Mossy-like papillomata and block-shaped toes involving both feet were apparent, and the swelling had the consistency of a “water-bag” (<xref rid="fig1" ref-type="fig">Figure 1</xref><fig id="fig1" position="float"><label>Figure 1.</label><caption><p>Initial presentation of podoconiosis with bilateral “water bag” edema and block-shaped toes.</p></caption><graphic xlink:href="tropmed-95-1-g001"></graphic></fig>). The patient denied travel to Tanzania's coastal region. The symptoms of elephantiasis in the absence of exposure to areas where the mosquito vector for <italic>Wuchereria bancrofti</italic> is found make lymphatic filariasis unlikely and suggest podoconiosis.</p><p>Podoconiosis is known as “mossy-foot” because the papillomata have a moss-like appearance. It is caused by long-term barefoot exposure to volcanic soils high in silica. These soils are found in the highlands of tropical Africa, Central America, and northwest India.<xref rid="ref1" ref-type="bibr">1</xref> Seasonally heavy rains in these regions lead to soil erosion. Chronic, recurrent barefoot exposure to exposed silica leads to lymphatic obstruction resulting in ascending lymphedema.<xref rid="ref2" ref-type="bibr">2</xref></p><p>Podoconiosis is clinically distinguished from filarial elephantiasis. Unlike filarial elephantiasis, podoconiosis characteristically presents with block-shaped toes, mossy-like papillomata, and an ascending edema that stops at the knee without groin involvement (<xref rid="fig2" ref-type="fig">Figure 2</xref><fig id="fig2" position="float"><label>Figure 2.</label><caption><p>Podoconiosis with bilateral “water bag” edema. Note that the swelling terminates at the level of the knee joint.</p></caption><graphic xlink:href="tropmed-95-1-g002"></graphic></fig>). It is important to recognize that the presentation of podoconiosis can vary from the classic hard, nodular edema to a soft “water-bag” edema.<xref rid="ref1" ref-type="bibr">1</xref></p><p>Podoconiosis is preventable with consistent shoe wearing and good foot hygiene practices. Treatment includes use of compression bandages and elevation of the affected limbs.<xref rid="ref3" ref-type="bibr">3</xref> With time and proper treatment the edema and moss-like papillomata can diminish (<xref rid="fig2" ref-type="fig">Figure 2</xref>).</p></body><back><fn-group><fn id="FN1" fn-type="present-address"><p>Authors' addresses: Ryan Eid and Dhruv Sharma, Department of Medicine, University of Louisville School of Medicine, Louisville, KY, E-mails: <email>r0eid001@louisville.edu</email> and <email>d0shar05@louisville.edu</email>.
