What condition is suggested by dark spots on the palate?

• A. Melanoma
• B. Kaposi sarcoma
• C. Leukoplakia
• D. Oral lichen planus

Answer: (B)

The presence of dark spots on the palate can suggest a condition such as Kaposi sarcoma, which is a type of cancer that can appear as purplish or dark lesions on the mucosal surfaces, including the oral cavity. This condition is often associated with immunocompromised states, particularly in individuals with HIV/AIDS. The dark spots are typically caused by the proliferation of blood vessels and cancerous cells associated with Kaposi sarcoma, leading to a distinctive appearance that can occur on the palate. While melanoma could also present with dark lesions, it is more commonly recognized as a pigmented lesion on the skin rather than the oral cavity. Leukoplakia is characterized by white patches in the mouth and is generally not associated with dark spots. Oral lichen planus can present as white, lacy lesions, and may include some pigmentation, but it does not typically manifest as dark spots. Thus, Kaposi sarcoma is the most fitting diagnosis for dark spots on the palate due to its characteristic appearance and association with systemic conditions.
