Introduction: Severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) responsible for the COVID-19 pandemic has spread from Wuhan, China in December, 2019 to 216 countries and territories as of September 10, 2020 with 27.74 million cases and 899,911 confirmed deaths. The spectrum of disease is most commonly seen as a viral pneumonia with high grade fevers, shortness of breath, dry cough, and chest pain with radiologic evidence of bilateral, interstitial, ground glass opacities, and peripheral lung consolidation. Liver chemistries are frequently abnormal, with transaminases shown to be one-two times the upper limit of normal in most instances. The full spectrum of gastrointestinal involvement of the SARS-CoV-2 infection has yet to be fully seen. Patient concerns: We present a case of a young woman with SLE who developed severe abdominal pain, nausea and vomiting, rapidly progressing to acute hepatic failure and tested positive for SARS-CoV-2 infection. She had no respiratory symptoms. Diagnosis: A thorough work-up of acute liver failure including liver biopsy confirmed acute hepatitis with viral like changes. Common viral causes of liver failure were ruled out. The patient had no recent travel history. Interventions: The patient was started on hydroxychloroquine due to SLE, treated with N-Acetyl-Cysteine, and methylprednisolone. Outcomes: The patient improved with resolution of encephalopathy and normalization of her liver chemistries without any development of respiratory illness. Conclusion: This case details a unique presentation of likely SARS-CoV-2 infection. Until now, the literature has primarily described a respiratory illness and liver injury with mild transaminase elevations. Significant liver injury progressing to acute liver failure should be considered in those with SARS-CoV-2 infection.
Mixed adenoneuroendocrine carcinomas (MANECs) of the biliary tract are rare tumors, and to date only a few cases arising in the gallbladder have been reported. Their histogenesis is a matter of debate, since the biliary tract normally lacks neuroendocrine cells. However, the immunohistochemical identification of nonneoplastic neuroendocrine cells in both biliary adenocarcinomas and intestinal metaplasia has been documented. Here we report a case of a 55-year-old female patient presenting with right upper quadrant pain, cholelithiasis, and a gallbladder mass identified after cholecystectomy. The histopathologic examination showed a MANEC, composed of an intestinal-type adenocarcinoma and a large cell neuroendocrine carcinoma, arising in a background of enteric metaplasia with extensive high-grade dysplasia. Moreover, we report the presence of focal pancreatic intraepithelial neoplasia-like epithelial lesions, which has not been described for these tumors yet. The histopathologic features of this case provide further support for the theory that MANECs arise following a metaplasia-dysplasia-carcinoma pathway.
Metastasis to the breast from an extra-mammary malignancy has been documented in literature, however cervical cancer metastasis to the breast is very rare. Thirty-eight cases of metastatic deposit to the breast from cervical cancer have been reported in literature. Though most patients present with a breast lump, it is very difficult to clinically distinguish a primary breast malignancy from a metastatic deposit. Histopathology of the tissue, aided with immune-histochemical staining pattern provides a definitive diagnosis. Our patient, a 51-year old woman presented with breast lump and history of post-menopausal bleeding. Upon further workup, the patient was diagnosed with cervical cancer. The mammogram and ultrasound of the breast showed multiple lumps within the breast. Histopathology of the breast mass showed metastatic deposit in the breast from cervical cancer. The patient was treated with radiation therapy to the cervix along with concurrent chemotherapy for local control of pain. After completion of local treatment, she started systemic chemotherapy, however she developed health-care associated pneumonia and subdural hematoma leading to deterioration in her performance status. The patient opted for hospice care and died 2 months later. In this report, we will review the presentation of the 38 cases reported in literature and the imaging and histopathologic findings of metastatic deposits to the breast.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
