Intranodal hemorrhagic spindle cell tumor with amianthoid fiber
Definition
Intranodal palisaded myofibroblastoma (IPM) is a benign mesenchymal tumor arising in the lymph node.
Clinical Features
Incidence
IPM is a very rare tumor of the lymph node. About 70 cases of it have been reported in the English literature since 1968.
Age
IPM has been diagnosed across a wide range of ages, from 19 to 84 year old. It has a tendency to occur in the middle-aged (40–55 year old).
Sex
The male-female ratio of affected patients has been reported to be 1.5–2:1. The literature review of 22 cases from 1998 to 2019 (Table 1) revealed a slight male predominance (M:F = 12:10).
Site
Most cases of IPM were reported in the inguinal lymph nodes. Other reported sites include the lymph nodes of the axilla, submandible, neck, and pelvis.
Treatment
Local excision is carried out in most cases.
Outcome
Most reported cases have good outcomes. A local recurrence rate of 6% has been reported by Kandemir et al. (
