Introducing a Case of Pyoderma Gangrenosum in the Breast

Introduction: Pyoderma gangrenosum (PG) of the breast is a rare that present as a painful ulcer on the skin. It usually affects people in their 20s to 50s and occurs in both men and women. Typically, PG affects the legs in adults. In children, it may affect the legs, buttocks, head, and neck. Pyoderma gangrenosum is characterized by a papule, nodule, or pustule that progresses to an injured lesion with unknown boundaries. In this study, a case of Pyoderma gangrenosum is introduced after breast surgery. A 38-year-old woman with a 3 cm wound in the right breast area that has gradually grown has been examined for exudative bloody discharge for the past 2 weeks. Two weeks after breast surgery, a three-centimeter progressive wound has formed on the surface of the breast, which gradually grew larger. During treatment, several oral and injectable antibiotics were prescribed that have not been effective in healing the wound. A biopsy lesion was reported in which a non-specific skin lesion with hyperplasia and vesicle formation without malignancy was reported. The patient had no gastrointestinal symptoms. Infliximab was started and continued for the patient. Conclusion: In the differential diagnosis of resistant skin wounds, especially in the leg area, and in this case in the breast the diagnosis of pyoderma gangrenosome should always be considered. Even if the patient has no history of inflammatory bowel disease, pyoderma gangrenosum may occur before intestinal manifestations.
