Abstract:

 


Mixed adenoneuroendocrine cancers are rare tumors. The
association of colonic tubulary adenomas with microcarcinoid tumors has been
reported very rarely in the literature. As known, the neuroendocrine component
in these tumors display a broad spectrum with marked variability in histopathology
properties; such as glandular pattern, spindle cell pattern, squamous-osteoid
metaplasia or pleomorphism. Rarely, they may be very poorly differentiated and
may resemble undifferentiated carcinoma or lymphoma. In addition,
immunohistochemical analysis of carcinoid tumors associated with some syndromes
such as Zollinger-Ellison and carcinoid has shown that, most are multihormonal
as well as one amine or peptide may predominate and the amines and peptides in
the primary tumor do not often match to those normally found in the overlying
endocrine cells. However, an increasing number of tumors have recently been
described including mixtures of neoplastic endocrine and non-endocrine
epithelial cells. Furthermore, there are different types of tumors in which endocrine
and epithelial cell characteristics are observed in the same cell. Similar to
all this literature information, morphological and immunohistochemical findings
in our case show that, the two neoplastic components originate from a common
precursor cell.
