English abstract

Seborrhoeic keratoses (SK) are benign tumors that mainly occur in the head and in the trunk. Their size generally varies from a few millimeters up to a few centimeters. Giant lesions are very rare but pose a problem in terms both of treatment and transformation. Their occurrence in the genital area is even more rare, posing a problem in differential diagnosis of genital warts. Differentiation is only based on histopathology. We report the case of a 80-year old man, with no particular past medical history, who presented with asymptomatic abdominal and genital lesions evolving over the last twenty years. Clinical examination showed four hyperpigmented, humped, well-defined tumors, with warty surface measuring 2-10 cm along its longer axis (A). Dermoscopic examination showed cerebriform convolutions appearance suggesting seborrhoeic keratoses (B). Histology confirmed the diagnosis, without signs of viral infection or malignant transformation. The patient underwent surgical resection resulting in permanent scar.

Key words: Giant seborrhoeic keratoses, unusual location

Les k�ratoses s�borrh�iques (KS) sont des tumeurs b�nignes qui si�gent �lectivement au niveau de la t�te et du tronc. Leur taille varie g�n�ralement de quelques millim�tres � quelques centim�tres. Les l�sions g�antes sont tr�s rares, posant un probl�me de prise en charge et de transformation, et leur emplacement sur la zone g�nitale est encore plus rare, posant un probl�me de diagnostic diff�rentiel avec les condylomes et dont la diff�renciation est faite uniquement sur l'histopathologie. Nous rapportons le cas d�un homme de 80 ans, sans ant�c�dents pathologiques particuliers, qui consultait pour des l�sions abdominales et g�nitales asymptomatiques �voluant depuis vingt ans. L�examen clinique trouvait quatre tumeurs hyperpigment�es en relief, bien limit�es, � surface verruqueuse mesurant entre 2 et 10 cm de grand axe (A). L�examen dermoscopique objectivait un aspect de circonvolutions c�r�briformes, �voquant des k�ratoses s�borrh�iques (B). L�histologie avait confirm� le diagnostic sans objectiver de signes d�infection virale ni de transformation maligne. Un traitement par ex�r�se chirurgicale �tait entrepris au prix d�une cicatrice ind�l�bile.
