Pyoderma Gangrenosum Precipitated by Breast Engorgement Following Lactation Discontinuation: A Rare Case Report

Pyoderma gangrenosum (PG) is an inflammatory disease characterized by recurrent painful ulcers, eventually leading to cribriform scars. PG is mostly a diagnosis of exclusion with neutrophilic skin infiltration. We present a case of a 35-year-old female patient whose first presentation of PG occurred in the first trimester of pregnancy, which recurred after discontinuation of breastfeeding. The patient also had a history of taking prolonged IM and IV analgesics for her chronic migraines. The patient was initially treated with steroids and necessary wound care, during which symptoms remained controlled. However, a year later, the patient presented with an acute flare-up of the disease in her postpartum period, mainly involving her breasts bilaterally. Extensive wound debridement was performed due to the severity of her necrotic ulcers and failure to respond to conservative management, which was followed by partial thickness skin grafting.
