Dermoscopy of superficial melanoma By the time in situand invasivesuperficial spreading melanoma (SSM) is recognised as a changing or distinctive lesionby the patient or their doctor, it is often large (>6mm). Characteristically, superficial melanoma is asymmetricaland irregular in shape and structure. Superficial spreading melanomas in Australia are now detected earlier when tumours are thinner, resulting in a reduction in deaths from this subtype. 4,8 However, we are less effective in detecting melanoma subtypes that have an atypical clinical appearance, such as nodular melanoma, desmoplastic melanoma and acral lentiginous melanoma. As the study aimed to explore differences in tumor thickness at diagnosis between nodular melanoma (NM) and superficial spreading melanoma (SSM), only patients with these. Dermoscopy. Flashcards.

Lentigo maligna and superficial spreading melanoma are different in their in situ phase An. Figure 1 Superficial spreading melanoma viewed with dermoscopy (large panel) and with the unaided eye (inset panel).

Dermoscopy is not necessary if the lesion has the typical clinical appearance of melanoma. A suspected melanoma should be surgically removed with a 2 to 3-mm margin (excision biopsy) and sent to a pathology laboratory for examination under a microscope (histology). A small biopsy is best avoided, except in unusually large lesions. The accuracy of dermoscopy for the detection of invasive melanoma or atypical intraepidermal melanocytic variants was reported in 86 datasets; 26 for evaluations conducted in person (dermoscopy added to visual inspection), and 60 for image-based evaluations (diagnosis based on interpretation of dermoscopic images).

Dermoscopy can be very helpful in distinguishing superficial spreading melanoma from other skin lesions, such as melanocytic naevi, . Superficial spreading melanoma is also known as pagetoid melanoma which characterized by a proliferation of atypical melanocytes singly and in nests in all layers of the epidermis. Superficial spreading melanoma is the most common type of melanoma, accounting for around 70 percent of all cases. It starts growing along the top layer of the skin. Over time it penetrates. Been reassured at previous examinations. Histology reported as Sections show a small focus of level 2 (0.3mm thick) superficial spreading melanoma arising in a larger level 1 lesion. There is no ulceration, dermal mitoses or significant regression but there is a patchy mild to moderate lymphocytic infiltrate.

MM is the sixth most common cancer in the UK1 with a crude incidence of 15.9100 000, equating to 9500 new cases per annum.2 Breslow thickness, the thickness of a melanoma in millimetres measured from the top of the granular layer of the epidermis,3 is the most important prognostic indicator.4 Excision of.
