RESUMO
BACKGROUND: Periorbital rejuvenation is a common cosmetic concern. A fractional thermomechanical skin rejuvenation system was developed to offer clinical improvements from direct heat transfer. OBJECTIVE: A prospective study evaluated the efficacy and safety of the device for periorbital fine lines and wrinkles. MATERIALS AND METHODS: Subjects with moderate-to-severe periorbital rhytides were enrolled and underwent 4 monthly treatments with a novel device using thermomechanical fractional injury (Tixel 2; Novoxel, Netanya, Israel). RESULTS: Fifty-one subjects were enrolled. Mean age was 56.8 years, and 88.2% were women. Fitzpatrick skin Types I to IV were included. For Fitzpatrick Wrinkle Classification System (FWCS), mean baseline score was 5.7. Per investigator, there was a mean 2.0-grade improvement in FWCS at 3-month follow-up ( p < .0001). Per 3 blinded physician raters, there was a mean improvement of 2.2 ( p < .0001), 2.0 ( p < .0001), and 1.2 ( p < .0001) in FWCS at 3-month follow-up. Each of the raters correctly identified posttreatment images for 87.5%, 77.1%, and 75.0% of subjects. At least 2 raters agreed on grading 83.3% of subjects as responders. There were no severe adverse events. Subjects experienced minimal pain and downtime. CONCLUSION: A novel device using thermomechanical fractional injury was demonstrated to be safe and effective in the treatment of periorbital rhytides.

BACKGROUND: Pincer nail deformity (PND) is a common toenail disorder characterized by transverse over-curvature of the nail plate. It can cause severe pain, chronic inflammation, and recurrent infections. Both conservative and surgical treatment options carry different disadvantages of limited efficacy, high recurrence rate, and poor cosmetic outcome. The study aimed to evaluate the safety and effectiveness of carbon dioxide (CO2) laser matricectomy for the treatment of PND. METHODS: The database of the laser unit of a tertiary medical center was retrospectively searched for all patients who were diagnosed with PND in 2016-2022 and treated with lateral and/or medial matricectomy using CO2 laser. Clinical and follow-up data were collected from the medical files. Results: The cohort included 19 patients (5 male, 14 female) who underwent 25 partial matricectomies during the study period (some patients had more than one diseased nail). All procedures were successful, with no intraoperative or postoperative complications. There was one documented recurrence at 7 months after treatment. CONCLUSION: Partial CO2 laser matricectomy is safe and effective for the treatment of PND. J Drugs Dermatol. 2023;22(11):1099-1102 doi:10.36849/JDD.7574.

Hair removal with lasers and intense pulsed light (IPL) is considered safe. However, data on the efficacy and safety of these procedures specifically in the pediatric population remain sparse. To determine the efficacy and safety of lasers and IPL for hair reduction in children and adolescents, a systematic review was conducted of original studies evaluating hair removal with lasers or IPL in patients aged less than 18 years. Primary outcome measures were efficacy and safety of treatment. The literature review yielded 2 retrospective cohort studies and 11 case reports/case series including a total of 71 patients aged 9 months to 17 years. Diagnoses ranged from localized lumbosacral to generalized hypertrichosis. Six treatment modalities were evaluated: alexandrite, Nd:YAG, Q-switched Nd:YAG, ruby, and diode lasers and IPL. Only one of the cohort studies (n = 28), using the ruby laser, provided efficacy data. The results showed a 63% hair loss in 89% of patients after completion of treatment, although partial regrowth was evident during 6 to 32 weeks of follow-up. Most of the case reports and case series (10/11) reported significant hair reduction following laser and IPL treatments. None of the patients experienced scarring or dyspigmentation. Some kind of pain management was necessary in 65% of patients; 25% required general anesthesia. On the basis of the limited available data which consisted primary of case reports and case series, lasers and IPL might be effective for pediatric hair reduction. Recurrence following treatment may be higher in children than adults, and pain control may be a limiting factor.

BACKGROUND: Occupational contact dermatitis may progress to a chronic course with an unfavorable prognosis. Dupilumab has been shown to be effective as a treatment for moderate-to-severe atopic dermatitis as well as other types of dermatitis. OBJECTIVES: The aim of the study was to describe cases of chronic recalcitrant occupational contact dermatitis treated with dupilumab and with long-term follow-up. METHODS: A retrospective review of 6 patients treated with dupilumab for chronic occupational contact dermatitis for periods of up to 30 months was performed. RESULTS: All 6 patients had a positive and sustainable response, with dermatitis clearance and the ability to sustain work tasks. CONCLUSIONS: We report a case series of atopic and nonatopic workers with occupational chronic contact dermatitis who failed to achieve remission under various systemic modalities but did so using dupilumab. We suggest considering dupilumab treatment for recalcitrant occupational contact dermatitis.

BACKGROUND: Bullous Pemphigoid (BP) is an autoimmune subepithelial bullous disease. Several reports suggested an association between BP and scabies. OBJECTIVE: We aimed to evaluate whether an association between BP and scabies exists. METHODS: This is a retrospective matched case-control study. We retrospectively identified BP patients treated in our clinic between January 1, 2009, and December 31, 2016. Each patient was assigned to 3 control subjects (matched by age and sex) treated in our clinic, not due to BP. The study group was examined for a scabies diagnosis within the 3 years prior to BP diagnosis; the control group was examined for a scabies diagnosis 3 years prior to its first visit in our clinic. RESULTS: Fifteen out of the 87 (17.2%) BP patients were diagnosed with scabies within the 3 years prior to their initial BP diagnosis, compared to only 4.2% (11 out of 261) among the control group. The odds ratio of scabies history was 4 times higher among BP patients compared to the control group (OR=4.23; 95% CI: 1.50–11.91, P=0.007). LIMITATIONS: A retrospective study design. CONCLUSIONS: An association between scabies diagnosis and BP is demonstrated in our study. J Drugs Dermatol. 2022;21(9):1009-1011. doi:10.36849/JDD.4900.

The sequential application of fractional ablative/10,600 nm/CO2 followed by 1570 nm non-ablative laser treatment might produce better results than applying either laser treatment alone. However, histological data regarding the safety of this combination is lacking. This study aimed to assess and compare clinical effects, histological tissue damage, and wound healing after monochromatic and sequential fractional laser treatments. In this prospective porcine model study, three adult female pigs were each irradiated using three different wavelengths: (a) monochromatic fractional ablative CO2 laser; (b) monochromatic fractional non-ablative 1570 nm laser; (c) sequential fractional 10,600 nm/CO2 followed by 1570 nm laser treatment. There were six power levels in the monochromatic 1570 nm laser, five in the 10,600 nm/CO2, and five in the sequential treatment. The immediate skin reaction (ISR), crusting and adverse effects, was evaluated across different time points throughout the healing process. Wound biopsies were taken at immediately after (0) and at 3, 7, and 14 days after irradiation. Depth and width of craters, and width of coagulation zone were measured and compared. Similar ISR and crusting score values were obtained following the monochromatic and sequential irradiation in a similar dose-response manner. During 14 days of follow-up, the skin looked intact and non-infected with no signs of necrosis. The mean depth and width of craters were comparable only at the maximal energy level (240 mJ) of CO2 laser, with the coagulation size greater after the sequential treatment. In histology, a similar wound healing was evident. On day 3, crusts were observed above all lesions as was epithelial regeneration. The sequential irradiation with 10,600 nm/CO2 and 1570 nm lasers did not pose any additional risk compared to the risk of each laser alone.

Actinic keratoses are common cutaneous lesions with a potential to progress to invasive squamous cell carcinoma. Therefore, treatment is crucial. The Tixel® is a noninvasive thermomechanical device designed to transfer heat to the upper dermis in a controlled manner according to a predetermined setting. This study aimed to evaluate the safety and efficacy of a thermomechanical fractional skin resurfacing technology for the treatment of facial and scalp actinic keratoses. A prospective, open-label, before-after study was conducted in a tertiary medical centre from May 2020 to April 2021. Patients presenting with facial/scalp actinic keratoses of mild-to-moderate thickness underwent 2 or 3 Tixel treatments (depending on clinical improvement), 3-4 weeks apart. The reduction in lesion count and overall improvement in appearance were assessed by clinical examination and digital photography. Findings were compared between baseline and follow-up at 3 months after the last treatment session. Patient satisfaction was evaluated by questionnaire, and adverse effects were documented. A total of 20 patients participated in the study. All completed 2-3 treatments and follow-up visits. Assessment of digital photographs was performed by 2 assessors blinded to the timepoint at which each photo was taken (before or after treatment). The average number of lesions at baseline was 9.8 (± 4.8) and the mean reduction in lesion count was 7.9 (± 4.4) (80.6%). Complete clearance was observed in 31.6% of patients. No adverse effects were noted during treatment and follow-up. Most patients reported being "very satisfied" or "satisfied" with the treatment results (85%) and experience (95%). Treating facial and scalp actinic keratoses with the Tixel device was found to be effective and safe.

Introduction: Whether individuals with atopic diseases have a different risk of contact allergy compared to those who are non-atopic is controversial and data are conflicting. Aim: To explore the association between atopy and allergic contact dermatitis (ACD). Material and methods: This retrospective cross-sectional study included 301 patients referred to a tertiary clinic to evaluate ACD. Demographic details including personal and familial mucosal or cutaneous atopic status were recorded. Patch tests were tailored to their clinical presentations and relevant exposures. Results: At least 1 positive patch test reaction was observed in 177 patients (59% of the study cohort), of which 52% had a history of atopic diseases, compared with 44% of patients with a negative patch test result (p = 0.2). Additionally, 147 patients had an atopic background, of which 92 (62%) had ≥ 1 positive patch test result, compared with 55% of non-atopic patients (p = 0.2). Nickel sulphate was the most common contact allergen (13.4% of the patch test reactions). Conclusions: We identified a positive tendency for atopic diseases among individuals with ACD and vice versa. Our study supports the aggregate data from previous studies despite the non-significant differences between the study and control groups. However, further research performed in larger populations of patients is necessary to evaluate the real association between atopy and ACD on a solid basis. Our results indicate the necessity of systematic patch testing in patient setups with atopic background and chronic dermatitis.
RESUMO
Cutaneous viral warts (CVW), caused by human papillomavirus, often have a self-limited course. However, some patients experience a recalcitrant disease despite treatment. Retinoids are considered the mainstay of therapy in many dermatologic diseases. Data on their use for viral warts are limited. To systematically review the published evidence on the efficacy and safety of retinoids for the treatment of CVW. A systematic review and meta-analysis of topical or systemic retinoid treatment for CVW was performed in accordance with the PRISMA statement. The primary outcome was clinical response; secondary outcomes were recurrence rate and adverse events. Fourteen publications including 399 patients treated exclusively with retinoids (65% topical, 35% systemic) were evaluated. The complete response rate was 64% (95% CI, 46-78%; I2 =80%) for topical treatment and 61% (95% CI, 44-76%; I2 =69%) for systemic treatment. The most common side effects were irritant contact dermatitis and cheilitis, respectively. Relapse rates were 6% and 17%, respectively. The reviewed studies were considerably heterogenous and most lacked a control group. Both topical and systemic retinoids are effective and safe as monotherapy for CVW. Further studies are required to determine their exact role in this setting.

BACKGROUND: Genital warts, caused by the human papillomavirus, are a common sexually transmitted disease. The warts can regress spontaneously or exhibit a persistent clinical course. Various therapeutic modalities are available, yet none is curative, and there may be recurrences. Retinoids are considered the mainstay of therapy in many dermatologic diseases. Data on their use for genital warts are limited. OBJECTIVE: To systematically review the published evidence on the efficacy and safety of retinoids for the treatment of genital warts. METHODS: A systematic review and meta-analysis of all publications evaluating topical or systemic retinoids for the treatment of genital warts was performed. The primary outcome was complete response (CR); the secondary outcomes were recurrence rate and adverse events. RESULTS: Six publications were evaluated, three randomized controlled trials and three prospective cohort studies, including a total of 141 patients with genital warts treated exclusively with retinoids (90% with isotretinoin). CR rates were 100% for systemic etretinate (3 out of 3 patients, 95% CI 28-81%) and 56% for isotretinoin (95% CI 28-81%; I2 = 84%). Topical etretinate did not induce CR. The most common side effect of topical agents was irritant contact dermatitis (36%) and that of systemic agents mucocutaneous disorders (80%). The relapse rate was 12% for oral isotretinoin and was unavailable for the other modalities. CONCLUSIONS: Current data suggest that unlike topical retinoids, systemic retinoids are an effective and safe treatment for genital warts. Further studies are required to determine their specific role and the most effective regimen for each derivative.

BACKGROUND: There are three major types of genetic cutaneous porphyrias (GCP): erythropoietic protoporphyria (EPP), variegate porphyria (VP), and hereditary coproporphyria (HCP). Scarce data are available regarding their impact on patients' quality of life in the Mediterranean region. PURPOSE: To describe the cutaneous features of GCP in Israel. METHODS: An established nationwide cohort of patients with GCP diagnosed during 1988-2019 was surveyed by telephone for cutaneous features of GCP. Impact on quality of life was assessed using the Dermatology Life Quality Index. RESULTS: Of the 95 patients with GCP, 71 (75%) completed the survey (21 HCP; 40 VP; 10 EPP). All EPP patients reported cutaneous symptoms compared with 58% of VP and 5% of HCP (P < .001). Mean age at symptom onset was 7 ± 6 years in EPP and 25 ± 15 years in VP (P < .001). Photosensitivity was the most common symptom in EPP (90%). In VP photosensitivity (52%), blistering (52%) and scarring (74%) were all common symptoms. In both VP and EPP, the dorsal hands/forearms were the most affected regions (≥96%), and in ≥ 78%, symptoms occurred on an almost daily basis. All EPP patients changed their lifestyle due to cutaneous symptoms vs 57% in VP. Major effect on quality of life was observed among EPP patients compared with a moderate effect in VP. No treatment was effective in EPP, while phototherapy and moisturizers were effective in 5 of 7 (71%) VP patients. CONCLUSION: This study sheds light on the cutaneous features of the GCP, which have a substantial effect on patients' quality of life.

Solar urticaria is a well-recognized photodermatosis, sometimes accompanied by angioedema. However, isolated solar angioedema (ISA) is a rare and unrecognized entity. The purpose of our work was to systematically review the available data on ISA. Therefore, a systematic review of studies evaluating ISA was performed. Additionally, a case of a 21-years-old patient from our photodermatosis service is presented. The search yielded 421 publications, with 3 eligible for review. Together with our case, 5 cases were included overall. All patients were female. Four out of 5 patients first experienced ISA at childhood or early adulthood (age range 6-22 years). UVA photoprovocation was positive in the 3 out of the 4 patients who were tested. Improvement was noted following NB-UVB hardening (2 out of 5 patients) or a short course of oral prednisone (3 out of 5 patients) combined with regular sunscreen application. To conclude, ISA is an extremely rare entity, although it may be underdiagnosed due to lack of awareness. The clinician must consider ISA in the differential diagnosis of angioedema since it can have a detrimental effect on quality of life. Besides sun avoidance, there is no consensus regarding treatment.

BACKGROUND: Inherited genetic erythropoietic protoporphyria (EPP) is characterized by a photosensitive rash that emerges during infancy or early childhood. Acquired EPP can erupt at any age, even during adulthood, and is associated with hematological disorders. A third, less-studied type of EPP is also inherited but appears later in life (during adulthood). PURPOSE: To evaluate the characteristics of inherited genetic late-onset (IGLO) EPP. METHODS: A systematic comprehensive search of the literature was conducted using PubMed, Google Scholar, ScienceDirect, and clinicaltrials.gov databases. Studies describing patients with IGLO EPP were included. Additionally, we present an index case of a patient, treated at our clinic in whom inherited genetic EPP was diagnosed at age 21 years. RESULTS: The search yielded 1514 citations. Five publications were eligible for review. Along with our case, 7 patients (4 males) were included in the analysis. Mean age at disease onset was 34.2 years (range 18-69, median 30). Most patients presented with mild pruritus and rash in a photosensitive distribution. Mean level of free erythrocyte protoporphyrin IX (FEP) was 8.6 µmol/L. A mutant ferrochelatase gene (FECH) in trans to a hypomorphic FECH allele was found in 3 of the 4 patients who underwent genetic testing. CONCLUSION: We describe the distinct features of IGLO EPP. This work emphasizes that a diagnosis of inherited genetic EPP should not be ruled out in adults with new-onset photosensitive manifestations.

Post-surgical facial scars are often associated with unaesthetic outcome. Treatment of these scars using various lasers could be beneficial; however, the use of the Q-switched fractional (QSF) 1064-nm neodymium-doped yttrium aluminum garnet (Nd:YAG) laser has yet to be evaluated for this indication. Our objective was to determine the safety and efficacy of a QSF-Nd:YAG laser for the treatment of post-surgical facial scars. Eleven (5 male, 6 female) patients who underwent facial surgery with significant scarring were treated using the QSF-Nd:YAG laser. Scars were exposed to 600-1200 mJ/stacked pulses (12-24 mJ per pixel), emitted at a rate of 10 Hz for up to 2 passes per treatment session, receiving overall 3-6 treatments. Patient follow-up was 3 months. Scars' photographs were blindly assessed by two dermatologists, who graded them on a scale of scar severity from 1 to 5 (1 = least severe, 5 = most severe) before and after treatment. A blinded before/after recognition of these photographs was also performed. Patient satisfaction was assessed 3 months post-treatment and graded on a scale of 1-5 (1 = not satisfied, 5 = very satisfied). Pain perception and adverse effects were also evaluated. Patients demonstrated a decrease in scar severity score by a mean of 1.57 points (p = 0.0005). A blinded before/after recognition was correct in 86.5% of the cases. Pain and adverse effects were mild and transient. Patient satisfaction was high (4.2). QSF-Nd:YAG laser is a safe and effective modality for the treatment of post-surgical facial scars.

The pulsed dye laser (PDL) is the standard treatment for port-wine stains (PWS). Maximal improvement occurs after multiple treatment sessions; however, the optimal treatment interval has yet to be determined. The aim of this study was to review whether there is an association between PDL treatment interval and outcome of PWS. Six databases were searched by three reviewers for publications investigating treatment of PWS with PDL. The 75% improvement rates (75IR) were extracted for quantitative analysis. Meta-regression was used to investigate the association between treatment intervals and 75IR. The systematic review included 1 RCT and 33 cohort studies (7 prospective cohorts and 26 retrospective cohorts), with a total of 3777 patients. The pooled 75IR was 37% (95% CI 29-45%; I2 = 95%). Light Fitzpatrick skin type (p = 0.04), facial anatomic location (p = 0.01), and young age (p = 0.008) were associated with 75IR. In an unadjusted (p = 0.42) and multivariable adjusted (p = 0.98) meta-regression, no association was found between time interval between treatments and 75IR. These results persisted in a sensitivity analysis of studies with a mean patient age of ≤ 1. The majority of included studies were heterogeneous and retrospective. Based on cohort studies of low-to-moderate quality, time intervals between PDL treatments are not associated with PWS outcome.

Photodynamic therapy (PDT), traditionally used in patients with nonmelanoma skin cancer, has been found to be effective for various inflammatory skin conditions. Daylight-activated PDT (DL-PDT), in which the sun serves as the light source, is substantially less painful than conventional PDT. This study aimed to determine the safety and efficacy of DL-PDT in a series of patients with chronic hand eczema (CHE). A proof-of-concept prospective design was used. Eight patients diagnosed with CHE at a tertiary dermatology clinic underwent DL-PDT. The first treatment was administered at the clinic and subsequent treatments (up to four total) were self-administered at home at 2-week intervals. Outcome was evaluated with the Investigator Global Assessment (IGA; score 0-4), Dermatology Life Quality Index (DLQI; score 0-24), and blinded review of clinical photographs (graded on a quartile scale by percent improvement). There were six male and two female patients of mean age 35 years. All underwent at least three treatments. The IGA score improved by 2.5 points at 1 month, 2.7 at 3 months, and 2.2 at 6 months post-treatment, and the DLQI score improved by 7.9, 6.6, and 6.1 points, respectively. Clinical photograph grades improved by 2.9 points at 3 months. Side effects were mild and transient. All patients had some degree of recurrence after 6 months of treatment. The self-administered DL-PDT is easy to perform, moderately effective, and safe to use in patients with CHE. Repeated treatments might be required to maintain remission.

INTRODUCTION: Surgery is commonly regarded as the mainstay of treatment of extramammary Paget disease (EMPD); however, nonsurgical approaches have gained popularity in recent years. OBJECTIVES: To review the published evidence for the efficacy and safety of nonsurgical modes of therapy for EMPD. METHODS: A systematic review and meta-analysis of nonsurgical EMPD treatments was performed. The primary outcome was complete response (CR); secondary outcomes were clinical regression by ≥50%, adverse events, and recurrence rate. RESULTS: The systematic review included 43 observational studies (341 patients; 7 prospective cohort studies, 19 retrospective cohort studies, and 17 cases series) evaluating 5 treatment modalities. Imiquimod (13 studies, 110 patients) administered at variable doses ranging from daily to twice weekly for 2-56 weeks demonstrated CR of 54% (95% CI, 40-67%; I2 = 37%) and had a satisfactory safety profile. In 14 heterogeneous studies (122 patients) evaluating photodynamic therapy (PDT), only 36% (95% CI, 22-53%; I2 = 52%) of patients achieved CR. Radiotherapy (12 studies, 67 patients) showed CR of 97%, but was associated with local and systemic side effects. Ablative lasers and topical fluorouracil and calcipotriene lacked adequate evidence of efficacy. CONCLUSIONS: Imiquimod and radiotherapy are the most appropriate nonsurgical modalities for EMPD treatment given their good efficacy and safety profile. PDT has limited efficacy but may be appropriate in selected clinical settings.

BACKGROUND: Erythropoietic protoporphyria (EPP) is a semi-dominantly inherited porphyria presenting with photosensitivity during early childhood. Acquired EPP has been reported; however, data regarding this rare disorder are scarce. PURPOSE: To evaluate the characteristics of acquired EPP. METHODS: A comprehensive search of PubMed, Google Scholar, ScienceDirect, and clinicaltrials.gov databases was performed by three reviewers. Studies describing patients with acquired EPP were included. Additionally, we present an index case of a 26-year-old patient who acquired clinically and biochemically typical EPP in association with myelodysplastic syndrome (MDS). RESULTS: We included 20 case reports describing 20 patients. Most (80%) patients were male of mean age 58 ± 13 years. In all patients, acquired EPP was associated with hematological disease, most commonly MDS (85%) followed by myeloproliferative disease (10%). In 86% of cases, hematological disease led to abnormality or somatic mutation in chromosome 18q (the locus of the ferrochelatase gene). The mean erythrocyte protoporphyrin IX concentration was very high (4286 µg/dL). Most (90%) patients presented with photosensitivity, 20% experienced blistering, and 25% presented with hepatic insufficiency, both uncommon in EPP. In 55% of patients, hematological disease was diagnosed after occurrence of cutaneous symptoms. Beta-carotene led to partial control of symptoms in 5 patients and resolution in another patient. Azacitidine treatment of MDS led to resolution of cutaneous symptoms in three patients. CONCLUSION: We present the distinct features of acquired EPP and highlight that any patient presenting with new-onset photosensitivity, irrespective of age should be evaluated for porphyria.

BACKGROUND: The association between body mass index (BMI) and acne is unclear. OBJECTIVE: To determine the association between BMI and acne in youths. METHODS: A nationwide, population-based, cross-sectional study was conducted in 2002-2015 by using medical data on 600,404 youths during compulsory military service. BMI was measured at age 17 years. Acne was diagnosed by dermatologists. Unadjusted and adjusted odds ratios (aORs) of acne in relation to BMI (stratified into 8 groups) were calculated, with the low-normal group (18.5≤ BMI ≤21.99 kg/m2) serving as the reference. RESULTS: The study included 299,163 males (49.9%) and 301,241 females (50.1%) with a mean age of 18.9 years (standard deviation, 0.6) and 18.7 years (standard deviation, 0.5), respectively, at recruitment. Acne was diagnosed in 55,842 males (18.7%) and 48,969 females (16.3%). The proportion of participants with acne decreased gradually from the underweight to the severely obese group (males, from 19.9% to 13.9%; females, from 16.9% to 11.3%). The findings on multivariable analysis were similar to the unadjusted analysis results, showing the lowest odds of acne in severely obese participants (aOR for males, 0.53; 95% confidence interval, 0.42-0.64; aOR for females, 0.5; 95% confidence interval, 0.37-0.62). The findings persisted in the sensitivity analyses. LIMITATIONS: Information was lacking on potential confounders and acne severity. CONCLUSION: In youths, overweight and obesity are inversely associated with acne in a dose-dependent manner.

BACKGROUND: Disorders of the umbilicus are commonly seen in infancy, including hernias, infections, anomalies, granulomas, and malignancies. Meticulous inspection of the umbilicus at birth might reveal a persisting embryonic remnant, such as an omphalomesenteric duct (OMD), manifested by a variety of cutaneous signs, such as an umbilical mass, granulation tissue, or discharge. OBJECTIVE: To systematically review the available data regarding the presence and management of OMD remnant with cutaneous involvement to suggest a practical approach for diagnosis and treatment. METHODS: A systematic review of the literature evaluating OMD anomalies presenting with cutaneous symptoms was performed. In addition, an index case of an 11-month-old patient is presented. RESULTS: We included 59 publications reporting 536 cases; 97% of the patients whose age was noted were infants (mean age 11 months). In 7.5% of the cases, diagnosis was established only after treatment failure. In 6.4% of patients, nonlethal complications were reported, and in 10.3%, the outcome was death, partly due to delayed diagnosis or mismanagement. LIMITATIONS: Limited quality of the collected data, reporting bias. CONCLUSION: OMD is relatively rare; however, the clinician must consider this remnant while examining patients with umbilical abnormalities because mismanagement could cause severe morbidity and mortality.
