“…Desmoplastic SN also shows more prominent vascular proliferation in the deep dermis 4 . Such histologic findings correspond to type 1 SN among the four types of clinically classified SN and tend to be light-colored and soft 5 . They are frequently misdiagnosed as pyogenic granuloma or hemangioma.…”

“…6,7,20 The reports of widely metastasizing disease from lesions not histologically discernable from banal Spitz nevi [21][22][23] support this concept of a phenotypic continuum and underscore the point that the accurate diagnosis of melanoma with Spitzoid features can be problematic, even for the most experienced dermatopathologist.…”

A new device—the rotational particle separator (RPS)—is compared to the cyclone for the removal of ultrafine particles, such as cryogenically condensed contaminant droplets from natural gas. The comparison focusses on identifying for each configuration the smallest size of particle which has a 50% chance of being removed from the gas stream. Whereas a cyclone can only separate 1 μm droplets at very low‐throughputs on the order of 1 MMscfd, at the same energy consumption and device volume, the rotational particle separator removes droplets of that size at throughputs of 300 MMscfd. The advantage of the rotational particle separator, therefore, lies in its compact separation potential for full‐scale industrial gas well throughputs. © 2006 American Institute of Chemical Engineers AIChE J, 2007

“…[1][2][3][4][5][6][7][8] Later, Arthur C. Allen (1953) included juvenile melanoma in the category of benign melanocytic lesions due to its benign biological behavior, although it presented a cytoarchitecture that was similar to that of melanoma. [6][7][8][9][10] These two authors classified Spitz nevus as a distinct type of nevus.…”

Spitz and Reed nevi, also called spindle and/or epithelioid cell nevi, are a special group of melanocytic lesions due to their peculiar clinical, dermoscopic and histopathological features. The study of these nevi is of great interest because both their nomenclature and classification are still a matter of discussion. Most importantly, the difficulty to differentiate them from melanoma can lead to inadequate therapies. In this context, dermoscopy, a link between clinical and anatomopathological examinations, appears as a helpful diagnostic tool whose accuracy can reach 93%. "Borderline" lesions are still a great challenge and object of research, including molecular studies. The present study explores the relevant characteristics of these nevi, with emphasis on dermoscopic findings, aiming at understanding their natural history, as well as discussing treatment and patient follow-up. Keywords: Dermoscopy; Melanoma; Nevus, epithelioid and spindle cell Resumo: Os nevos de Spitz e de Reed, ou também chamados nevos de células fusiformes e/ou epitelióides, formam um grupo especial de lesões melanocíticas, por suas características peculiares, tanto clínicas como dermatoscópicas e histopatológicas. Torna-se grande o interesse no estudo desses nevos, pois tanto a nomenclatura como a classificação ainda são motivos de debate e, sobretudo, a dificuldade de diferenciação com o melanoma pode gerar condutas terapêuticas inadequadas. Neste contexto, surge a dermatoscopia, elo entre o exame clínico e o anatomopatológico, como método diagnóstico auxiliar importante cuja acurácia pode chegar a 93%. A grande dificuldade ainda são as lesões "borderline", motivo de pesquisas, incluindo estudos moleculares. O presente estudo aborda os aspectos relevantes das características destes nevos, com ênfase nos achados dermatoscópicos, buscando o entendimento da sua história natural, além da discussão quanto ao tratamento e seguimento dos pacientes.
