We have reported a high prevalence of hypothyroidism in the cutaneous melanoma population, suggesting that the pathologic hormonal environment of hypothyroidism promotes melanoma growth. The objective of this study was to test the hypothesis that TSH, which circulates at elevated levels in hypothyroid individuals, stimulates the growth of melanoma cells. Our results show that TSH receptors (TSH...

-Tumour antigen-induced inhibition of leucocyte adherence was modified for use in glass test tubes (Tube LAI assay) for the study of cell-mediated antitumour immunity to human malignant melanoma. Peripheral blood leucocytes (PBL) of 20 out of 25 patients (80%) with active malignant melanoma responded to an extract of malignant melanoma with LAI, whereas only 4.5%o of 475 control subjects showed...

PURPOSE Cutaneous melanoma is a common, aggressive cancer with increasing incidence. The identification of melanoma-specific deregulated genes could provide molecular markers for lymph node staging assays and further insight into melanoma tumorigenesis. EXPERIMENTAL DESIGN Total RNA isolated from 45 primary melanoma, 18 benign skin nevi, and 7 normal skin tissue specimens were analyzed on an ...

Malignant melanoma is a potentially lethal cutaneous malignancy. Melanoma in paediatrics is rare as compared to adult melanoma. The clinicopathological characteristics of paediatric melanoma are different from adult melanoma, and the presence of melanoma mimics which occurs frequently in children (Spitz naevi) resulted in diagnosis uncertainty. We reported a 9-year-old girl who presented with a...

BACKGROUND Melanoma is the major cause of skin cancer death worldwide. Parkinson's disease is a neurodegenerative disorder that is caused by mutation of alpha-synuclein or other genes. Importantly, epidemiological studies have reported co-occurrence of melanoma and Parkinson's disease, suggesting that these two diseases could share common genetic components. METHODOLOGY/PRINCIPAL FINDINGS Rec...

We present the case of a patient with malignant melanoma of the glans penis and urethral meatus, which was found in a 60-year-old man with non-healing ulcerative penile lesion and bilateral clinically palpable inguinal lymphadenopathies at diagnosis. A diagnostic biopsy showed the characteristics of a malignant melanoma. Incisional biopsies from the cutaneous lesions on his glans penis and uret...

Four cases of albinism with haemorrhagic diathesis (Hermansky-Pudlak syndrome) are presented. The cases displayed wide phenotypic variation. Electroretinography was performed on all four patients and was found to be normal. One patient developed a cutaneous malignant melanoma.

Primary malignant melanoma of the oral cavity is a rare neoplasm. The tumors tend to metastasize or locally invade tissue more readily than other malignant tumors in the oral region. The survival of patients with mucosal melanomas is less than for those with cutaneous melanomas. Tumor size and metastases are related to the prognosis of the disease. Early detection, therefore, is important.

Interferons (IFNs) are a family of naturally existing glycoproteins known for their antiviral activity and their ability to influence the behavior of normal and transformed cell types. Type I Interferons include IFN- α and IFN- β . Currently, IFN- α has numerous approved antitumor applications, including malignant melanoma, in which IFN- α has been shown to increase relapse free survival. Moreo...
