Treatment Considerations for Pyoderma Gangrenosum After Reduction Mammoplasty in an Unsuspecting Patient Demographic.

Pyoderma gangrenosum (PG) is a rare, often idiopathic, noninfectious inflammatory neutrophilic dermatitis that causes painful ulcerative cutaneous papillomatous lesions. PG often mimics surgical infection, wound dehiscence, and postoperative cellulitis, leading to high rates of misdiagnosis and mistreatment. Here, a healthy 17-year-old adolescent girl with congenital breast asymmetry, macromastia, and a history of only mild intermittent autoimmune conditions developed an open wound along her inferior left breast incision 2 weeks after reduction mammoplasty.

Background: Staphylococcus aureus, a known contributor to non-healing wounds, releases vesicles (SAVs) that influence the delicate balance of host-pathogen interactions. Efferocytosis, a process by which macrophages clear apoptotic cells, plays a key role in successful wound healing. However, the precise impact of SAVs on wound repair and efferocytosis remains unknown.

Primary cutaneous amoebiasis is rare, and typically affects immunocompromised patients and presents with unique clinical and histopathologic changes. Untreated, the infection could progress to involve the central nervous system, which is almost universally fatal. We present a case of primary cutaneous acanthamoebiasis in a patient with chronic lymphocytic leukemia on acalabrutinib.

Article Synopsis
- Leishmania (Viannia) braziliensis causes various types of leishmaniasis, and the study investigates how different subpopulations (Thor03, Thor10, Thor22) affect disease progression in BALB/c mice.
- The research found that after three weeks of infection, Thor03 and Thor10 led to larger lesions and influenced immune response markers, showing lower IL-12 and TNF levels, while Thor10 had the highest IL-10 levels.
- The study concluded that these subpopulations might lead to mild footpad lesions but can persist in lymph nodes, highlighting differences in infection patterns and immune responses among the subpopulations.
