Dermatology Partners Discloses Data Breach Affecting Maryland Patients Dermatology Partners, a multi-state dermatology group with over 30 offices across Pennsylvania, Delaware, and Maryland, recently reported a data breach at its Catonsville, Maryland, location. Between February 27 and March 10, 2026, an unauthorized individual accessed the office’s data system. While the company’s investigation found no evidence that patient data was copied or removed, it could not confirm which specific records were viewed during the breach. As a precaution, Dermatology Partners notified all patients seen at the Catonsville office. Potentially exposed information includes names, dates of birth, addresses, contact details, medical record numbers, treatment histories, diagnosis data, and health insurance details. The breach notice was posted on the company’s website on June 23, 2026, though the total number of affected patients remains undisclosed.
