Acne fulminans is a rare form of acne vulgaris of acute onset, affecti
ng mostly teenage boys and associated with a number of systemic sympto
ms and abnormal investigations. The occurrence of bone lesions in this
condition is rare but well recognized, and often bone biopsies are pe
rformed to rule out malignancy or infection. We report a 13-year-old b
oy referred to the pediatric oncologists with multiple osteolytic bone
lesions. He was noted to have severe acne. A potentially painful ster
nal bone biopsy was averted following dermatologic referral when a dia
gnosis of acne fulminans was made. Pediatricians and dermatologists ne
ed to be aware of this association so that unnecessary anguish and inv
estigations can be avoided.
