“…From this study, we believe the papillated acanthotic epidermis corresponds to the marginal whitish rims. Inside each rim, dilated vessels in the stroma between the elongated rete ridges were visible as linear and hairpin vessels dermoscopically, similar to the appearance in psoriasis and clear cell acanthoma . Furthermore, dermoscopy under compression (similar to diascopy) resulted in disappearance of vessels, and yellow dots and debris, which are thought to correspond to lipid‐laden foam cells, became visible.…”

We report three cases of verruciform xanthoma (VX) in male patients aged 82, 88 and 39 years, respectively. The clinical appearance was of a mulberry-like area consisting of small papillae, which is typical of and specific to VX, and the diagnosis were histologically confirmed in all cases. Dermoscopy revealed that each surface papilla contained linear or hairpin vessels, which were surrounded by a marginal whitish rim. These structures are thought to correspond to dilated vessels in dermal papillae and papillated acanthotic epidermis, respectively. Furthermore, observation under compression (similar to diascopy) revealed yellow dots and debris, reflecting lipid-laden foam cells. In order to compare these findings with those of other disorders with similar findings, two patients with xanthogranuloma, six with sebaceous naevus, and three with senile sebaceous hyperplasia were examined. The dermoscopic findings in these patients were not similar to those of VX. Therefore, we believe that the above dermoscopic findings are specific to VX and could be helpful in diagnosis.

“…Several cases of polypoid, polypous or pedunculated CCA have been reported in various locations, including the head and neck, nipple, scrotum and lower extremity [ 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 ]. ( Figure 8 ) We are reporting an additional case of polypoid CCA, which is also the second polypoid CCA reported on the neck.…”

Degos and Civatte first described clear cell acanthoma (CCA) in 1962 and later in a review article found that, in most instances, the lesion was a solitary red-brown dome-shaped papule that involved the distal lower extremity. The first morphologic variant of CCA was reported as a “giant form of the acanthoma of Degos” which measured 45 × 40 mm, about twice the size of the largest CCA documented earlier. Since then, many variants of CCA have been described, including polypoid, pigmented and atypical. Herein, we describe a new variant of CCA and add another example of the polypoid variant to the literature. The new variant exhibits cellular features of trichilemmoma but architecturally differs from it. We also attempt to broaden the list of CCA variants summarized by Tempark and Shwayder by adding ours and a few more examples of CCA. The new variants of CCA include verrucous, linear, subungual and trichilemmal.
