[Bilateral bronchopneumonia due to Rothia mucilaginosa]. / Bronconeumonia bilateral por Rothia mucilaginosa.

Rothia mucilaginosa (R. mucilaginosa), formerly named Stomatococcus mucilaginosus, is a facultatively anaerobic, encapsulated gram-positive coccus, which forms part of the normal oropharyngeal and is rarely considered to be a pathogen in immunocompetent patients, although it can produce, on rare occasions, serious infections like bacteremia, endocarditis and respiratory infections; such as pneumonia, pleural empyema or superinfection of bronchiectasis. We present the case of a 74-year-old male diagnosed with right basal pneumonia of torpid evolution with a poor initial response to different antibiotics, with clinical and radiological worsening and the appearance of bilateral bronchopneumonia with pseudonodular images. R. mucilaginosa in pure culture was isolated in three sputum cultures and in bronchial suction. The patient was finally treated with Linezolid with a good clinical response and normalisation of the thorax radiography, confirming the disappearance of R. mucilaginosa in subsequent sputum cultures. As there are few documented cases of pneumonia due to R. mucilaginosa, we believe that presenting this case will be of interest.

[Arterial hypertension during pregnancy: Always preeclampsia?] / Hipertensión arterial durante el embarazo: ¿siempre preeclampsia?

Cushing's syndrome is a rare condition during pregnancy, but it is associated with serious maternal and fetal complications. The most common etiology during pregnancy is the presence of an adrenocortical adenoma. Urinary free cortisol over 3 times the upper limit of normal usually indicates Cushing's syndrome during pregnancy. The treatment of choice is surgical, and the ideal time for surgery is before the third trimester.

[Microvascular pulmonary tumor embolism in a patient with urothelial tumor]. / Embolismo tumoral pulmonar microvascular en paciente con tumor urotelial.

Pulmonary tumor embolisms (PTE) are an infrequent cause of dyspnea in oncological patients. The majority are diagnosed in patients with advanced tumors, above all localized in the breast, lung or stomach. There are few published cases involving patients with urothelial tumors. We present the case of a 69 year-old male, without a previous diagnosis of cancer, who was admitted due to subacute dyspnea, with clinical suspicion of pulmonary thromboembolism (PT). The patient died on the fifth day of admission. The autopsy confirmed the existence of a tumor in the left renal pelvis with hepatic and lymphoganglionary metastasis and an extensive microvascular pulmonary embolism that affected a large part of the capillaries and medium-caliber blood vessels of both lungs. PTE were considered responsible for the progressive respiratory failure and as the final cause of death. The most frequent clinical presentation of PTE is dyspnea. They are often mistaken for PT and diagnosis is not easy. Their prognosis is very bad, with extremely high mortality and confirmation is usually post-mortem.
