Résumé
A chromosome study was carried out on a number of European and Central Asiatic diploid green toad populations by means of standard and various other chromosome banding and staining methods (Ag-NOR-, Q-, CMA3-, late replicating [LR] banding pattern, C-and sequential C-banding + CMA3 + DAPI). This study revealed the remarkable karyological uniformity of specimens from all populations, with the only exception being specimens from a Moldavian population, where one chromosome pair was heteromorphic. Though similar in shape, size and with an identical heterochromatin distribution,the difference in the heteromorphic pair was due to a large inverted segment on its long arms. This heteromorphism was restricted to females, suggesting a female heterogametic sex chromosome system of ZZ/ZW type at a very early step of differentiation.

Se caracteriza por pápulas y nódulos erityematosos, dolorosos, localizados en plantas y excepcionalmente en palmas. Presentamos los tres primeros pacientes pediátricos de nuestro medio con hallazgos clínico patplógico de hidradenitis palmoplantar recurrente idiopática.
