Molecular Analysis of Childhood and Adolescent Melanocytic Lesions

Summary

This is an observational, non-therapeutic study to collect clinical and molecular information of pediatric patients with childhood melanocytic lesions. PRIMARY OBJECTIVE: To perform a comprehensive molecular analysis of samples either from paraffin embedded and/or frozen tissue from patients with pediatric melanocytic lesions (including melanoma, spitzoid melanoma, congenital melanoma, melanoma arising in giant nevi). SECONDARY OBJECTIVE: To collect minimal information on patients treated with adjuvant or systemic therapies according to National Comprehensive Cancer Network (NCCN) guidelines.

  * Congenital melanoma
  * Melanoma arising in a giant congenital nevus
  * Melanocytic lesions with indeterminate biological behavior (e.g., pigment synthesizing melanomas)
* Participant was \<19 years of age at the time of diagnosis.
* Tissue is available for biologic studies.
* Participant has been enrolled on the TBANK protocol at SJCRH, or will be enrolled before any research tests are performed on their biological materials.

Exclusion Criteria:

* Ocular melanoma
* Inability or unwillingness of research participant or legal guardian to consent.
* Histologic diagnosis other than melanocytic lesion described in 3.1.1.
