Disseminated and disfiguring molluscum contagiosum in a child

We report widely disseminated and disfiguring lesions of molluscum contagiosum occurring in a 4-year-old girl secondary to a primary immunodeficiency disorder. The child, born of consanguineous parents, had multiple, asymptomatic, raised, skin-colored and whitish lesions since 2 years of age. On physical examination she had growth retardation features with grade II protein energy malnutrition. Cutaneous examination revealed numerous, widespread, skin-colored to translucent, firm, umbilicated papules of varying sizes (pinpoint to larger than 10 mm). They were distributed bilaterally over all four limbs, including the dorsum of the hands and feet, trunk, face (including lips), eyelids, auriculae, and perineal and gluteal areas. In places, they were linearly disposed and had coalesced to form plaques. A biopsy specimen from a representative skin lesion (arm) demonstrated lobulated epidermal growth consisting of keratinocytes with large intracytoplasmic eosinophilic inclusion bodies and a central crater. These findings were consistent with the diagnosis of molluscum contagiosum. Topical therapies with phenol and trichloroacetic acid were ineffective The child succumbed to a fulminant systemic infection at home, 2 months after discharge from the hospital. The extent and distribution of molluscum contagiosum in our patient was remarkably vivid and has been hitherto reported only rarely.
