We report phakomatosis pigmentovascularis (PPV) detected in a 40- year-old male characterized by the presence of a port-wine stain in the background of aberrant Mongolian spots covering the back, nevus of Ota, ocular melanosis, epidermal nevus and a scaly patch with the diagnosis of discoid lupus erytematosus. These associations have not been reported yet.

Becker's nevus, also called Becker's melanosis or pigmented hairy epidermal nevus, is a benign cutaneous hamartoma characterized by hyperpigmented macule usually with hypertrichosis. It is rarely associated with neurofibromatosis. We report a 2 1⁄2 yrs old male child with coexistent congenital Becker’s nevus and type 1 neurofibromatosis.

Neurocutaneous melanosis is a rare disease belonging to the group of phakomatoses, characterized by presence giant melanocytic nevi on skin and infiltration parenchyma meninges, as well high risk neurological complications malignancy. Purpose - analyze information modern specialized literature etiology, pathogenesis, approaches diagnosis treatment orphan neurocutaneous (Rokitansky's disease) de...

BACKGROUND Melanosis is the most common cause of mucosal pigmentation and can be clinically difficult to differentiate from early melanoma (MM). Dermoscopy can help in the distinction between melanosis and MM, but in some instances, melanoses may exhibit overlapping features with MM such as the presence of grey colour. OBJECTIVE We sought to evaluate whether reflectance confocal microscopy (R...

BACKGROUND Anthranoid laxatives are the most commonly used purgatives in the therapy of acute and chronic constipation. Recent experimental data and a prospective cohort study provide evidence of a possible risk of anthranoid use for the development of colorectal neoplasms. MATERIALS AND METHODS We performed a prospective case control study at the University of Erlangen to investigate the ris...

We describe a patient with progressive hyperpigmentation of the skin and gas-trointestinal melanosis. The pigmented lesions in the stomach and duodenum served as a diagnostic sign of recurrent disease, 26 years after excision of melano-ma of the skin. A barium swallow and gastroduodenos-copy were performed in a healthy 63-year-old man who had been suffering from vague abdominal symptoms for a f...

Mimicry and melanism in Lepidoptera provided the first convincing examples of natural selection in action. Genetic analysis has now shown that, surprisingly, mimicry in Heliconius butterflies and melanism in peppered moths are switched at precisely the same gene: cortex.

Neurocutaneous melanosis (NCM) is a rare congenital disease that is characterized by the presence of large or multiple congenital melanocytic nevi and melanotic lesions of the central nervous system. We report here on the CT and MR imaging findings of an unusual case of NCM that was associated with intraventricular dermoid and Dandy-Walker malformation.

We report phakomatosis pigmentovascularis (PPV) detected in a 40yearold male characterized by the presence of a port-wine stain in the background of aberrant Mongolian spots covering the back, nevus of Ota, ocular melanosis, epidermal nevus and a scaly patch with the diagnosis of discoid lupus erytematosus. These associations have not been reported yet.
