A rare presentation of an ACTH-producing high grade large cell
neuroendocrine carcinoma with Cushing's syndrome
Large cell neuroendocrine carcinoma (LCNEC) was first proposed by Travis
et al. in 1991 and subsequently classified as high grade neuroendocrine
carcinoma (HGNEC) by the world health organization. It is a rare tumor
with unclear clinicopathologic features. Herein, we describe a rare case
of LCNEC with a unique Cushing’s presentation.
