Diagnosis of granuloma annulare is primarily clinical, based on its distinctive appearance. A skin biopsy is crucial when the diagnosis is uncertain, revealing necrobiotic degeneration of dermal collagen surrounded by an inflammatory reaction. Distinguishing GA from other annular conditions like tinea or psoriasis is essential, as these conditions require different management approaches. Advanced diagnostic techniques, including dermoscopy, may assist in identifying characteristic patterns associated with the disease.
