Invertebrates such as snails which mostly have a shell. Includes the octopus.
Common papular eruption of the skin caused by a virus. Most common in children, it is highly contagious and often transmitted in swimming pools and sauna baths. Mollusca are often multiple and persistent in children with atopic eczema (see DERMATITIS), and epidemics may occur in boarding schools. The typical molluscum is 2–3 mm in diameter, skincoloured and translucent, with a dimpled centre. The armpits and adjacent chest, upper inner thighs and genital areas are common sites in young children. In adults the infection is usually transmitted sexually and affects the pubic area and lower belly. Mollusca eventually disappear spontaneously, but cure can be expedited by curettage (removal with a CURETTE) under surface anaesthesia.... molluscum contagiosum
