Epiteloidní

Epiteloidní refers to a microscopic appearance of cells that resemble epithelial cells. These cells are typically large, plump, and have abundant, eosinophilic cytoplasm, often with vesicular nuclei. This descriptive term is commonly used in pathology to characterize certain types of tumors and inflammatory infiltrates.

The epiteloid morphology is not specific to any particular tissue type and can be seen in a variety of conditions. For instance, granulomas, which are collections of inflammatory cells, often contain epiteloid histiocytes. These are macrophages that have adopted an epiteloid appearance. Similarly, certain neoplasms, such as some types of carcinoma, sarcoma, and melanoma, can exhibit epiteloid features. The term is useful for pathologists to describe cellular morphology and to help narrow down differential diagnoses.

When cells are described as epiteloid, it implies a certain resemblance to the cells lining surfaces or cavities in the body. This resemblance is based on their shape and cellular characteristics observed under a microscope. The precise meaning and significance of epiteloid cells are always interpreted within the context of the tissue source and the overall pathological picture. It is a descriptive term that aids in communication among medical professionals regarding microscopic findings.
