Signs and symptoms that your thoracic aortic aneurysm has burst include: Sudden, intense and persistent chest or back pain Pain that radiates to your back Trouble breathing Low blood pressure Loss of consciousness Shortness of breath Trouble swallowing [mayoclinic.org]
Other absolute indications for treatment are the presence of an embolic episode, disabling iliac occlusive disease, coexistence of iliac aneurysm, low back or abdominal pain attributable to the AAA and a growth rate of more than 5 mm/year. [revespcardiol.org]
- Neck Pain
Features may include: a neck lump or neck pain typically >35 years old; and diarrhoea due to raised calcitonin levels. [genomicseducation.hee.nhs.uk]
Skin
- Freckles
It develops from a slow-growing precancerous condition called a lentigo maligna or Hutchinson’s freckle. This looks like a stain on the skin. They are usually slow-growing and less dangerous than the other types of melanoma. [macmillan.org.uk]
Some variants appear then to result in the production of phaeomelanin predominantly, with resultant red hair, freckles and sun sensitivity. [genomel.org]
Fair skin, freckling, and light hair The risk of melanoma is much higher for whites than for African Americans. Whites with red or blond hair, blue or green eyes, or fair skin that freckles or burns easily are at increased risk. [cancer.org]
Etiology The risk of familial melanoma is closely related to a wide range of genetic alterations in susceptibility genes but also appears to be influenced by phenotypic risk factors, such as pigmentation, freckling and nevi and sun reactions but also [orpha.net]
Risk factors for uveal melanoma include advancing age, having a fair complexion, and certain pigmentation conditions like having an ocular nevus or “freckle,” skin pigmentations such as atypical mole syndrome, or increased pigmentation around the eye [cancer.osu.edu]

UV output rating [ edit ] This is one of the most confusing aspects of tanning lamps in North America, as lamps in the US are not rated for their total output, but rather their ratio of UVA to UVB. [en.wikipedia.org]
Confusion exists because some atypical moles cannot be clinically distinguished from melanoma. The clinical and histologic appearances of atypical moles occurring in a familial setting appear to overlap with sporadically occurring atypical moles. [emedicine.medscape.com]
Workup
[…] each participant, information on their skin examination, sun exposure history, medical photographs (both overview and close-up) and blood draw for localizing genetic loci, identifying genes and evaluating phenotype/genotype correlations, constitute the workup [clinicaltrials.gov]
If one of the high-risk indicators, mentioned previously is found, there is reasonable evidence for potential growth and many authorities recommend advancing the workup and obtaining a biopsy. [eyewiki.aao.org]

Given the propensity for mucosal melanoma to disseminate and to exclude metastatic melanoma from a cutaneous primary, a basic metastatic workup should be considered. [ncbi.nlm.nih.gov]

Etiology
Thoracic aortic aneurysms have been historically considered to be caused by etiologic factors similar to those implied in abdominal aortic aneurysms. [hindawi.com]
Etiology FAMMM syndrome has been associated with mutations in the 16p locus of CDKN2A (9p21), a tumor suppressor gene involved in cell cycle inhibition. However, approximately 60% of patients with FAMMM syndrome do not have a CDKN2A mutation. [orpha.net]
