A. LEFT ORBITAL MASS BIOPSY: Fibrous tissue with pacinian-like hyalinized bands consistent with eosinophilic angiocentric fibrosis iwth pacinian-type features. B. LEFT NASOLACRIMAL LESION BIOPSY: Sinonasal mucosa. C. LEFT MAXILLARY BIOPSY: Eosinophilic angiocentric fibrosis with pacinian-type features (1.2 cm in aggregate). D. LEFT ORBITAL MASS: Eosinophilic angiocentric fibrosis with pacinian-type features (1.2 cm, in aggregate). Note: The lesion is benign, and will likely not recur. However, as it is received fragmented, clinical follow up is advised, as if some lesion left in situ, there is a possibility for local recurrence. Immunostains are pending and will be reported in an addendum. E. NASAL AND SINUS CONTENTS, LEFT: Eosinophilic angiocentric fibrosis with pacinian-type features, focal. Sinonasal papilloma, inverted type, early focus, 2 mm. Chronic rhinosinusitis with scattered eosinophils and focal allergic mucin (see note). Note: GMS (silver) stain to assess for fungus is being performed, and the results will be reported in an addendum. F. LEFT NASOLACRIMAL LESION: Eosinophilic angiocentric fibrosis with pacinian-type features, focal. G. LEFT MAXILLARY: Eosinophilic angiocentric fibrosis with pacinian-type features (2.1 cm, in aggregate). H. LEFT LACRIMAL SAC EXCISION:
Eosinophilic angiocentric fibrosis with pacinian-type features (1.0 cm, in aggregate).
