Clinical management of primary cutaneous melanomas is based on histopathological staging of the tumour. The aim of this study was to investigate, in a non-selected population in clinical practice, the agreement rate between general pathologists and pathologists experienced in melanoma in terms of the evaluation of histopathological prognostic parameters in cutaneous malignant melanomas, and to ...

DNA ploidy of melanocytic skin tumors from 87 patients (53 primary melanomas, 34 nevi) was determined by flow cytometry from routinely prepared paraffin blocks. Ploidy data correlated strongly with conventional morphological parameters. Only 1 of 34 nevi, but 13 of 53 melanomas were aneuploid. Among the melanomas, none of 21 levels I-III melanomas was aneuploid, but 13 of 32 levels IV and V mel...

Background: Patients with single primary melanomas have an increased risk of developing subsequent melanomas. Second tumors diagnosed within three months the incident lesion are termed “synchronous”, while “asynchronous” outside this window. Objective: Compare tumor distributions and survival characteristics patients synchronous asynchronous second to Methods: Retrospective cohort study. Data w...

BACKGROUND Administration of onabotulinumtoxinA (BoNT-A) to peripheral tissues outside the calvaria reduces the number of days chronic migraine patients experience headache. Because the headache phase of a migraine attack, especially those preceded by aura, is thought to involve activation of meningeal nociceptors by endogenous stimuli such as changes in intracranial pressure (i.e. mechanical) ...

Analysis of cyclic AMP-dependent protein kinase catalytic (C) and regulatory (R) subunits in normal human melanocytes and malignant melanomas demonstrated molar excess of regulatory over catalytic subunit in both cell types. Overall, greater catalytic activity, as a measure of C subunit, and cyclic AMP binding activity, as a measure of R subunit, were detected in metastatic compared to primary ...

The unclear role of cytokeratin (CK) in the progression and diagnostics of malignant melanomas stimulated us to compare the reactivity of three antibodies directed to CK in 109 paraffin-embedded melanomas. By far the majority of melanomas did not express cytokeratin even at the<1% level, only vimentin. In about 6% of melanomas it was possible to find CK expression ranging between 3 and 40% of m...

Mucosal melanomas of the head and neck, as a group, are rapidly lethal neoplasms with site-specific differences in survival. They are preponderantly thick melanomas and as a consequence can present with cervical lymph node metastasis with or without distant spread. Long-term survival is unusual to rare; 5-year survival is poor, and 10-year survival, dismal. Whether this life-consuming nature is...
