Agminated melanocytic nevus is an uncommon type of mole, characterized by a local group of macular or papular pigmented lesions, well demarcated, without a common pigmented background. This pattern has also been associated with Spitz nevi, dysplastic melanocytic nevi, and non-melanocytic lesions.We describe the onset of an acquired agminated melanocytic nevus after dabrafenib treatment. Our cas...

Linear epidermal nevi frequently follow the lines of Blaschko and may be confused with the verrucous stage of incontinentia pigmenti. 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...

Becker's nevus is a unilateral hyperpigmented area of skin with geographical borders. It is usually located on shoulders, anterior chest, scapular region and upper arms. Sometimes it shows evidence of androgen hypersensitivity and co-localizing with other developmental anomalies. We report a 12-year-old girl with clinical and histopathological findings compatible with Becker's nevus on he...

  Absract   Intracranial invasion of cellular blue nevus (CBN) from the skin is extremely rare   and such a condition with malignant transformation is even rarer. A case of   meningeal melanoma with malignant transformation which was derived from an Ota   nevus is presented in this report.   A21-year-old man with a neurocutaneous syndrome since childhood was referred   with headache and mild le...

I read with interest the paper by Maldonado et al. ( 1 ) investigating the distribution of BRAF mutations across different melanoma types. One of the questions addressed by the authors was whether cutaneous melanomas with a BRAF mutation arose from preexisting melanocytic nevi. In an analysis of 46 lesions, they found melanomas with an associated nevus to have only a slightly higher prevalence ...

A 9-year-old boy had had a large nevus of the scalp since birth. When he was 3 years old, the nevus was excised. The histologic diagnosis was cellular blue nevus. Two years later a follow-up CT scan showed a high-density mass in the base of right middle cranial fossa (Fig . 1). Coronal CT scan showed an extracranial extension of the tumor through the right petrosal bone. Partial removal of the ...

OBJECTIVE To report the clinical evolution and handling of a Spitz nevus, from its initial flat feature to becoming an irregular, nodular, reddish lesion. CASE DESCRIPTION Female child, phototype II, with a small congenital nevus on the left lower limb and other sustained small nevi. The patient went through annual clinical and dermoscopic evaluations between the ages of three and seven, peri...

AIM The aim of this study is to report a clinical case of oral nevus. BACKGROUND Nevus is a congenital or acquired benign neoplasia that can be observed in the skin or mucous membranes. It is an uncommon condition in the oral mucosa. When it does occur, the preferred location is on the palate, followed by the cheek mucosa, lip and tongue. CASE REPORT In this case study, we relate the diagno...

Mucinous nevus is a very rare entity and can be classified as both a cutaneous mucinosis and a connective tissue nevus. We describe the clinicopathologic features of an unusual case of mucinous nevus in a 9-year-old Taiwanese boy who presented with multiple grouped flesh-colored nodules with band-like distribution on his right thigh since birth. Histopathological examination of the skin lesion ...

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...
