Punctuate porokeratotic keratoderma

Spiny keratoderma: A review of case reports and histopathological descriptions

“…Of the 58 articles, 10 were case series, resulting in 84 SpK cases for analysis (Table 1). The individual cases were published in the USA (32), 1,3,8,9,12,16,18,20,24,[30][31][32][33][34]37,45,47,49,53 Spain (12), 14,22,23,26,28,29,36,39,50,54,58 Saudi Arabia (7), 10 Italy (6), 2,13,19,46,55 Japan (6), 11,21,25,40,52 Brazil (4), 5,42 United Kingdom (3), 41,57 Australia…”

Poroqueratosis punctata: reporte de un caso y revisión de la literatura

“…Friedmann comenta en 1988 que aún era necesaria una clasificación adecuada para estos casos [29]. El autor diferencia clínicamente las lesiones acuminadas, de tipo "caja musical", y las lesiones deprimidas, denominadas pits.…”

Unilateral Spiny Hyperkeratosis

“…There are no significant changes in the epidermis surrounding the spines, and the superficial dermis may show a slight mononuclear cell infiltrate. Several studies have shown different electron microscopy results [13, 19, 34]. …”

“…Many authors have pointed out that such keratinocyte changes do not exist under the cornoid lamella-like spines of SH[15, 19, 20, 22, 27, 33, 34]. Therefore, the labeling of SH as porokeratotic in some of the reports is misleading [2, 13, 16, 19, 26, 44]. It is important to differentiate SH from porokeratosis because the latter, unlike SH, is premalignant.…”
