Association between tumor-infiltrating lymphocytes and sentinel lymph node positivity in thin melanoma.

Background: Sentinel lymph node biopsy in thin invasive primary cutaneous melanoma (up to 1mm thick) is a controversial subject. The presence of tumor-infiltrating lymphocytes could be a factor to be considered in the decision to perform this procedure.

Objective: To evaluate the association between the presence of tumor-infiltrating lymphocytes and lymph node metastases caused by thin primary cutaneous melanoma.

Congenital and neonatal lupus erythematosus: two case reports.

Early diagnosis of cutaneous melanoma: an observation in southern Brazil.

Background: The incidence of melanoma cutaneous and the mortalities rates are rising in most countries worldwide.
