Oncocytic carcinoid of the lung

Abstract

An U It ras t ru c t u ra I An a I ysis DANIEL SCHARIFKER, MD, AND ALBERT0 MARCHEVSKY, MD A 52-year-old man with a typical carcinoid tumor of the lung in which the tumor cells displayed marked oncocytic metaplasia is presented. The clinicopathologic and ultrastructural differences with so-called oncocytic of the lung are discussed. The potential of Kulchitsky cell derivatives to undergo oncocytic metaplasma is documented ultrastructurally. Cancer 47530-532, 1981. ARCINOIDS OF THE BRONCHUS were first described C in the last quarter of the nineteenth century.12

Growth of a solitary pulmonary nodule after 6 years diagnosed as oncocytic carcinoid tumour with a high 18‐fluorodeoxyglucose (18F‐FDG) uptake in positron emission tomography‐computed tomography (PET‐CT)

“…There was no electron microscopic examination in our case. But, it has been reported that immunohistochemical positivity does not have to be specific for this diagnosis (11) unless oncocytic changes are thought to depend on a high number of mitochondria in the cell cytoplasm (16).…”

Oncocytic neuroendocrine tumors of the lung: histopathologic spectrum and immunohistochemical analysis of 15 cases

“…Oncocytic carcinoid tumors have been reported in the nasopharynx [5], thymus [6], lung, pancreas [7], kidney [8], and urinary bladder [9]. Oncocytic carcinoid tumor of the lung has been reported in 11 single-case reports [10][11][12][13][14][15][16][17][18][19][20] and 1 case in a series analysis of carcinoid tumors [3].…”
