“…Although the “ugly duckling” is usually a sign typical of melanoma [7], all existing melanocytic lesions must undergo dermoscopic evaluation, regardless of their location and size. According to Bono et al melanomas are more frequently diagnosed among minor melanocytic lesions (less than 3 mm in size) than among those of greater diameter, which usually spark more concern among patients [8,9]. So-called “micromelanomas” in the form of foci measuring less than 3 mm in diameter constituted 2.4% of all examined melanomas (22 of 924 cases of primary foci of melanoma) [8].…”

Dermoscopy is a useful, widely used tool for examining pigmented lesions, especially helpful in cases of an uncertain nature. Nevertheless, doctors may experience diagnostic difficulties while using this method. An example of this may be found in the examination of subcorneal hematoma, dark nevi with black lamella or lesions of acral volar skin. In such cases, a few diagnostic tricks have proven to be helpful in achieving diagnostic accuracy.This paper reviews various methods of performing dermoscopy, suggesting a number of simple, yet helpful tests. These include the adhesive tape test, the skin scraping test and the ink furrow test. The adhesive tape test is helpful in differentiating between dark melanocytic nevi and melanoma. Hematoma may be more easily differentiated with the use of the so-called skin scraping test. The confirmation of benign and melanocytic lesions of acral volar skin, on the other hand, is more accurate when using the ink furrow test. These methods have been discussed here based upon a series of literature reviews, the authors’ own experience and, also, iconography.The present article describes novel methods used in dermoscopy, helping to bring about a faster, more accurate diagnostics of those lesions which have proven to be more difficult to recognize. Helpful tricks, such as have been known to professional literature, as well as the authors’ own experience (for instance, applying urea cream to hyperkeratotic lesions or using photographs of skin lesions taken with the aid of a mobile phone camera – all prior to surgery) will surely be considered beneficial to the practitioner, be it dermatologist or any other physician.

“…The meanings of the A, B, C, and E in the Georgia approach are unchanged from usual use: “A” for “Asymmetry,” “B” for “Border irregularity,” “C” for “Color variation,” and “E” for “Evolving” unlike other lesions. What is critical to the utility of the ABCDE criteria, however, is the change of the “D” to signify “Dark” and not “6 mm Diameter.” With this change, and without altering the familiar mnemonic, the criterion never present in the earliest melanomas is replaced by the single criterion that characterizes many early melanomas [11,16,17]. It can now be stated more accurately that most melanomas have one or more of the ABCDE criteria and that the criteria are relevant to the diagnosis of early melanomas.…”

A unifying approach to the clinical diagnosis of melanoma including “D” for “Dark” in the ABCDE criteria

Current clinical approaches to melanoma diagnosis have not been associated with a decrease in mortality from this cancer. The components of the new approach presented are, first, a screening examination to look for any lesion that stands out because of being dark, different, or changing; second, when a single lesion is recognized to be of concern for any reason, that lesion is then evaluated in more detail utilizing the ABCDE criteria, with the “D” signifying “Dark” and not “6 mm Diameter” in this mnemonic; and, third, additional discussion of the “ugly duckling” sign and of the recognition of nodular melanomas. Since the Georgia Society of Dermatology and Dermatologic Surgery was the first state or national society to endorse this approach, I refer to it as the Georgia approach.

“…Asymmetry is a criterion for such diagnoses (described in clinical and dermoscopic ABCD rules), but MM lesions smaller than 3 mm in diameter may be symmetrical or asymmetrical. 10-12 We should also remember that small lesions may not develop the spectrum of clinical, dermoscopical, and histopathological characteristics. Hence, careful surveillance, especially in risk groups, is justified.…”

The concern about malignant skin neoplasms leads to the excision of smaller lesions. This study on small melanocytic lesions aims to evaluate the range of possible histopathological diagnoses, describe histopathological aspects, and assess the usefulness of serial histological sections. We performed a cross-sectional descriptive histopathological study examining 76 pigmented skin lesions up to 6 mm in diameter. Histopathological diagnoses included atypical melanocytic nevi (n=38), common melanocytic nevi (n=18), atypical lentiginous melanocytic hyperplasia with architectural features of atypical melanocytic nevi (n=7), lentigo simplex (n=2), and malignant melanoma (n=1). Ten cases were non-diagnostic. Cytological atypia was not an exclusive finding of atypical lesions. Examination of serial sections did not change histopathological impression. Early detection of malignant melanoma is important, but clinical and dermoscopy exams may be leading to the resection of a great number of benign lesions. Strict attention to histopathological criteria results in a large number of non-diagnostic cases.

Micro-Melanoma Detection. A Clinical Study on 22 Cases of Melanoma with a Diameter Equal to or Less than 3 MM

Abstract: Dermoscopy appears to be an efficient aid to the diagnosis of micro-melanomas, provided that clinicians are aware of this type of lesion and maintain the index of suspicion at a high level.
