This specialty focuses on diagnosing skin diseases through microscopic examination of skin biopsy samples. Dermatopathologists work closely with dermatologists to diagnose a wide range of skin diseases, from common problems such as psoriasis and eczema to more complex diseases such as skin cancers (melanoma, basal cell carcinoma) and autoimmune disorders that affect the skin. Their expertise is essential for diagnosing skin infections, genetic diseases, and systemic diseases with skin problems.
