Balloon cell nevus

Balloon cell nevus (pronunciation: /bəˈluːn sɛl ˈniːvəs/) is a type of melanocytic nevus that is characterized by the presence of large, pale, vacuolated cells, known as balloon cells.

Etymology

The term "balloon cell nevus" is derived from the appearance of the cells in this type of nevus. The cells are large and have a clear, vacuolated cytoplasm, giving them a balloon-like appearance. The term "nevus" is derived from the Latin word for "birthmark" or "mole".

Description

Balloon cell nevus is a benign skin lesion that is usually found on the skin, but can also occur in the mucous membranes. It is a type of melanocytic nevus, which means it is made up of melanocytes, the cells that produce the pigment melanin.

In a balloon cell nevus, the melanocytes are transformed into large, pale, vacuolated cells known as balloon cells. These cells have a clear cytoplasm and a small, peripheral nucleus. The presence of these balloon cells is what distinguishes a balloon cell nevus from other types of melanocytic nevi.
