The pine caterpillar Thaumatopoea wilkinsoni is found in pine woods all ove
r Israel. Contact with its hair usually results in local reactions. Systemi
c reactions after contact with caterpillar hairs are known in other caterpi
llar species, but have been described only once after contact with T. wilki
nsoni. We describe a group of adolescents who were exposed to T. wilkinsoni
while camping in a pine wood. Three of them were referred to an emergency
department, They had severe pruritus, pain and edema at the contact sites,
with papular and urticarial rashes. Two of the patients had abdominal pain
and one patient had hypertension for several hours. The hypertension resolv
ed spontaneously. Conclusion: Skin eruptions are the most common manifestat
ions of T. wilkinsoni contact, however, although systemic manifestations ar
e rare, abdominal pain and hypertension may occur. (C) 1999 Elsevier Scienc
