  • Title: Non-hematopoietic cutaneous metastases in children and adolescents: thirty years experience at St. Jude Children's Research Hospital.
    Author: Wesche WA, Khare VK, Chesney TM, Jenkins JJ.
    Journal: J Cutan Pathol; 2000 Nov; 27(10):485-92. PubMed ID: 11100807.
    Abstract:
    BACKGROUND: The spectrum of cutaneous metastasis of non-hematopoietic neoplasms in the pediatric population is not well documented. We report the histologic diversity of this unusual process over a 30-year period at a tertiary care center for pediatric malignancy (St. Jude Children's Research Hospital, Memphis, TN, USA). METHODS: Of 1,971 pathology accessions which included histologic material on skin (1,604 surgical cases and 367 autopsy cases) we found 40 cases (2% of total skin accessions) coded for metastatic non-hematopoietic malignancy. RESULTS: The patients (n=34) ranged in age from 1 month to 20 years (mean=9.8 years) and had a male:female ratio of 1:1. The histologic diagnoses were as follows: rhabdomyosarcoma NOS (6 cases), embryonal rhabdomyosarcoma (4 cases), alveolar rhabdomyosarcoma (4 cases), neuroblastoma (8 cases), osteosarcoma (2 cases), choriocarcinoma (2 cases), peripheral neuroepithelioma or Ewing's sarcoma (2 cases), malignant rhabdoid tumor (1 case), paraganglioma (1 case), nasopharyngeal carcinoma (1 case), sarcoma NOS (1 case), colon adenocarcinoma (1 case), and malignant melanoma (1 case). CONCLUSIONS: Cutaneous or subcutaneous metastasis of non-hematopoietic malignancies in children and adolescents is a rare occurrence but in a high percentage of cases may be the first manifestation of disease. The tumors most likely to metastasize to the skin in children are rhabdomyosarcoma and neuroblastoma and they are more likely than adult malignancies to disseminate to multiple distant sites.
