Clinical profile of molluscum contagiosum in children versus adults

Abstract

Molluscum contagiosum mainly affects children, but in adults the advent of HIV has modified its clinical spectrum. Our study is designed to ascertain the clinical profile of molluscum contagiosum in children and adults and to discover the effects of underlying HIV infection. During the study period of September 2000 to June 2002, 150 cases of molluscum contagiosum are screened and recruited at the Department of Dermatology and STD, JIPMER, Pondicherry. These include 137 children (85 male, 52 female) and 13 adults (10 male, 3 female). In children molluscum contagiosum is most commonly seen in the 5-10-year age group (58 cases), followed by the 1-5-year age group (53 cases), the 10-14-year age group (23 cases), and the younger-than-1-year age group (3 cases). In adults molluscum contagiosum is most commonly seen in the 14-20-year age group, followed by 2 cases each in the age groups 20-26 years, 26-34 years, and 34-40 years. The male-to-female sex ratio was 1.6:1 in children and 3.3:1 in adults. In both children and adults the most common sites affected are the head and neck, followed by trunk, upper extremity, genitalia, and lower extremity. It appears that the distribution of molluscum in our patients is significantly affected by the high proportion of HIV-positive adults in our sample. Seropositivity for HIV by ELISA is found in 1 of 137 children and 8 of 13 adults. In these HIV-positive patients, 2 cases of giant molluscum and one furuncle-like presentation are seen.
