A young male presented with complaints of painless swelling over the sac area in right eye since 3 months. Mass excision with Dacryocystectomy was performed which showed friable red mass suspicious of Rhinosporidiosis of lacrimal sac which on histopathological evaluation showed tumour tissue spindle cells in fascicles,interspersed chronic inflammatory cells,vascular proliferation,areas of hemorrhage and fibrosis suggestive of Angiomatoid fibrous histiocytoma (Intermediate grade).A young male presented with complaints of painless swelling over the sac area in right eye since 3 months.
