“…27 In describing the dermoscopic features of the glomus tumor, a wide variety of terms have been used in the literature. 9,10,[16][17][18][19][20][21] The primary purpose of our study is to investigate whether there is any finding of glomus tumor that cannot be detected by clinical examination but can be detected by dermoscopic examination.…”

“…15 The dermoscopic features of the glomus tumor have been described in a few case reports and series. 10,[16][17][18][19] In describing the dermoscopic features of the glomus tumor, the terms such as "structureless bluish area and linear irregular vessels," 16 "erythematous vascular area," 16 "pinkish bluish," 17 "structureless bluish patches mixed with linear irregular vessels," 18 "lamellar scaling of the nail plate," 18 "subungual linear and pink-whitish structure," 9 "localized structureless erythema," 10 "candy-cane appearance" (longitudinal red bands interspersed with longitudinal white bands), 10 "discreet linear vascular structures," 19 "deep red-purple discolored area with blurred borders," 20 "a band of longitudinal erythronychia," 20 "small red ramified vessels," 20 and "pinkish structureless pattern with arborizing vessels" 21 were used in the literature. The aim of this study is to determine the clinical and dermoscopic features of the cases in a subungual glomus tumor series and to investigate whether there is any finding of glomus tumor that cannot be detected by clinical examination but can be detected by dermoscopic examination.…”

Background and Objectives The dermoscopic features of glomus tumors have only been described in a few case reports. The aim of this research was to define the clinical and dermoscopic features of subungual glomus tumors. Methods Thirty‐two patients with subungual glomus tumors were evaluated retrospectively. Results On the photographs, longitudinal erythronychia, longitudinal leukonychia, punctate leukonychia, splinter hemorrhage, isolated capillaries, distal notching, distal subungual hyperkeratosis, onycholysis, and onychoschizia were found. There was no statistical difference between the rates of detection of these findings by evaluation from clinical photographs alone and from both clinical and dermoscopic photographs. While ramified vessels with bluish spots could be detected in only five of 26 cases with bluish spots in their clinical photographs, these ramified vessels were seen in 14 cases in bluish spots in dermoscopic photographs (P = 0.004). Compared to clinical examination, dermoscopy was able to detect blue spots in three more cases. Lesion duration was higher in the cases with ramified vessels (P = 0.018). Conclusions Dermoscopy seems to contribute to the clinical examination in displaying only ramified vessels located in bluish spots and in determining the localization of the subungual tumors. The presence of ramified vessel in the bluish spots is strongly related to lesion duration.

“…18,19 Nevertheless, there is no consensus on the most suitable term to describe these vessels. In this sense, terms such as 'ramified vessels', 12 'prominent telangiectatic vessels', 5 or 'linear irregular vessels' 13,14 have been used. In our experience, these vessels are mostly linear, moderately thin, with multiple bends and scarcely branched.…”

Background Glomus tumours (GTs) are benign cutaneous neoplasms derived from the neuromyoarterial apparatus with a strong predilection for acral sites, especially the subungual space. Current data regarding dermoscopy of these lesions are very limited. Objectives To analyse the dermoscopic structures and patterns seen in a large series of subungual (SUGTs) and extraungual glomus tumours (EUGTs) and to determine their diagnostic significance. Methods Clinical and dermoscopic images of 86 histopathologically proven cases of GTs (47 SUGTs and 39 EUGTs) collected from 9 hospitals in Spain, France, Italy, and Brazil were evaluated for the presence of dermoscopic structures and patterns. Similarly, 189 and 185 dermoscopic images of other ungual tumours and other extraungual non‐pigmented tumours, respectively, were evaluated for the same structures and patterns. Finally, we evaluate diagnostic testing accuracy calculating sensitivity (S), specificity (Sp), and positive and negative predictive values of the different patterns for the diagnosis of GT. Results Regarding SUGTs, four patterns were built from the combination of different structures. The pattern composed of a structureless purplish/red subungual spot with or without vessels reached the highest S (S1, 78.8%). The combination of a structureless purplish/red subungual spot and longitudinal erythronychia (LE) (S2) is highly specific (96.3%). Patterns S3 (proximal purplish/red subungual spot, LE, and distal notch) and S4 (bed subungual spot and onycholysis) are the most specific and exclusive of matrix and bed tumours, respectively. The most consistent pattern in EUGTs is composed of a structureless purplish‐white to reddish‐white homogeneous area and linear unfocused vessels (E) (S: 61.5%, Sp: 95.7%). EUGTs did not show lacunae, unlike other vascular tumours. Conclusions Dermoscopy is helpful in improving the diagnostic accuracy of GTs, not only in SUGTs but also when these lesions arise out of the ungual apparatus.
