Which lymph node is primarily involved in carcinoma of the lips?

The primary lymphatic drainage for the lips is notably associated with the submental and submandibular lymph nodes. However, in the case of carcinoma of the lips, the submental lymph nodes are particularly significant due to their direct drainage relationship with the anterior portion of the lower lip and the central part of the chin. When cancer develops in the lips, malignant cells typically spread to the nearest lymph nodes, which include those in the submental region.

The submandibular nodes also play a role in draining lymph from the lips, but they primarily monitor the lateral aspects and anterior part of the oral cavity. In contrast, the submental lymph nodes are more directly linked to the central lower lip and are therefore more likely to be the first to show involvement in lip carcinoma.

Cervical nodes generally refer to a broader category that encompasses various lymph nodes in the neck area, including both submandibular and submental nodes, but they are not the primary nodes related to the initial spread of lip carcinoma specifically.

Occipital nodes are not typically involved in the lymphatic drainage of the lips. They are associated more with the scalp and posterior aspects of the head and neck.

Thus, when considering lymphatic drainage specifically associated with carcinoma of the
