Lobar pneumonia is a form of pneumonia characterized by inflammatory exudate within the intra-alveolar space resulting in consolidation that affects a large and continuous area of the lobe of a lung. [1] [2] It is one of three anatomic classifications of pneumonia (the other being bronchopneumonia and atypical pneumonia).
Atypical hyperplasia is a high-risk premalignant lesion of the breast. It is believed that atypical ductal hyperplasia (ADH) is a direct precursor for low-grade mammary ductal carcinoma , whereas atypical lobular hyperplasia (ALH) serves as a risk indicator.
Necrotizing pneumonia (NP), also known as cavitary pneumonia or cavitatory necrosis, is a rare but severe complication of lung parenchymal infection. [ 5 ] [ 6 ] [ 7 ] In necrotizing pneumonia, there is a substantial liquefaction following death of the lung tissue, which may lead to gangrene formation in the lung.

Like the cells of atypical lobular hyperplasia and invasive lobular carcinoma, the abnormal cells of LCIS consist of small cells with oval or round nuclei and small nucleoli detached from each other. [12] Mucin-containing signet-ring cells are commonly seen. LCIS generally leaves the underlying architecture intact and recognisable as lobules.
There are two types of atypical hyperplasia: lobular and ductal; the lobular type is associated a greater cancer risk of approximately five-fold and especially high relative risk in premenopausal women. Atypical ductal hyperplasia is associated with a 2.4-fold risk. [20]
