Careful consideration must be given to the possibility of occult neoplasms in dermatomyositis in middle-aged to elderly patients.3,8,9 The most common cancers found in association with dermatomyositis are ovarian, pancreatic, and lung cancers. We have presented a case of dermatomyositis associated with cancer of the lung and presenting livedo reticulated ulcers due to livedoid vasculopathy. We ...

Sclerosing hemangiomas of the lung are benign neoplasms of uncertain histogenesis. We analysed two cases of sclerosing hemangiomas of the lung with histochemistry and electron microscopy. They had a variegated histologic appearance characterized by an admixture of solid, hemorrhagic, papillary and sclerotic lesions. Characteristic uniform round cells, unique to this tumor, were found within the...

Atypical alveolar hyperplasia (AAH) is a potential precursor lesion from which lung adenocarcinomas arise and may be a good target for studying the early events of lung tumorigenesis. A common genetic alteration in lung adenocarcinomas is mutational activation of K-ras. To determine the timing of K-ras activation, we evaluated formalin-fixed and paraffin-embedded tissue samples of 41 AAHs and t...
