Cutaneous ganglioneuroma within a giant congenital nevus

Two Cases of Giant Congenital Cutaneous Hamartoma: Nevus Sebaceus of Jadassohn and Congenital Melanocytic Nevus

During the normal development of skin, pluripotential cells give rise to keratinocytes, sebaceus glands, hair follicles, apocrine glands and eccrine glands. A hamartoma, or an abnormal mixture of a tissue’s normal components, results from an error in development, among which some show malignant potential. We report two Chinese cases of giant congenital cutaneous hamartoma, a nevus sebaceus of J...

Inflammatory epidermal nevus appears as a line array of pink to red papules usually on the lower limb (Buttock and hip) clinically resembling psoriasis or eczematous dermatitis. But inflammatory epidermal nevus has distinct histopathologic features. We report a c...
