Notification of an adverse effect to human albumin 99MTc nanocolloid
Abstract Allergic reactions to albumin nanocolloid (NA) are rare. Most of them are not potentially serious and in some cases treatment with antihistaminics may be needed. We present a case of a patient with grade II right breast ductal carcinoma, in whom a lymphoscintigraphy was performed for sentinel lymph node detection. She had a type I hypersensitivity reaction following the administration of 99mTc albumin nanocolloid, which abated spontaneously without subsequent sequels.
