Making Sense of Late Tissue Nodules Associated With Hyaluronic Acid Injections.

Background: The pathogenesis of delayed-onset tissue nodules (DTNs) due to hyaluronic acid (HA) injections is uncertain.

Methods: A multidisciplinary and multicountry DTN consensus panel was established, with 20 questions posed and consensus sought.

Why we should be avoiding periorificial mimetic muscles when injecting tissue fillers.

Background: Tissue fillers are generally safe and well tolerated by patients. However, complications do occur and may be very severe, such as intravascular injection (with occasional residual tissue loss, visual and neurological sequelae) and late nodularity and swelling. Methods to lessen the likelihood of complications have been the subject of much recent literature.

Warts are not merely blemishes on the skin: A study on the morbidity associated with having viral cutaneous warts.

Eighty-five people aged 2-76 years with 250 common and plantar warts were followed prospectively for 9 months. The majority (57; 67%) had one to two warts. Of the 54 subjects who had a past history of warts, 41 (75.

Subacute cutaneous lupus erythematosus presenting in a child.

A 5-year-old girl presented in summer with an erythematous, scaly annular eruption in a malar distribution. She had no symptoms or signs of systemic lupus erythematosus. A diagnosis of subacute cutaneous lupus erythematosus was made on the basis of the clinical and histological features, positive anti-Ro antibody and a mildly elevated erythrocyte sedimentation rate.
