Retrospective analysis shows the cost of Mohs surgery decreases when adjusted for medical inflation.

BACKGROUND: Mohs surgery (MS) is the gold standard for treating nonmelanoma skin cancers in cosmetically sensitive areas. OBJECTIVE: To investigate MS costs over time when adjusting for medical inflation while considering the perspective of patients, payers, and health care systems. METHODS: A retrospective claim analysis using data from the International Business Machines MarketScan Commercial Claims and Encounters Database from 2007 through 2019 was performed. A query of the database for any instance of a MS-specific Current Procedural Terminology (CPT) code in adults (17311, 17312, 17313, 17314, and 17315) was conducted. Aggregate data per claim regarding coinsurance, total cost, deductible, copay, and insurance payout were provided for each CPT code annually. RESULTS: The total adjusted cost per claim decreased significantly (P < .001) for 4 of the 5 MS-specific CPT codes between 2007 and 2019: 17311 (-25%), 17312 (-15%), 17313 (-25%), and 17314 (-18%). The patient's adjusted out-of-pocket expense increased significantly (P < .0001) for 4 of the 5 MS-specific CPT codes: 17311 (33%), 17312 (45%), 17313 (34%), and 17314 (43%). CONCLUSION: Among the 4 most used MS-specific CPT codes (17311, 17312, 17313, and 17314), the total cost per claim decreased and the patient's out-of-pocket expense increased from 2007 to 2019.

Second-Intention Healing in Mohs Micrographic Surgery: A Single-Center Academic Experience.

OBJECTIVE: To describe the trends in second-intention healing (SIH) use at a single Mohs micrographic surgery (MMS) dermatology clinic and assess outcomes and patient satisfaction. METHODS: The authors conducted a single-center, retrospective study of patients who underwent MMS from November 2012 through November 2018. Data obtained for each patient included sex, age, tumor characteristics, number of MMS stages, final defect size, and postoperative complications. Patient satisfaction of SIH was retrospectively assessed by telephone survey. RESULTS: Providers used SIH in 22% of all MMS cases (n = 159/718). It was most commonly used for defects located on the nose, ear, temple, and periocular region. The average defect size and number of MMS stages for tumor clearance were 1.3 cm and 1.5 stages, respectively. Overall, low rates of postoperative complications were observed, and 95% of patients reported optimal or acceptable levels of satisfaction. CONCLUSIONS: This study supports the idea that SIH is a safe, effective alternative for wound management and may have broader practice indications than those traditionally proposed.

Mohs Micrographic Surgery Versus Wide Local Excision in the Treatment of Merkel Cell Carcinoma: A Systematic Review.

BACKGROUND: Merkel cell carcinoma (MCC) is an aggressive neoplasm with high rates of recurrences. Current guidelines recommend wide local excision (WLE) with 1 to 2 cm margins. However, Mohs micrographic surgery (MMS) offers a potential advantage over WLE because of its ability of sparing healthy tissue and assessing 100% of margins. OBJECTIVE: To systematically evaluate the surgical modalities for the treatment of MCC. MATERIALS AND METHODS: Eligible articles were identified using MEDLINE, Scopus, EMBASE, and Cochrane Library. All available studies investigating surgical treatment of MCC with WLE or MMS were considered. RESULTS: Forty studies met the inclusion criteria. Thirty-one studies described patients treated with WLE, 3 with MMS, and 6 with either WLE or MMS. Subgroup analysis of Stage I MCC showed recurrence rates similar in both surgical modalities with local recurrence rate of 6.8% for WLE versus 8.5% for MMS (p = .64) and a regional recurrence rate of 15.2% for WLE versus 15.3% for MMS (p = .99). CONCLUSION: Overall WLE cases were at a higher stage at presentation. Subgroup analysis showed that MMS is not inferior to WLE excision for the treatment of Stage I MCC and is a reasonable option for anatomic locations where tissue sparing is important.

Periorbital and Globe Injuries in Pediatric Orbital Fractures: A Retrospective Review of 116 Patients at a Level 1 Trauma Center.

STUDY DESIGN: Retrospective chart review of pediatric and globe injuries associated with orbital fractures. OBJECTIVE: Our study seeks to examine these injuries and their association with orbital fractures at our trauma center to gain a better understanding of how to approach pediatric patients with orbital fractures. METHODS: A retrospective review of all facial fractures in pediatric patients at an urban level 1 trauma center was performed for the years 2002 to 2014. Patient demographics were collected, as well as orbital fracture location, mechanism of injury, concomitant injuries, ophthalmologic documentation, imaging, and perioperative records. RESULTS: One hundred sixteen pediatric patients over a 12-year period sustained an orbital fracture. The orbital floor was the most commonly fractured orbital bone in our series (60%). Thirty-four (30%) of the pediatric patients with orbital fractures had documented periorbital and/or globe injuries at the time of presentation. The most common periorbital injury was entrapment related to orbital floor fractures. Significant eyelid lacerations were present in seven patients, with five of these patients had canalicular injuries and two had canthal malposition. Five pediatric patients presented with traumatic optic neuropathy. Two patients had ruptured globes requiring enucleation. CONCLUSIONS: Periorbital soft tissue and globe injuries associated with orbital fractures occurs in a substantial number of pediatric patients. There are no guidelines for treatment of these type of injuries in the pediatric population. Further research should be performed to better understand the appropriate management of periorbital injuries in conjunction with surgical management of the orbital fractures.

Psoriatic Alopecia in a Patient With Crohn Disease: An Uncommon Manifestation of Tumor Necrosis Factor α Inhibitors.

Tumor necrosis factor α (TNF-α) inhibitors are used to treat multiple inflammatory diseases including rheumatoid arthritis, inflammatory bowel disease, and psoriasis, among others. This family of medications can cause various side effects, some as common as injection-site reactions and others as rare as the paradoxical induction of psoriasiform skin lesions. Alopecic plaques recently have been described as an uncommon adverse effect of the TNF-α inhibitors adalimumab and infliximab. We present the case of a 12-year-old girl treated with adalimumab for Crohn disease who developed an alopecic crusted plaque on the scalp 6 months after increasing the dose of the medication. Biopsies, special stains, and sterile cultures yielded a diagnosis of psoriatic alopecia secondary to TNF-α inhibitor. A literature review for similar cases found 24 additional patients presenting with similar findings, of which only 6 were part of the pediatric population.

Differentiation of Basal Cell Carcinoma and Trichoepithelioma: An Immunohistochemical Study.

ABSTRACT: Basal cell carcinoma (BCC) is the most common malignancy of the skin. It is an epithelial neoplasm with origin in the precursor cells of the interfollicular epidermis. Even though it has low metastatic potential, delay in management may lead to local destruction and morbidity. In contrast, trichoepithelioma (TE) is a benign tumor originating from the outer root sheath of the hair follicle. Similar to BCC, TE tends to affect the head and neck region. Both neoplasms may exhibit clinical and histopathological similarities, making them prone to misdiagnosis. Multiple immunomarkers have been used to distinguish among these entities, but so far, no single agent or combination of agents appear to be neither sensitive nor specific enough to differentiate between them. This study was divided into 2 parts. First, 17 cases of BCC and 14 cases of TE were stained with androgen receptor and bcl-2. Then, 27 cases of borderline/equivocal of BCC and 13 cases of borderline/equivocal TE were stained with the same protocol. Sensitivity and specificity were calculated for each individual immunomarker and for the combination of them. Androgen receptor positivity was 100% specific for BCC and borderline/equivocal BCC, whereas bcl-2 diffuse staining pattern demonstrated a sensitivity of 82.4% for BCC and 88.9% borderline/equivocal BCC. When both immunomarkers were combined, the sensitivity for BCC decreased (70.6%) but the specificity remained high (100%). Similarly, the sensitivity for borderline/equivocal BCC was 55.6%, whereas the specificity was 100%. Although moderately sensitive, combining both immunomarkers showed an excellent specificity to discriminate between BCC and TE.

Folliculocystic and Collagen Hamartoma: A Distinct Hamartoma Associated With Tuberous Sclerosis Complex.

ABSTRACT: Tuberous sclerosis complex (TSC) is a neurocutaneous disease characterized by cutaneous and extracutaneous hamartomas. Dermatologic evaluation is critical for early diagnosis because mucocutaneous manifestations account for 4 of 11 major and 3 of 6 minor diagnostic criteria. Folliculocystic and collagen hamartoma (FCCH) is a recently described entity associated with TSC. We herein describe the case of a 28-year-old woman with a history of TSC who presented with a scalp lesion present since childhood. Physical examination revealed a solitary, well-circumscribed exophytic tumor over the occipital scalp measuring 9 × 8 cm and covered with comedones and cyst-like structures. Biopsy of the lesion demonstrated thickening of the collagen bundles throughout the dermis, concentric perifollicular and perivascular fibrosis, an increased number of dilated vessels, and keratin-filled cysts lined by the infundibular epithelium. Clinicopathologic correlation was diagnostic for FCCH. The patient was referred for surgical excision. In addition, we review 11 other cases of FCCH previously reported in the literature.

Treatment of erythrodermic psoriasis with biologics: A systematic review.

BACKGROUND: Biologic medications for plaque psoriasis have been used to treat erythrodermic psoriasis (EP). Since the guidelines for management of EP were published, new biologic medications have been approved for the treatment of plaque psoriasis. OBJECTIVE: To analyze the evidence of biologic medications in the treatment of EP based on response and tolerability. METHODS: A comprehensive search was conducted with the PubMed, Cochrane Library, Embase, and Scopus databases through December 31, 2018. Studies reporting 1 or more cases of EP, defined as >75% body surface area involvement, in patients aged ≥18 years treated with biologics were included. Baseline Psoriasis Area and Severity Index score, score improvement, and adverse events were documented. Adequate response to treatment was defined as Psoriasis Area and Severity Index ≥50. RESULTS: Included were 43 articles, yielding a total of 179 patients. Most patients responded at some point during treatment, with a higher level of evidence for infliximab, ustekinumab, ixekizumab, and guselkumab. Infection was the most common adverse event (n = 35). LIMITATIONS: Data are limited to case reports, case series, and uncontrolled studies. CONCLUSION: Patients with EP treated with biologics demonstrated positive responses and treatment was well-tolerated, with a weak recommendation and limited quality of evidence in favor of infliximab, ustekinumab, ixekizumab, and guselkumab.

Biological therapy for pustular psoriasis: a systematic review.

BACKGROUND: The anecdotic evidence of the benefits from biologic agents for psoriasis is extensive. However, data on the efficacy of biologic agents for pustular psoriasis are limited. METHODS: To update the data on the efficacy and safety of biologic agents for the management of pustular psoriasis. A systematic review of published data regarding biologic therapies on PubMED database, used in the management of pustular psoriasis from 2012 was undertaken. RESULTS: A total of 209 articles were identified, and 43 articles were selected for inclusion. TNF-α inhibitors were used in 205 patients, and 86 patients received ustekinumab, secukinumab, brodalumab, ixekizumab and IL-1 inhibitors. Overall response was favorable for most modalities. No serious adverse events were reported. Inconsistent measures of treatment response and study variability limited the overall evaluation of data. CONCLUSIONS: Infliximab and ustekinumab have the most evidence of efficacy and safety for the treatment of pustular psoriasis. Recent evidence supports the use of IL-17 antagonists. Prospective controlled and comparative trials are needed to further explore the efficacy and safety of biologic agents in order to establish objective recommendations for the management of this challenging condition.

Stevens-Johnson syndrome and toxic epidermal necrolysis: a retrospective descriptive study.

BACKGROUND: Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare and potentially life-threatening mucocutaneous reactions. Given their rarity, limited cohort studies have been done. The aim of this study is to evaluate and compare the demographics, etiology, management, clinical and laboratory characteristics, complications, and outcome of SJS/TEN patients seen by the inpatient dermatology service at the University of Puerto Rico. METHODS: A retrospective review of 30 cases with identified diagnosis of SJS, overlap SJS/TEN, or TEN who were consulted to the Dermatology Department of the University of Puerto Rico from 2006 to 2017. RESULTS: A total of 24 adult and six pediatric cases were reviewed. Females were predominant with a female to male ratio of 1.3 : 1. The most frequent offending drugs identified were antibiotics (56.7%), anticonvulsants (23.3%), and nonsteroidal anti-inflammatory drugs (NSAIDs) (16.7%) with the most frequent antibiotic identified being trimethoprim/sulfamethoxazole (23.3%). Seventy percent of patients experienced at least one complication, most often of infectious etiology (80.1%). During hospital course, 73% received pharmacologic therapy (23% received IVIG alone, 17% received steroids alone, and 33% both) versus 27% which received only supportive care. Mortality rate in this study was 13.8%. When comparing SCORTEN at day one of admission, deceased cases had a mean SCORTEN at day 1 of 4.0, while survivors had an average of 1.54 (P < 0.001). CONCLUSION: Antibiotics followed by anticonvulsants were the most frequently offending drugs identified within this study.

Non-Melanoma Skin Cancer Tumor's Characteristics and Histologic Subtype as a Predictor for Subclinical Spread and Number of Mohs Stages required to Achieve Tumor-Free Margins.

OBJECTIVE: To describe the behavior of non-melanoma skin cancer (NMSC) based on tumor's characteristics. METHODS: A total of 219 of NMSC were analyzed via a retrospective medical chart review. The data obtained from each record included but was not limited to: number of Mohs micrographic surgery (MMS) stages required for tumor clearance, defect size, repair type and size according to the neoplasm's histopathologic subtype. RESULTS: The mean number of stages required to clear morpheaphorm/infiltrative and micronodular basal cell carcinomas (BCCs) (n= 34) was 2.03, while the nodular and superficial BCCs (n= 125) needed a mean of 1.56 stages (p value= .034). Of the tumors located on a high-risk zone, 59.6% required two or more stages to be cleared while 67.7% of the lesions on a non-high risk zone were cleared with one stage (p value = 0.001). Recurrent tumors required a mean 2.22 MMS stages to be cleared, whereas primary tumors required a mean 1.61 stages (p value= .006). CONCLUSION: Subclinical spread was seen in morpheaform/infiltrative and micronodular BCC histologic subtypes, recurrent tumors, and tumors in high-risk locations. These could help predict aggressive tumor behavior and optimize surgical planning.
