Granulomatosis with polyangiitis (or formerly known as Wegeners granulomatosis) is a necrotizing granulomatous vasculitis which is characterized by necrotizing granulomatous inflammation, small and medium-sized vessel vasculitis, and focal necrotizing glomerulonephritis. As its name implies, it is reactive in nature. However, lipogranulomata can form a nodular mass lesion in isolation, without a co-existing meibomian gland tumor, Histologically the lipogranuloma surrounds the non-neoplastic meibomian gland, It is postulated that the granuloma reflects a reaction to release of meibomian lipid within the tissues. Keratin. Lymph node infarction is known to occur in association with many non-neoplastic and neoplastic conditions however its occurrence in association with DIC is not reported hitherto in the literature. PCR is useful in confirming a diagnosis in patients with clinical and/or pathologic features suggestive of Whipple disease.
