Small cell lung carcinoma

Small cell lung carcinoma is an aggressive, high-grade neuroendocrine malignancy that originates primarily in the respiratory epithelium of the bronchial tree Histologically and clinically, it is characterized by sheets of small, poorly differentiated cells with scant cytoplasm, granular nuclear chromatin, extensive necrosis, and a marked propensity for early hematogenous dissemination and paraneoplastic manifestations

It predominantly affects adults with a heavy history of tobacco exposure, accounting for approximately 15% of all pulmonary malignancies Pathophysiologically, it is defined by near-universal functional inactivation of tumor suppressor genes TP53 and RB1, rapid tumor doubling time, high mitotic activity, and widespread neuroendocrine differentiation Histologically and clinically, it is characterized by sheets of small, poorly differentiated cells with scant cytoplasm, granular nuclear chromatin, ...
