More difficult still: Treating severe rapidly progressive glomerulonephritis in the context of COVID-19 pneumonia.

We present the case of a male patient with severe SARS-CoV-2 pneumonia, with simultaneous onset of p-ANCA positive rapidly progressive glomerulonephritis. We discuss the different therapeutic possibilities, emphasising the appropriateness of their administration according to the time in the course of the infection.

Primary Pure Pancreatic -Type Acinar Cell Carcinoma of the Stomach: A Rare Entity with a Difficult Diagnosis and Review of the Literature.

Acinar cell carcinoma is an uncommon tumour, representing only 1% to 2% of all exocrine pancreatic tumours. Pancreatic-type acinar cell carcinoma can occur in other organs, including the stomach, but it is extraordinarily rare. We report a case of a 51-year-old woman with a pancreatic-type pure acinar carcinoma of the stomach coexisting with a large cell B lymphoma synchronously, and a literature review of gastric carcinomas with pancreatic cell differentiation. At present there is a preoperative underdiagnosis of these tumours that could be minimized by including this entity in the differential diagnosis of gastric cancer and by performing immunohistochemical analysis with neuroendocrine markers and exocrine pancreatic enzymes.

Más difícil todavía: tratar una glomerulonefritis rápidamente progresiva grave en el seno de una neumonía por COVID-19 / More difficult still: Treating severe rapidly progressive glomerulonephritis in the context of COVID-19 pneumonia

Presentamos el caso de un varón afecto por neumonía SARS-CoV-2 grave, que a la vez comienza con una glomerulonefritis rápidamente progresiva p-ANCA positiva. Se comentan las distintas posibilidades terapéuticas haciendo hincapié en la idoneidad de su administración según el momento evolutivo de la infección. (AU)

Primary thyroid tuberculosis: a case report.

Involvement of the thyroid gland by tuberculosis is very rare and is usually secondary to disseminated infection. Very few cases of primary thyroid tuberculosis have been described even in countries with a high incidence of this disease. We present the case of a Spanish patient operated for a suspicious thyroid nodule that was finally diagnosed as primary thyroid tuberculosis.

La afectación de la glándula tiroidea por tuberculosis es muy rara y generalmente es secundaria a una enfermedad ­diseminada. Se han descrito muy pocos casos de tuberculosis tiroidea primaria incluso en paises con alta incidencia de esta enfermedad. Presentamos el caso de una paciente española operada por un nódulo tiroideo sospechoso que fue finalmente diagnosticado como tuberculosis tiroidea primaria.
