“…Such structures were absent in both cases of DN. Our observations are consistent with previous data suggesting that OSHMD can reveal very fine pigmented structures corresponding to dots or globules, suggestive of BCC [ 2 ]. However, as either looped or branched vessels were present in both DN an BCC cases, the vascular pattern does not appear to be a distinctive feature of neither lesion type.…”

“…Finally, it could be speculated that the differences between aforementioned two types of vascular structures of BCCs present in H- and non-H-zones, which at the current state of knowledge are of uncertain significance, may gain further importance with the increasing use of high-resolution equipment and higher magnifications, including the use of optical super-high magnification dermoscopy which could shed additional light on the dermoscopic diagnostics in BCC and may allow to redefine vascular criteria in BCC [ 10 ].…”

Introduction Basal cell carcinoma (BCC) located on the face in the H-zone (nose, ears, eyes), the region corresponding to places of fusion of embryonic masses (EFP) has been associated with a higher risk of deeper invasion and more frequent recurrence. Aim To characterize the dermoscopic image of the vessels of BCC in the H-zone and non-H-zone. Material and methods A retrospective analysis of vessels in dermoscopic images of 120 BCC cases in the H-zone and non-H-zone (the rest of the face) was conducted. The H-zone consists of the nose, ears, eyes and the non-H-zone of the forehead, cheek, chin and the rest of the face and neck. Results Of the 120 lesions analysed, there were 41 (34.2%) in the H-zone and 79 (65.8%) in the non-H-zone. Arborizing vessels, as well as the short-fine-telangiectasias were the most predominant types of vessels present, and their frequency in the H- and non-H-zone was comparable. Significant differences were observed for the occurrence of glomerular and comma vessels, both of which occurred less frequently in the H-zone than in the non-H-zone. Conclusions The dermoscopic morphology of the vessels in BCC tumours in the H- and non-H-zones is generally similar, with differences in the presence of glomerular and comma vessels, which occur more frequently in the non-H-zone.

Introduction: Basal cell carcinoma (BCC) localized in the H-zone, the region of fusion of embryonic masses, has been associated with a higher risk of deeper invasion and more frequent recurrence. Objectives: The aim of the study was to compare dermoscopic features of BCC in H and non-H zone that may most appropriately characterize those two locations. Methods: Dermoscopy images of histopathologically confirmed BCCs from 120 patients were retrospectively analyzed. Dermoscopy features of BCC in H- and non-H zone were described and a comparative study of the dermoscopic pattern of BCC between the two locations was performed. Results: Of 120 BCC cases included in this study, 41 (34.2%) were located in the H-zone. The most frequent histological type was nodular (51.3% in H- zone and 61.6 % in non-H-zone) followed by superficial (5.1% and 19.8 % in H and non-H-zone respectively). In dermoscopy, there was a higher prevalence of ulceration (73.2% versus 43.6%, P < 0.001) in H-zone and a lower prevalence of brown globules (26.8% versus 53.2%; P = 0.01), when compared with the non-H-zone. Conclusions: Our results show that dermoscopic features of BCC on the face fulfill a typical pattern regardless of the region, except for the prevalence of the ulceration which is significantly more frequent in H-zone and the brown globules present significantly more often in the non-H-zone It can be hypothesized that H-zone might predispose to more aggressive course of BCC complicated by ulceration and consequently deeper tissue destruction.
