On occasion you may see a report from a Pap test or tissue biopsy stating "atypical cells present." This might cause you to worry that this means cancer, but atypical cells aren't necessarily cancerous. Many factors can make normal cells appear atypical, including inflammation and infection.
“Atypical” cells are often encountered on nondiagnostic lung biopsy, and may represent inadequately sampled malignancy, inflammation, or scarring. Lung adenocarcinomas arise from cells of the lower respiratory tract: bronchial cells and pneumocytes.
Atypical adenomatous hyperplasia (AAH) is a very small tumor made up of abnormal (atypical) gland cells that can progress to AIS, and might eventually become adenocarcinoma if not treated.
Mar 25, 2010 · However, some radiation induced changes may persist throughout life and seen in cytologic specimens as dispersed individual atypical cells. Responses to radiation or chemotherapy may be patchy or diffuse and often bilateral, and such atypical cells may be obtained by bronchial washings or lavage.
In other conditions, cells may reveal multinucleation and prominent nucleoli; however, no characteristic virus cytopathic inclusion is present. In difficult case such as scant specimen with rare atypical cells, immunostain of HSV may help to confirm the diagnosis of HSV infection.
Mar 1, 2023 · The biopsy showed rare, atypical cells with dysplasia, and cytology examination of fluid from the bronchoalveolar lavage showed no malignant cells, failing to confirm a diagnosis of cancer. Nearly 2 months after bronchoscopy, she underwent a percutaneous biopsy of one of the smaller peripheral nodules.
