“…1 in 1962. It is characterized by a reddish, dome‐shaped nodule that is covered with a thin crust, and it is sometimes accompanied by a small amount of exudate 2 . It often occurs as a solitary, slow‐growing nodule on the lower limbs that may persist for 2–30 years but can also be found on the trunk or face in individuals aged 50–70 years.…”

Clear cell acanthoma (CCA) is a rare benign epidermal tumor that is difficult to diagnose by visual inspection. Conversely, its diagnosis by dermoscopy is relatively easy owing to the characteristic serpiginous arrangement of coiled vessels, sometimes described as the "string-of-pearls" formation. However, in few published reports, the dermoscopic diagnosis of mature CCA has been reported. Here, we report the histopathological and detailed dermoscopic findings of two CCA cases. Between these, one case was of early (~6 months) CCA exhibiting the characteristic vascular string-of-pearls formation, whereas the other was of a more mature (~10 years) CCA; although the latter case showed combined thick and thin white intersecting lines with large coiled vessels and/or red clods, it had the string-of-pearls formation. Thus, regardless of CCA maturity, the string-of-pearls formation was present. We propose that the combination of combined thick and thin white intersecting lines along with the vascular string-of-pearls formation reflecting large coiled vessels and/or red clods on dermoscopy is a diagnostic clue to mature CCA.

“…In such cases, the term “eruptive” has been applied by the authors. Several cases of the eruptive variant have been reported [ 46 , 47 , 48 , 49 , 50 ]. The first of such cases was reported by Burg et al [ 46 ] as eruptive hamartomatous CCA in a 38-year-old female with over 100 lesions on her legs, arms, and trunk.…”

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.

“…No obstante, se han descrito localizaciones tan heterogéneas como la axila (Lever et al, 2015), primer dedo del pie (Wang & Chi, 2006), pezón (Nazzaro, 2014), el dorso de la mano (Cetinozman et al, 2016) e incluso en un injerto cutáneo , siendo nuestro caso el primero descrito en pared abdominal. Llama la atención la descripción de una veintena de casos de acantomas de células claras múltiples haciendo hincapié algunas de ellas la rápida progresión presentada por algunas de las lesiones (Monari et al, 2010;Rotaru et al, 2014;Martinez Escaname et al, 2015).También has sido descritas variantes "gigantes" del acantoma de células claras asociadas a tratamiento con infliximab en un paciente con psoriasis, sin transcendencia pronóstica (Cavicchini et al, 2015) e incluso se han descrito lesiones con la misma histología inducidas por un dermatofibroma en crecimiento (Silverstein & Marghoob, 2012).…”

Resumen: Introducción. El acantoma de células claras es una lesión tumoral benigna relativamente infrecuente que muestra unas características histológicas que permiten su diagnóstico. Método. Presentamos el caso de un acantoma de células claras abdominal, localización infrecuente, en un paciente de 72 años. Resultado. El diagnóstico fue establecido tras el pertinente estudio histológico pues la clínica inespecífica y la localización atípica impedían la realización de un correcto juicio clínico. Conclusiones. Pretendemos con la presentación del presente caso poner de manifiesto la histología tan peculiar de esta lesión al tiempo que, a través de una amplia revisión bibliográfica, mostramos distintas localizaciones y presentaciones atípicas de dicha entidad.
