Duodenal Leishmaniasis Mimicking Celiac Disease in HIV Patient: A Case Report and Literature Review.

It is known that there are several clinical forms that diseases can take when presented in patients living with HIV, especially those in the AIDS phase. Here, we present a case that demonstrates the peculiar capacity of diseases to assume the most varied forms, highlighting the limited research on neglected infectious parasitic diseases. This study aimed to underscore the ability of these diseases to mimic other pathologies, emphasizing the importance of infectious diseases as differential diagnoses in the most diverse clinical entities, as is the case of visceral leishmaniasis.

Non-Hodgkin's Lymphoma (NHL) in people living with Human Immunodeficiency Virus/Acquired Immunodeficiency SyndromeHIV/AIDS) still constitutes a reality of high morbidity and mortality, sometimes not respecting the patient's degree of immunosuppression as it can even occur in those with a high CD4+ T lymphocyte count. Burkitt's lymphoma, in this sense, has been shown to be one of the main subtypes of this condition in this group of patients. This case report concerns a 32-year-old man diagnosed with metastatic gastric Burkitt's lymphoma after one month of his admission to a tertiary hospital for neurological complaints.

Can COVID-19 impact the natural history of paracoccidioidomycosis? Insights from an atypical chronic form of the mycosis.

Paracoccidioidomycosis (PCM) is a systemic fungal infection caused by Paracoccidioides spp. It can occur as an acute/subacute form (A/SAF), a chronic form (CF) and rarely as a mixed form combining the features of the two aforementioned forms in an immunocompromised patient. Here, we report a 56-year-old male patient with CF-PCM who presented with atypical manifestations, including the development of an initial esophageal ulcer, followed by central nervous system (CNS) lesions and cervical and abdominal lymphatic involvement concomitant with severe SARS-CoV-2 infection.
