Cavity is lined by fibroblasts and histiocytes with presence of haemosiderin laden macrophages, inflammatory cells and multinucleate giant cells.34 Treatment consists of extended curettage and bone grafting with a bone graft substitute or cementing.
These were then evaluated for histopathological variables which included thickness of epithelial lining, keratinization, foamy macrophages, mucous cells, Rushton bodies, cholesterol crystals and haemosiderin. Chi-square test/ Fishers exact test was applied to compare cysts.
Occasional cells demonstrated intracytoplasmic vacuole formation, or intranuclear inclusions (Figure 1b), and focal cytoplasmic haemosiderin pigment mimicking melanin.
Neovascularisation and fibrosis with haemosiderin deposits were also found in close proximity to the transplanted islets.
MRI imaging usually shows mass-like proliferation of the synovium with lobulated margins, either diffuse or localized, along with low-intensity signals due to haemosiderin deposition.
Special stains, Methyl green-pyronin (MGP) for calcium deposition and pearl blue reaction for haemosiderin pigments were employed where necessary.
Over time, the haemorrhage is fully resorbed leaving behind iridescent spots of haemosiderin and macrophage deposition at the level of the internal limiting membrane.
The absence of normal pancreatic tissue and increased attenuation of the liver possibly due to haemosiderin deposition are also evident.
These lesions derive their name from the colour of the tissue specimen, which is usually dark red-brown because of the abundant haemorrhaging and haemosiderin deposits within the tumor.
