Hori nevus, also known as acquired bilateral nevus of Ota-like macules, is a form of dermal melanocytosis found most commonly in women of East Asian heritage. It presents as discrete brown macules on the bilateral cheeks which later coalesce into confluent grey-brown macules and small patches. Herein, we report a classic case of Hori nevus and discuss the histologic findings and differential diagnosis. We also review the proposed pathophysiology, genetic considerations, and treatment options.

Non-melanoma skin cancer (NMSC) is the commonest malignancy worldwide (>80% located in the head and neck area). The aim of this study was to assess risk factors predisposing to local recurrence of NMSC of the middle third of the face (MTF). This was a single-centre retrospective analysis of patients with NMSC of the MTF treated during 1995-2010. Data on epidemiological and tumour characteristics were collected. Survival analysis was performed and log-rank tests were used to compare differences in survival for each variable. A total of 531 patients with basal cell carcinoma (BCC) of the MTF were identified. Most tumours were nodular type (28.4%), located on the nose (34.3%), and confined to the dermis (75.5%). Negative margins were achieved in 91% of cases. Median follow-up time was 35 months and 15.2% of patients developed local recurrence. Incomplete excision was the only variable predisposing to local recurrence. The cohort also included 114 patients with squamous cell carcinoma (SCC). Most tumours were well differentiated (43.9%), located at the zygomatic area (49.1%), excised with negative margins (93%), and confined to the dermis (67.8%). At a median follow-up time of 42 months, local recurrence occurred in 15.7% of patients. Tumour size, depth of invasion, and prior history of head and neck SCC were risk factors for local recurrence. The variables predictive of recurrence of BCC were incomplete excision and for SCC tumour size, depth of invasion, and a prior history of head and neck SCC.

Although Mohs micrographic surgery (MMS) is the gold standard for treatment of nonmelanoma skin cancers (NMSCs), laser management has been an emerging treatment option that continues to be studied. Nonablative laser therapy is a noninvasive alternative. This study used a combined pulsed dye laser (PDL) and fractional laser approach to treat basal cell carcinomas (BCCs) in conjunction with noninvasive imaging such as reflectance confocal microscopy (RCM) and optical coherence tomography (OCT) to enhance efficacy rates.

Brachytherapy of skin tumours uses custom applicators that are manufactured manually. The integration of 3D printing customization of applicators during hidh dose rate brachytherapy planning could allow a better skin conformation and a better reproducibility of the positioning and treatment. We present the technical implementation of this method for our first two patients. A provisional planning scanner was carried out to create a digital applicator. The creation of the digital applicator used successively several software programs. The first, commercial, was RhinocerosR 3D used via Grasshopper, an integrated open source plug-in. The 3D applicator was then exported to the commercial software Simplify3DR. A g-code format file was generated for the printer. A second scanner was made with a 3D applicator in place to plan the final treatment. The treatment was planned by reverse optimization. The applicator could be designed within 15 days. For patient A, it was noted that 95 % of the clinical target volume received at least 35.4Gy (63Gy EQD2). For patient B, 95 % of the clinical target volume received at least 36Gy (64.8Gy EQD2). The forecast and actual planimetry met the coverage criteria of D95. Contact brachytherapy with 3D bioimpression is feasible, after software training, for complex treatment lesions. This technique could be extended to other indications.

Radiotherapy is essential for achieving and maintaining local control in head and neck rhabdomyosarcoma patients. However, radiotherapy may cause outgrowth disturbances of facial bone and soft tissue, resulting in facial asymmetry.Several studies have shown that the management of irradiated bones still remains challenging. The possibility of obtaining functional and aesthetic results when managing facial deformities due to radiation therapy with distraction osteogenesis combined with free flaps reconstruction is not common and not well documented in recent literature.In this report, we present the long-term results of distraction osteogenesis and soft tissue reconstruction via microvascular free flap to correct the facial hypoplasia of a young patient who underwent radiation therapy for rhabdomyosarcoma.This is the first presentation of 26 years long-term results in a patient who also underwent free flaps reconstruction as ancillary surgery for esthetic good results.

BACKGROUND: To assess the effectiveness and outcomes of adjuvant radiotherapy regimens for nonmelanoma skin cancers (NMSC) of the head and neck, particularly for elderly patients. METHODS: A retrospective review of patients with head and neck NMSC was conducted. Radiotherapy dose per fraction regimens included ≤200, 240-250, 300-400, and 500-600 cGy. Demographics, tumor characteristics, local control (LC), regional control (RC), and survival outcomes were analyzed. RESULTS: Of the 90 patients with 140 disease sites, 76.6% were squamous cell carcinoma, 15.5% were basal cell carcinoma, and 7.7% were other histologies. The mean age at diagnosis was 72.1 years old. The most common location was preauricular (20.0%), followed by temple, scalp, cheek, and forehead. The overall LC and RC rates were 88.8% and 88.8%, respectively by patients, and 92.8% and 86.4%, respectively by treatment sites. Age, primary tumor location, T classification, N classification, overall stage, perineural invasion, comorbid disease, skull base invasion, and radiotherapy subgroup were significantly associated with disease-free and overall survival (P < 0.05). LC and RC were not significantly different among the radiotherapy dose subgroups. The mean survival was longer in patients treated with 240-250 cGy/fraction (50.3 months). There was no significant difference in radiotherapy toxicity between the subgroups. CONCLUSION: Short-term radiotherapy regimens for patients with locally or regionally advanced head and neck NMSC appear feasible and effective, particularly in elderly patients or those that cannot tolerate the length of standard regimens.

OBJECTIVE: Nevus of Ota represents congenital dermal melanocytosis in a trigeminal distribution, most commonly occurring in Asian individuals and other individuals with skin of color. Evidence suggests early treatment is beneficial. Multiple reports have shown efficacy and safety of Q-switched laser treatment in adults. There is little data on children and in non-Asian skin types. This series was done to demonstrate safe and effective use of Q-switched laser therapy in children of multiple skin types. STUDY DESIGN: Retrospective case series. METHODS: This was a chart review of patients under 18 years old who presented to our practice from 2002 to 2015 with a clinical diagnosis of nevus of Ota who were treated with Q-switched lasers (694 and 1,064 nm). Patients were treated without the use of general anesthesia or sedation, and corneal shields were used in appropriate cases. Percentage of improvement as well as side effects were rated by five physicians independently. Improvement, when present, was rated in quartiles (1-25%, 26-50%, 51-75%, and 76-100% improvement). RESULTS: Twenty-four children were included. The average age at the start of treatment was 3.9 years old (range of 3 months to 12.4 years), and patients had Fitzpatrick skin types IV through VI. The mean number of treatments was 9.3. Assessment revealed excellent response (76-100% improvement) in 70% of patients and good to excellent response (51-100% improvement) in 86%. Two patients (8%) had post-inflammatory hyperpigmentation, one of whom also had focal hypopigmentation. CONCLUSION: Treatment of nevus of Ota with Q-switched lasers in children with skin of color, without general anesthesia or sedation, is safe and effective. Early intervention should be encouraged for better efficacy and to prevent psychosocial distress in later childhood and adulthood. Lasers Surg. Med. 50:56-60, 2018. © 2017 Wiley Periodicals, Inc.

A 25-year-old Chinese woman presented with recurrent painless swelling over the left medial canthus region for 3 months and intranasal mass for an indeterminate duration. Initial incision biopsy of the mass was reported as nodular fasciitis but the lesion recurred 3 weeks later. Intraoperative findings during repeat biopsy showed a mass extending from the deep dermal tissue into the anterior orbit and polyp-like nasal mass. Histopathology findings were that of dermatofibrosarcoma protuberans (DFSP). The mass recurred 4 months later without orbital or intranasal recurrence. Wide excision biopsy under frozen section guidance was attempted however; clear surgical margins could not be achieved despite extensive resection. She was subsequently referred for adjuvant radiotherapy. We report an exceptionally rare case of local recurrence of DFSP in an unusual anatomic location. This case was surgically challenging in achieving negative margins, and thus neoadjuvant therapy may improve overall outcome to prevent local relapse.

The treatment of midfacial tumours with radiotherapy, chemotherapy and radio-iodine can cause nasolacrimal duct fibrosis resulting in epiphora. Nasolacrimal patency can be maintained by stenting. We report our experience of prophylatic Nunchaku stent insertion in 5 patients prior to midfacial radiotherapy. Four out of 5 patients (80%) had patent nasolacrimal ducts without any symptoms of epiphora following removal of the stents. One patient was initially asymptomatic with patent nasolacrimal duct, but subsequently developed epiphora. Nunchaku stents may provide a simple and effective way of preventing epiphora, obviate the need for nasal retrieval that is required for other nasolacrimal stents, and reduce the risk of requiring further lacrimal surgery.

Dermal filler injection has been one of the most evolving areas of interest in the field of esthetic plastic surgery. This procedure is sometimes preferred to surgery due to shorter procedure and patient recovery times, and because it is suitable for a wide range of applications. Dermal filler injection is considered to be relatively safe, but various late complications such as infection and foreign body granuloma sometimes occur. Postprocedure development of lymphoma also occurs, but is extremely rare. The authors diagnosed extranodal marginal zone B-cell lymphoma of the mucosa associated lymphoid tissue that developed after a filler injection procedure was performed on a patient's face. This 72-year-old female first presented with a palpable mass on her left cheek that developed after a probable silicone injection. An magnetic resonance imaging (MRI) scan and excisional biopsy confirmed the presence of the lymphoma. Complete remission occurred after radiotherapy. This rare case of lymphoma in a patient with a history of foreign body injection indicated that practitioners must be aware that long-standing chronic inflammation resulting from dermal filler injections can trigger lymphoma development.

Merkel cell carcinoma is an aggressive, malignant, neuroendocrine tumor of the skin. The aim of the study is to present the clinical pictures, methods and results of treatment of MCC in the Clinic of Maxillofacial Surgery in Rzeszow in years 2003-2010. Changes were located on the skin of the face of four patients. All patients were treated surgically, the primary change was removed. Recurrence after surgical treatment was observed in all patients. The observations confirmed the data from the literature about the incidence of MCC over 75 years of age, aggressiveness and difficulties in treatment of this disease.
