Understanding Abnormal Skin Biopsy Results: Causes & Implications

Abnormal results of a skin biopsy may include:

* Acanthosis: Thickening of the epidermis, the outermost layer of the skin. This can be a sign of various conditions, including eczema, psoriasis, and certain types of cancer.

* Atypia: Abnormal changes in the cells of the epidermis. This can be a sign of precancerous or cancerous conditions.

* Dysplasia: A more severe form of atypia, in which the cells of the epidermis show significant changes in their size, shape, and organization. This is often a sign of precancerous conditions.

* Hyperkeratosis: A thickening of the outermost layer of the epidermis, the stratum corneum. This can be a sign of various conditions, including eczema, psoriasis, and certain types of cancer.

* Parakeratosis: The presence of cells in the stratum corneum that have not fully matured and still contain nuclei. This can be a sign of various conditions, including eczema, psoriasis, and certain types of cancer.

* Spongiosis: A spongy appearance of the epidermis, which is caused by the accumulation of fluid between the cells. This can be a sign of various conditions, including eczema, psoriasis, and certain types of infections.

* Ulceration: A break in the skin that extends into the dermis, the layer of skin below the epidermis. This can be a sign of various conditions, including infections, trauma, and certain types of cancer.

* Vasculitis: Inflammation of the blood vessels in the skin. This can be a sign of various conditions, including autoimmune diseases, infections, and certain types of cancer.

The specific abnormal results of a skin biopsy will depend on the underlying condition. Your doctor will interpret the results of your biopsy and discuss them with you in detail.
