Infiltrated papules on the trunk and headaches: A case of actinic granuloma and a review of the literature.

Actinic granuloma is a rare granulomatous reaction that is more commonly seen in females and thought to occur as an autoimmune response to actinic damage of elastic tissue. We discuss a case of a patient with actinic granuloma presenting with concomitant temporal arteritis. Our case and review of the literature emphasize the association between actinic granuloma and temporal arteritis, a serious inflammatory condition that could lead to blindness if misdiagnosed.

Advances in the management of cutaneous squamous cell carcinoma.

Cutaneous squamous cell carcinoma is one of the most common non-melanoma skin cancers worldwide.

The objective of this study was to analyze the frequency of off-label acne treatment according to age and other demographic factors.
