Macrophagic myofasciitis and aluminium-containing vaccines WHO (Visit this link)

The emergence of a new type of histopathological lesion of unknown origin called macrophagic myofasciitis (MMF), characterized by a unique myopathological pattern, has been reported.
MMF is characterized by centripetal infiltration of the epimysium, perimysium and perifascicular endomysium by non-periodic-acid-shiff (PAS) positive cells of macrophage lineage with osmiophilic crystal inclusions. MMF has been mainly detected by deltoid muscle biopsy in adult patients, although it has also been detected by quadriceps muscle biopsy in 3 young children. The histopathological lesion is localized at these sites.
