due to the significant association with VDDRII. Histological exam performed on the alopecia area demonstrates thinning and hypoplastic hair follicles, with no specific scarring or inflammatory characteristics.1 Frequent biochemical alterations contribute to the diagnosis: high calcitriol with normal calcidiol, hypocalcemia, increased alkaline phosphatase, and phosphaturia and hypophosphatemia.1...

Some scholars have reported an association between AGA and coronary artery disease (CAD), probably due to alterations in CAD risk factors. However, this association is not supported by other studies, thus rendering the subject open to discus...
