Cutaneous malignant melanoma 1

Malignant melanoma is a neoplasm of pigment-producing cells called melanocytes that occurs most often in the skin, but may also occur in the eyes, ears, gastrointestinal tract, leptomeninges, and oral and genital mucous membranes (summary by Habif, 2010). Genetic Heterogeneity of Susceptibility to Cutaneous Malignant Melanoma The locus for susceptibility to familial cutaneous malignant melanoma-1 (CMM1) has been mapped to chromosome 1p36. Other CMM susceptibility loci include CMM2 (155601), caused by variation in the CDKN2A gene (600160) on chromosome 9p21; CMM3 (609048), caused by variation in the CDK4 gene (123829) on chromosome 12q14; CMM4 (608035), mapped to chromosome 1p22; CMM5 (613099), caused by variation in the MC1R gene (155555) on chromosome 16q24; CMM6 (613972), caused by variation in the XRCC3 gene (600675) on chromosome 14q32; CMM7 (612263), mapped to chromosome 20q11; CMM8 (614456), caused by variation in the MITF gene (156845) on chromosome 3p13; CMM9 (615134), caused by variation in the TERT gene (187270) on chromosome 5p15; and CMM10 (615848), caused by mutation in the POT1 gene (606478) on chromosome 7q31. Somatic mutations causing malignant melanoma have also been identified in several genes, including BRAF (164757), STK11 (602216), PTEN (601728), TRRAP (603015), DCC (120470), GRIN2A (138253), ZNF831, BAP1 (603089), and RASA2 (601589). A large percentage of melanomas (40-60%) carry an activating somatic mutation in the BRAF gene, most often V600E (164757.0001) (Davies et al., 2002; Pollock et al., 2003). [from OMIM]

Malignant melanoma of skin

A primary melanoma arising from atypical melanocytes in the skin. Precursor lesions include acquired and congenital melanocytic nevi, and dysplastic nevi. Several histologic variants have been recognized, including superficial spreading melanoma, acral lentiginous melanoma, nodular melanoma, and lentigo maligna melanoma. [from NCI]

Peutz-Jeghers syndrome

Peutz-Jeghers syndrome (PJS) is an autosomal dominant condition characterized by the association of gastrointestinal polyposis, mucocutaneous pigmentation, and cancer predisposition. Peutz-Jeghers-type hamartomatous polyps are most common in the small intestine (in order of prevalence: in the jejunum, ileum, and duodenum) but can also occur in the stomach, large bowel, and extraintestinal sites including the renal pelvis, bronchus, gall bladder, nasal passages, urinary bladder, and ureters. Gastrointestinal polyps can result in chronic bleeding and anemia and also cause recurrent obstruction and intussusception requiring repeated laparotomy and bowel resection. Mucocutaneous hyperpigmentation presents in childhood as dark blue to dark brown macules around the mouth, eyes, and nostrils, in the perianal area, and on the buccal mucosa. Hyperpigmented macules on the fingers are common. The macules may fade in puberty and adulthood. Individuals with Peutz-Jeghers syndrome are at increased risk for a wide variety of epithelial malignancies (colorectal, gastric, pancreatic, breast, and ovarian cancers). Females are at risk for sex cord tumors with annular tubules (SCTAT), a benign neoplasm of the ovaries, and adenoma malignum of the cervix, a rare aggressive cancer. Males occasionally develop large calcifying Sertoli cell tumors (LCST) of the testes, which secrete estrogen and can lead to gynecomastia, advanced skeletal age, and ultimately short stature, if untreated. [from GeneReviews]

Malignant melanoma

Melanoma is the most serious type of skin cancer. Often the first sign of melanoma is a change in the size, shape, color, or feel of a mole. Most melanomas have a black or black-blue area. Melanoma may also appear as a new mole. It may be black, abnormal, or ugly looking.. Thinking of ABCDE can help you remember what to watch for:. - Asymmetry - the shape of one half does not match the other. - Border - the edges are ragged, blurred or irregular. - Color - the color is uneven and may include shades of black, brown and tan. - Diameter - there is a change in size, usually an increase. -Evolving - the mole has changed over the past few weeks or months. Surgery is the first treatment of all stages of melanoma. Other treatments include chemotherapy and radiation, biologic, and targeted therapies. Biologic therapy boosts your body's own ability to fight cancer. Targeted therapy uses substances that attack cancer cells without harming normal cells.

EPIDERMODYSPLASIA VERRUCIFORMIS

Epidermodysplasia verruciformis (EV) is a rare genodermatosis associated with a high risk of skin cancer (Ramoz et al., 2000). EV results from an abnormal susceptibility to specific related human papillomavirus (HPV) genotypes and to the oncogenic potential of some of them, mainly HPV5. Infection with EV-associated HPV leads to the early development of disseminated flat wart-like and pityriasis versicolor-like lesions. Patients are unable to reject their lesions, and cutaneous Bowen carcinomas in situ and invasive squamous cell carcinomas develop in about half of them, mainly on sun-exposed areas. [from OMIM]

Neuroendocrine neoplasm

Tumors whose cells possess secretory granules and originate from the neuroectoderm, i.e., the cells of the ectoblast or epiblast that program the neuroendocrine system. Common properties across most neuroendocrine tumors include ectopic hormone production (often via APUD CELLS), the presence of tumor-associated antigens, and isozyme composition. [from MeSH]

Hereditary cancer-predisposing syndrome

The condition of a pattern of malignancies within a family, but not every individual's necessarily having the same neoplasm. Characteristically the tumor tends to occur at an earlier than average age, individuals may have more than one primary tumor, the tumors may be multicentric, usually more than 25 percent of the individuals in direct lineal descent from the proband are affected, and the cancer predisposition in these families behaves as an autosomal dominant trait with about 60 percent penetrance. [from MeSH]
