Molluscum Contagiosum in a Red Kangaroo

Natural infection of a red kangaroo (Megaleia rufa) with molluscum contagiosum pox-virus is reported. Large lesions up to 2 cm diameter were present on the back, elbow and lip. Histopathology and electron-microscopy confirmed that the disease was identical to human molluscum contagiosum.     

Central Pitting of Molluscum Contagiosum

Histological examination of 42 early lesions of molluscum contagiosum was performed. At the top of the molluscum papule, the epidermis cylindrically hung down into the dermis, thus forming an epidermal cylinder with a narrow canal. Acanthomatous change occurred at the bottom of the epidermal cylinder. Thirteen of the 42 molluscum lesions showed a direct connection with components of hair follicle. It is suggested that the central pitting of molluscum contagiosum may be the ostium of pilar infundibulum.     

Solitary Giant Molluscum Contagiosum of the Sole

Abstract: Molluscum contagiosum of the sole is extremely rare and only three cases have been reported in the literature. We report a solitary giant molluscum contagiosum on the left sole of a 5-year-old boy, which should be clinically differentiated from plantar wart, eccrine poroma, epidermal cyst, foreign body granuloma, cryptococcal infection, and pyogenic granuloma.

Staphylococcus lugdunensis Abscesses Complicating Molluscum Contagiosum in Two Children

We report the occurrence of Staphylococcus lugdunensis abscesses in two girls with molluscum contagiosum who both required surgical intervention under general anaesthesia. S. lugdunensis is a coagulase‐negative Staphylococcus recently recognized as an emerging human pathogen. Because of its ubiquitous nature and the high prevalence of molluscum contagiosum in children, it is likely that this as yet unreported association may be underestimated, thus raising the question as to whether bacterial culture of superinfected mollusca should be obtained more often.     

Treatment of Facial Molluscum Contagiosum with Trichloroacetic Acid

Abstract:   Molluscum contagiosum (MC) virus is a common cutaneous infection in the pediatric population, most commonly affecting school-aged children. Spontaneous clearing of lesions usually occurs over time; however, treatment is often sought due to cosmetic significance, pruritus, or concerns of transmission and autoinoculation. Chemical destruction with cantharidin, which is derived from blister beetle extract, is very safe and highly effective, making it the treatment of choice in the pediatric population. However, treatment of facial lesions or those in the diaper area are not recommended with this agent. Trichloroacetic acid is a safe and effective agent frequently utilized in dermatologic practice, most commonly in the treatment of verrucae. We have successfully used topical trichloroacetic acid to treat facial molluscum contagiousum and present the following technique for proper application.     

传染性软疣682例临床分析

目的 探讨传染性软疣发病的相关因素。方法 对682例传染性软疣的临床资料进行分析。结果 发病年龄在14岁以下者435例;儿童患者皮损以面颈部(43.5％)、四肢(52.9％)多见;成人患者以下腹部、外阴及生殖器常见;有明确传播途径者302例,其中家庭传播139例,公共场所传播112例,性传播51例。结论 传染性软疣多见于儿童及青少年,直接接触为主要传播途径。     

传染性软疣的临床与细胞学研究

对107例传染性软疣进行临床分析,测定了10例疣体的上皮细胞DNA含量,并对1例皮损作透射电镜观察。结果表明10例皮损表皮细胞核的DNA含量均为二倍体,而增殖指数较正常对照高。电镜下,传染性软疣的细胞核呈现空泡化,细胞浆内有大量病毒颗粒,这是本病易于传染的主要原因。     

Linear Congenital Molluscum Contagiosum on the Coccygeal Region

Congenital molluscum contagiosum is rare but has been reported previously. We present a unique case of linear congenital molluscum on the coccygeal region. To make a correct diagnosis, avoid unnecessary examination, and start appropriate treatment as soon as possible, it is beneficial for dermatologists to be aware that molluscum contagiosum can present at birth and can be linear.
