Predictive Nuclear Chromatin Characteristics of Melanoma and Dysplastic Nevi
BACKGROUND The diagnosis of malignant melanoma (MM) is among the diagnostic challenges pathologists encounter on a routine basis. Melanoma may arise in patients with preexisting dysplastic nevi (DN) and it is still the cause of 1.7% of all cancer-related deaths. Melanomas often have overlapping histological features with DN, especially those with severe dysplasia. Nucleotyping for identifying n...
متن کاملDysplastic nevi and melanoma.
Dysplastic nevi are described as being on a continuum between common acquired nevi and melanoma because they are morphologically and biologically intermediate between these 2 entities. Since initially being reported as histologic lesions observed in melanoma-prone families, there has been considerable debate about the definition of dysplastic nevi, the histologic and clinical criteria used to d...
متن کاملEstrogen Receptor Beta Expression in Melanomas Versus Dysplastic Nevi
Dear Editor-in-ChiefMalignant melanoma is a tumor arising from melanocyte; this tumor rarely occurs before puberty, with higher mortality rate in males and better survival rate in female patients affected by metastatic melanoma (1, 2). These facts propose that a relationship and association may exist between estrogens and melanoma. The effects of estrogens are mediated by...
متن کاملMelanocytic nevi with features of Spitz nevi and Clark's/dysplastic nevi ("Spark's" nevi).
BACKGROUND Nevi with cytologic characteristics of Spitz nevus and architectural features of Clark's/dysplastic nevus are not well recognized in the literature. METHODS Twenty-seven nevi with characteristics of Spitz nevus and Clark's/dysplastic nevus are reviewed. RESULTS The patients' mean age was 33 years, and 17/27(63%) patients were female. Lesions were most frequent on the trunk and lo...
متن کاملAre synovial biopsies of diagnostic value?
Synovial tissue is readily accessible by closed needle or arthroscopic biopsy. These techniques provide adequate tissue for most diagnostic requirements. Examination of synovial tissue can assist in the diagnosis of some joint infections, and in several atypical or rare synovial disorders. Histological confirmation is not normally required for diagnosis of the common forms of inflammatory arthr...
