President of prewar Lvov and Polish Republic on Exile, associate professor Stanisław Ostrowski was a dermatologist with a keen interest in dermatopathology. This study was based on original resources, which – mainly reports of his own authorship – were focused on dermatopathology. Stanisław Ostrowski provided excellent description of naevus epitheliomatosus sebaceus Wolters-Friboes both in Polish and German to be cited after decades in renowned handbooks of dermatopahtology published by Springer Verlag. His scientific output also includes meticulous presentation of Fox-Fordyce disease (apocrine miliaria) as well as gold-induced skin changes to Polish readership. Thus, this study documents dermatopahtological achievements of Stanisław Ostrowski – the unifying statesman of society of Lvov and Polish emigration in London.
