Fig 1 Clinical and histopathologic features of congenital hypertrichotic melanoneurocytoma. A, Left side of the face is fuller than the right and shows a well-delineated pale brown tumor with increased fine light-colored hair, especially of the forehead area. B, Slightly elevated, tan plaque with dense overlying hypertrichosis extending onto forehead. C, Histologic evaluation of lesional skin shows nests of typical melanocytes at the dermoepidermal junction transitioning to spindle cells with wavy nuclei (hematoxylin and eosin stain; 200×). D, Histologic evaluation of lesional skin shows nodular collections of spindle cells in the deep dermis resembling a plexiform neurofibroma. (A and B, Hematoxylin-eosin stain; original magnification: ×200.).
