The "bumpy" adolescent nose: Acne associated angiofibroma-like nasal papules.

BACKGROUND/OBJECTIVE: Papular scars are a recently described clinical phenotype of acne scarring characterized by papules occurring on the nose and chin. We have observed a similar presentation of nasal papules among patients seen in our clinic for acne and sought to further characterize the clinical and histopathological characteristics of this entity. METHODS: In this single-site case series, a retrospective review of electronic medical records of patients with nasal papules in association with acne vulgaris between April 2018 and April 2019 was performed. Clinical and histopathologic findings were recorded. RESULTS: We identified 20 patients who presented with a similar clinical phenotype of predominantly skin-colored, dome-shaped papules concentrated on the nose and chin in association with a history of more classic facial acne vulgaris. Papular lesions were seen predominately in adolescent Hispanic males. Concomitant acne on other areas of the face was identified in 18 patients at presentation while two patients had a history of adolescent acne. Biopsies were performed for five patients. Histopathologic examination demonstrated features of fibrosis and dilated thin-walled blood vessels, typical of angiofibromas. CONCLUSION: We present a series of adolescent patients with large, flesh-colored to erythematous papules seen predominantly on the nose. These lesions are histologically indistinguishable from angiofibromas and may represent an under-recognized yet disfiguring sequela of acne that may disproportionately affect adolescents with skin of color.

Dabrafenib-induced neutrophilic panniculitis in a child undergoing dual BRAF-MEK inhibitor therapy for glioblastoma multiforme.

BRAF inhibitor-induced neutrophilic panniculitis is a rare event that is well-characterized in adults undergoing therapy for metastatic melanoma. To date, there are very few reports of this event in children undergoing BRAF inhibitor therapy for low-grade gliomas, all of which were seen with vemurafenib. We report a case of dabrafenib-induced neutrophilic panniculitis in a 9-year-old girl that manifested within several weeks of initiating dual BRAF-MEK inhibitor therapy for glioblastoma multiforme. This case highlights neutrophilic panniculitis as a side effect of dabrafenib in children and serves as a reminder to consider cutaneous side effects of BRAF inhibitors as they are increasingly used to treat children with primary brain tumors.

An Overview of Penile and Scrotal Dermatoses.

There are a number of dermatoses that manifest in the genital region. Urologists are often the first point of contact for patients with such disorders. These can be isolated genital conditions or manifestations of a more widespread cutaneous disease. Though similar appearing, there are often key clinical findings that aid in in diagnosis. In general, genital dermatoses can be classified as physiologic variants, inflammatory, neoplastic, or infectious in etiology. This article provides a broad overview for urologists in addressing both common and rarer penile and scrotal dermatoses. Emphasis is placed on characteristic clinical findings to aid in diagnosis. Recommendations for diagnostic evaluation, treatment, and appropriate follow-up are discussed.

Exanthematous Eruptions in Children.

Childhood exanthems are commonly encountered by pediatricians in the hospital and the office. In the last several decades, we have seen a shift in the epidemiology of many of these diseases. After being deemed eliminated at the turn of 21st century, measles has experienced a resurgence secondary to falling vaccination rates, raising public health concerns. A new variant of hand, foot, and mouth disease caused by coxsackievirus A6 has been associated with more widespread and atypical disease, which can present diagnostic challenges to clinicians. Parvovirus B19, which is traditionally associated with fifth disease, is also the leading cause of papular purpuric gloves and socks syndrome, a rare condition with which providers may be unfamiliar. Since the introduction of routine vaccination, there has been a shift in the epidemiology and clinical presentation of primary varicella and herpes zoster. Finally, the recently described phenomenon of Mycoplasma pneumoniae-induced rash and mucositis will be discussed. [Pediatr Ann. 2020;49(3):e116-e123.].

Breast Cancer Screening in High-Risk Men: A 12-year Longitudinal Observational Study of Male Breast Imaging Utilization and Outcomes.

Background Male breast cancer incidence is rising. There may be a potential role in selective screening in men at elevated risk for breast cancer, but the effectiveness of such screening remains unexplored. Purpose To evaluate patterns of male breast imaging utilization, to determine high-risk screening outcomes, and to delineate risk factors associated with cancer diagnosis. Materials and Methods This retrospective study reviewed consecutive male breast imaging examinations over a 12-year period (between 2005-2017). Examination indications, biopsy recommendations, and pathologic results were correlated with patient characteristics. Fisher exact test, Mann-Whitney test, Spearman correlation, and logistic regression were used for statistical analysis. Results A total of 1869 men (median age, 55 years; range, 18-96 years) underwent 2052 examinations yielding 2304 breast lesions and resulting in 149 (6.5%) biopsies in 133 men; 41 (27.5%) were malignant and 108 (72.5%) were benign. There were 1781 (86.8%) diagnostic and 271 (13.2%) screening examinations. All men undergoing screening had personal or family history of breast cancer and/or genetic mutations. There was a significant increase in the number of examinations in men relative to the number of examinations in women over time (Spearman correlation, r = 0.85; P < .001). Five node-negative cancers resulted from screening mammography, yielding a cancer detection rate of 18 per 1000 examinations (95% confidence interval [CI]: 7, 41), with cancers diagnosed on average after 4 person-years of screening (range, 1-10 person-years). Mammographic screening sensitivity, specificity, and positive predictive value of biopsy were 100% (95% CI: 50%, 100%), 95.0% (95% CI: 93.1%, 98%), and 50% (95% CI: 22.2%, 77.8%). Older age (P < .001), Ashkenazi descent (P < .001), genetic mutations (P = .006), personal history (P < .001), and first-degree family history (P = .03) were associated with breast cancer. Non-first-degree family history was not associated with cancer (P = .09). Conclusion There is potential benefit in screening men at high risk for developing breast cancer. Such screening may have increased over time. © RSNA, 2019.
