Syphilis, leprosy, and human immunodeficiency virus coinfection: a challenging diagnosis.

The association between syphilis, leprosy, and human immunodeficiency virus (HIV) is not well documented, and the emergence of isolated cases raises the interest and indicates that this triple coinfection can occur. We report the case of a 42-year-old man from Rio de Janeiro, Brazil, who presented with erythematous papules on the trunk, back, and upper and lower extremities; an erythematous plaque on the upper abdomen; and an erythematous violaceous plaque on the right thigh with altered sensitivity. Laboratory investigation showed a reagent VDRL test (1:512) and positive test results for Treponema pallidum hemagglutination.

Cutaneous manifestations of Prader-Willi syndrome.

Prader-Willi syndrome (PWS) is a multisystemic genetic disease associated with structural, behavioral, and intellectual disorders. The clinical appearance of PWS includes dysmorphic facial features with almond-shaped eyes, a narrow bifrontal diameter, and a thin upper lip; short stature; central obesity; and small hands and feet. We present a case of a 27-year-old woman with PWS and describe the typical clinical features and cutaneous manifestations of PWS.

Case for diagnosis. Acrokeratoelastoidosis.

Acrokeratoelastoidosis is a type of palmoplantar keratoderma first described by Oswaldo Gonçalves Costa, a Brazilian Dermatologist from the state of Minas Gerais. It is a rare autosomal-dominant genodermatosis; however it may occur sporadically. The disease is not congenital; rather, its onset occurs in childhood or adolescence.

Elaioconiosis--case report.

Elaioconiosis is a work-related acneiform dermatosis which affects the exposed skin of individuals working with oils or greases. Its incidence has decreased with the introduction of personal protective equipment, personal hygiene measures and the cleaning of work clothes. Although not a rare disease, elaioconiosis is seldom reported in the literature, particularly in Brazil.

Sexually transmitted diseases during pregnancy: a synthesis of particularities.

Sexually transmitted diseases (STDs) have a significant prevalence in both the general population and pregnant women. Accordingly, we consider the physiological changes of the maternal organism that can alter the clinical course of these diseases. In addition, obstetric and neonatal complications may occur, resulting in increased maternal and infant morbidity and mortality.
