Fine needle aspiration cytology of juvenile hyaline fibromatosis: a case report.

BACKGROUND: Juvenile hyaline fibromatosis (YHF) is a rare inherited disorder characterized by tumorous growth of hyalinized fibrous tissue. No report on cytomorphology of this condition is available in English on MEDLINE. CASE REPORT: A 6-year-old girl had multiple nontender nodules on both ear lobes, nose and scalp. Fine needle aspiration of the nodule on the left ear revealed benign, spindle-shaped cells with an eosinophilic ground substance in the background. The diagnosis of JHF was made following cytologic and histopathologic studies.
CONCLUSION: Fine needle aspiration cytology is reliable for the diagnosis of JHF.
