Aim. Secondary tumor rarely develops from epidermal nevus. We present a case of a metastasizing squamous cell carcinoma that developed in a solitary epidermal nevus. Case Report. An 82-years old Japanese female was presented with a red tumor on the left axilla. She reported that the tumor developed in a congenital epidermal nevus. A biopsy of the tumor showed that a well-differentiated squamous...
Verrucous epidermal nevi are hamartomatous lesions of the epidermis that, unlike other epidermal nevi (such as sebaceous nevus or nevus comedonicus), are rarely associated with malignant neoplasms. The majority of squamous cell carcinoma develop in linear or multiple epidermal nevus and rarely in solitary epidermal nevus. In general, the prognosis is favorable. We report a case of well-differen...
Here we report a boy with epidermal nevus syndrome associated with brainstem and cerebellar malformations and neonatal medulloblastoma. The patient had epidermal nevi and complicated brain malformations including macrocephaly with polymicrogyria, dysmorphic and enlarged midbrain tectum, enlarged cerebellar hemispheres with small and maloriented folia. The patient died after surgical resection o...
Nevus comedonicus is an uncommon variant of adnexal hamartoma and is considered a rare subtype of epidermal nevi. It was first described in 1895 by Kofmann who used the term “comedo-nevus”. It manifests as a group of closely dilated follicular openings with dark keratin plugs resembling comedones. Both unilateral and bilateral distributions are seen. The face is the most commonly affected site ...
The intention of this review on nevus comedonicus (NC) is to update on clinical features, pathogenesis, and therapy. NC is a rare epidermal nevus type. It is part of the nevus comedonicus syndrome, a neurocutaneous disorder with ocular, skeletal, and central nervous symptoms. Recently, acne-related signaling pathways and somatic mutations of tyrosine kinase receptors have been identified and ma...
Epidermal Nevus Associated with Cerebral and Ocular MR Imaging Abnormalities This letter focuses on Schimmelpenning syndrome (SS), a neurocutaneous disorder related to epidermal nevus syndromes and characterized by craniofacial nevus, neurologic anomalies, and ocular pathology. We discuss clinical and MR imaging features of a 10-year-old boy, pointing out the etiopathologic substratum of this c...
Becker's nevus syndrome is part of the epidermal nevus syndromes and has been described with a phenotype that includes Becker's nevus, ipsilateral breast hypoplasia, and variable skeletal malformations. It is more frequent in males than in females (5 : 1) but is more relevant in females. The diagnosis is clinically based and the skin lesion must be present and no other numbered criteria have be...
