Phakomatosis pigmentovascularis (PPV) is a syndrome characterized by the association of a vascular nevus with a congenital pigmented lesion (epidermal nevus, nevus spilus, and dermal melanocytosis). There are different types of PPV according to the pigmentary nevus associated with the vascular malformation. Patients may present only the cutaneous condition or have systemic manifestations, among them, trauma, neurological and ophthalmological disorders. Read More

An 8-month-old Caucasian infant with neurofibromatosis type 1 presented with a congenital plexiform neurofibroma and multiple café au lait spots. A pale area surrounded one of the café au lait spots located on the left gluteus in the area of dermal melanocytosis. This halolike phenomenon results from the disappearance of the Mongolian spot around the café au lait spots, revealing normal pigmented skin. Read More

Congenital dermal melanocytosis (CDM) is a birthmark composed of macular blue-grey hyperpigmentation commonly observed in the lumbosacral region of infants. Generally resolving by childhood, it is traditionally considered a benign condition, but it may be a sign of underlying lysosomal storage disease. We report a case of biopsy-confirmed CDM in a 2-month-old girl of Brazilian descent later diagnosed with infantile GM1 gangliosidosis. Read More

Dermal melanocytosis refers to a spectrum of benign melanocytic proliferations that includes Mongolian spot, nevus of Ota and nevus of Ito. These lesions most commonly occur in persons of Asian or African descent and are often present at birth or develop during childhood. Very rarely, dermal melanocytoses undergo malignant transformation. Read More

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. Read More

Dermal melanocytoses comprise a variety of congenital and acquired conditions characterized by a sparse population of intradermal dendritic, variably pigmented, spindle-shaped melanocytes. While Mongolian spot, Ota's and Ito's nevi are usually present at birth or appear around puberty; acquired dermal melanocytoses that appear in adult life are extremely rare. They include the facial lesions of acquired bilateral nevus of Ota-like macules, also named Hori's nevus, and the acquired unilateral nevus of Ota, also known as Sun's nevus. Read More

While most dermal melanocytoses are congenital or have an onset in early childhood, there is a group which is clearly acquired, with an onset in adult life. While the Mongolian spot typically disappears in childhood, other dermal melanocytoses persist for life. A brief review of the clinical spectrum of the dermal melanocytoses is undertaken and three illustrative cases are described: a case of congenital naevus of Ota, a case of acquired bilateral naevus of Ota-like macules, and an unusual case of a congenital dermal melanocytotic lesion on the left had which began to spread in adulthood.

We describe a plaque-type blue nevus that had been present since birth on the right cheek of a 22-year-old man. It was characterized by several dark blue macules and papules with intervening areas of faint blue discoloration. Histologic examination showed a common blue nevus and a mongolian spot-like dermal melanocytosis in the dark blue and intervening faint blue pigmentary lesions, respectively. Read More

Background: Dermal melanocytosis is characterized by the presence of melanocytes in the dermis. There are several morphologic forms, such as the blue nevus, the mongolian spot, the nevus of Ota, and the nevus of Ito. In this article, we report an unusual case of dermal melanocytosis. Read More
