Fever and Multiple Eschars After an African Safari: Report of Three Cases.

African tick-bite fever (ATBF), a tickborne disease endemic in rural areas of sub-Saharan Africa and the West Indies caused by Rickettsia africae, has been recognized as an emerging health problem in recent years. ATBF has been reported as the second most commonly documented etiology of fever, after malaria, in travelers who return ill from sub-Saharan Africa.

Trichodysplasia Spinulosa in a 20-Month-Old Girl With a Good Response to Topical Cidofovir 1%.

Trichodysplasia spinulosa (TS) is a rare entity, characterized by a follicular digitate keratosis predominantly affecting the face and variable degrees of hair loss, most severely facial hair, that occurs in immunosuppressed individuals, and is considered to be a viral infection caused by a human polyomavirus, the "TS-associated polyomavirus." Histologically it is characterized by hair follicles with excessive inner root-sheath differentiation and intraepithelial viral inclusions. Correlation of these findings with clinical features is required for diagnosis.
