<\/span>What is the animal type? melanoma<\/span>?<\/span><\/h2>\nMelanoma is a skin Cancer<\/span> that arises from pigment<\/span> cells (melanocytes<\/span>)<\/p>\nAnimal-type melanoma is a very rare form of melanoma with a dark brown \/ black appearance. The diagnosis is made from your histological<\/span> appearance in biopsy<\/span>. The name "animal type" arises from the close similarity with the pigmented<\/span> melanocytic<\/span> tumors found in gray horses. Also known as equine-type melanoma, pigment synthesis melanoma, and pigment pigment. epithelioid<\/span> melanocytoma<\/p>\nAnimal-type melanoma was first described by Darier in 1925.<\/p>\n
<\/span>Who gets animal-type melanoma?<\/span><\/h2>\nAnimal-type melanoma can occur at any age, even during childhood. Some studies have found that it is more common in young adults, but another reported that it is more common in middle-aged and older adults.<\/p>\n
Males and females appear to be equally affected.<\/p>\n
Patients with animal-type melanoma are no more likely than the general population to have well-known risk factors for common types of melanoma (such as fair skin, family history, and sun damage).<\/p>\n
<\/div>\n
<\/span>What does animal type melanoma look like?<\/span><\/h2>\nAnimal-type melanoma can develop anywhere in the body. It arises from normal skin (de novo<\/span>), instead of a pre-existing nevus<\/span> (Mole).<\/p>\nAnimal-type melanoma usually presents as dark brown \/ back papule<\/span> or nodule<\/span>. At the time of diagnosis, it was likely present for a year or more.<\/p>\nIn general, animal-type melanoma has the ABCDE criteria:<\/p>\n
\n- Asymmetry<\/li>\n
- Border irregularity<\/li>\n
- Color variation<\/li>\n
- Diameter more than 6 mm.<\/li>\n<\/ul>\n
The clinic differential diagnosis<\/span> includes blue naevus variants:<\/p>\n\n- Deep penetrating nevus<\/li>\n
- \nCellular<\/span> blue nevus<\/li>\n
- \nEvil one<\/span> blue nevus<\/li>\n
- Epithelioid blue nevus, which may be associated with the Carney complex, a family<\/span> association of skin tumors with cardiac myxoma<\/span> and psammomatous melanotic schwannoma. See myxoma syndromes.<\/li>\n<\/ul>\n
<\/span>What tests should be done?<\/span><\/h2>\nAfter clinical evaluation has suggested a skin injury<\/span> To suspect melanoma, the lesion should be examined with a dermatoscope. The dermoscopic appearance of animal-type melanoma may show an unstructured blue pattern, irregular whitish structures, and irregular, large blood vessels<\/span>.<\/p>\nAfter the injury is removed by excision<\/span> biopsy a histology<\/span> The animal-type melanoma report may report:<\/p>\n\n- Strongly pigmented compound or dermal<\/span> melanocytic tumor<\/span>\n<\/li>\n
- Epithelioid and spindle melanocytes.<\/li>\n
- Malignant or soft cytological appearance<\/li>\n
- Usually low mitotic<\/span> activity and infrequent ulceration<\/span>,<\/li>\n
- There are no features to suggest regression<\/span>.<\/li>\n<\/ul>\n
the pathologist<\/span> It can be difficult to make a definitive diagnosis of melanoma, since the characteristics of animal-type melanoma may resemble those of blue naevi<\/span>. Therefore, there are equivocal and unequivocal cases.<\/p>\n<\/span>What is the treatment for animal type melanoma?<\/span><\/h2>\nConfirmed animal-type melanoma is widely removed, with a clinical margin depending on Breslow thickness<\/span>.<\/p>\nMany centers offer sentinel lymph node<\/span> biopsy if the melanoma has a Breslow thickness of 1 mm or more, or invader<\/span> tumors that are less than 1 mm thick but have ulceration or a mitotic rate of 1 or more.<\/p>\n\n- In a review of 22 cases, Ludgate et al found that patients with equivocal animal-type melanoma were younger and sentinel lymph node biopsy tended to be negative, compared to those with unequivocal animal-type malignant melanoma.<\/li>\n
- Antony et al reported that although animal-type melanoma has a regional tendency lymphatic<\/span> spread, very unlikely to drive remotely metastasis<\/span> and death<\/li>\n<\/ul>\n
<\/div>\n
<\/span>Staging<\/span><\/h2>\nStaging melanoma means finding out if melanoma has spread from its original place on the skin. Most melanoma specialists refer to the American Joint Committee on Cancer (AJCC) cutaneous<\/span> melanoma staging guidelines (2009). In essence, the stages are:<\/p>\n\n\n\n| Stage<\/th>\n | Characteristics<\/th>\n<\/tr>\n |
\n| Stage 0<\/td>\n | \nIn the place<\/span> melanoma<\/td>\n<\/tr>\n\n| Level 1<\/td>\n | Thin melanoma <2 mm de espesor<\/td>\n<\/tr>\n | \n| Stage 2<\/td>\n | Thick melanoma> 2mm thick<\/td>\n<\/tr>\n | \n| Stage 3<\/td>\n | Melanoma spread to involve locals lymph nodes<\/span>\n<\/td>\n<\/tr>\n\n| Stage 4<\/td>\n | Distant metastases have been detected.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/span>What happens at the follow-up?<\/span><\/h2>\nThe main goal of follow-up is to detect recurrences early, but it also offers the opportunity to diagnose a new primary<\/span> melanoma at the earliest possible opportunity. A second invasive melanoma occurs in 5 to 10% of melanoma patients; An unrelated melanoma in situ affects more than 20% of melanoma patients.<\/p>\nThe Australian and New Zealand Melanoma Management Guidelines (2008) make the following recommendations for the follow-up of patients with invasive melanoma.<\/p>\n | | |
