| In general, benign lesions are round and symmetric, while melanomas are asymmetric. |
|
| Sebaceous cysts, fibromas, papillomas, adenomas, sarcomas, carcinomas, and melanomas also have been reported. |
|
| Pigmented primary intracranial tumors other than meningeal melanocytomas and melanomas are rare. |
|
| Malignant melanomas are derived from epidermal melanocytes, and frequently arise from pre-existing pigmented lesions such as moles. |
|
| There is a definite link between sunbathing and the incidence of malignant melanomas. |
|
| Although they make up the smallest percentage of all skin cancers, melanomas cause the greatest number of deaths. |
|
| The risk for developing metastatic lesions from primary cutaneous melanomas increases with tumor thickness. |
|
| The authors also used flow cytometry to characterize melanomas of varying invasiveness. |
|
| The data show that the growth in dermatological surgeons excising primary melanomas has had no adverse affect on patient outcome. |
|
| These patients are also at risk for second cancers, including bone, brain, leukemia and lymphoma, melanomas, and soft tissue sarcomas. |
|
| Vertical-phase tumors are more likely to metastasize than radial melanomas. |
|
| Overall, late metastases to the spleen were seen more often in melanomas, choriocarcinomas, and breast carcinomas. |
|
| The oral melanomas are more likely to be flat and thin, amelanotic, and may be detected at a noninvasive or early invasive stage. |
|
| Delirium and dementia may arise from brain metastases, which usually originate from lung cancer but also from tumours of the breast and alimentary tract and melanomas. |
|
| The development of actinic keratosis or malignant melanomas are among the possible serious consequences. |
|
| Further, the policy exclusion for melanomas of the skin with reference to Clark Level staging does not apply to choroidal melanoma. |
|
| Keratoses, carcinomas and melanomas are simply different stages and types of infection that can occur inside a fold crossing. |
|
| Differentiating between seborrheic keratoses and melanomas is a challenge. |
|
| Splenic metastases associated with melanomas, choriocarcinomas, and breast carcinomas were often detected long after primary tumors were diagnosed. |
|
| Of the 9 metastatic melanomas, 5 were melanotic and 4 were amelanotic. |
|
|
|
| Malignant melanomas may start as pigmented birthmarks but can also occur spontaneously on previously completely pristine skin. |
|
| About half of malignant skin melanomas arise from pre-existing moles. |
|
| Pineal melanomas can present as either melanotic or amelanotic MRI patterns. |
|
| Analysis of data on second primary melanomas has enabled the importance of risk factors such as sun exposure, skin and eye colour, and skin type to be calculated. |
|
| To catch these melanomas at an early stage you need to be attentive to any moles that change in appearance or shape, colour or thickness and do not hesitate to go and see a doctor. |
|
| The ri-derma® dermatoscope offers general physicians and specialists a reliable method of dermatoscopic screening and early identification of malignant melanomas. |
|
| Perhaps most seriously, neither Ephreim nor his sister Faustine, who speaks in a whisper with her head bowed, has received any medical attention for the melanomas that liberally speckle their arms and faces. |
|
| Reporting in the British Journal of Cancer, they say it works by measuring the density of the lymph vessels around malignant melanomas. |
|
| To validate the modified protocol, 44 benign nevi and 30 non-lentigo maligna melanomas were also examined. |
|
| Use of an enterobacterium OmpA protein, combined with the peptide of sequence SEQ ID No. 3 ELAGIGILTV, for preparing a pharmaceutical composition intended for treating or preventing malignant melanomas. |
|
| One can distinguish the epitheliomas, which appear in the form of little round white or pink-coloured elevated areas or persistent scabs, and the malignant melanomas appearing on healthy skin or from a change in a mole. |
|
| An autograft occurs when tissue is transplanted from one site to another site on a patient, such as for skin grafts after the removal of melanomas and nonmelanoma skin cancers. |
|
| Disturbances of vision are the most common symptom, but, if the tumour is neglected, choroidal melanomas may enlarge and cause inflammation and raised pressure within the eye. |
|
| Most choroidal melanomas are initially asymptomatic, only becoming evident as the tumor enlarges and causing symptoms such as blurred vision, distortion of vision, flashing lights, bulging eyes and retinal detachment. |
|
| Australian researchers have conducted a randomised trial on more the 1,600 Queesland residents and found that participants in the control group developed twice more melanomas than those applying sunscreen every day developed. |
|
| For the reasons stated above, patients and healthcare providers are advised to monitor for melanomas frequently and on a regular basis when using PROLOPA for any indication. |
|
| After 15 years, the number of people who developed melanomas from the discretionary sunscreen group was twice that of the group who had applied daily sunscreen in the trial. |
|
| A computer algorithm that can extract meaningful information from X-ray data gathered by the ROSAT satellite can powerfully assist the physician in the diagnosis of initial malignant melanomas. |
|
| This type of treatment is utilised in small or medium melanomas. |
|
| This acts as a deterrent to predator fish, but is also known for having properties against cancer of the kidney and the pancreas, and non-Hodgkin's leukemia, melanomas and lymphomas. |
|
|
|
| However, it is not considered necessary for most ocular melanomas due to the near certainty of the diagnosis from clinical appearance and the use of ancillary tools such as photographs and ultrasound. |
|
| The most common cancers to involve the leptomeninges are breast cancer, lung cancer, and melanomas. |
|
| Immunoprofile of MITF, tyrosinase, melan-A, and MAGE-1 in HMB45-negative melanomas. |
|
| It is also important to recognize that spindle and desmoplastic melanomas have higher propensity for neurotropism, thus resulting in high local recurrence. |
|
| To appropriately consider the concept of melanoma vertical growth, it is important to first understand the nature of what antecedes it in most melanomas, namely radial growth. |
|
| In a 2004 study of 884 patients with thin melanomas, Gimotty et al demonstrated that both tumorigenicity and mitogenicity were independently predictive of survival. |
|
| Melanomas can occur anywhere on the body but are most frequently found on the upper backs and legs. |
|
| Melanomas can be junctional, intradermal, or compound according to whether they grow in the basal layer of the skin, in the true skin or in both. |
|
| Melanomas and other skin cancers usually have irregular shapes. |
