Primary Vaginal Adenocarcinoma of Intestinal-Type: A Case Report of a Rare Tumor With Review of Histology, Differential Diagnosis, and Literature.

Intestinal-type adenocarcinoma is a rare primary vaginal carcinoma. Vaginal adenocarcinomas are most frequently a metastatic lesion, and less commonly, have clear cell histology and occur in young women with diethylstilbestrol (DES) exposure in utero. Due to the limited diagnostic power of immunohistochemistry (IHC) in differentiating primary from metastatic adenocarcinoma of the vagina, clinical and radiological correlation is critical in this scenario.

Desert soil fungi isolated from Saudi Arabia: cultivable fungal community and biochemical production.

Desert soils harbor fungi that have survived under highly stressed conditions of high temperature and little available moisture. This study was designed to survey the communities of cultivable fungi in the desert soils of the Arabian Peninsula and to screen the fungi for the potentially valuable antioxidants (flavonoids, phenols, saponins, steroids, tannins, terpenoids, and alkaloids) and enzymes (cellulase, laccase, lipase, protease, amylase, and chitinase). Desert soil was sampled at 30 localities representing different areas of Saudi Arabia and studied for physico-chemical soil properties.

Delayed acute myocarditis with COVID-19 infection.

Myocardial injury occurs in 20% to 30% of hospitalized patients with COVID-19 infection, and cardiovascular complications contribute to approximately 40% of all COVID-19-related deaths. Most cases of myocarditis related to COVID-19 infection occur in the acute phase of infection and are self-limited. We describe a case of delayed-onset fulminant myocarditis that developed 5 weeks after mild COVID-19 infection leading to cardiogenic shock and the need for mechanical circulatory support.

Vaginal Endosalpingiosis: A Case Report and Literature Review.

Endosalpingiosis is a benign condition with unclear pathogenesis and clinical significance and is defined as the presence of ectopic fallopian tube-like epithelium. It can be found in multiple locations, most commonly in the pelvic peritoneum covering the ovaries, uterus, and fallopian tubes, and less commonly found in the lymph nodes, omentum, appendix, cervix, vulva, or vagina. It is difficult to distinguish from endometriosis by gross appearance or localization, and theories propose that tissues of the secondary Mullerian system may undergo a metaplastic transformation, for example, from endosalpingiosis to endometriosis, which contributes to the debated association of endosalpingiosis with chronic pelvic pain.
