- Abstract
Summary: Congenital adrenal hyperplasia (CAH) is one of the most common inherited rare endocrine disorders. This case report presents two female siblings with delayed diagnosis of non-classical CAH 3β-hydroxysteroid dehydrogenase type 2 (3βHSD2D/HSD3B2) despite early hospital admission and apparent CAH manifestations such as infections, hirsutism, menstrual disturbances, and PCOS phenotype. Initially, sister 1 was misdiagnosed with PCOS and then 11-hydroxylase deficiency (CYP11B1), based on ultrasound, biochemical findings, and negative genetic testing for 21-hydroxylase deficiency (CYP21A2). Additional diagnostic workup was performed when sister 2also presented with symptoms of androgen excess. Genetic testing for CAH/steroid disorders finally revealed that both siblings were compound heterozygous for two variants in the HSD3B2 gene: a frameshift variant, c.558dup, p.(Thr187Hisfs*17) and a novel missense variant, c.65T>C, p.(Leu22Ser). A Synacthen test showed an insufficient cortisol increase. In vitro studies of the variants in a cell model revealed loss of function for the p.(Thr187Hisfs*17) and partial activity for p.(Leu22Ser) confirming non-classic CAH. Overlapping symptomatology and lack of specialized knowledge on steroid biosynthesis and associated rarest forms of CAH may explain the delayed diagnosis. However, with newer diagnostic methods comprising a less biased approach, very rare forms of non-classical CAH may no longer be overlooked in the future., Learning Points: Non-classic 3βHSD2 is likely underdiagnosed. Late diagnosis of mild non-classic 3βHSD2 does occur and one should be aware of this diagnosis. Early diagnosis of NCCAH may prevent many consequences such as severe hirsutism, prolonged menstrual irregularities, infertility, or even adrenal crisis with severe infections. Comprehensive steroid profiling and genetic testing should be used earlier, especially when in doubt about a diagnosis.

- Abstract
Palmoplantar keratoderma (PPK) is a heterogeneous group of rare skin diseases characterized by hyperkeratosis on the palms or soles. The subtype isolated punctate PPK is caused by heterozygous variants in AAGAB. We investigated if the variant AAGAB c.370C>T, p.Arg124Ter in patients with punctate PPK in the Region of Southern Denmark represented a founder variant and estimated the age to the most recent common ancestor. We performed haplotype analysis on samples from 20 patients diagnosed with punctate PPK and the AAGAB c.370C>T, p.Arg124Ter variant. Using the Gamma Method, we calculated the years to the most recent common ancestor. We also explored the presence of the variant in other populations through literature and databases (HGMD, ClinVar, and gnomAD). Our analysis revealed a shared haplotype of 3.0 Mb, suggesting shared ancestry. The ancestral haplogroup was estimated to an age of 12.1 generations (CI: 4.9-20.3) equivalent to approximately 339 years (CI: 137-568). This study confirms that the frequently observed variant AAGAB c.370C>T, p.Arg124Ter in punctate PPK among patients in the Region of Southern Denmark is caused by a founder variant. We recommend testing for the variant as initial screening in our region and potentially for all Danish patients presenting with punctate PPK., (© 2024 The Authors.

- Abstract
Background: Genomic profiling is increasingly used both in therapeutic decision-making and as inclusion criteria for trials testing targeted therapies. However, the mutational landscape may vary across different areas of a tumor and intratumor heterogeneity will challenge treatments or clinical decisions based on single tumor biopsies. The purpose of this study was to assess the clinical relevance of genetic intratumor heterogeneity in head and neck squamous cell carcinomas (HNSCC) using the ESMO Scale for Clinical Actionability of Molecular Targets (ESCAT)., Materials and Methods: This prospective study included 33 whole tumor specimens from 28 patients with primary or recurrent HNSCC referred for surgery. Three tumor blocks were selected from central, semi-peripheral, and peripheral positions, mimicking biopsies in three different locations. Genetic analysis of somatic copy number alterations (SCNAs) was performed on the three biopsies using Oncoscan, focusing on 45 preselected HNSCC genes of interest. Clinical relevance was assessed using the ESCAT score to investigate whether and how treatment decisions would change based on the three biopsies from the same tumor., Results: The SCNAs identified among 45 preselected genes within the three tumor biopsies derived from the same tumor revealed distinct variations. The detected discrepancies could potentially influence treatment approaches or clinical decisions in 36% of the patients if only one tumor biopsy was used. Recurrent tumors exhibited significantly higher variation in SCNAs than primary tumors ( p = .024). No significant correlation between tumor size and heterogeneity ( p = .7) was observed., Conclusion: In 36% of patients diagnosed with HNSCC, clinically significant intratumor heterogeneity was observed which may have implications for patient management. This finding substantiates the need for future studies that specifically investigate the clinical implications associated with intratumor heterogeneity.

- Abstract
Background: An association between punctate palmoplantar keratoderma type 1 (PPPK1) and malignancy has been proposed for decades. Some authors suggest that individuals with PPPK1 should undergo screening for various types of malignancies while others caution that an association is not well-established. In this systematic review, we summarized and evaluated the current evidence for a possible association between PPPK1 and malignancy., Methods: The review was conducted along PRISMA guidelines. The search used Embase, MEDLINE, Scopus, and the Human Gene Mutation Database up to March 2022. All studies reporting on individuals with the diagnosis of PPPK1 with or without history of malignancy were included. Two authors screened for eligible studies, extracted predefined data, and performed a quality assessment., Results: Of 773 studies identified, 45 were included. Most studies were reports on single families (24 of 45 studies) or multiple families (10 of 45 studies). The number of index cases with PPPK1 across all included studies was 280, and when family members reported with PPPK1 were added, a total of 817 individuals were identified. Overall, 23 studies reported on individuals with PPPK1 with a history of malignancy, whereas 22 studies reported on individuals with PPPK1 without a history of malignancy. Although the extracted data were not considered to be of sufficient quality to synthesize and answer our research question, the review did not confirm an association between PPPK1 and malignancy., Conclusion: This review shows that there is a lack of well-designed studies on this topic to conclude whether individuals with PPPK1 have an increased risk of malignancy. Based on the present literature, however, we could not confirm an association between PPPK1 and malignancy and find it highly questionable if patients with PPPK1 should be offered surveillance for malignancies., (© 2023.

- Abstract
Pityriasis rubra pilaris (PRP) is a rare dermatosis characterised by hyperkeratotic follicular papules, orange-red scaly plaques and palmoplantar keratoderma. The aetiology of the disease is in most cases unclear and treatment can be challenging. Familial cases of PRP may result from pathogenic variants in the caspase recruitment domain family member 14 (CARD14). We present a case of lifelong PRP in a 70-year-old woman, where genetic testing revealed a heterozygote missense variant c.412G>A, p.(Glu138Lys) in CARD14. Therapy with ustekinumab was initiated with remarkable effect, which improved the patient's quality of life significantly., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2020.

- Abstract
Purpose: The purpose of this study was to assess the use of 18F-FDG PET/CT scans for detecting distant metastases in patients with recurrent head and neck squamous cell carcinoma (HNSCC) and investigate the treatment and survival of patients with recurrence., Methods: In this retrospective study, consecutive head and neck cancer patients referred for FDG PET/CT scan between 2012 and 2014 were included. Patient records were reviewed and only patients with recurrence of HNSCC were enrolled for further analysis. Information on distant metastases, surgery and survival was collected. A Kaplan-Meier analysis was used to report survival., Results: Overall 275 PET/CT scans were performed due to suspected recurrence, and in 166 scans (144 patients), recurrence of HNSCC was confirmed, making them eligible for further analysis. Distant metastases were revealed in 29.8% of the scans (n = 51) and the proportion of revealed metastases remained constant at approximately 30% each year. Although the number of performed scans increased twofold each year, there was no statistically significant change in the proportion of scans with distant metastasis (p = 0.55). The distant metastases were most often seen in the lungs (n = 44) and bone (n = 15). A few patients had widespread dissemination to other areas. Salvage surgery was performed following 81 of the 166 PET/CT scans. Seven of the patients who underwent salvage surgery had M-site oligo-metastases. Patients who underwent salvage surgery had a median survival of 22 months whereas patients not treated with salvage surgery had a median survival of 6 months. After 5 years, 21% of the patients selected for salvage surgery were alive., Conclusions: Distant metastases occur frequently in patients with recurrent HNSCC disease and the proportion of revealed distant metastases remained the same (30%). Imaging with FDG PET/CT can be recommended in patients with recurrent HNSCC prior to putative salvage surgery.

- Abstract
Objectives: The aims of this study were to report the risk of thyroid malignancy in cases of either benign fine-needle aspiration (FNA) or without FNA performed, and to investigate possible predictive factors for thyroid malignancy in a population with recent moderately low iodine intake., Methods: All patients referred for thyroid surgery in a tertiary cancer centre between 2000 and 2016 were included ( n = 3,703). After excluding cases indicating malignant histology, we included group 1: patients with benign FNA ( n = 764), and group 2: patients without FNA ( n = 740), leaving 1,504 eligible for further investigation. Information on age, gender, tracheal compression or dislocation, thyroid specimen weight, scintigraphy, ultrasound, medically treated thyrotoxicosis, serum stimulating thyroid hormone, indication for surgery, TNM classification, stage, and outcome were retrieved., Results: The malignancy risk was 7.6% (58/764) in group 1 and 6.8% (50/740) in group 2. Patients with T2-4 tumours constituted 2.2% (33/1,504). In the combined groups, ultrasound verified that solitary solid tumour was predictive for malignancy (p = 0.01 by χ
2 , and OR = 1.69, p = 0.02 in multiple logistic regression). For group 1 patients, thyrotoxicosis (which in this case was medically treated) was a significant predictive factor for malignancy ( p = 0.04)., Conclusions: The risk of malignancy of 7.6% and 6.8% was high, considering that patients with malignant FNA, suspicious FNA, or clinical findings indicating malignancy were excluded, and 2.2% of these malignancies were stages T2-4. In cases with solitary solid tumour on ultrasound, the risk of malignancy should not be ignored, even with benign FNA., Competing Interests: The authors have no conflicts of interest to declare., (Copyright © 2019 by S.

- Abstract
The aim of this study was to report incidence and patient characteristics of olfactory neuroblastoma (ONB) at a tertiary cancer institution during a 16-year period. A retrospective review was conducted on patients with ONB treated at Rigshospitalet, Copenhagen from 2000 to 2016 covering Eastern Denmark. Patient demographics, symptoms, stage, pathology-reports, treatment, and outcome were extracted from the patient records and the Danish pathology register. The tumours were graded both histologically and clinically using Hyam's and Kadish classifications, respectively. We identified a total of 14 patients (ten males, four females, median age 57 years, range 17-81 years). Four patients were in Kadish stage A, one stage B, and seven stage C. According to Hyam's classification, two tumours were grade I, nine grade II, and three grade III. All patients were treated with surgery, eight in combination with radiotherapy, where one received proton therapy, and one a combination with chemotherapy. At a median follow-up time of 58 months, the 5-year overall survival was 90% (95% CI 61; 99). ONB is a rare disease; complete radical surgery alone or combined with radiotherapy offered good oncologic control and outcome. Long-term follow-up of ONB should be mandatory., (© 2018 APMIS.
