A 51-year-old woman presented with a rare completely intradural and extramedullary spinal ganglioneuroma associated with multiple hamartoma syndrome and manifesting as complaints of neck pain and dizziness persisting for 8 months. Magnetic resonance imaging of the spinal cord revealed an intradural extramedullary lesion at the C1 level. She underwent right suboccipital craniectomy and C1-2 hemi...

A 65-year-old woman had been followed up for a hamartoma-like mass in the right upper lobe of the lung since 1995. A follow-up CT scan showed an increase in the size of the lesion and a new lesion next to the old mass, which was highly suspected to be lung cancer. A right upper lobectomy was thus performed in May 2000. The hamartoma penetrated the visceral pleura, and adhered to the mediastinal...

To our knowledge, this is the first report of hypogonadotropic hypogonadism, or growth hormone deficiency, in a patient without non-Pallister-Hall syndrome who had hypothalamic hamartoma diagnosed on the basis of MR imaging and MR spectroscopy findings. On short-TE proton MR spectra, the N-acetylaspartate concentration in the hamartoma was lower than that in the thalamus but similar to that in ...

Background: Mucosal Schwann cell hamartoma is a newly recognized disease entity that describes lesions which share some features but are distinct from schwannomas and neurofibromas. This mesenchymal lesion, consisting of a proliferation of Schwann cells in the lamina propria and a strong positivity for the S-100 protein, should be differentiated from other similar lesions because it exists sole...

We report a case of proliferative retinopathy complicated with retinal hamartoma in a tuberous sclerosis patient. This study involved a 16-year-old female patient who was diagnosed as having tuberous sclerosis at birth. Ophthalmic examination revealed retinal hamartoma surrounding the optic disc in both eyes. Vitreous surgery involving a vitrectomy and resection of the proliferative membranes w...

Pulmonary hamartomas are more common than expected because they are usually asymptomatic and are either discovered on routine chest radiography or when they are noted incidentally in approximately 0.25 % of autopsies. In contrast, pulmonary fibroleiomyomatous hamartoma, which consists of interlacing bundles of smooth muscle cells admixed with fibrous tissue and numerous tubular or cleft-like ep...

Neuromuscular and vascular hamartoma has been described as a specific, if rare, stricturing condition of the small intestine. In this paper four cases with very similar macroscopic and histological features to those described as 'neuromuscular and vascular hamartoma' are presented. In three of the patients there was an earlier histologically proven diagnosis of Crohn's disease of the small inte...

A 53 year old man with a large mesenchymal hamartoma is reported. Only a few bile ducts could be found in the periphery of the lesion and no hepatocytes were identified within the lesion. As far as is known, this is the only adult male patient reported to date. On the basis of the reported findings of mesenchymal hamartoma in other adults, it is suggested that there could be changes in the morp...

Brunner's gland hamartoma is a rare benign small bowel neoplasm and most lesions are small and asymptomatic. However, large hamartoma-related obstructive symptoms and hemorrhage related to tumor ulceration manifest as hematemesis or melena. The exact pathogenesis if these lesions is not well known, but they are thought to be frequently associated with Helicobacter pylori infections and chronic ...

splenic tuberculosis is a rare entity, particularly among immunocompetent hosts. hererin, we present a 23 year-old man who was reffered with fever of unknown origin and eventually diagnosed to have splenic tuberculosis with an involvement of a single axillary lymph node as the sole site disease in the other organs.despite two months of treatment with antituberculous agents due to necrotising gr...
