The diagnosis is primarily clinical, no pathognomonic test exists, and biopsy is rarely required, especially in well-developed lesions. [3] The consensus approach indicates that three key elements are required to diagnose hidradenitis suppurativa: typical lesions, characteristic distribution, and recurrence. Arbitrarily, two recurrences over a period of 6 months have been used as a qualifier for a diagnosis. [3] All three criteria must be present for the definitive diagnosis. [1]
