The authors present the case of a rare extraventricular, intraparenchymal choroid plexus carcinoma (CPC). This 6-year-old girl presented to the emergency department with a 1-week history of headaches, nausea, and vomiting. Imaging studies revealed an intraaxial cystic and solid mass located in the right frontal lobe with central nodular enhancement and minimally enhancing cyst walls. Gross-total resection was accomplished via craniotomy without complications. The initial pathological diagnosis was atypical teratoid/rhabdoid tumor (AT/RT); however, immunostaining for INI1 protein (using the BAF47/SNF5 antibody) showed retention of nuclear staining in the tumor cells, resulting in a change in the diagnosis to CPC. There was no evidence of recurrence at the last follow-up 2.5 years after treatment, which supports the diagnosis of CPC over AT/RT. This case emphasizes the importance of immunostaining for INI1 protein for distinguishing CPC from AT/RT in cases with atypical or indeterminate features.

The pandemic of novel coronavirus disease (COVID-19) caused by the Severe Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) creates an immense menace to public health worldwide. Currently, the World Health Organization (WHO) has recognized the novel coronavirus as the main cause of global pandemic. Patients infected with this virus generally show fever, nausea, and respiratory illness, while some patients also manifest gastrointestinal symptoms such as abdominal pain, vomiting, and diarrhea. Traces of SARS-CoV-2 RNA have been found in gastrointestinal cells. Further angiotensin converting enzyme 2 (ACE2) the known receptor for the virus is extensively expressed in these cells. This implies that gastrointestinal tract can be infected and can also present them as a replication site for SARS-CoV-2, but since this infection may lead to multiple organ failure, therefore identification of another receptor is a plausible choice. This review aims to provide comprehensive information about probable receptors such as sialic acid and CD147 which may facilitate the virus entry. Several potential targets are mentioned which can be used as a therapeutic approach for COVID-19 and associated GI disorders. The gut microbiomes are responsible for high levels of interferon-gamma which causes hyper-inflammation and exacerbates the severity of the disease. Briefly, this article highlights the gut microbiome's relation and provides potential diagnostic approaches like RDT and LC-MS for sensitive and specific identification of viral proteins. Altogether, this article reviews epidemiology, probable receptors and put forward the tentative ideas of the therapeutic targets and diagnostic methods for COVID-19 with gastrointestinal aspect of disease.

Wilms' tumor is the most common primary renal malignancy in children (80%) and the less common tumors include renal cell carcinoma, rhabdoid tumor, clear cell sarcoma, cellular congenital mesoblastic nephroma and medullary carcinoma, all of which originate from renal parenchyma. The tumors originating from renal pelvis are rare. The immunohistochemistry (IHC) showed INI1 deletion with the WT1 positive which has not been reported as we know. A 3-year-old boy was admitted to hospital for vomiting. An ultrasonography examination revealed a mass in the right kidney, medium echo, as well as hydronephrosis with collecting system separation of 3.5 cm. The computed tomography and the magnetic resonance (MR) radical showed that the tumor occupied the right renal pelvis and extended into the ureter. A radical nephroureterectomy was accomplished through a transabdominal approach. The pathologic diagnosis was malignant renal tumor with INI1 deficiency which was atypical in morphology and immunophenotype, but according to immunophenotype renal rhabdomyoid tumor could not be excluded. The patient was treated with carboplatin, etoposide and cyclophosphamide chemotherapy for 6 months. Follow-up studies of the patient showed no indication of recurrence or metastasis 22 months after nephrectomy. The novel findings may expand the spectrum of pediatric renal tumors to include the special malignancy.
