is essential for selection of the proper treatment5.…”

Large Superficial Basal Cell Carcinoma Arising in the Scalp

Superficial basal cell carcinoma (sBCC), a rare sub-type of basal cell carcinoma, can frequently occur in younger patients. This cancer type preferentially develops on the trunk. However, other subtypes of BCC can occur in the head and neck, probably secondary to sunlight exposure. Especially, sBCC on the scalp has been rarely-reported, accounting for 0.7~0.8% of all sBCC cases. We report a case of 71-year-old female with a large sBCC of the scalp, an unusual site of sBCC.
