Dermatofibrosarcoma Protuberans in "Slow Mohs-tion": Multidisciplinary Approach of A Pediatric Dermatofibrosarcoma Protuberans of the Scalp with Slow Mohs Micrographic Surgery and A Double Rotational-Advancement Scalp Flap.

Dermatofibrosarcoma protuberans (DFSP) is an uncommon soft-tissue sarcoma with primary incidence of 4.1 per million person-years and accounts for 0.1% of all malignancies. In patients under the age of 19, DFSP comprises 6% of cases with an annual incidence of 1 in 1,000,000. It is a slow-growing malignancy with low metastatic potential. However, DFSP is notable for its high rates of local recurrence due to local invasion with its classic "finger-like" projections into normal tissue. We discuss a case of dermatofibrosarcoma protuberans on the scalp of a 14-year-old male with delayed diagnosis, which required extensive resection through slow Mohs Micrographic Surgery (sMMS). This resection created a sizeable scalp defect of nearly 100 cm2, which mandated creative reconstruction using a novel double rotational-advancement scalp flap to close the defect while maintaining the patient's hairline for optimal cosmesis.

Postoperative Pain After Mohs Micrographic Surgery is Well Tolerated Regardless of Psychological and Pain-Related Comorbidities.

BACKGROUND: Preoperative patient screening has been evaluated in many surgical specialties as a way to improve the overall patient experience. Current data are limited regarding patient screening for dermatologic procedures. The goal of preoperative screening is to identify patients at risk for poor outcomes and tailor the treatment plan to ensure a greater overall patient experience. OBJECTIVE: To investigate the association between psychological comorbidities and acute postoperative pain in patients treated with Mohs micrographic surgery (MMS). MATERIALS AND METHODS: Subjects were recruited from a single center, single provider, uniformed service MMS practice, and asked to complete preoperative and postoperative questionnaires for scheduled MMS. Outcome variables included anticipated pain, actual pain after MMS, duration of pain, and medications used for pain. RESULTS: Mohs micrographic surgery was well tolerated. There were no significant differences in anticipated or reported pain, or in medication use between cohorts. Significant differences in pain were noted with closure technique with complex surgical repairs generating the greatest pain across groups. CONCLUSION: Mohs micrographic surgery is well tolerated by patients, both with and without psychological comorbidities. Our results show no statistically significant differences, suggesting a limited role for preoperative screening as a tool to guide pain management after MMS.

Two Suturing Techniques for the Prevention and Treatment of Nasal Valve Collapse After Mohs Micrographic Surgery.

BACKGROUND: Tumor extirpation of nonmelanoma skin cancer (NMSC) adjacent to the alar groove, using Mohs micrographic surgery (MMS), may risk causing internal nasal valve (INV) collapse, resulting in reduced airflow during inspiration. There are many surgical options described in the literature to repair INV collapse as a postoperative corrective procedure, but few exist as an intra-operative preventative procedure. OBJECTIVE: The authors present 2 distinct methods to prevent and treat INV collapse during the repair of a perialar surgical defect caused by MMS. METHODS: A 3-point stitch method or a modified suspension suture technique was used to prevent INV collapse during the repair of MMS defects overlying the alar groove, for nonmelanoma skin cancers. The 3-point stitch was used with a complex repair. The modified suspension suture was used with flap reconstruction. RESULTS: The 3-point stitch and the modified suspension suture are simple, single-stage surgical solutions for perialar defects with collapse of the INV caused by loss of subcutaneous tissue during MMS. Once executed, patients experienced immediate subjective airflow improvement which was also supported by clinical examination. Patients were followed at 1 week and at 3 months postoperatively. Thirty-four of 35 patients reported good functional and cosmetic results and were satisfied with the final outcome. CONCLUSION: The 3-point stitch and the modified suspension suture techniques are easy and simple methods that can be incorporated into reconstruction after MMS for defects of variable depth covering any multisubunit perialar region to prevent or correct INV collapse.

Angioimmunoblastic t-cell lymphoma presenting as purpura fulminans.

Purpura fulminans is a nonspecific hematologic emergency with high initial mortality, representing a thrombotic occlusion of blood vessels leading to skin necrosis and disseminated intravascular coagulation, and often reported in the setting of sepsis. We report a case of nonfatal purpura fulminans in the context of angioimmunoblastic T-cell lymphoma (AITL).

Case report: challenges in the diagnosis of adenopathy and extensive skin patch overlying a plasmacytoma syndrome.

Overproduction of a vascular endothelial growth factor secreted by neoplastic cells in some plasma cell neoplasms is postulated to be responsible for the syndrome of polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, and skin changes and the rarer syndrome of adenopathy and extensive skin patch overlying a plasmacytoma. The authors present a case of a 57-year-old man who presented with an erythematous left flank skin patch and subsequent discovery of an underlying 10th rib plasmacytoma with lambda light chain restriction. The tumor was strongly positive for CD31, a marker known to be involved in angiogenesis and cell adhesion. Immunohistochemical studies were initially confounding and later shown to be due to the effects of decalcification procedures. The authors discuss the natural history of this unusual entity and the diagnostic challenges in evaluating this lesion. The authors finally postulate whether strong CD31 expression could be related to paraneoplastic phenomena associated with some plasma cell lesions.

Adenopathy and extensive skin patch overlying a plasmacytoma (AESOP) syndrome.

In our manuscript we describe the cutaneous manifestations of a rare condition termed Adenopathy and Extensive Skin Patch Overlying Plasmacytoma (AESOP) syndrome. We emphasize the importance of clinically following and subsequently removing the osteolytic tumor to make the diagnosis.

Design and Implementation of Survey Quality Control System for Qatar's First National Mental Health Survey: Case Study.

BACKGROUND: All World Mental Health (WMH) Surveys apply high standards of data quality. To date, most of the published quality control (QC) procedures for these surveys were in relation to face-to-face interviews. However, owing to the social restrictions that emerged from the COVID-19 pandemic, telephone interviews are the most effective alternative for conducting complex probability-based large-scale surveys. OBJECTIVE: In this paper, we present the QC system implemented in the WMH Qatar Survey, the first WMH Survey conducted during the COVID-19 pandemic in the Middle East. The objective of the QC process was to acquire high data quality through the reduction of random errors and bias in data collection. METHODS: The QC design and procedures in this study were adapted to the telephone survey mode in response to the COVID-19 pandemic. We focus on the design of the QC indicator system and its implementation, including the investigation process, monitoring interviewers' performance during survey fielding and applying quality-informed interventions. RESULTS: The study team investigated 11,035 flags triggered during the 2 waves of the survey data collection. The most triggered flags were related to short question administration duration and multiple visits to the same survey questions or responses. Live monitoring of the interviews helped in understanding why certain duration-related flags were triggered and the interviewing patterns of the interviewers. Corrective and preventive actions were taken against interviewers' behaviors based on the investigation of triggered flags per interviewer and live call monitoring of interviews. Although, in most cases, the interviewers required refresher training sessions and feedback to improve their performance, several interviewers discontinued work because of low productivity and a high number of triggered flags. CONCLUSIONS: The specific QC procedures implemented in the course of the WMH Qatar Survey were essential for successfully meeting the target number of interviews (N=5000). The QC strategies and the new indicators customized for telephone interviews contributed to the flag investigation and verification process. The QC data presented in this study shed light on the rigorous methods and quality monitoring processes in the course of conducting a large-scale national survey on sensitive topics during the COVID-19 pandemic.

Triage in Mohs micrographic surgery.

Mohs micrographic surgery can be unpredictable with respect to the level of difficulty of individual cases, especially when pre-operative information is limited. In a retrospective study, Sahai and Walling found complex tumors as defined by requiring four or more stages to clearance to be associated with: recurrent tumors, basal cell carcinoma (BCC) with aggressive histology, tumors with a pre-operative size greater than 1 cm and tumors on the nose.1 The authors created a simplified system for "triaging" Mohs surgery cases in order to predict case complexity and, thus, be better able to manage the scheduling of those cases. Data gathered from 12 months of utilizing this system was used to validate the system's ability to predict case complexity with respect to number of stages for tumor clearance and complexity of reconstruction.

A Case of Cutaneous Leishmaniasis guyanensis Mimicking Otitis Externa.

Cutaneous leishmaniasis typically presents as a painless papule progressing to an ulcer or plaque. In this case study of the ear, the disease manifested as a small painful bump progressing into redness and swelling about the ear with purulent drainage. After multiple oral/intravenous antipseudomonal, antistaphylococcal, and antifungal treatments, there was no improvement. The skin progressed to an erythematous plaque and hemorrhagic ulcer; punch biopsy and speciation revealed Leishmaniasis guyanensis. The patient was switched to a seven-dose course of intravenous L-amphotericin B (visceral leishmaniasis protocol). Within 21 days, pain and edema resolved and the ulcers healed. Three-month follow-up demonstrated no recurrence. Further studies are needed to evaluate the use of L-amphotericin B in Leishmaniasis guyanensis.
