Multifocal fixed drug eruption probably induced by mefenamic acid.

TNPM presents as subcorneal or intraepidermal pustules composed mainly of neutrophils; this finding helps to differentiate TNPM from NTE, in which there is a predominance of eosinophils. In conclusion, we must be aware that TNPM is a benign condition with no systemic manifestations and it does not require treatment. This entity can be confused with serious infections, and patients with TNPM may be administered empirical antibiotic treatment or undergo invasive tests. It is essential that pediatricians and dermatologists are aware of TNPM in order to avoid unnecessary additional tests or treatments.
