Diagnosis of Basal cell carcinoma
Basal cell carcinoma is the most common form of skin cancer, and it is usually diagnosed through careful clinical evaluation followed by confirmation with tissue examination. It arises from basal-like cells in the epidermis or hair follicles and is strongly linked to cumulative ultraviolet exposure, which causes DNA damage and mutations in pathways such as…

Diagnosis of Atopic dermatitis
Atopic dermatitis is diagnosed primarily through clinical evaluation rather than a single definitive laboratory test. Doctors identify the condition by recognizing a characteristic pattern of chronic or recurrent eczema, typical body-site distribution, and a personal or family background suggestive of allergic disease.

Because these…

Measles is usually diagnosed by combining the patient’s history, the physical findings, and laboratory confirmation. Because the early illness can resemble several other viral infections, clinicians do not rely on the rash alone. Accurate diagnosis matters for two main reasons: measles is highly contagious, and it can cause serious complications such as pneumonia, encephalitis, dehydration,…
