Intranodal palisaded myofibroblastoma: histopatologic and clinical review for clinicians and pathologists
Abstract
Intranodal palisaded myofibroblastoma (IPM) is a kind of mesenchymal tumor with benign behaviour. The origin of this tumor is differentiated smooth muscle cells and myofibroblasts. This is a rare entity and differential diagnosis from malignant tumors is important for clinicians and pathologists. The etiology has not been explained adequately. Age range is between 2nd and 8th decades of the life and it is seen more frequently in males. Inguinal region is the most common localization but has been reported in other localizations including submandibular and retroperitoneal areas. Total excision of the tumor is the treatment in these cases. Recurrence is very rare and there is no report about metastasis. In conclusion IPM is a rare entity and it is commonly misdiagnosed as metastasis. Kaposi Sarcoma and schwannoma are the most common two spindle cell neoplasias. Be aware of this unique entity is important because wrong diagnosis causes dangerous management strategies.
