Angiomyomatous hamartoma of a popliteal lymph node: an unusual cause of posterior knee pain
ABSTRACT Angiomyomatous hamartoma is a primary vascular tumor primarily found in the inguinal and femoral lymph nodes characterized by the replacement of nodal tissue by smooth muscle cells and fibrous tissue in sclerotic lymphatic stroma. There has been 1 report of an angiomyomatous hamartoma of a cervical lymph node, and this is the first reported case occurring in an extremity. We present a case of angiomyomatous hamartoma occurring in a single popliteal lymph node.

ABSTRACT: Normal 0 false false false EN-GB X-NONE X-NONE MicrosoftInternetExplorer4 Angiomyomatous hamartoma of the lymph node is a benign vascular disorder of unknown aetiology, first described in 1991. However, to the best of our knowledge, it still remains a rare entity with only 17 cases reported so far. We report a case in an 82 year old male, present a review of literature, and stress the importance of diagnosis of this benign condition which obviates the need for unnecessary and extensive surgical resection.Rare tumors 07/2009; 1(2):e25.

ABSTRACT: Posterior knee pain is a common patient complaint. There are broad differential diagnoses of posterior knee pain ranging from common causes such as injury to the musculotendinous structures to less common causes such as osteochondroma. A precise understanding of knee anatomy, the physical examination, and of the differential diagnosis is needed to accurately evaluate and treat posterior knee pain. This article provides a review of the anatomy and important aspects of the history and physical examination when evaluating posterior knee pain. It concludes by discussing the causes and management of posterior knee pain.Current Reviews in Musculoskeletal Medicine 10/2010; 3(1-4):3-10. DOI:10.1007/s12178-010-9057-4

ABSTRACT: We present a case of angiomyomatous hamartoma (AMH) in the popliteal region of a patient with Klippel-Trenaunay syndrome. A 14-year-old boy with a right popliteal mass and recurrent edema of the right leg was admitted to a local hospital where a diagnosis of Klippel-Trenaunay syndrome was made. Three lymph nodes in the right popliteal fossa were removed. Histopathologic examination showed angiomyomatous hamartomas. Postoperatively, the patient was followed for 6 years. He had occasional mild edema of the right leg, but no signs of inflammation or recurrence of the angiomyomas. Our case is the first reported case of angiomyomatous hamartoma in a patient with Klippel-Trenaunay (KT) syndrome.Fetal and pediatric pathology 05/2011; 30(5):320-4.
