Rosacea causing unilateral Morbihan syndrome.

Morbihan syndrome is a rare entity causing woody induration of the face. There are numerous case reports of bilateral Morbihan syndrome. We present a case of a 46-year-old man with right infra-orbital cheek swelling and symptoms of rosacea who had histology consistent with granulomatous rosacea following debulking surgery. His clinical presentation and investigation findings support a diagnosis of rosacea causing unilateral Morbihan syndrome.

Cutaneous Nodular Amyloidosis: A Disfiguring Aspect of the Face.

Primary localized cutaneous nodular amyloidosis is a rare plasma cell dyscrasia in which an amorphous material consisting of light chain amyloid is produced and deposited in the dermis, with varied clinical presentation. We describe the case with unusual and tumor lush clinical presentation in the face with no progression to systemic disease and no evidence of extracutaneous commitment.

A Prospective Study in the Treatment of Lentigines in Asian Skin Using 532 nm Picosecond Nd:YAG Laser.

BACKGROUND AND OBJECTIVE: To evaluate safety and efficacy of treatment with the picosecond Nd:YAG 532 nm for lentigines in Asian skin. STUDY DESIGN/MATERIALS AND METHODS: This was a prospective, open-label cohort study, using a novel picosecond 532-nm laser for the treatment of facial lentigines. Subjects received up to three laser treatments every 4-6 weeks and were assessed at 4 and 12 weeks after final treatment. Primary endpoint was degree of improvement in lentigines at 12 weeks after the final treatment, assessed by treating investigator based on Physicians Global Assessment. Secondary end-points included degree of improvement in lentigines at 12 weeks after final treatment, assessed by subject (Subject's Global Assessment), and change in mean relative Melanin index (MI) value at 3 months after final treatment as compared to baseline as assessed by mexameter measurement. RESULTS: A total of 20 patients (3 male, and 17 female) of Asian-descent with Fitzpatrick skin type III and IV, with lentigines on the face were included in this study. A total of 89 lesions were treated with the laser setting of 532-nm, 750 picoseconds, fluence of 0.2-0.5 J/cm 2 , and spot size of 4 mm. One hundred and thirty-seven treatment sessions were given in total. Eighteen patients (90%) achieved a moderate to significant improvement at 12-week follow-up based on a 5-grade physician global assessment scale. The improvement rate of relative MI (MI in the lesion minus normal skin) was 33.30 ± 18.71 and 37.63 ± 19.25% at 4- and 12-week follow-up. Post-inflammatory hyperpigmentation (PIH) occurred in 14 of 137 sessions (10.2%), and hypopigmentation occurred in one patient with five lesions (3.6%). CONCLUSION: This study demonstrates that using picosecond Nd:YAG laser 532 nm for removal of solar lentigines in darker skin type appears to be safe and effective. Lasers Surg.

Effectiveness of Combining High-Intensity Focused Radiofrequency and Non-Ablative Fractional Laser for Improving the Appearance of the Aging Face and Neck

Background: The safety and effectiveness of high-intensity precision radiofrequency (RF) for rejuvenating the aging neck and face, and of fractional laser therapy for treating photodamaged skin have each been previously demonstrated. Objective: To assess the effects of combining high-intensity precision RF and fractional laser therapy for treating the aging face and neck. Methods and Materials: Subjects (N=19) with Fitzpatrick skin types I to VI and mild-to-moderate solar elastosis and sun or age-related pigmentation on the face and/or neck were sequentially treated with high-intensity precision RF and fractionated laser devices during the same session. Three sessions were completed 30 days apart. Assessments were made 90 days after the last treatment. Results: Both Clinician and Subject Global Assessment of Improvement scores indicated clinical improvement (n=16, 84%) or no change (n=3, 16%) in skin quality. Clinical improvement was also observed in 16 subjects (68%) in masked assessment. Most subjects (90%) noted improved skin quality and 74% expressed at least some satisfaction with their treatment results. The most common adverse events were erythema (n=57, 45%) and edema (n=45, 35%). Conclusion: The results of this study establish the safety and effectiveness of combined treatment with a 1927 nm thulium laser and a high-intensity precision RF device.

The rapid effect of pulsed dye laser on demodex density of facial skin.

BACKGROUND: Recently, treatment with acaricides, which is aimed at reducing excessive proliferation of demodex mites, has gained popularity due to its providing a significant improvement in the symptoms of diseases, such as rosacea, seborrhoeic dermatitis, and perioral dermatitis. The effect of IPL on demodex mites was reported in skin biopsy specimens in three patients; however, to the best of our knowledge, no study exists to date, which evaluates the effect of pulsed dye laser (PDL) on demodex density (Dd) in larger patient group. We aim here in to observe the Dd before and after PDL therapy with two different skin biopsy techniques. MATERIAL AND METHODS: Thirty-one patients diagnosed with rosacea were included in the study who received PDL treatment. Dds which were measured by using both the SSSB (standardized skin surface biopsy) and CTM (cellophane tape method) techniques before and after 3 weeks of PDL therapy were evaluated. RESULTS AND DISCUSSION: The Dd of patients before PDL treatment was 13.0 (interquartile range (IQR): 5.0-28.0) and after 3 weeks of PDL treatment it was 6.0 (IQR: 3.0-12.0) with SSSB. After PDL treatment, the Dd was significantly lower than pretreatment the Dd (p = 0.002). The present study shows that PDL significantly reduced Dd in facial skin with one session.

Fractional 532-nm KTP diode laser and 595-nm pulsed dye laser in treatment of facial telangiectatic erythema.

BACKGROUND: A 595-nm pulsed dye laser (PDL) and the fractional 532-nm potassium titanyl phosphate (KTP) laser have also been demonstrated to be effective for facial telangiectasias. OBJECTIVE: To compare the clinical therapeutic effects of a fractional 532-nm KTP laser with those of a 595-nm pulsed dye laser (PDL) for treating facial erythematous skin lesions. METHODS: Twenty healthy adults with facial erythematous skin lesions were treated using a fractional 532-nm KTP laser on one side of the face and a 595-nm PDL on the other cheek. Three treatments were administered at 4-week intervals. The degree of improvement in facial telangiectasias was evaluated by colorimeter analysis, a physician's assessment using clinical photographs, and the subject's self-assessment. RESULTS: In the physician's assessment with clinical photography, a significant improvement was observed from baseline to posttreatment in both groups. As measured by a colorimeter, the a* value decreased from 16.23 (±2.81) to 12.22 (±2.75) in the 595-nm PDL group and from 16.02 (±2.93) to 12.77 (±2.77) in the fractional 532-nm KTP laser group. The a* value showed a significant reduction in both groups (P < .0001). There was no significant difference in efficacy between the two groups. In the subjective self-assessment, scores improved by 1.68 (±0.95) in the fractional 532-nm KTP laser group and by 1.78 (±0.92) in the 595-nm PDL group. CONCLUSION: A fractional 532-nm KTP laser is a valid option for the treatment of facial erythematous skin lesions with telangiectasia.

Comparison of novel dual mode vs conventional single pass of a 1450-nm diode laser in the treatment of acne vulgaris for Korean patients: A 20-week prospective, randomized, split-face study.

BACKGROUND: Although a 1450-nm diode laser has been shown to be effective for acne, the conventional high-energy stamp-only regimen is often associated with pain and hyperpigmentation, especially for dark-skinned individuals. AIMS: To evaluate whether the novel dual regimen has clinical advantages for acne treatments compared with conventional regimen in Asian patients. PATIENTS AND METHODS: Twenty-four Korean patients with facial acne were treated with a 1450-nm diode laser through a 20-week, randomized, split-face study. The patients were treated with three consecutive sessions at 4-week intervals. One half of the face received a dual regimen consisting of low-fluence stamping mode (5-6 J/cm2 ) for inflammatory acne lesions only, followed by 4-5 passes of moving mode for the full face. The other side received a single-pass treatment of conventional high-fluence stamp mode (14-15 J/cm2 ). Evaluations for acne, sebum secretion measurements, and safety profiles were performed. RESULTS: At the final 12-week follow-up evaluations, the dual-mode side demonstrated better improvements in both inflammatory and noninflammatory lesion counts, acne severity assessments, and reduction in sebum secretion compared with stamp-only side. Subjective satisfaction for the improvement for acne, seborrhea, and texture correlated well with objective assessments. In addition, degrees of pain and treatment-related side effects were remarkably decreased in the novel dual mode. CONCLUSION: This novel dual regimen of the 1450-nm laser demonstrated improved efficacies for acne and seborrhea with satisfactory safety profiles. Therefore, this regimen would be a viable option for acne treatments either as monotherapy or as combination therapy.

Plasma Exeresis Treatment for Epidermoid Cysts: A Minimal Scarring Technique.

BACKGROUND: Epidermoid cysts are cutaneous benign tumors commonly seen in young or middle-aged adults. Plasma exeresis is an innovative technique for several skin conditions: it causes ionization of the atmospheric gas between the proximal tip of the device and the tissue to be treated, creating sublimation of the tissue. OBJECTIVE: To remove the cyst with a novel technique that allows a good cosmetic result. MATERIALS AND METHODS: Patients with clinical diagnosis of at least one epidermal cyst, aged between 18 and 70 years were enrolled. A standardized procedure was used. After administration of topical and sometimes local anesthesia (for cysts bigger than 1 cm), a tiny hole was created with plasma exeresis. The content of the cyst was then extruded and Micro Hartman Alligator Ear Forceps pulled out the loosened capsule. RESULTS: Twenty patients aged between 18 and 68 years were enrolled: 11 males (55%) and 9 females (45%). Twenty-eight cysts were successfully removed. The diameter ranged from 3 to 24 mm. No side effects were observed. The scar measured not more than 3 mm. CONCLUSION: This study suggests that plasma exeresis could represent a good and safe option to remove noninfected cysts on cosmetic areas, although further study is required.

[Trichodysplasia spinulosa. Report of one case]. / Tricodisplasia espinulosa asociada a síndrome mielodisplásico e inmunosupresión.

Trichodysplasia spinulosa is a rare disease that occurs in the setting of immunosuppression, associated with tolerogenic therapy used in allograft recipients or patients with hematologic malignancies. Clinically, it is characterized by a centrofacial cutaneous eruption of erythematous papules with a central keratinous spicule, often associated with variable degrees of alopecia. Histologic findings are characteristic, and electron microscopy reveals the presence of trichodysplasia spinulosa associated polyomavirus. We report a 47-year-old woman with idiopathic autoimmune pancytopenia refractory to diverse immunosuppressant regimens, with clinical and pathologic findings compatible with the disease, in whom complementary studies were required to exclude other differential diagnoses.

Keloid Skin Flap Retention and Resurfacing in Facial Keloid Treatment.

OBJECTIVE: Facial keloids commonly occur in young patients. Multiple keloid masses often converge into a large lesion on the face, representing a significant obstacle to keloid mass excision and reconstruction. We describe a new surgical method that excises the keloid mass and resurfaces the wound by saving the keloid skin as a skin flap during facial keloid treatment. METHODS: Forty-five patients with facial keloids were treated in our department between January 2013 and January 2016. Multiple incisions were made along the facial esthetic line on the keloid mass. The keloid skin was dissected and elevated as a skin flap with one or two pedicles. The scar tissue in the keloid was then removed through the incision. The wound was covered with the preserved keloid skin flap and closed without tension. Radiotherapy and hyperbaric oxygen were applied after surgery. Patients underwent follow-up examinations 6 and 12 months after surgery. RESULTS: Of the 45 total patients, 32 patients were cured and seven patients were partially cured. The efficacy rate was 88.9%, and 38 patients (84.4%) were satisfied with the esthetic result. CONCLUSION: We describe an efficacious and esthetically satisfactory surgical method for managing facial keloids by preserving the keloid skin as a skin flap.
