Intranodal palisaded myofibroblastoma of the supraclavicular region in an adolescent with an HDAC2 variant: a case report
Intranodal palisaded myofibroblastoma (IPM) is a rare benign mesenchymal tumor of lymph nodes that most often arises in the inguinal region. We report an 18-year-old woman with an incidentally detected left supraclavicular mass. Imaging showed a well-circumscribed hypervascular lesion, and core biopsy demonstrated a spindle-cell neoplasm for which low-grade malignancy could not be excluded. Complete excision revealed an intranodal spindle-cell proliferation with nuclear palisading, hemorrhage, compressed peripheral …
