Normal moles are easy to call and melanoma is easy to spot, but what about in between these conditions? Skin cancer is not a light switch, on/off, but rather a spectrum of atypia leading up to melanoma

  2. If these structures are distributed symmetrically (at least in one axis) and in an organized manner, the lesion will usually prove to be a dysplastic nevus on biopsy However, if distributed asymmetrically, or in a disorganized manner then the diagnosis of melanoma must be considered understanding dysplastic nevi can share the same dermoscopic features of melanoma and, therein lies the knotty.
  3. Atypical nevi, also known as dysplastic nevi, are benign acquired melanocytic neoplasms. Atypical nevi share some of the clinical features of melanoma, such as asymmetry, irregular borders, multiple colors, and diameter >5 mm (picture 1A). They occur sporadically or in a familial setting
  4. What is a Dysplastic Naevus? A dysplastic naevus is a type of mole that looks quite different from the common mole. These moles may be inherited and some people may be genetically susceptible to developing a very large number of these moles on their skin, which is then referred to as Dysplastic Naevi Syndrome

Dysplastic Nevus - Causes, Diagnosis & Treatment CT

Dysplastic nevus (or Clark's nevus) is a benign, rare, atypical mole. The term atypical refers to a mole that is precancerous. Dysplastic nevus is larger than a normal mole and possesses deformed borders that are hazy and vary in color from tan, to brown or pink kongenitalt nevus - i dermis, subkutis, muskler, nerver och kärl. Det finns även speciella former av melanocytära nevi, exempelvis: Spitz nevus - ofta rosa, kupolliknande, hos barn, kan försvinna spontant efter några år ; Reeds nevus - variant av Spitz nevus men mörkbrunt till svar The lifetime transformation risk of an average dysplastic nevus into melanoma is estimated at 1 in 10 000, though risk likely varies with grade of atypia. 7 In addition, excision is sometimes performed to eliminate risk of a recurrent nevus, a benign lesion that rarely may be difficult to distinguish from melanoma. 8 Disadvantages of excision include risks of scarring and surgical complications and utilization of health resources A severely dysplastic nevus is indistinguishable from early melanoma. Very often these lesions show considerable irregularity of edge and irregularly irregular colour. The differentiation between a moderate and severely dysplastic nevus is one of degree. Mildly dysplastic nevi can be observed The dysplastic nevus has atypical features in and of itself, which become even more compounded when the lesion recurs in the dermoepidermal junction following inadequate resection by shave excision. The use of Monsel's solution to achieve hemostasis at the biopsy site can itself also produce a clinically irregular area of hyperpigmentation, accompanied by a pathologic pigmented and cellular.
