The Koebner phenomenon has been reported to develop in classic or acquired
immune deficiency syndrome-related Kaposi's sarcoma (KS). A 12-year-old kid
ney transplant recipient who developed immunosuppression-related KS showed
reoccurrence of lesions in some previously intact incision sites following
removal of tumor, suggesting Koebner phenomenon. It is recommended that sur
geons be careful when planning surgical interventions in patients with cert
ain skin disorders in which Koebner phenomenon is known to develop.
