Acral Pigmented Spitz Nevus That Clinically Mimicked Acral Lentiginous Malignant Melanoma

Acral pigmented spitz nevus that clinically mimicked acral lentiginous malignant melanoma.

Pigmented Spitz nevus is a benign melanocytic skin lesion with distinct clinical features and it is frequently found on the extremities. However, it rarely occurs on acral area of the body, and such a case has not yet been fully documented. We present a case of acral pigmented Spitz nevus occurring on the foot, and this mimicked acral lentiginous malignant melanoma. Clinicians should be well aw...

Management of Acral Lentiginous Melanoma

Cutaneous malignant melanoma is the most common cause of mortality from skin cancers in Caucasian populations. The incidence rates of malignant melanoma show considerable varia‐ tion worldwide. Annual incidence rates per 100,000 people vary between about 40 in Australia and New Zealand to about 20 in the United States [1,2]. In contrast, a significantly lower inci‐ dence rate has been reported ...

Progression from Acral Lentiginous Melanoma in situ to Invasive Acral Lentiginous Melanoma.

Acral lentiginous melanoma (ALM) is the most common type of cutaneous melanoma in Asians. The very early stage of ALM demonstrates only a proliferation of a few atypical melanocytes within the epidermis, and has been termed ALM in situ. A 74-year-old male patient presented with a pigmented lesion on the left great toe for 12 years, which had initially showed only a few scattered hyperplastic at...

Comparison of dermatoscopic images of acral lentiginous melanoma and acral melanocytic nevus occurring on body weight-bearing areas

BACKGROUND Because body weight-bearing produces a shift in the horny layer, acral melanocytic nevus on the body weight-bearing area of the sole showed a regular fibrillar pattern (FP) due to slanting of the melanin columns in the horny layer. On the other hand, acral lentiginous melanoma (ALM) on the body weight-bearing area of the sole tended to show irregular fibrillar pattern showing rather ...
