Cutaneous pseudolymphoma associated with molluscum contagiosum: a case report

We report an unusual case of molluscum contagiosum associated with pseudolymphoma in an otherwise healthy young woman. She presented with a 2-week history of a rapidly enlarging painful umbilicated nodule behind her right ear. With the clinical presentation suspicious for a tumoral lesion, we decided to remove it surgically. Histological examination showed a florid cellular infiltrate surrounding a typical lesion of molluscum contagiosum. The infiltrate was composed of small to large pleomorphic lymphocytes. However, clonal TCR rearrangement could not be demonstrated. As far as we know this is the first case where the clinical picture is shown.
