The Effects of an Educational Video on Patient Understanding of Amelanotic Melanoma

JEADV Clinical Practice, EarlyView.
ABSTRACT Background Amelanotic melanoma (AM) is a subset of melanoma with little to no pigment that can masquerade as a benign condition, and is associated with delayed diagnosis, greater Breslow depth, higher tumour stage, and lower survival than pigmented melanoma.

Expression of CD44 on two lines of transplantable melanoma cells--relationship with cytokine secretion and tumor progression.

Folia Histochemica et Cytobiologica, 2004
In the present work it was investigated if a spontaneous alteration of the native melanotic transplantable melanoma form into amelanotic form, connected with the tumor progression, is accompanied by changes of CD44 surface glycoprotein expression.

Influence of the polyunsaturated fatty acids linoleic acid, arachidonic acid, [alpha]-linolenic acid and [gamma]-linolenic acid on melanogenesis of B16 mouse melanoma cells and normal human melanocytes [PDF]

, 2002
The influence of the polyunsaturated fatty acids (PUFA) linoleic acid, arachidonic acid, α-linolenic acid and γ-linolenic acid on pigmentation was examined using different in vitro models: monolayer cultures of B16 mouse melanoma cells, monolayer ...

Biopsy of Iris and Anterior Chamber Tumours: Fine Needle, Minimally Invasive and Excision Techniques ‐ Review

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Several benign, inflammatory and malignant lesions can present as iris or anterior chamber masses, including iris naevi, cysts, adenomas, leiomyomas, nodules, vascular tumours, melanomas, metastases, as well as iris and pigment epithelium adenocarcinomas. Fortunately, benign iris lesions are much more common than malignant tumours and many can

Primary Anorectal Amelanotic Melanoma: The First Case Report from Saudi Arabia

Middle East Journal of Digestive Diseases, 2019
Anorectal melanomas are exceptionally uncommon and only 30% of anorectal melanomas are amelanotic. We report here a case of an anorectal amelanotic melanoma in a female patient. An 84-year-old patient complained of anal mass for 3 months. On examination,

Age‐related dermatoscopic features of excised melanomas versus nevi in 832 high risk patients

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, EarlyView.
Summary Background and objectives Melanocytic nevi show distinct age‐related dermoscopic patterns. However, data on age‐related patterns of melanomas are lacking. This study aimed to identify age‐related static and dynamic dermoscopic patterns of melanomas. Patients and methods Explorative cross‐sectional cohort study between October 1996 and May 2012,
