Primary neuroendocrine carcinoma (PNEC) of breast was an unknown pathologic entity till recently due its rare incidence and lack of definitive criteria for diagnosis. We present a case of PNEC of breast in a middle aged lady. A 34 years lady presented with a breast lump since 1 month, who underwent modified radical mastectomy with axillary clearance. Histopathological diagnoses were infiltrating ductal carcinoma-neuroendocrine (NE) type. Immunohistochemistry showed estrogen, progesterone positivity and NE markers positivity in more than 50% of tumor cells for chromogranin, synaptophysin, neuron specific enolase. On further investigation by whole body computed tomography and magnetic resonance imaging revealed no extra mammary primary tumor. Hence the diagnosis of PNEC of breast was confirmed. Patient received chemo and hormonal therapy and doing well after 6 months of follow up.
A 58-year-old male patient presented with pain abdomen since 1 month and bilious vomiting since 1 week. After admission to our hospital, in view of his age and clinical presentation, upper gastrointestinal endoscopy was done and biopsy sent for histopathological examination. A diagnosis of Strongyloidiasis of duodenum was made. Herein, we report such an unusual case, where the diagnosis was first made by duodenal biopsy, rather than simple stool examination. Since the case clinically masqueraded as gastric malignancy, the importance of routine simple stool examination and role of pathologist in identifying the parasite is hereby highlighted.
