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.
