RESUMO
Stevens-Johnson syndrome and toxic epidermal necrolysis are potentially life-threatening cutaneous diseases that are rarely seen in the pediatric population. We describe a case of a 7-year-old female who presented with fever, cough, mucosal erosions, and a widespread maculopapular eruption with flaccid bullae for 4 days. She had no sick contacts and no new medications, supplements, or vitamins. She then rapidly developed ulcerations in her oral mucosa and genital area, numerous scattered tense bullae throughout her body, and patchy areas of desquamation. Infectious disease workup revealed positivity only for Bordetella parapertussis, and she was subsequently diagnosed with idiopathic toxic epidermal necrolysis.
RESUMO
Atrichia with papular lesions (APL) is a rare form of alopecia characterized by the diffuse, complete, irreversible loss of hair shortly after birth and the presence of diffuse keratotic papules and milia-like cysts. Multiple hairless gene (HR) mutations on the zinc finger domain of chromosome 8p12 have been associated with this disorder. We present the case of a 5-year-old girl with classic clinical findings of APL, with a diagnosis confirmed via genetic testing.
RESUMO
BACKGROUND AND AIMS: Cosmetic rejuvenation of the perioral area can be challenging due to a mix of skin laxity and volumetric loss. Current techniques including fillers, neurotoxins, and non-ablative and ablative resurfacing have several drawbacks and can create a stiff, box-shaped, unnatural appearance. Aside from filler, these techniques do not address deeper volume deficiency. Temperature controlled fractionated radiofrequency (FRF) provides consistent formation of new collagen, elastin, and hyaluronic acid. This has been reported to provide long-lasting results for the treatment of skin laxity and volume loss of the face and neck with a single treatment, but it has not been previously reported for perioral rejuvenation. PATIENTS/METHODS: We present a series of seven patients who were treated with perioral FRF, and we assessed their results objectively using a published, validated scale for lower face laxity. RESULTS: All of the patients in this case series showed improvement on the Facial Laxity Rating (FLR) scale after FRF treatment. CONCLUSIONS: This case series represents the first reported use of temperature controlled FRF for perioral rejuvenation. FRF is a promising option for low-risk, natural perioral rejuvenation with long-lasting results and few risks.

Cutaneous squamous cell carcinoma of the ear represents a high-risk tumor location with an increased risk of metastasis and local tissue invasion. However, it is uncommon for these cancers to invade through nearby cartilage. Cartilage invasion is facilitated by matrix metalloproteases, specifically collagenase 3. We present the unusual case of a 76-year-old man with an auricular squamous cell carcinoma that exhibited full-thickness perforation of the scapha cartilage. Permanent sections through the eroded cartilage confirmed tumor invasion extending to the posterior ear skin.
