Adenomatoid odontogenic tumor (AOT) is an uncommon tumor of odontogenic origin with a relative frequency of 2.2 - 7.1%. As the histogenesis of AOT is still uncertain, it is sometimes categorized as a hamartomatous lesion rather than a true neoplasm. We report a case of AOT in the right maxillary anterior region in a 20-year-old woman. The tumor showed some unusual and aggressive features that s...

Cystic adenomatoid malformation is a rare pulmonary hamartomatous lesion, of an unknown etiology. Report a singular case of CAM of one newborn, with marked respiratory distress. Using different method (chest X-ray, Multidetector row CT associated at multiplanar and three-dimensional reconstructions), we obtained an accurate diagnosis of site and nature, critical for a correct therapeutic approach.

Brunner's gland hamartomas are rare tumours of the duodenum. These lesions have previously been described as being benign, with no malignant potential. A case report is presented of a Brunner's gland hamartoma, whose histology revealed a focus of well marked epithelial dysplasia. This case suggests a dysplastic stage in the natural history of Brunner's gland hamartoma, and questions the maligna...

Adenomatoid odontogenic tumor is a benign, slow growing lesion. It is a relatively uncommon lesion which mainly affects females in their second decade of life, exhibiting predilection for the anterior region of the maxilla. The lesion is usually associated with the crown of an unerupted tooth, most commonly the maxillary canine. We present a case of adenomatoid odontogenic tumor associated with...

HISTOLOGICAL EXAMINATION The round tumour consisted of chondromatous islands separated by loose, partly myxomatous connective tissue with areas containing fat cells, and clefts lined with small cylindrical or cuboid epithelial cells. Cilia were seen in some places on the surface of the epithelial cells. About three-quarters of the tumour consisted of this typical hamartoma-like picture, and the...

Congenital pulmonary airway malformation (CPAM), previously known as congenital cystic adenomatoid malformation (CCAM), is an inborn abnormality of the lower respiratory system. Most often diagnosed in the perinatal period, these anomalies usually present with tachypnea, cyanosis, and respiratory distress. However, rare cases are asymptomatic and undiagnosed until adulthood.

Breast hamartomas are rare, benign, tumor-like nodules composed of glandular, adipose and fibrous tissue. The hamartoma was first described in 1971 as a lipofibroadenoma, fibroadenolipoma or adenolipoma, based on the predominant component of the breast tissue. Clinical findings resemble fibroadenoma and if there is a palpable mass, the patients may receive an immediate diagnosis. Ductal hyperpl...

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...

BACKGROUND Hamartoma of the larynx is a very rare lesion, and the number of reported cases is limited. Signs and symptoms include stridor, changes in voice, eating and respiratory complaints. Stridor is a sign of upper airway obstruction. Patients presenting with stridor and severe respiratory distress necessitate urgent otolaryngologic evaluation. CASE REPORT Herein, we report a case of lary...
