Hidradenitis suppurativa and acne conglobata associated with spondyloarthropathy.

Hidradenitis suppurativa and acne conglobata are well-described chronic dermatologic diseases. Although the exact incidence of these disorders is unknown, both are relatively uncommon conditions. The incidence of spondyloarthropathy is less than 1% in the general population. Therefore, a triad of hidradenitis suppurativa, acne conglobata and spondyloarthropathy is a rare syndrome described only in a few case reports in the literature. We report a case of hidradenitis suppurativa and acne conglobata associated with spondyloarthropathy.
