[Dermatitis caused by the manchineel tree].

Contact dermatitis form Hippomane mancinella L. (manchineel) is commonly observed in Caribbean and Central American Coast land. Its sap from leaf exudate and from the fruit induce severe dermatitis that may involve oral, ocular, genital mucous membranes and skin, depending on the mediate or direct type of contact. Intense itching or burning sensation occurs within an hour and is followed by painful erythema, vesicles, bullae or pustulae, the latter being highly suggestive of mancheneel. Oropharyngeal and ocular lesions may by very severe. The brief delay and the burnlike appearance of the lesions suggest an orthoergic mechanism due to a caustic that could be similar to the substance identified in an other species of Euphorbiacae as phorbol esters. Traditional and native remedies are presented herein.

[Leprosy in young children. 2 cases at 3 years of age].

Two children (age 3 years) presented with leprosy in endemic area: one was type T (tuberculoid paucibacillary); the other was type BL (borderline lepromatous) considering a very fast evolution, and was treated as a multibacillary leprosy. The family of the second child reported that the onset of the disease was consecutive to an insect bite at 5 1/2 months of age. Such observations remind us that leprosy must be suspected or thought about very early since the incubation period is likely to be shorter than previously proclaimed.
