Abstract
BRCA1-associated protein-1 (BAP1) is a recognised tumour suppressor gene. Germline BAP1 pathogenic/likely pathogenic variants are associated with predisposition to multiple tumours, including uveal melanoma, malignant pleural and peritoneal mesothelioma, renal cell carcinoma and specific non-malignant neoplasms of the skin, as part of the autosomal dominant BAP1-tumour predisposition syndrome. The overall lifetime risk for BAP1 carriers to develop at least one BAP1-associated tumour is up to 85%, although due to ascertainment bias, current estimates of risk are likely to be overestimated. As for many rare cancer predisposition syndromes, there is limited scientific evidence to support the utility of surveillance and, therefore, management recommendations for BAP1 carriers are based on expert opinion. To date, European recommendations for BAP1 carriers have not been published but are necessary due to the emerging phenotype of this recently described syndrome and increased identification of BAP1 carriers via large gene panels or tumour sequencing. To address this, the Clinical Guideline Working Group of the CanGene-CanVar project in the United Kingdom invited European collaborators to collaborate to develop guidelines to harmonize surveillance programmes within Europe. Recommendations with respect to BAP1 testing and surveillance were achieved following literature review and Delphi survey completed by a core group and an extended expert group of 34 European specialists including Geneticists, Ophthalmologists, Oncologists, Dermatologists and Pathologists. It is recognised that these largely evidence-based but pragmatic recommendations will evolve over time as further data from research collaborations informs the phenotypic spectrum and surveillance outcomes.

Abstract
BRCA1-associated protein 1 (BAP1)-inactivated melanomas can occur sporadically or in germline contexts, particularly in recently recognized BAP1-tumor predisposition syndrome. Diagnosis represents a clinical and histopathological challenge, requiring comprehensive analysis of morphology and sometimes molecular analysis in addition to immunohistochemistry. We report a BAP1-inactivated cutaneous melanoma initially diagnosed as an atypical Spitz tumor on the auricle in a patient with BAP1-tumor predisposition syndrome. Immunohistochemistry, fluorescence in situ hybridization, and comparative genomic hybridization allowed diagnosis. Cutaneous BAP1-inactivated melanocytic tumors, previously classified as atypical Spitz Nevi, may have a dermal mitotic activity that can resemble melanoma and on the other hand, atypical Spitz tumors are sometimes difficult to differentiate from BAP1-inactivated melanoma. Specific criteria, requiring molecular diagnosis have been proposed in order to support melanoma diagnosis.

Abstract
Pigmented epithelioid melanocytoma is a rare cutaneous melanocytic proliferation considered high-grade melanocytoma in the 2018 WHO Classification of Skin Tumors. Little has been reported about the associated genetic drivers in addition to BRAF and MAP2K1 mutations or PRKCA gene fusions. Here, we present a series of 21 cases of PRKAR1A -inactivated melanocytic tumors in which we could assess the associated genetic background. We identified 9 different driver genes related to the common, Spitz, blue nevi, and PRKC -fused groups. Nine cases were associated with a canonical BRAF p.V600E mutation, a hallmark of the common nevus group. They occurred mainly in young adults. All were combined (biphenotypic) cases with a variable proportion of compound nevus. The pigmented epithelioid melanocytoma component was made of thin fascicules or isolated epithelioid cells covered by a dense hyperpigmented melanophage background and was predominantly located in the upper dermis. One such case was malignant. Six cases were associated with Spitz-related genetic anomalies ranging from HRAS or MAP2K1 mutations to gene fusions involving MAP3K8 , MAP3K3 , and RET . They occurred mainly in children and young adults. Morphologically, they showed large confluent junctional nests in a hyperplastic epidermis and a fascicular dermal component of spindled and epithelioid melanocytes with a frequent wedged silhouette. Intravascular invasion was observed in 4/6 cases. Five cases were associated with canonical mutations of the blue nevus group with 4 CYSLTR2 p.L129Q and 1 GNAQ p.Q209L mutations. They were removed mainly in adults and showed a frequent junctional component with epidermal hyperplasia. The dermal component showed dense fascicules of spindled and epithelioid melanocytes predominating over melanophages. One case occurred in a PRKCA -fused tumor in an adolescent with classic morphologic features. These results could potentially shift the concept of PRKAR1A -inactivated melanocytoma, changing from a rather unified model to a more complex one, including genetic subgroup variations with clinical and morphologic specificities. The genetic background of PRKAR1A -inactivated melanocytic tumors should be systematically explored to better understand the extent and clinical behavior of these complex lesions.

Abstract
OBJECTIVE BRCA1-associated protein 1 (BAP1) tumor predisposition syndrome (BAP1-TPDS) is associated with an increased risk for aggressive cancers. BAP1-inactivated melanocytic tumors (BIMTs) are observed in 75% of BAP1-TPDS, often presenting as early as the second decade of life. These lesions may serve as a predictive marker to identify patients who carry germline BAP1 mutations and thus are at higher risk of developing associated cancers. Early diagnosis for these malignancies is crucial for curative treatment. METHODS We report a patient who presented with an incidental scalp papule for which biopsy was consistent with a BIMT. A review of literature was conducted by accessing the PubMed database to delineate present knowledge of BIMTs, assess recommendations for screening of germline BAP1 mutations, and evaluate cancer surveillance strategies for BAP1-TPDS associated cancers. RESULTS Consensus in literature indicates that genetic evaluation should be encouraged in patients presenting with multiple BIMTs or a new BIMT with significant family history of BAP1-TPDS related cancers. If positive for a germline BAP1 mutation, cancer surveillance should be recommended for early diagnosis and timely intervention. CONCLUSIONS Further workup should be encouraged in patients who meet the proposed screening criteria for germline BAP1 mutations. Patients could benefit from cancer surveillance for earlier diagnosis, management, and improved outcomes.

Abstract
BRCA1-associated Protein 1 (BAP1)-inactivated melanocytic nevi/tumors (BIMT) have distinct morphologic features. A typical case exhibits a biphasic population of cytologically bland conventional melanocytes and a second proliferation of larger epithelioid melanocytes with abundant eosinophilic cytoplasm. The vast majority of cases harbor BRAF V600E in both components with bi-allelic inactivation of BAP1 in the epithelioid component by various molecular mechanisms resulting in loss of nuclear protein expression, which can be demonstrated by immunohistochemistry. We present a case of BIMT with histopathologic features highly suggestive of this entity but unexpected retention of nuclear expression of the BAP1 protein. Subsequent molecular tests showed heterozygous loss of the BAP1 locus on the short arm of chromosome 3 (3p21.1) by chromosomal microarray analysis (CMA) and a suspected c.505C>T p.H169Y pathogenic variant identified by DNA sequencing that was subsequently confirmed by primer-specific SNaPshot mini-sequencing. In light of the heterozygous deletion of BAP1, this variant in the remaining allele encodes a catalytically inactive BAP1 mutant protein as shown in functional studies. The presence of a nonfunctional allele within the nucleus combined with a heterozygous deletion of BAP1 explains the clear and characteristic BIMT morphology observed by histopathology. This case underlines the potential importance of molecular diagnostics when protein expression studies do not correlate with morphology.

Abstract
Although discussed using variable terminology, cutaneous BRCA1-associated protein (BAP1)-inactivated melanocytic tumor (BIMT) has been considered a discrete diagnostic entity since 2011. Here, we review the initial genomic studies that identified these distinct melanocytic tumors and the clinical and histopathological features that define these tumors. These epithelioid, predominantly dermal, and melanocytic tumors present as erythematous nodules and histopathologically have features that may overlap with Spitz nevi and nevoid melanoma. There is no sex predilection, and cutaneous BIMTs can appear at any age; however, in most familial (germline mutant) cases patients have multiple cutaneous tumors with a first diagnosis in the second or third decade of life; ocular melanoma and other tumors are increasingly identified in these kindreds with germline BAP1 mutation. These tumors have been described with a myriad of terms including: Wiesner nevus, nevoid melanoma-like melanocytic proliferation (NEMMP), BAP1 mutant Spitz nevus, BAP1 mutant nevoid melanoma, cutaneous BAPoma, and most recently cutaneous BIMT.

Abstract
Germline pathogenic variants in the BRCA1-associated protein-1 (BAP1) gene cause the BAP1-tumor predisposition syndrome (BAP1-TPDS, OMIM 614327). BAP1-TPDS is associated with an increased risk of developing uveal melanoma (UM), cutaneous melanoma (CM), malignant mesothelioma (MMe), renal cell carcinoma (RCC), meningioma, cholangiocarcinoma, multiple non-melanoma skin cancers, and BAP1-inactivated nevi. Because of this increased risk, it is important to identify patients with BAP1-TPDS. The associated tumors are treated by different medical disciplines, emphasizing the need for generally applicable guidelines for initiating genetic analysis. In this study, we describe the path to identification of BAP1-TPDS in 21 probands found in the Netherlands and the family history at the time of presentation. We report two cases of de novo BAP1 germline mutations (2/21, 9.5%). Findings of this study combined with previously published literature, led to a proposal of guidelines for genetic referral. We recommend genetic analysis in patients with ≥2 BAP1-TPDS-associated tumors in their medical history and/or family history. We also propose to test germline BAP1 in patients diagnosed with UM <40 years, CM <18 years, MMe <50 years, or RCC <46 years. Furthermore, other candidate susceptibility genes for tumor types associated with BAP1-TPDS are discussed, which can be included in gene panels when testing patients.

Abstract
Malignant mesothelioma is a rare tumour, usually the result of asbestos exposure. Several cases of familial aggregation have been reported and recently shown to be associated with constitutional mutations of the BAP1 gene. BAP1 is a deubiquitinating enzyme implicated in several different cellular mechanisms such as the repair or differentiation of DNA. About a half of malignant mesotheliomas present a somatic, bi-allelic inactivation of BAP1, demonstrated by nuclear extinction on histochemistry. Constitutional alterations of BAP1 are extremely rare. Present in the heterozygous state they are transmitted as an autosomal dominant. They are associated with a risk of developing other tumours such as uveal and cutaneous melanomas, benign melanocytic tumours (melanocytic BAP1-mutated atypical intradermal tumour or MBAITS) and clear cell renal carcinomas. The causal link between mesothelioma and germinal mutations of BAP1 has still not been clearly identified. At present there is, in France, no consensus on recommendations for the management of patients with these mutations. This article is a synthesis of the literature on the functions of the BAP1 gene, the tumour risks related to its alteration and the follow up of patients bearing a constitutional mutation.

Abstract
Background The BRCA1-associated protein-1 (BAP1) tumor predisposition syndrome (BAP1-TPDS) is a hereditary tumor syndrome caused by germline pathogenic variants in BAP1 encoding a tumor suppressor associated with uveal melanoma, mesothelioma, cutaneous melanoma, renal cell carcinoma, and cutaneous BAP1-inactivated melanocytic tumors. However, the full spectrum of tumors associated with the syndrome is yet to be determined. Improved understanding of the BAP1-TPDS is crucial for appropriate clinical management of BAP1 germline variant carriers and their families, including genetic counseling and surveillance for new tumors. Methods We collated germline variant status, tumor diagnoses, and information on BAP1 immunohistochemistry or loss of somatic heterozygosity on 106 published and 75 unpublished BAP1 germline variant-positive families worldwide to better characterize the genotypes and phenotypes associated with the BAP1-TPDS. Tumor spectrum and ages of onset were compared between missense and null variants. All statistical tests were two-sided. Results The 181 families carried 140 unique BAP1 germline variants. The collated data confirmed the core tumor spectrum associated with the BAP1-TPDS and showed that some families carrying missense variants can exhibit this phenotype. A variety of noncore BAP1-TPDS -associated tumors were found in families of variant carriers. Median ages of onset of core tumor types were lower in null than missense variant carriers for all tumors combined (P < .001), mesothelioma (P < .001), cutaneous melanoma (P < .001), and nonmelanoma skin cancer (P < .001). Conclusions This analysis substantially increases the number of pathogenic BAP1 germline variants and refines the phenotype. It highlights the need for a curated registry of germline variant carriers for proper assessment of the clinical phenotype of the BAP1-TPDS and pathogenicity of new variants, thus guiding management of patients and informing areas requiring further research.
