A 53 year old woman presented with a lump in the inner lower quadrant of the left breast. Histological examination of the breast tumour confirmed that the lesion was a mammary hamartoma. Carcinoma with foci of microinvasion was observed in the lobules of the hamartoma concomitant with the intraductal spread of lobular carcinoma. Immunohistochemically, the cancer cells were negative for beta-cat...

The bladder hamartoma is an extremely rare entity. We report on its presence in a 5-year-old boy with Goldenhar syndrome. Most probably, this is the first report of a bladder hamartoma presenting with obstruction of the bladder outlet resulting in urinary retention. The obstructive lesion was resected endoscopically. This proved to be curative for the lesion, since the follow-up voiding cysto-u...

hamartoma of the breast is a rare benign breast lesion which is unfamiliar to most clinicians, although the mammographic features are usually characteristic. hamartomas are composed of ducts, lobules, fat and fibrous tissue. these benign lesions are likely to be increasingly diagnosed because of routine screening and hence clinical awareness is paramount to prevent these lesions from being over...

fibrolipomatous hamartoma of nerve (neural fibrolipoma) is a tumor-like lipomatous process principally involving young persons. the median nerve is most commonly affected. the lesion is characterized by a soft slowly growing mass surrounding and infiltrating major nerves and their branches. it may cause symptoms of compression neuropathy and is associated with macrodactyly in one third of cases...

Sir, Eccrine angiomatous hamartoma (EAH) is a rare benign hamartoma of eccrine glands and blood vessels. It most commonly develops before adulthood as a single, slowgrowing lesion on the extremities. We describe here a case of adult-onset EAH with generalized multiple hairy reddish-brown indurated plaques with a rapidly progressive course. As the lesions showed histopathological findings such a...

We report a case of huge pulmonary hamartoma with atrophied right lower lobe in a 33-year-old female patient. The pulmonary hamartoma was solid, 30 × 16.5 × 14.5 cm in size, which sectioned surface reveals a thick-walled fibrous cyst with multiple yellow nodules protruding into the lumen. The tumour was compressing the right lung and there was no evidence of infiltration into the surrounding st...

Respiratory epithelial adenomatoid (READ) hamartoma is a recently described entity characterized by abnormal glandular formations arising from the epithelium of the nasal cavity. The etiology of the lesion is unclear and may be secondary to either sinonasal inflammation or developmental error. We present a case of a 54-year-old man with a unilateral nasal mass found to be consistent with READ h...

Splenic hamartoma is an uncommon benign tumor. We retrospectively analyzed all patients who underwent splenectomy between May 2000 and June 2006 and four cases of splenic hamartoma were encountered. Three patients presented with mild abdominal pain. Abdominal ultrasonography was the first diagnostic step, which revealed a splenic mass. Doppler ultrasonography, computed tomography, and magnetic ...

We present what is believed to be the first report of heterogeneous carcinoma arising from breast ductal adenoma. A 57-year-old woman presented with a nodule in her right breast. Histological examination of a vacuum-assisted biopsy specimen revealed epithelial tubular proliferation and papillary apocrine epithelium. The myoepithelial cells lining the tubules were confirmed by immunohistochemist...

A 10-year-old female miniature poodle had a mass in its carpal joint of the left forelimb. The tumor was divided into small multiple lobules by delicate connective tissues, and necroses were found in some of the central lobules. In some connective stromal areas, chondroid and osteoid tissues were formed. The tumor cells were similar to the structure of apocrine gland epithelial cells with apica...
