A 33-year-old African woman was evaluated for tender nodules on her fe
et. Accompanied by her four children, she had recently immigrated from
Somalia. Before her immigration, she resided in a Kenyan refugee camp
for approximately 1 year, where she walked barefoot in sand and dirt.
The patient stated that she and her four children, as well as many pe
ople living in the same compound, had similar, tender lesions on their
feet. Her children were ''treated'' by their grandmother, who removed
the contents of their lesions with a safety pin. On physical examinat
ion the patient had numerous tender, isolated, and clustered hyperkera
totic, crusted papules, measuring 4-6 mm, on the plantar and periungua
l surfaces. Several lesions were ulcerated (Figs 1 and 2). The hyperke
ratotic masses were debrided with a surgical blade. An intact, white,
coiled structure was curetted from each papule, leaving numerous empty
crater-like lesions (Fig. 3), which were identified on histologic sec
tions as Tunga penetrans. Microscopic examination of unstained specime
ns showed branching, thin, translucent tubular structures with numerou
s eggs. Ring-shaped cross-sections of the organism's respiratory and d
igestive tracts were seen on hematoxylin and eosin stain (Fig. 4). The
patient received a 10-day course of dicloxacillin and topical bacitra
cin ointment. All lesions were healed within 1 week of therapy.
