Aim: Presumed congenital simple retinal pigment epithelium hamartoma is a rare benign lesion of the macula that mimics congenital hypertrophy of the retinal pigment epithelium (RPE) and combined hamartoma of the retina and the RPE; newer imaging modalities can help in diagnosis. We report three patients with presumed congenital simple RPE hamartoma, and describe the enhanced-depth imaging optic...

BACKGROUND Undifferentiated embryonal sarcoma of the liver (UESL) is a rare malignant mesenchymal tumor that usually occurs in children and is rarely diagnosed in adults. CASE PRESENTATION Here, we describe the case of a 65-year-old woman who presented with a huge cystic lesion in the liver. Laboratory studies performed on admission showed modest inflammation, poor nutrition, and elevated lev...

Breast hamartoma is an uncommon pathological entity. It is exceedingly rare to find ductal carcinoma in situ or invasive carcinoma within a breast hamartoma. We report one such case treated at our unit.

A patient with multiple cystic hamartomas presented with a pneumothorax and later developed a cystic myxomatous vaginal polyp. This and three of the cysts were resected. She remains well 13 years later. Multiple cystic hamartomas are uncommon and may be misdiagnosed as pulmonary metastases.

BACKGROUND The aim of this study was to provide an overview of the literature on Tailgut cysts (TGCs) arising in the presacral space. MATERIALS AND METHODS We present a new case of presacral TGC and a literature review of English-language studies of presacral TGCs, accessed through the PubMed and Google Scholar databases. Keywords used were presacral or retrorectal tailgut cyst, presacral muc...

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...
