Classic paroxysmal nocturnal haemoglobinuria presenting with intestinal malabsorption syndrome, acute abdomen and acute kidney injury.

A male patient in his 30s presented with complaints of acute abdominal pain, black stools and red-coloured urine. CT revealed thrombi in the splenic and left renal veins, leading to infarctions. An endoscopy displayed scalloping of the duodenal folds, indicative of intestinal malabsorption syndrome (IMS). Histopathological examination confirmed IMS. Due to the presence of intravascular haemolysis, haemoglobinuria and thrombotic complications, paroxysmal nocturnal haemoglobinuria (PNH) was suspected and subsequently confirmed by flow cytometry. Thus, a diagnosis of classic PNH with IMS and thrombotic complications was established. This unique case highlights the coexistence of PNH and IMS, resembling the complement hyperactivation, angiopathic thrombosis and protein-losing enteropathy disease, suggesting potential shared pathophysiology.

Small cell neuroendocrine carcinoma with adenocarcinoma and high grade squamous intraepithelial neoplasia of the cervix.

Neuroendocrine neoplasm (NEN) of the cervix is a malignant tumor and is classified into low and intermediate-grade neuroendocrine tumor (NET), and high-grade small cell neuroendocrine carcinoma (SCNEC), and large cells neuroendocrine carcinoma (LCNEC). SCNEC of the cervix is an Infrequent tumor with an incidence of less than 1% of all gynecological malignancies. It is characterized by small to medium-sized tumor cells with scant cytoplasm and neuroendocrine differentiation. Most cases of SCNEC of the cervix manifest in pure forms, and only cases show coexisting, non-neuroendocrine component of HPV-associated adenocarcinoma or squamous cell carcinoma. In this report, reviewing the literature, we present one such unique case of SCNEC of the cervix with adenocarcinoma and high-grade squamous intraepithelial neoplasia.
