Recurrence of non-sexually acquired acute genital ulceration following COVID-19 vaccination.

There is a rare subset of non-sexually acquired acute genital ulcers, previously called Lipschutz ulcers, that are often preceded by a constitutional prodrome and have been associated with multiple viral and bacterial infections. These ulcers are categorized by some as a variant of complex aphthosis, with one hypothesized etiology involving a non-specific systemic inflammatory response to acute infection or vaccination. Although painful, these lesions resolve over the course of several weeks and recurrence is rare but possible.

Pediatric Keloids and Review of the Efficacy of Current Treatment Modalities.

Background: Keloids and hypertrophic scars are the result of excessive fibroblast proliferation and collagen deposition in the wound healing process, leaving patients with irritating and cosmetically displeasing lesions. Despite there being numerous modalities for treatment, keloids are notoriously recalcitrant to therapy and recurrence rates are high.

Objective: Because many keloids begin to develop during childhood and adolescence, it is important to better understand which treatment options may be best suited toward the pediatric population specifically.
