Brunner's gland hamartomas are small benign lesions that are most commonly found in the bulb of the duodenum. They are very uncommon, and most are found incidentally during upper gastrointestinal series or esophagogastroduodenoscopy. The lesions tend to be asymptomatic, but patients may present with symptoms of duodenal obstruction or hemorrhage secondary to ulceration. Histologically, a Brunne...

BACKGROUND Fibrous hamartoma of infancy (FHI) is an infrequent benign proliferation of the soft tissues. Ninety one percent of cases occur during the first year of life. FHI is characterized as a subcutaneous lesion with characteristic morphology with a triphasic organoid growth pattern. CLINICAL CASE We present the case of a 6-month-old male infant with a tumor in the medial plantar region o...

We report prenatal and neonatal neuroimaging findings in a case of oral-facial-digital syndrome type VI (OFDS VI). Prenatal MR imaging at 29 weeks' gestation showed hypoplastic cerebellar vermis and hemispheres, the molar tooth sign, and a hypothalamic hamartoma. Neonatal MR imaging confirmed these findings. The neonate developed breathing abnormalities and exhibited frontal bossing, multiple b...

Differential diagnosis of unilateral nasal mass may be a troublesome question, and also unusual conditions such as glandular hamartoma, consisting in non-neoplastic or inborn malformation, must be considered. We here describe a 78-year-old patient with an unilateral nasal mass, associated to a bilateral naso-sinusal polyposis, which was initially considered to be an inverted papilloma, (on the ...

During the normal development of skin, pluripotential cells give rise to keratinocytes, sebaceus glands, hair follicles, apocrine glands and eccrine glands. A hamartoma, or an abnormal mixture of a tissue’s normal components, results from an error in development, among which some show malignant potential. We report two Chinese cases of giant congenital cutaneous hamartoma, a nevus sebaceus of J...

once the lesion is removed it does not reoccur. In the presented case we have evidence to the contrary. Even though the lesion was removed with an Endopouch, there was obviously a contamination of the pleural space. This might be because of residual material of the hamartoma within the lung tissue or manipulation with the instruments. Parenchyma-sparing wedge resection of is probably the better...

Inflammatory polyps of the nasal turbinates (IPNT) in cats are benign growths that are histologically distinct from feline nasopharyngeal polyps. Most cats with IPNT are presented at less than 1 year of age with sneezing, noisy breathing and epistaxis, but without mucoid or mucopurulent nasal discharge. Histologically, IPNT are characterised by the presence of woven bone as part of the prolifer...

Brunner's gland hamartoma is a rare benign tumour of the duodenum. It was first described by Cruveilhier in 1835. Presently around 200 cases have been reported in literature. No sex predilection is seen. Patients usually present in the fifth to sixth decades of life. They may be clinically silent or may present with variable symptoms and occasionally obstructive symptoms and chronic pancreatiti...

Introduction. Lung hamartomas are the most common benign tumors of the lung. Typically, they are located in the peripheral lung, while an endobronchial localisation is rare. Case Presentation. We present a case with the rare diagnosis of an endobronchial hamartoma as incidental finding in a 69-year-old male, caucasian patient with atrial fibrillation. At first admission, the patient's exertiona...

Solid hamartoma of the pancreas is very rare, and only 3 cases have been reported thus far. A patient underwent pancreaticoduodenectomy due to a mass in the head of the pancreas which was suspected to be a borderline malignant tumor, but the histologic diagnosis turned out to be myoepithelial hamartoma (MEH) or adenomyoma. It was characterized by benign duct and glandular structures surrounded ...
