OBJECTIVES To investigate the spectrum of growth rates in melanomas and to identify clinical associations of rapidly growing melanomas. DESIGN Clinical interview, skin examination, and pathology review. SETTING Three tertiary melanoma referral centers and 2 private dermatology practices. PATIENTS A total of 404 consecutive patients with invasive primary cutaneous melanomas. MAIN OUTCOME...
a description of routine ocular conditions which can be viewed readily in the outpatient department, but it does not apply to specialised conditions like ocular tumours, and, as stated in the introduction to this book, the relative infrequence of many of these tumours precludes the average eye surgeon from becoming familiar with them, particularly during the various stages of their development....
One of the joys of epidemiology is the discovery of a new association that has not been previously reported in the literature. In this issue of Cancer Epidemiology, Biomarkers and Prevention (1), Vinceti et a!. purport to have observed just such an association between malignant melanoma and exposure to selenium in drinking water from a municipal water supply in Reggio Emilia, a municipality in ...
Although risk factors for primary cutaneous melanoma are well defined, relatively little is known about predictors for second primary melanoma. Given the rising incidence of this cancer, coupled with improvements in survival, there is a prevalent and growing pool of patients at risk of second primary melanomas. To identify the predictors of second primary melanoma, we followed a cohort of 1,083...
OBJECTIVE To report the different clinical aspects of malignant melanoma and their varieties in Iraqi patients. METHODS We carried out this study in the Department of Dermatology and Venereology, Baghdad Teaching Hospital, Baghdad, Iraq during the period from 1985-2005. Eighteen patients with malignant melanoma were enrolled in this work. The different clinical aspects and histopathological e...
C utaneous malignant melanoma (MM) falls into two main groups, based on aetiology [1–3]. First, a small minority of patients have acral MM, in which the disease occurs on the palms and soles. The incidence of acral MM is similar in people with widely different skin colours (and hence with different amounts of skin melanin), and at different latitudes. The palms and soles have a thick epidermis,...
Xeroderma pigmentosum (XP) is defined by extreme sensitivity to sunlight, resulting in sunburn, pigment changes in the skin and a greatly elevated incidence of skin cancers. It is a rare autosomal recessive disorder and has been found in all continents and racial groups. Estimated incidences vary from 1 in 20, 000 in Japan to 1 in 250, 000 in the USA, and approximately 2.3 per million live birt...
This review of 117 melanomas occurring in 115 patients treated by a single surgeon suggests the appropriateness of the therapeutic decisions to be mentioned based upon tumor behavior, determined by microstaging. Local control of level II lentigo maligna melanoma was achieved, in most instances, by local excision with visibly free margins and primary closure. In most of the other instances of me...
INTRODUCTION The Spanish Mohs Surgery Registry is used to collect data on the use and outcomes of Mohs micrographic surgery (MMS) in Spain. The aim of this study was to describe perioperative and intraoperative data recorded for MMS procedures performed between July 2013 (when the registry started) and January 2016. MATERIAL AND METHODS Prospective cohort study of data from 18 hospitals. The ...
Figure 3 Atypical acquired melanosis, shown by clusters ofabnormal melanocytes in the epithelium, migrating awayfrom the basement membrane. Squamous metaplasia ofthe epithelium, with loss ofgoblet cells, is also seen. Haematoxylin and eosin. Magnifcation x300. We present an unusual case in which conjunctival melanoma was preceded by excision of a lentigo maligna melanoma ofthe ipsilateral lower...
