Diagnosis of PG relies on which approach?

Explanation:
Diagnosis relies on clinical assessment combined with excluding other potential causes. Pyoderma gangrenosum has no single test that confirms it, so doctors look at the pattern of the ulcers (typically painful, rapidly expanding with undermined borders) and associated conditions (like inflammatory bowel disease or certain blood disorders) while ruling out infections, vasculitis, malignancy, and other ulcerative diseases. A biopsy can help exclude other conditions, but it is not diagnostic for PG and, due to pathergy, can worsen lesions. Because of this, the diagnosis is made by exclusion and careful evaluation rather than a definitive test.
