Cutaneous tuberculosis: a practical case report and review for the dermatologist.

Cutaneous tuberculosis occurs rarely, despite a high and increasing prevalence of tuberculosis worldwide. Mycobacterium tuberculosis, Mycobacterrium bovis, and the Bacille Calmette-Guérin vaccine can cause tuberculosis involving the skin. Cutaneous tuberculosis can be acquired exogenously or endogenously and present as a multitude of differing clinical morphologies.

Case-based considerations in the treatment of actinic keratoses: utilizing combination or sequential therapy with 5-fluorouracil cream and destructive treatments.

Dermatologic conditions associated with prolonged sun exposure represent a substantial portion of visits to the dermatologist's office, particularly among elderly populations. Actinic keratoses are premalignant lesions that increase in frequency with each decade of life and have the potential to progress to squamous cell carcinoma. Non-melanoma skin cancers, such as squamous cell carcinoma and basal cell carcinoma, also represent sun-related conditions that require early and aggressive treatment.
