title: Fibrous hamartoma of infancy: a case report with associated cytogenetic findings.
abstract: A 2-month-old male infant presented with a subcutaneous mass on the left middle finger; the mass had been present since birth. This was treated with local excision, and there has been no recurrence. Histology revealed the typical features of a fibrous hamartoma. Cytogenetic studies revealed a reciprocal translocation, t(2;3)(q31;q21), as the sole abnormality. To our knowledge, this is the first report of the cytogenetic findings in fibrous hamartoma, and it suggests that this lesion represents a benign neoplasm.
