Molluscum contagiosum (MC) is a skin infection caused by the double-stranded DNA virus of the family Poxviridae that typically presents as flesh-colored asymptomatic umbilicated papules. Plantar MC is uncommon. We describe a 23-year-old man who presented with multiple plantar MC. We also summarize the epidemiologic features of the 34 previously reported patients with plantar MC and discuss the clinical characteristics, differential diagnosis, and treatment of plantar MC. The patients were immunocompetent and the median age at diagnosis was 21 years. Although the plantar MC were asymptomatic in some individuals, a common presenting symptom was pain while walking. Patients had 1 lesion (23/35), 2 lesions (5/35), 3 lesions (4/35), or more than 5 lesions (3/35). Giant MC (>or=1 cm in diameter) was observed in more than 75% (a minimum of 27/35) of patients. At the initial patient evaluation, plantar verruca often was suspected; subsequently, light and/or electron microscopy of the plantar lesion confirmed the diagnosis of plantar MC. Removal or destruction of the lesion resulted in definitive treatment of the plantar MC.

    ABSTRACT: Molluscum contagiosum is a common cutaneous infection caused by a double-stranded DNA poxvirus. Skin lesions classically present as small, flesh-colored papules with central umbilication. Lesions are frequently seen on the face, trunk, and extremities of children, or on the genitals of young adults as a sexually transmitted infection. Molluscum contagiosum on the nipple or areola has only been previously described in 4 women. We describe a woman with molluscum contagiosum on the left areola and review the clinical characteristics and histological findings of patients who developed molluscum contagiosum of the nipple or areola.

    ABSTRACT: Chancroid, lymphogranuloma venereum, and granuloma inguinale may be considered as tropical venereal diseases. These diseases were a major diagnostic and therapeutic challenge in past centuries. Currently, patients with these bacterial infections that are endemic to the tropics occasionally consult with dermatologists in temperate climates. Due to the increasing frequency of travel to the tropics for tourism and work, as well as the increasing number of immigrants from these areas, it is important for dermatologists practicing in temperate climates to be familiar with the dermatologic manifestations of such infections, to be prepared to diagnose these diseases, and to treat these patients. All three "tropical" infections respond well to prompt and appropriate antimicrobial treatment, although herpes progenitalis still cannot be cured, and the number of people infected keeps growing; moreover, genital herpes can be transmitted by viral shedding before and after the visual signs or symptoms. Acyclovir, valacyclovir, and famciclovir can shorten outbreaks and make them less severe or even stop them from happening. There is currently no etiologic treatment for molluscum contagiosum, and the majority of treatment options are mechanical, causing a certain degree of discomfort. The molluscum contagiosum virus, unlike the other infectious agents mentioned, does not invade the skin.
