Small cell carcinoma of the bladder is a rare, aggressive, poorly differentiated neuroendocrine neoplasm
accounting for only 0.3-0.7% of all bladder tumors.
Biopsies were consistent with rectal small-cell carcinoma characterized as a poorly differentiated neuroendocrine neoplasm
H&E staining demonstrated a neuroendocrine neoplasm
The histologic differential diagnosis of malignant melanoma of the esophagus is broad and includes lymphoma, poorly differentiated carcinoma (either squamous or adenocarcinoma), a high-grade neuroendocrine neoplasm
, and possibly a metastasis or direct extension of a primary tumor elsewhere.
In pancreatic endocrine tumors, curative resection improved the survival of many patients with non-functioning neuroendocrine neoplasm
of the pancreas.

The dyscohesive pattern of the tumor cells generated the differential considerations of a neuroendocrine neoplasm
, a lymphoproliferative disorder, and melanoma.
The biopsy specimen yielded what was initially interpreted as a neuroendocrine neoplasm
suggestive of a poorly differentiated neuroendocrine carcinoma of the larynx; staining revealed that the specimen was positive for cytokeratin, carcinoembryonic antigen, chromogranin, synaptophysin, and calcitonin.
