A case of breast carcinoma with neuroendocrine features occurring in an elderly male patient is reported. Histologically, the tumor was characterized by solid growth with nests and ribbons of small to medium-size uniform neoplastic cells. Argyrophilia, expression of chromogranins at both protein and gene level, and the presence of dense granules of the neurosecretory type by electron microscopy were demonstrated.

Senile depression (SD) is a heterogeneous syndrome. Several clinical profiles are more likely to appear in SD than in early-life depression, but it remains unclear whether the pathophysiology is different. The prevalence of dementia increases with aging, and the underlying pathophysiological processes in the preclinical phase begin even before cognitive deficits or neurological signs appear.

Introduction And Importance: To describe an unusual case with a primary hepatic neuroendocrine tumour (PHNET) with multiple liver metastases.
Case Presentation: We reported a 65-year-old woman with PHNET with multiple liver metastases. She was highly suspected of having primary liver cancer with multiple intrahepatic metastases before liver biopsy, but was diagnosed with PHNET with multiple liver metastases after histopathology and immunohistochemistry (IHC) examinations.

Merkel cells (MCs) are neuroendocrine cells involved with tactile sense, growth, differentiation, and homeostasis of the skin as well as in different cutaneous diseases. Specific staining techniques are required for their identification because they are not easily visible in paraffin sections stained with hematoxylin and eosin. The present study assess the histochemical features of the MCs in dogs comparing with those described for other mammals in the literature and with the use of immunohistochemistry.
