A 41-year-old woman with a complex congenital nevus that possessed features of both a blue nevus and a nevus of Ota is described. She was found to have melanotic hyperpigmentation of the underlying subcutaneous tissue and dura mater. Two separate melanomas developed in the tissues underlying her nevus (one in the subcutaneous tissue and another intracranially, arising from the dura).

PURPOSE To report the clinical and histologic features of combined nevi of the conjunctiva, a type of nevus that is not uncommon in the skin but has rarely been reported in the conjunctiva. METHODS Conjunctival nevi and melanomas from the files of the University of California, San Francisco, eye pathology laboratory were reviewed from 1984 to 1999 for the presence of features of both standard...

The intraoral blue nevus occurs infrequently in children. This case report describes the clinical features of an acquired blue nevus in a 7 year-old girl that involved the palatal mucosa. A differential diagnosis and justification for surgical excision of this oral lesion are discussed.

A 23 year old woman presented with facial pain, a right parotid tumour and iron deficiency anaemia. She had several cutaneous venous swellings and tumours with a similar appearance were found in the large bowel. Histological examination of the parotid tumour and angiography of the skin and gut lesions confirmed that they were venous in origin. The aetiology, classification, and complications of...

Becker nevus syndrome is a phenotype characterized by the fundamental presence of Becker's nevus with ipsilateral hypoplasia of the breast or other skin, skeletal and/or muscular disorders. This syndrome generally originates at birth, intensifies significantly in adolescence and is one of the syndromes that constitute epidermal nevus syndrome. To the best of our knowledge, this is the first cas...

We report a case of blue nevus of the uterine cervix discovered in a cone removed for other reasons. The lesion can be interpreted as a visceral analogue of the cutaneous blue nevus. Histological and Immunohistological studies suggest the melanocytic nature of the lesion.

Dermal melanocytosis is characterized by the presence of ectopic melanocytes in the dermis. The most common forms include the Mongolian spot, blue nevus, nevus of Ota, and nevus of Ito. Some types of dermal melanocytosis do not fit into any of these morphologic categories, however. Our case demonstrated an extensive amount of uniform deep blue patches of nevi with unilateral distribution on the...

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 ...
