Nestin Expression in Spitzoid Lesions: An Immunohistochemical Characterization With Clinical and Dermoscopic Correlations.

Summary of "Nestin Expression in Spitzoid Lesions: An Immunohistochemical Characterization With Clinical and Dermoscopic Correlations."

Spindle or epithelioid melanocytic (Spitz) nevi usually affect children or adolescents and growth in the face or the lower extremities. Histologically, they may show cytoarchitectural atypia and mitotic figures that could represent diagnostic pitfalls with malignant melanoma. Atypical spitzoid tumors (AST) indicate lesions that microscopically show intermediate characteristics between benign nevi and malignant melanoma. Nestin expression has been evaluated in benign nevi and malignant melanoma, but no studies on its role in Spitz lesion have been elaborated so far. Our results indicate that Nestin could allow to discriminate between AST and malignant spiztoid melanoma; the typical dermoscopic pattern is also associated with benign nevi in contrast to the atypical pattern that accumunates AST and malignant spitzoid melanoma.

Genomic Landscape of Spitzoid Neoplasms Impacting Patient Management.

Spitzoid neoplasms are a distinct group of melanocytic proliferations characterized by epithelioid and/ or spindle shaped melanocytes. Intermediate forms that share features of both benign Spitz nevi ...

Stathmin is a potential therapeutic target but not a prognostic marker in melanoma: an immunohistochemical study of 323 melanocytic lesions.

In several solid tumors, an increased stathmin expression is associated with both poor prognosis and resistance to certain chemotherapy types. However, the data regarding melanocytic lesions are very ...

Correlation of melanoma gene expression score with clinical outcomes on a series of melanocytic lesions.

A 23-gene expression signature was recently developed as an adjunct to histopathology to differentiate melanocytic nevi from melanoma. The current study correlated the gene expression signature scores...

Medical and Biotech [MESH] Definitions

A technique encompassing morphometry, densitometry, neural networks, and expert systems that has numerous clinical and research applications and is particularly useful in anatomic pathology for the study of malignant lesions. The most common current application of image cytometry is for DNA analysis, followed by quantitation of immunohistochemical staining.

Infection of the brain, spinal cord, or perimeningeal structures with the larval forms of the genus TAENIA (primarily T. solium in humans). Lesions formed by the organism are referred to as cysticerci. The infection may be subacute or chronic, and the severity of symptoms depends on the severity of the host immune response and the location and number of lesions. SEIZURES represent the most common clinical manifestation although focal neurologic deficits may occur. (From Joynt, Clinical Neurology, 1998, Ch27, pp46-50)

Rare malignant neoplasm of dendritic LANGERHANS CELLS exhibiting atypical cytology, frequent mitoses, and aggressive clinical behavior. They can be distinguished from other histiocytic and dendritic proliferations by immunohistochemical and ultrastructure studies. Cytologically benign proliferations of Langerhans cells are called LANGERHANS CELL HISTIOCYTOSIS.

A type VI intermediate filament protein expressed mostly in nerve cells where it is associated with the survival, renewal and mitogen-stimulated proliferation of neural progenitor cells.

The genetic constitution of the individual; the characterization of the genes.
