Pyoderma Gangrenosum of the Breast: A Diagnostic Challenge

Area of Science:

• Dermatology
• Oncology
• Surgical Pathology

Background:

• Pyoderma gangrenosum (PG) is a rare, noninfectious neutrophilic dermatosis.
• Breast PG is an infrequent manifestation, posing diagnostic challenges.
• Understanding clinical features is key for timely diagnosis and management.

Purpose of the Study:

• To analyze the clinical features of patients diagnosed with breast PG.
• To identify potential triggering factors and diagnostic challenges associated with breast PG.

Main Methods:

• Retrospective review of medical charts for patients diagnosed with breast PG.
• Inclusion of patients from Bellvitge University Hospital between 2000 and 2023.
• Data collection focused on clinical presentation, evolution, and associated factors.

Main Results:

• Ten female patients aged 30-63 years were diagnosed with breast PG.
• Painful, ulcerated lesions were present in all patients; nipple involvement occurred in 4 cases.
• Breast reconstruction after carcinoma removal was the most common trigger (6/7 postsurgical cases), leading to diagnostic delays of 3-7 months in 6 patients.

Conclusions:

• Postsurgical breast reconstruction is a significant trigger for PG.
• Increased awareness among breast disease specialists is vital to reduce diagnostic delays.
• Prompt recognition can improve patient outcomes and prevent complications like pathergy.
