| description | Lymphadenopathies are a major cause of consultation in internal medicine, with various causes of diagnosis. Unexplained persistent lymphadenopathy must be biopsied to rule out malignant tumor.
We report the case of a 53-year-old man, with inguinal lymphadenopathy evolving for more than one year. The patient had no associated symptoms and his blood tests were unremarkable. Due to the progression of the adenopathy and its hypermetabolism on PET-CT, an excisional biopsy was performed. Histological analysis revealed an intranodal proliferation of spindle cells with a palisading pattern. β-catenine and smooth muscle actin labelling were positive, leading to the diagnosis of intranodal palisaded myofibroblastoma, a benign tumour.
Intranodal palisaded myofibroblastoma is a rare benign cause of adenopathy, with often inguinal lymph node localization and slow growth and without risk of recurrence after surgical removal. |
