Only those who dare to fail greatly can ever achieve greatly. -Robert F. Kennedy Welcome back to RoshCast for Episode 46! Let’s kick off this episode with a rapid review of molluscum contagiosum. * Molloscum contagiosum is caused by poxvirus. It is seen in children, sexually active adults, and immunocompromised patients like those with HIV. The rash presents as painless, pearly, umbilicate papules, and it is spread by direct skin-to-skin contact. Children present with lesions on the face, trunk, and extremities, whereas sexually active adults can present with lesions in the genital regions, lower abdomen, and thighs. The rash tends to spare the palms and soles. Most patient will not require therapy with spontaneous resolution occurring in months. Those with extensive lesions may benefit from cryotherapy. HIV positive patients with a CD4 count less than 100 are at greater risk for developing molluscum contagiosum.
