Pyoderma Gangrenosum Following Deep Inferior Epigastric Perforator (DIEP) Breast Reconstruction: A Case Report
Bibliographic record
Abstract
Pyoderma gangrenosum (PG) is a rare dermatologic condition manifesting as sterile, rapidly progressing painful skin ulcerations. It is commonly associated with autoimmune disorders such as inflammatory bowel disease. This case report illustrates a severe case of post-surgical pyoderma gangrenosum (PSPG) following bilateral deep inferior epigastric perforator flap breast reconstruction in a 56-year-old Caucasian woman. Factors delaying diagnosis included negative personal/family history of inflammatory disorders and a clinical presentation more suggestive of breast cellulitis. Refractory antibiotic therapy, subsequent ulceration at multiple breast and abdominal incisions, and pathergic response to tissue biopsy supported an eventual clinical diagnosis of PSPG, 12 days postoperatively, despite equivocal histopathologic findings. Initiation of intravenous immunoglobulin, prednisone therapy, local wound care, and avoidance of debridement led to a full resolution by 5 months postoperatively. This study raises awareness for PSPG and highlights the importance of early recognition and urgent dermatology consultation to expedite optimal treatment and minimize subsequent fat necrosis.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
