A myofibroblastic lesion (also called a myofibroblastic proliferation) is a descriptive term used when a tissue sample contains an increased number of myofibroblasts. Myofibroblasts are specialized cells that share features of fibroblasts (cells that make connective tissue) and muscle cells (cells that can contract). Myofibroblasts normally appear during wound healing and tissue repair, where they …

Adult T-cell leukemia/lymphoma (ATLL) is a rare type of blood cancer that develops from T cells, a type of white blood cell that helps the immune system fight infection and regulate immune responses. When ATLL mainly affects the blood and bone marrow, it behaves like a leukemia. When it grows as a solid mass in …

Squamous intraepithelial lesion is an abnormal growth caused by infection with human papillomavirus (HPV). This condition affects the squamous cells, which are thin, flat cells that line certain areas of the body, including the cervix, vagina, vulva, and anus. Squamous intraepithelial lesion is considered a precancerous disease, meaning it has the potential to develop into …

Poorly differentiated carcinoma is a carcinoma (a cancer that starts in the epithelial cells lining the surfaces of organs) whose cells look very abnormal and no longer resemble the healthy tissue they came from. The word differentiated describes how closely cancer cells still look like normal cells. When a carcinoma is poorly differentiated, the cells …
