Which of the following is likely to be a benign condition found on the tongue?

Lymphangioma is a condition that involves the proliferation of lymphatic vessels and is typically considered benign. It usually appears as a soft, painless swelling and can occur anywhere in the body, including the tongue. While it may cause discomfort or other symptoms depending on its size and location, it does not possess the characteristics of malignancy.

This makes lymphangioma an important consideration when evaluating lesions on the tongue, as it generally does not lead to severe health complications compared to other conditions listed. Factors distinguishing it from malignant conditions include its growth pattern and the absence of aggressive local invasion or metastasis, characteristics that are typically associated with tumors such as malignant melanoma or oral squamous cell carcinoma.

Other conditions, though potentially benign, may have varying implications: oral squamous papilloma is benign but could indicate a viral presence, and fibromatosis can be more aggressive in nature. These aspects make lymphangioma a quintessential example of a benign condition that could be found on the tongue.
