BACKGROUND AND OBJECTIVE: The effects of fractional resurfacing on eyelid tightening and aperture are unknown. Our purpose was to retrospectively examine the potential for eyelid tightening and eye-aperture opening in patients treated with nonablative fractional resurfacing for facial photorejuvenation. STUDY DESIGN/MATERIALS AND METHODS: Fractional laser treatments using a 1,550-nm erbium-doped fiber laser system on the upper and lower eyelids were given at a pulse energy of 17 to 20 mJ at 125 micro-thermal zones (MTZ)/cm(2) to a final density of 500 to 750 MTZ/cm(2). Each patient had 3 to 7 treatments. Standard pre- and post-treatment photographs were taken at each visit. Physicians who graded 31 preselected patient photographs using a 4-point scale evaluated eyelid tightening. Increase in eyelid aperture was also evaluated. RESULTS: All patients had some degree of eyelid tightening; 19% achieved 1% to 25% tightening, 26% achieved 25% to 50%, 26% achieved 50% to 75%, and 29% achieved 75% to 100%. Increase in eyelid aperture was seen in 55.9% of patients. Postoperative wounding, hypopigmentation, hyperpigmentation, persistent erythema, and scarring were not observed. All patients experienced mild or no edema for a few days after treatment. CONCLUSION: Fractional resurfacing tightens and increases eyelid aperture without wounding, downtime, or long-term complications

This case report seeks to alert the reader to the possibility that the keratoacanthoma (KA) may develop in tattoo sites, specifically in red tattoo sites. We further wish to describe the senior author's treatment of such a lesion using Mohs micrographic surgery and a rotation flap to preserve the integrity of the original tattoo design in an area of minimal skin laxity. We briefly discuss the etiology of the KA and review potential tattoo reactions as presented in the literature

BACKGROUND: Primary mucinous carcinoma of the skin is a rare sweat gland neoplasm which occurs most commonly in the periorbital region. Although the tumor has a propensity for local recurrence and regional spread, distant metastases are rare. The standard treatment of primary mucinous carcinoma is wide local excision. Mohs micrographic surgery may also be utilized in cases where tissue conservation is of utmost concern. OBJECTIVE: We present a case of primary mucinous carcinoma arising in the scalp, which was treated with wide local excision. METHODS: A case report and literature review are presented. RESULTS: Histopathologic evaluation revealed a well-circumscribed neoplasm characterized by lobules and aggregates of epithelial cells embedded in abundant pools of mucin. In addition, small aggregates of neoplastic cells were found at a distance from the primary nodule, indicative of lymphatic invasion. CONCLUSION: Primary mucinous carcinoma has a high propensity for locoregional metastases and recurrence. To our knowledge, this is the first report demonstrating direct histopathologic evidence of lymphatic invasion which correlates with this tumor's biologic behavior

A 35-year-old woman presented with cosmetically disturbing facial plaques, which had been present since birth and were consistent with nevus sebaceus on histopathologic examination. Nevus sebaceus is a congenital, hairless plaque, which is found most commonly on the scalp and face and typically becomes thicker and more verrucous in appearance as the patient enters adulthood. There is an association with benign and malignant neoplasms. Typically, these lesions are either removed surgically or the patients are followed clinically. Other therapeutic modalities utilized for cosmesis include carbon dioxide laser and photodynamic therapy

Summary Background Large congenital melanocytic naevi (LCMN), which develop in utero and are present in approximately one in 20 000 newborns, are associated with markedly increased risks of cutaneous melanoma, leptomeningeal melanoma and neurocutaneous melanocytosis (NCM). Objectives This study examined clinical characteristics associated with melanoma and NCM among patients with LCMN, and estimated the risk of developing melanoma and NCM in these patients. Methods Two hundred and five LCMN patients enrolled in the New York University registry were studied. One hundred and seventy of these patients were followed prospectively. The remaining 35 patients had either melanoma at the time of entry into the registry (n = 6), or had insufficient follow-up information (n = 29). The outcome measures were the occurrence of melanoma and NCM. The associations between these outcomes and the clinical covariates (anatomical location of the LCMN, size of the LCMN, number of satellite lesions, family history of melanoma, patient sex and treatment) were assessed. Results Four of 170 (2.3%) prospectively followed patients developed melanomas, representing a standardized morbidity ratio of 324. Among the entire cohort (n = 205), there were associations between increasing numbers of satellite naevi and the occurrence of melanoma (P = 0.04), and the presence of NCM (P = 0.06). Compared with patients who did not develop these diseases, median LCMN diameters were larger among patients who developed melanoma (49 vs. 39 cm) and NCM (55 vs. 46 cm). Conclusions In LCMN patients, increasing numbers of satellite lesions and larger LCMN diameters are associated with melanoma and NCM

A 23-year-old man presented for cosmetic consultation for symmetrically distributed, red-to-purple, hyperkeratotic papules that had been present since early childhood. Histopathologic features included ectasia of upper dermal vessels with overlying hyperkeratosis. Serum alpha-galactosidase A level was diminished. Fabry disease is an x-linked recessive disorder in which deficiency of the lysosomal enzyme alpha-galactosidase A leads to progressive accumulation of globotriaosylceramide in vital organs. The complexity and rarity of this disease mandates a multidisciplinary approach that includes initiation of enzyme replacement therapy
