Leaf-like areasBrown to gray/blue discrete linear or bulbous structures coalescing at a common off center base creating structures that resemble a leaf-like pattern. are seen as brown to gray-blue discrete bulbous blobs that often form a pattern shaped like a leaf. They can sometimes appear as tan, broad, and fuzzy streakslines radial (always at periphery) streaks Reed nevus melanoma recurrent nevus at the periphery of a lesion. In the absence of a pigment networkGrid-like pattern consisting of interconnecting pigmented lines surrounding hypopigmented holes., they are highly suggestive of pigmented basal cell carcinomas.

Histopathologically, they represent dermal nodular aggregates of pigmented basal cell carcinomaThis glossary term has not yet been described.. [1]

  1. Lallas et al.: DermoscopyThe examination of [skin lesions] with a 'dermatoscope'. This traditionally consists of a magnifier (typically x10), a non-polarised light source, a transparent plate and a liquid medium between the instrument and the skin, and allows inspection of skin lesions unobstructed by skin surface reflections. Modern dermatoscopes dispense with the use of liquid medium and instead use polarised light to cancel out skin surface reflections. in the diagnosisis the identification of the nature and cause of a certain phenomenon. Diagnosis is used in many different disciplines with variations in the use of logic, analytics, and experience to determine "cause and effect". In systems engineering and computer science, it is typically used to determine the causes of symptoms, mitigations, and solutions and managementThis glossary term has not yet been described. of basal cell carcinomais the most common skin cancer, and one of the most common cancers in the United States.[1] While BCC has a very low metastatic risk, this tumor can cause significant disfigurement by invading surrounding tissues.
