Scalp melanoma is rare and often late-discovered because of its unusual position. As a consequence, its prognosis is poorer than melanoma on other body sites and only few clinical reports about its dermoscopic pattern have been published. In this paper, we report three clinical cases of scalp melanoma with photographic documentation and dermoscopic images, in order to improve the early detectio...

About half of all patients with malignant melanoma have cardiac metastases. Histological confirmation antemortem of a secondary malignant melanoma of the heart is difficult. The diagnosis of a secondary melanoma in the right atrium was confirmed by transvenous biopsy in a 46 year old woman who had had a melanoma excised from her right leg two years before.

CONTEXT The diagnosis of primary melanoma is easily confirmed after histological analysis of the lesion, whereas it is rarely diagnosed when the patient even has distant metastases. DESIGN Case report CASE REPORT Malignant melanoma is responsible for about 1% of all deaths caused by cancer in the USA and only 3% of all malignant skin diseases. Malignant melanoma is a rare disease, although ...

Malignant melanoma rarely develops in the paranasal sinuses, and generally has a poor prognosis. However, mucosal melanoma can masquerade both clinically and histopathologically as a benign lesion, rendering accurate early diagnosis difficult. On the other hand, angiofibroma, a benign tumor, is more easily diagnosed than a mucosal melanoma, because the former exhibits specific histopathological...

non-hodgkin lymphoma (nhl) is one of the masquerade syndromes of malignant melanoma that can occur with two main patterns of presentations in the eye: metastatic involvement of uveal tract, and primary involvement of retina. we report ophthalmic, imaging and histopathological findings in the first case diagnosed as primary choroidal nhl without central nervous system or systemic involvement. a ...

A positive family history is used in clinical practice as an indication of increased melanoma risk, yet there are no data on the accuracy of reported family histories of melanoma. The validity of case-reported family history of melanoma was assessed in the course of a family and twin study of melanoma in Queensland, Australia, conducted among the families of 2,118 melanoma cases diagnosed in Qu...

BACKGROUND Subtypes of melanoma, such as mucosal, uveal, and acral, are believed to result in worse prognoses than nonacral cutaneous melanoma. After a diagnosis of distant metastatic disease, however, the overall survival of patients with mucosal, uveal, acral, nonacral cutaneous, and unknown primary melanoma has not been directly compared. MATERIALS AND METHODS We conducted a single-center,...

INTRODUCTION We describe an original case of progressive severe dysphagia caused by a posterior mediastinal metastatic melanoma of unknown origin. To the best of our knowledge, such an event has never been described before in the literature. CASE PRESENTATION A progressive severe dysphagia case is reported induced by a melanoma of unknown origin (metastatic to a posterior mediastinal lymph no...

Patients with malignant melanoma are at an increased risk of developing subsequent primary melanomas and also nonmelanoma cutaneous cancers. Several studies have reported an association between malignant melanoma and breast cancer, bladder cancer, colorectal cancer, neuroectodermal tumours, non-Hodgkin's lymphoma, leukaemia and renal cell carcinoma. We report a case series of patients with a di...

Introduction Cutaneous melanoma represents a very aggressive type of cancer that has one of the fastest growing incidences worldwide, with over 150000 new cases estimated in developing countries in 2010 (Jemal et al 2011). Although it represents only 10% of the total cutaneous malignant tumours, melanoma is responsible for over 90% of the deaths caused by these tumours (Jemal et al 2011). Amela...
