Abstract
AbstractObjectiveHaemoglobin spherulosis (HS) is a rare lesion occurring post‐vitreous haemorrhage that is absent from the cytopathology literature.MethodsWe present the fine needle aspiration (FNA) biopsy cytological features of a case of HS occurring in a 73‐year‐old woman.ResultsFNA smears of hemorrhagic vitreous fluid showed numerous variably sized smooth glassy spherules ranging from 3‐20 μm. Occasional red cells and a rare lymphocyte were observed, but other cell types were absent. Immunohistochemical staining of a cell block showed diffuse positive staining of spherules with haemoglobin A.ConclusionsHS is a rare lesion that occurs post‐subretinal haemorrhage and may be encountered by pathologists examining ocular cytological specimens.
