Ischaemic fasciitis: a very rare entity with unusual presentation.

We are reporting a case of ischaemic fasciitis which occurred in a 55-year-old female with no debilitating or long bed ridden history. She presented with a large swelling over left gluteal region. On evaluation, swelling was found to be of size, 5x5 cm, slightly tender and with induration. The operative findings led to a probable diagnosis of a calcified lesion, due to its hard consistency. However, the microscopic picture was typical of ischaemic fasciitis, because of its characteristic central necrosis, vascular and atypical fibroblastic proliferations. Also seen was presence of foreign body giant cell reactions, inflammatory cells and extravasated RBCs. Ischaemic fasciitis is a very rare pseudo sarcomatous proliferation of atypical fibroblasts, which has been described to be located over bony protuberances and said to develop most often in immobile elderly or debilitated patients. Recognition of this distinct entity as a reactive process, mostly associated with debilitation is rare in occurrence.
