Sentinel lymph node (SLN) biopsy is a procedure for identifying subclinical, microscopic nodal metastasis from a malignant tumor. It is based on the principle that some tumors preferentially spread to a first draining or “sentinel” lymph node before they spread to distant sites.

Aug 1, 2013 · Metastasis. The most frequent sites of local metastasis are the preauricular, parotid, and cervical lymph nodes. If there is evidence of regional metastasis on imaging or physical exam, lymph node dissection should be considered.

Dec 1, 2016 · From a series of 268 eyelid carcinomas, we selected the 21 patients with lymph node metastasis, and we analyzed the patterns of lymphatic spread, approach to treatment and outcomes. The most common histological type of eyelid carcinoma with regional metastasis was sebaceous carcinoma (17/21, 81.0%).

From a series of 268 eyelid carcinomas, we selected the 21 patients with lymph node metastasis, and we analyzed the patterns of lymphatic spread, approach to treatment and outcomes. Results: The most common histological type of eyelid carcinoma with regional metastasis was sebaceous carcinoma (17/21, 81.0%).

To determine the frequency and location of regional lymph node metastasis in patients with squamous cell carcinoma (SCC) of the eyelid and periocular skin. Patterns of distant metastasis were also investigated.

Jul 14, 2020 · Sentinel lymph node biopsy is a promising procedure in patients with eyelid and conjunctival malignancy, and it is useful in identifying sentinel lymph nodes. However, at present, insufficient evidence exists showing that SLNB improves patient outcomes and survival.

Jan 1, 2025 · As many malignancies in the periocular region have the potential to metastasize to the regional lymph nodes, sentinel lymph node biopsy has been evaluated for identification of early microscopic lymph node metastasis in patients with cancers of the eyelid and conjunctiva.

While parotid lymph nodes are considered a common site of metastasis, the data are scarce on the number and frequency of early-stage tumors [5-7]. Here, we report the case of a 72-year-old man with a metachronous metastasis in the parotid gland of a previously resected early-stage sebaceous carcinoma of the eyelid.

A sentinel lymph node is a primary lymph node to which metastatic cancer cells spread from a malignancy. More than 1 sentinel lymph node may exist for a tumor. The concept of SLNB is based on the idea that a predictable pattern of lymph node drainage exists from a tumor to the regional lymph nodes. The first lymph node along the pathway

Understanding lymphatic drainage of the eyelids is important for several reasons. Chiefly, eyelid malignancies may first travel to the lymphatics and the draining areas, the sentinel node may be the site of primary metastasis.
