Patient Characteristics
Sixty cases of PTGC were found on histopathology during the study
period, with 57 discrete patients. Three patients had recurrent
excisional LN biopsies due to persistent lymphadenopathy, all of whom
received repeated diagnoses of PTGC.
Of the 57 patients, 32 were male (56%) and 25 were female (44%) at
diagnosis. Median age was 11 years at diagnosis (range 1-20 years). The
most common location of involvement were head and neck LNs (n=44),
although some patients were noted to have additional sites of adenopathy
on physical exam prior to LN biopsy. Five patients underwent biopsies of
axillary nodes, and eight patients underwent biopsies of abdominopelvic
nodes, including one patient who had PTGC found in a gastrointestinal
lymph node in the terminal ileum.
