Longitudinal Analysis of Cancer Risk in Children and Adults With Germline PTEN Variants.

Importance: Identifying hereditary cancer predisposition facilitates high-risk organ-specific cancer surveillance and prevention. In PTEN hamartoma tumor syndrome (PHTS), longitudinal studies remain lacking, and there are insufficient data on cancers in children and young adults, as well as individuals with neurodevelopmental disorders (NDD). Objective: To evaluate lifetime cancer risks, including second malignant neoplasms (SMN), among patients with PHTS. Design, Setting, and Participants: Prospective longitudinal cohort study (September 1, 2005, through January 6, 2022). General population risks from the Surveillance, Epidemiology, and End Results database. Patients with PHTS, molecularly defined as carrying germline PTEN variants, were accrued from community and academic medical centers throughout North America, South America, Europe, Australia, and Asia. Data were analyzed from July 2022 to February 2023. Exposures: Review of physical and electronic medical records, and follow-up through clinical visits or telephone interviews. Main Outcomes and Measures: Lifetime cancer risks in PHTS relative to the general population. Results: A total of 7302 patients were prospectively accrued, 701 of whom had germline PTEN variants (median [IQR] age at consent, 38 [12-52] years; 413 female patients [59%]). Longitudinal follow-up data could be obtained for 260 patients (37%), with a median (IQR) follow-up of 4 (2-8) years. Of the 701 patients, 341 (49%) received at least 1 cancer diagnosis, with 144 (42%) of those having SMN. The study found significantly elevated lifetime risks for breast (91%), endometrial (48%), thyroid (33%), kidney (30%), and colorectal cancers (17%), as well as melanoma (5%). Cancer diagnoses were also observed in children and young adults with PHTS (15%) and in patients with PHTS with neurodevelopmental disorders (11%). Elevated risks (P < .001) of thyroid (age-adjusted standardized incidence ratios [SIR], 32.1; 95% CI, 26.0-39.0), kidney (SIR, 26.5; 95% CI, 18.8-36.3), endometrial (SIR, 26.0; 95% CI, 19.5-34.1), breast (SIR, 20.3; 95% CI, 17.3-23.7), and colorectal (SIR, 7.9; 95% CI, 5.2-11.7) cancers, and melanoma (SIR, 6.3; 95% CI, 3.5-10.5) were observed. Of the 341 patients with PHTS with cancer, 51 (15%) had 1 or more cancers diagnosed at age 29 years or younger, and 16 (31.4%) of those developed SMN at final follow-up. Twenty-three patients with PHTS with NDD and cancer were identified, with 5 (22%) having developed SMN at final follow-up. Individuals with PHTS and NDD showed higher lifetime cancer risks compared with individuals with PHTS but without NDD (hazard ratio, 2.7; 95% CI, 1.7-4.2; P < .001). Conclusions and Relevance: This cohort study found consistently elevated lifetime cancer risks in PHTS. Organ-specific surveillance should continue in patients with PHTS. Additional study is required to ascertain elevated cancer risks in patients with PHTS with NDD.

Giant Hemosiderotic Adenodermatofibroma: A Case Report and Review of the Literature.

ABSTRACT: Adenodermatofibromas are an extremely rare subtype of dermatofibroma (DF) characterized by a dermal proliferation of spindle-shaped fibroblasts and histocytes, dilated glandular structures with apocrine secretion, and prominent vascular proliferation, with or without hemosiderotic features. We describe a recent extraordinary case of a hemosiderotic adenodermatofibroma in a 25-year-old female. We review histologic findings and theories behind etiology, as well as review the spectrum of clinical presentations for this lesion. We also discuss imaging findings that may make identification of these entities challenging.

Characterizing dermatologic findings among patients with PTEN hamartoma tumor syndrome: Results of a multicenter cohort study.

BACKGROUND: Dermatologic phenotypes in PTEN hamartoma tumor syndrome (PHTS) are heterogeneous and poorly documented. OBJECTIVE: To characterize dermatologic findings among PHTS and conduct an analysis of genotype-dermatologic phenotype associations. METHODS: Mucocutaneous findings were reviewed in a multicenter cohort study of PHTS. Genotype-dermatologic phenotype associations were tested using multivariable regression. RESULTS: A total of 201 patients were included. Children were significantly less likely than adults to have oral papillomas, vascular malformations, benign follicular neoplasms, and acral keratoses. There were no cases of skin cancer among children. Basal cell carcinoma, cutaneous squamous cell carcinoma, and melanoma developed in 5%, 2%, and 1% of White adults, respectively. After adjusting for age, missense mutations were associated with 60% lower odds of developing cutaneous papillomatous papules (odds ratio: 0.4; 95% confidence interval [0.2, 0.7]), oral papillomas (0.4; 95% confidence interval [0.2, 0.9]), and vascular malformations (0.4; 95% confidence interval [0.2, 0.8]). LIMITATIONS: Partly retrospective data. CONCLUSION: Children are less likely than adults to have certain dermatologic findings, likely due to age-related penetrance. The risk of pediatric melanoma and the lifetime risk of nonmelanoma skin cancer in PHTS may not be elevated. Missense variants may be associated with the development of fewer dermatologic findings but future validation is required.

Congenital syphilis: Missed opportunities and the case for rescreening during pregnancy and at delivery.

Two infants treated for syphilis born to at risk mothers who screened negative at their first prenatal visit but were not rescreened at delivery are described. The first presented with classic, but unrecognized, features of congenital syphilis. In the second case, possible early maternal syphilis was diagnosed soon after delivery using the treponemal first reverse-screening algorithm. Although the child's physical exam was normal and the maternal rapid plasma reagin (RPR) negative, the child was treated for syphilis because maternal confirmatory treponemal tests suggested recent seroconversion. Given the re-emergence of congenital syphilis, our report aims to demonstrate the importance of rescreening women at increased risk and improve awareness of common manifestations of the syphilis disease in the newborn. For women at increased risk, repeat syphilis testing early in the third trimester and again at delivery in communities and populations with a high prevalence of syphilis is recommended.

Cutis marmorata telangiectatica congenita: a focus on its diagnosis, ophthalmic anomalies, and possible etiologic factors.

Purpose: Cutis marmorata telangiectatica congenita (CMTC) is a rare congenital disorder typified by localized or generalized cutaneous vascular anomalies, which dissipate over time. We review the diagnostic approach to CMTC and present a comprehensive examination of its ocular manifestations. Additionally, we offer recommendations for the ophthalmologic workup for patients with CMTC. Finally, we examine the possible causes of CMTC and summarize the current efforts to establish an etiologic mechanism for this disease.Methods: Thirty-three published cases of CMTC with ocular anomalies are examined in detail.Results: CMTC is diagnosed based on a specific set of congenital cutaneous symptoms, principally congenital reticular erythema that is unresponsive to local warming and absence of venectasia within the skin lesions. Ocular findings are not currently employed in this diagnostic process, likely due to an incomplete understanding into their presentation, frequency, and natural history. We show that the majority of ophthalmic manifestations are congenital, with glaucoma and posterior segment anomalies, consisting of retinal perfusion defects and vascular abnormalities, as the most frequently reported findings. Typical ophthalmic medical and surgical interventions appear to be effective for management of these CMTC-related pathology. Unfortunately, the etiology and pathophysiology of CMTC remains unknown, which obfuscates efforts to identify, examine, and initiate treatment in patients.Conclusions: While the ophthalmic community has traditionally viewed glaucoma as the classic ocular anomaly of CMTC, this dataset advocates for the prompt investigation of posterior segment abnormalities as well. However, our understanding of CMTC's ocular anomalies is complicated by a lack of reporting and/or incomplete (or nonexistent) ophthalmic examinations, and we strongly encourage comprehensive ophthalmic examinations for all CMTC patients at the time of diagnosis, followed by appropriate screening and surveillance throughout life. We believe these recommendations will spur additional data and disease insights that may be useful for future refinements to CMTC diagnostic algorithms.

Atenolol Versus Propranolol for Treatment of Infantile Hemangiomas During the Proliferative Phase: A Retrospective Noninferiority Study.

BACKGROUND/OBJECTIVES: The nonselective beta-blocker propranolol is the current criterion standard for treatment of infantile hemangiomas (IHs) and the first therapy that the U.S. Food and Drug Administration has approved for the condition, but concern about adverse effects, such as bronchospasm, hypoglycemia, and sleep disturbances, has sparked interest in the use of alternative agents such as the selective ß1 antagonist atenolol. Our aim was to compare the efficacy and adverse effect profiles of atenolol with those of propranolol in the treatment of IHs in a retrospective noninferiority trial. METHODS: Twenty-seven children with IHs treated with atenolol according to the Cleveland Clinic foundation's standardized clinical assessment and management plan (SCAMP) met inclusion criteria and were compared with a matched group of 53 children with IHs treated with propranolol. Three reviewers assessed response to therapy using a modified version of the previously validated Hemangioma Activity Score (HAS). RESULTS: The mean change in HAS was -2.94 ± 1.20 for patients treated with atenolol and -2.96 ± 1.42 for those treated with propranolol. There was no statistically significant difference in pre- and posttreatment modified HAS scores between the two groups (p = 0.60). There was no significant difference in the overall rate of adverse effects (p = 0.10), although 11% of patients treated with propranolol experienced reactive airway symptoms, whereas this was not seen in any of the patients treated with atenolol. CONCLUSION: Our study supports previous findings that atenolol is at least as effective as propranolol for treatment of IHs and poses less risk of bronchospasm. Our SCAMP proposes guidelines for dosing and monitoring parameters.

Brimonidine Toxicity Secondary to Topical Use for an Ulcerated Hemangioma.

Combigan (Allergan, Irvine, CA) is an ophthalmic solution that combines 0.2% brimonidine, a selective α-2 adrenergic agonist, with 0.5% timolol, a nonselective ß-adrenergic antagonist. It is approved for the reduction of intraocular pressure in patients with glaucoma or ocular hypertension. There have been recent reports of successful treatment of superficial infantile hemangiomas (IHs) using Combigan topically. We report the case of a 2-month-old girl who developed life-threatening brimonidine toxicity requiring intubation and mechanical ventilation secondary to central nervous system depression and apnea after topical application to an ulcerated IH.

Beta Blockade as Treatment for Intracranial Infantile Hemangioma: Case Report and Literature Review.

BACKGROUND: Intracranial infantile hemangiomas are extremely rare, with only 36 patients reported in literature. Treatment for intracranial infantile hemangiomas has been mostly limited to surgery, steroids, and interferon therapy. Propranolol, which is often used to treat cutaneous infantile hemangiomas, is not currently standard treatment for intracranial infantile hemangiomas. PATIENT DESCRIPTION: We present a one-month old boy with an intracranial infantile hemangioma treated with propranolol. RESULTS: This boy was being treated with oral propranolol for a supraclavicular infantile hemangioma. Subsequent brain magnetic resonance imaging (MRI) scan showed evidence of an associated intracranial infantile hemangioma in the right cerebellopontine angle. Repeat brain MRI scan after two months of propranolol treatment demonstrated a significant reduction in the size of the intracranial infantile hemangioma. CONCLUSIONS: This is the first report of successful therapy of an intracranial infantile hemangioma with propranolol.

Propranolol for Treatment of Genital Infantile Hemangioma.

PURPOSE: Genital infantile hemangiomas are vascular anomalies that often require complex management and interdisciplinary care. Propranolol was first used to treat patients with infantile hemangiomas in 2008 and has since gained acceptance as first-line therapy. MATERIALS AND METHODS: We review the presentation, course, management and outcomes of all cases of genital infantile hemangiomas managed by propranolol administration at a single institution from April 2010 to July 2014. RESULTS: During the study period 9 patients with genital infantile hemangiomas were referred to our hemangioma treatment clinic. Propranolol was initially administered under careful outpatient monitoring at a dose of 1 mg/kg daily in 8 patients. One patient, a 700 gm premature infant, was started on therapy in the inpatient setting at 0.5 mg/kg daily, given the history of prematurity. All patients underwent successful increase of dose to at least 2 mg/kg for the observation phase after tolerating the starting doses. One patient discontinued propranolol prematurely per parental request due to concern regarding peripheral vasoconstriction. Otherwise, no patient demonstrated significant hypotension, symptomatic bradycardia, hypoglycemia or other major side effect requiring treatment discontinuation. All patients who continued the treatment protocol had excellent response to therapy. CONCLUSIONS: Propranolol therapy for genital infantile hemangiomas was successfully initiated and the dosage increased in 9 young children without significant side effects and with marked improvement in all patients who continued on treatment. Propranolol is the only Food and Drug Administration approved therapy for treatment of patients with this vascular anomaly and should be considered first-line therapy for genital infantile hemangiomas.

The Financial and Emotional Impact of Atopic Dermatitis on Children and Their Families.

OBJECTIVE: To examine the personal financial impact of atopic dermatitis (AD) and attempt to correlate cost of AD with emotional impact. STUDY DESIGN: Between March 2011 and December 2013, 82 caretakers of children 6 months to 12 years of age with moderate-to-severe AD were recruited at the time of dermatology clinic visits in Cleveland, Ohio, to complete surveys. The response rate was >95%. Participants were asked questions about direct expenses (medical visits, medications, and other products) and indirect expenses (time missed from work, childcare costs) related to AD in the past 4 weeks. Emotional impact was measured by the Childhood Atopic Dermatitis Impact Scale. RESULTS: The mean monthly personal cost of AD in the month before the office visit was $274 (median $114; IQR $29, $276), with $75 from direct costs (median $45; IQR $20, $110) and $199 from indirect costs (median $0; IQR $0, $208). An average of 34.8% of available monthly money was spent on AD care in the month before the office visit. For patients with Medicaid, there was a significant correlation between monthly adjusted personal cost and Childhood Atopic Dermatitis Impact Scale score (r = 0.548; P < .001); however, this correlation did not exist for patients who had commercial insurance (r = 0.269; P = .166). CONCLUSIONS: Our results illustrate the high emotional and financial burden of childhood AD and provide insight into spending patterns. In addition, our study correlate costs with emotional burden of AD for lower-income patients.

Dermatology for the pediatrician: Advances in diagnosis and treatment of common and not-so-common skin conditions.

Advances have been made in understanding and treating both common and rare dermatologic conditions. Atopic dermatitis benefits from bathing and ceramide moisturizers. Common allergic contact dermatitis may have specific presentations. Tinea capitis is effectively treated with terbinafine. Infantile hemangiomas should be treated early in the disease course and respond well to propranolol; any white sign of ulceration should be noted. Localized alopecia areata responds well to topical clobetasol, avoiding the need for intralesional injections. Topical rapamycin can be used to treat tuberous sclerosis. Further understanding of genetics will help guide pediatricians to the proper diagnosis and treatment of skin conditions.

Colocalization of vitiligo and alopecia areata presenting as poliosis.

Vitiligo and alopecia areata are two cutaneous diseases believed to be primarily autoimmune in pathogenesis. While the coexistence of the two conditions in the same patient has been well-described, reports of the two disease processes occurring in the same location are rare. We report the case of a 10-year-old male with an unremarkable past medical history who presented with a single localized area of poliosis with depigmented underlying skin on the frontal scalp. The hair in the affected area was relatively decreased in density. A punch biopsy of the depigmented patch demonstrated features consistent with both vitiligo and alopecia areata. The decreased number of large hair follicles and a focal peribulbar lymphocytic infiltrate around an anagen follicle were suggestive of alopecia areata. A panel of melanocyte-specific stains revealed absent melanocytes in the epidermis, consistent with vitiligo. Loss of microphthalmia-associated transcription factor-positive root sheath cells was seen, suggestive of loss of melanocyte stem cells. The combination of clinical and histopathologic findings supports the theory of a common pathogenesis of alopecia areata and vitiligo.

Periocular granuloma annulare: a case report and review of literature.

Granuloma annulare (GA) is a granulomatous dermatosis that rarely presents on the face and is extremely uncommon in the periocular region. We report our experience with the presentation and management of GA lesions on the eyelids of a 17-year-old girl. We performed a review of published literature and identified 13 cases of pediatric periocular GA. One additional case was identified upon review of all pediatric GA cases at the Cleveland Clinic Foundation. Review of these cases suggests that periocular GA is a benign condition that spontaneously regresses within a few months. GA nodules have a predilection for the upper eyelids. A greater incidence is noted in African American children. Awareness of the self-resolving nature of this condition can prevent unnecessary surgical excisions in affected children.

Herlitz junctional epidermolysis bullosa with a novel mutation in LAMB3.

Herlitz junctional epidermolysis bullosa (H-JEB) is a rare, heritable mechanobullous disease that affects infants at birth and causes early death. This disease is primarily caused by compound heterozygous or homozygous mutations in one of three genes affecting the function of one of the three chains of the laminin-332 (formerly laminin-5) protein. Here we report a case of H-JEB with a novel heterozygous mutation in LAMB3,c.1597G>A (p.Ala533Thr). These findings attest to the molecular heterogeneity of JEB and emphasize the importance of genetic analysis to help make an accurate diagnosis, predict clinical prognosis, and identify phenotypic-genotypic relationships that may aid in prenatal diagnosis and genetic counseling for the future.

Aquagenic wrinkling of the palms and the potential role for genetic testing.

Aquagenic wrinkling of the palms (AWP) is a condition characterized by excessive wrinkling, palmar edema, and whitish papules accompanied by pain, pruritus, or discomfort after brief immersion of the hands in water. It is well documented to be associated with cystic fibrosis (CF), with several theories regarding the pathogenesis having been proposed. We report a case of two sisters with AWP in whom CF has not been diagnosed and review the literature on AWP and its association with CF and CF carrier status. Because diagnosis of mild forms CF or knowledge of an underlying CF genetic mutation is frequently unknown, identification of AWP may represent the only sign of such mutations. The dermatologist plays an integral role in early detection of AWP, and the importance of genetic testing in such patients cannot be overlooked. We recommend various measures to apply in clinical practice to ensure diagnosis and decrease morbidity and mortality in patients.
