Pneumocystis jirovecii Pneumonia Accompanied with Fat Embolism: A Case Report.: Sung Hak Lee, Ok Ran Shin, Eun Jung Lee, Kyo Young Lee; Korean J Pathol. 2009;43(4):355-357.; DOI: https://doi.org/10.4132/KoreanJPathol.2009.43.4.355

Abstract PDF: Pneumocystis jirovecii is an atypical fungus that causes severe pneumonia in immune compromised patients. While Pneumocystis jirovecii pneumonia (PCP) is more commonly diagnosed in individuals who have HIV infection, it can occur in individuals with other forms of immunosuppression. Fat embolism most commonly develops after orthopedic injuries, but it has also been reported after other forms of trauma such as severe burns, closed-chest cardiac massage, and liposuction. Overlap in the clinical presentation of these diseases has not yet been reported. We report here on a case of PCP with fat embolism in 52-year-old female patient who had no obvious risk factors for HIV infection. Even if risk factors for HIV or other forms of immunosuppression are not present, PCP can also be seen in patients who present with fat embolism, and the clinical presentation of both conditions can overlap.

Abstract PDF: Amniotic fluid embolism is caused by the infusion of amniotic fluid into the maternal circulation with embolization to the lungs during pregnancy, labor or just after delivery. Clinically, this condition combines acute cardiopulmonary failure with a hemorrhagic tendency. We have experienced 11 autopsy cases of amniotic fluid embolism for about 2 years. The most common presenting feature was the postpartum uterine bleeding, followed by shock during oxytocin-induced labor. Histologically, various amount of amniotic debris, among which the most common component was epithelial squames, was demonstrated within the pulmonary vasculatures. In 4 cases, many fibrin thrombi were noted, reflecting the coagulation defect. Masson's trichrome and Alcian blue stains were proven to be valuable to demonstrate the squames and mucin, respectively.
