eyelash elongation and acne are well-documented side effects of dermatology caused by the treatment of EGFR inhibitors.
it is believed that Pani monoantigen-induced eyelash elongation is the result of EGFR inhibition in the eyelashes.
if it develops into eyelash elongation, it is usually noticed in the first few months of treatment, just like in the patient.
the condition eases with the cessation of treatment, which usually requires treatment.
the patient was discharged from the hospital after non-surgical treatment of intestinal obstruction and continued to use Pani monoantigen.
