Neoplasms of bronchus commonly designated as adenomas

Papillary Neoplasms of the Bronchus of Low-grade Malignancy.

In this paper we describe eight examples of papillary neoplasms of the bronchus in which atypical cytological features were present. In seven the lesion was localized and invasion was not present, in one extensive spread within the bronchial tree of a lobe had occurred but invasion into the lung parenchyma was doubtful. Lesions of this type receive little comment in the literature although they...

Carcinoma of bronchus presenting as hydropneumothorax.

Fig. 1 : Right sided hydropneumothorax, with collapse (Black arrow head): Before fluid aspiration Fig. 2: After drainage Black Arrow Head: Right side air bronchogram, in the middle lobe. White ArrowHead: Encysted pneumothorax in lower zone. lung cancer is one of the common malignancies encountered in daily practice, but its presentation as hydropneumothorax is rare. We report a 50 year old male...

Carcinoma of the bronchus presenting as a cerebellar neuropathy.

THE protean manifestations of carcinoma of the bronchus are becoming increasingly recognized, and amongst the most interesting are the various neuropathies which may be encountered. These neurological syndromes, occurring independently of secondary deposits, are classified by Brain and Henson (1958) as cortical cerebellar degeneration, mixed forms, sensory neuropathy, peripheral neuropathy (sen...

Plk2 Loss Commonly Occurs in Colorectal Carcinomas but not Adenomas: Relationship to mTOR Signaling

Plk2 is a target of p53. Our previous studies demonstrated that with wild-type p53, Plk2 impacts mTOR signaling in the same manner as TSC1, and Plk2-deficient tumors grew larger than control. Other investigators have demonstrated that Plk2 phosphorylates mutant p53 in a positive feedback loop. We investigated Plk2's tumor suppressor functions in relationship to mTOR signaling. Archival specimen...
