Lobular carcinoma in situ (LCIS) is an incidental microscopic finding with characteristic cellular morphology and multifocal tissue patterns. The condition is a laboratory diagnosis and refers to unusual cells in the lobules of the breast . [ 1 ]
Molecular pathology is commonly used in diagnosis of cancer and infectious diseases. Techniques are numerous but include quantitative polymerase chain reaction ( qPCR ), multiplex PCR , DNA microarray , in situ hybridization , in situ RNA sequencing, [ 3 ] DNA sequencing , antibody based immunofluorescence tissue assays, molecular profiling of ...
In situ hybridization (ISH) is a type of hybridization that uses a labeled complementary DNA, RNA or modified nucleic acid strand (i.e., a probe) to localize a specific DNA or RNA sequence in a portion or section of tissue or if the tissue is small enough (e.g., plant seeds, Drosophila embryos), in the entire tissue (whole mount ISH), in cells ...
Stage 0 which is in situ disease or Paget's disease of the nipple. Stage 0 is a pre-cancerous or marker condition, either ductal carcinoma in situ (DCIS) or lobular carcinoma in situ (LCIS). Stages 1–3 are within the breast or regional lymph nodes. Stage 4 is a metastatic cancer. Metastatic breast cancer has a less favorable prognosis ...
This technology is still in a developmental stage but, like other lab on a chip methods, it may lead to more portable diagnostic techniques. [28] [29] General process of fluorescent in situ hybridization (FISH) used for bacterial pathogen identification. First, an infected tissue sample is taken from the patient.

Clinically, IHC is used in histopathology for the diagnosis of specific types of cancers based on molecular markers. [ citation needed ] In laboratory science, immunostaining can be used for a variety of applications based on investigating the presence or absence of a protein, its tissue distribution, its sub-cellular localisation, and of ...
Chromogenic in situ hybridization (CISH) is a cytogenetic technique that combines the chromogenic signal detection method of immunohistochemistry (IHC) techniques with in situ hybridization. [ 1 ] [ 2 ] It was developed around the year 2000 as an alternative to fluorescence in situ hybridization (FISH) for detection of HER-2/neu oncogene ...
