Moluscum contagiosum on infundibular cyst. No more than a curiosity

Abstract

The infundibular cyst is a skin lesion typically located on hairy areas that is extremely common. In fact, it is part of the daily routine of any pathology laboratory. Although both the dermatologist, the surgeon and the pathologist are sufficiently familiar with it and guide each case correctly, sometimes there are histological peculiarities that justify the histological study of the lesion. The coincidence of a molluscum contagiosum, a highly contagious entity in the context of an infundibular cyst, implies taking a series of precautions that would not be implemented based solely on clinical criteria.
