Summary
Intranodal palisaded myofibroblastoma (IPM) is a rare benign tumor. This case highlights IPM in submandibular lymph nodes, with successful surgical removal and no recurrence.
Area of Science:
- Pathology
- Oncology
- Surgical Case Report
Background:
- Intranodal palisaded myofibroblastoma (IPM) is a rare mesenchymal tumor.
- Typically found in inguinal lymph nodes, IPM can also occur in cervical regions.
Observation:
- A 44-year-old female presented with a submandibular mass.
- Cervical ultrasound indicated suspect right submandibular adenomegaly.
Findings:
- Histological examination revealed an encapsulated fusocellular proliferation with nuclear palisading.
- Key features included amianthoid fibers, hemosiderin pigment, and extravasated erythrocytes, confirming IPM diagnosis.
Implications:
- This case expands the known locations of IPM to include the submandibular lymph nodes.
- Complete surgical excision resulted in no recurrence at 5-year follow-up, suggesting a favorable prognosis.

Secondary organs, including lymph nodes, the spleen, and mucosa-associated lymphoid tissue (MALT), work harmoniously to protect us from disease and infection.
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...

Lymph nodes are bean-shaped structures that cluster along the lymphatic vessels in the inguinal, axillary, and cervical regions. Each node is divided into compartments by a capsule that extends trabeculae inward.
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...
