ABSTRACT
This case report presents a difficult-to-diagnose case of American tegumentary leishmaniasis (ATL) caused by Leishmania (Viannia) guyanensis in a 24-year-old Hispanic male with a travel history to the Panama jungle, an endemic region for tropical infectious diseases. The patient initially presented with persistent skin lesions that progressed to abscesses with ulceration. Despite negative initial diagnostic tests, including microbiological investigations and histopathological examination, a comprehensive diagnostic workup and subsequent polymerase chain reaction (PCR) confirmed the presence of Leishmania parasites. This case underscores the need to consider tropical infectious diseases despite initial negative tests. Accurate species identification is vital for proper drug treatment, with miltefosine as an emerging option. Early, precise diagnosis and tailored management are essential for successful treatment. This report emphasizes the significance of conducting a comprehensive diagnostic workup, including PCR, in individuals with a history of travel to endemic regions, to accurately diagnose and effectively manage complex infectious diseases.
ABSTRACT
Emphysematous urinary tract infections (EUTIs) are rare, severe, and suppurative infections affecting various parts of the urinary tract. We report a case of a 75-year-old male presenting with hematuria and generalized weakness with uncontrolled diabetes mellitus (DM) and hypertension. He tested positive for COVID-19 on the second day of hospital admission. A non-contrast-enhanced CT of the abdomen and pelvis revealed gas within the left renal parenchyma, walls of the left ureter, and urinary bladder, establishing the diagnosis of EUTIs. The patient was treated using intravenous antibiotics without any surgical intervention, and four weeks later was stable and transported to long-term acute care (LTAC) facility. DM is the most common risk factor for the development of EUTIs and Escherichia coli is the most common causative pathogen.
