  Acral lentiginous melanoma misdiagnosed as verruca plantaris: A case report
Acral lentiginous melanoma is the most common type of melanoma found in individuals with darkly pigmented skin (natives of Asia, India, Africa, and African-Americans); it also constitutes a smaller proportion of all melanomas found in fair-skinned persons [1, 2, 3, 4].
Acral lentiginous melanoma is found on the digits, palms, soles, dorsum of the foot, and in the subungual area [1, 2, 3, 4, 5, 6, 7].
Acral lentiginous melanoma can be mistaken for a variety of alternative diagnoses, including verruca, corn or callus, eccrine poroma, pyogenic granuloma, ischemic ulceration, mal perforans from a peripheral neuropathy, gangrene, superficial fungal infection, traumatic residual, foreign body, and benign nevus [10, 11, 13].

  Dr. Koop - Melanoma- Health Encyclopedia and Reference
Melanoma is a type of cancer originating from the cells that give color to the skin.
Treatment of melanoma that has not spread beyond the original area of growth (especially if it is thin and has not invaded the primary dermis) is highly effective, and most of these cancers can be cured.
Melanoma that has spread to distant sites is infrequently curable with standard therapy, although long-term survival is occasionally achieved by resection of metastasis.

 eMedicine - Malignant Melanoma : Article Excerpt by: Susan M Swetter, MD
Background: Melanoma is a malignancy of pigment-producing cells (melanocytes) located predominantly in the skin, but also found in the eyes, ears, GI tract, leptomeninges, and oral and genital mucous membranes.
Primary cutaneous melanoma may develop in precursor melanocytic nevi (common, congenital, and atypical/dysplastic types), although more than 60% of cases are believed to arise de novo (ie, not from a preexisting pigmented lesion).
The development of melanoma is multifactorial and appears to be related to multiple risk factors, including fair complexion, excessive childhood sun exposure and blistering childhood sunburns, an increased number of common and dysplastic moles, a family history of melanoma, the presence of a changing mole or evolving lesion on the skin, and, importantly, older age.

 About Melanoma   (Site not responding. Last check: 2007-10-16)
Melanoma is a malignant tumor that originates in melanocytes, the cells which produce the pigment melanin that colors our skin, hair, and eyes and is heavily concentrated in most moles.
Invasive melanomas are the more serious, as they have penetrated more deeply into the skin and may have traveled from the original tumor through the body.
The melanoma can be seen almost anywhere on the body, but is most likely to occur on the trunk in men, the legs in women, and the upper back in both.
