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.
