HMGI-C and HMGI(Y) immunoreactivity correlates with cytogenetic abnormalities in lipomas, pulmonary chondroid hamartomas
, endometrial polyps, and uterine leiomyomas and is compatible with rearrangement of the HMGI-C and HMGI(Y) genes.
The diagnosis could be suspected on plain radiograph but MRI is the better diagnostic imaging modality as it can rule out other differential diagnoses such as neurofibromatosis, haemangiomatosis, lymphangiomatosis, Proteus syndrome and fibrolipomatous hamartoma
of the liver in childhood: sonographic and CT findings.
Our case supports the proposed notion that the components and appearance of hamartomas
and diverticula, when present simultaneously in uncommon locations, is a result of malformation attributed to improper proportion and distribution of fetal mesenchymal elements in embryonic development.
, hemangiomas, lymphangiomas, littoral cell angiomas, angiosarcomas, and metastases), and peliosis (2).
Lisch nodules are innocuous iris hamartomas
evident in patients older than 2 years (Fig.

Mascott said he is particularly looking forward to offering his patients image-guided radiosurgery to treat trigeminal neuralgia, vascular malformations and hypothalamic hamartomas
presenting with epilepsy.
are usually congenital anomalies comprising malformations of capillaries; venous, arterial, or lymphatic channels; or various combinations of these.
Shagreen patches are connective tissue hamartomas
that resemble rough orange-peel textured skin patches, and are usually found on the lower back.
Sophia has many hamartomas
(tubers) in her brain and has intractable epilepsy, despite the fact that she has undergone epilepsy surgery twice.
6) On both computed tomography (CT) and magnetic resonance imaging (MRI), biliary hamartomas
are characterized as small cystic lesions, the cystic nature of which may be more readily apparent on MRI; in some cases, uniform or peripheral enhancement of these lesions has been reported.
