Mesenchymal hamartoma and hepatoblastoma are common causes of hepatic masses in pediatric population; they have similar radiologic and pathologic features. Herein, we present a case of mesenchymal hamartoma that was preoperatively diagnosed as hepatoblastoma. The mass was completely resected instead of being treated with preoperative chemotherapy. Postoperative pathological evaluation revealed ...

EpiGauss is a method that combines single dipole model with dipole clustering to characterize active brain generators in space and time related to EEG events. EpiGauss was applied to study epileptogenic activity in 4 patients suffering of hypothalamic hamartoma related epilepsy, a rare syndrome with a unique epileptogenic source – the hamartoma lesion – and natural propagation hypothesis – from...

BACKGROUND Brunner's hamartoma is a quite rare neoformation whose origin is not completely clear. METHODS A case of a 69-year-old man with recurrent epigastric pain and an endoscopic finding of a duodenal mass is reported. RESULTS The complete removal of hamartoma can give a complete remission of symptoms. CONCLUSIONS Hamartoma can be only diagnosed by endoscopy and histological exam; its...

When a total of 2488 Turkish patients were taken into consideration, carcinomas with apocrine differentiation accounted for 0.7% of invasive breast carcinomas. The aim of this study was to evaluate clinicopathologic features of this rare type breast carcinoma in Turkish population. To our knowledge, our study has a unique specialty as having broadest group of Turkish patients with apocrine carc...

Primary cutaneous apocrine carcinomas are uncommon malignant neoplasms that can be difficult, if not impossible, to distinguish histologically from metastatic breast carcinomas. We present the case of a 71-year-old man with a 5-year history of extensive ulcerated plaques on the posterior neck and posterior scalp. Biopsy revealed a poorly differentiated infiltrating adenocarcinoma consistent wit...

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...

BACKGROUND Fibrous hamartoma is a key pathologic component of congenital pseudarthrosis of the tibia, a challenging and disabling bone disorder. We investigated the biologic characteristics of fibrous hamartoma cells in order to better understand the pathogenesis of this rare disease. METHODS Fibrous hamartoma tissues were surgically excised at the time of osteosynthesis from seven patients w...

Hamartoma is a rare benign tumor of the spleen. It is often asymptomatic and diagnosed incidentally. In this study, we report the case of a 51-year-old female patient who was admitted to our department for intermittent epigastric pain since the last 6 months and left upper quadrant fullness. She was diagnosed with splenic hamartoma histopathologically after splenectomy. Although splenic hamarto...

invasive apocrine carcinoma (iac) of the breast is a rare subtype of breast malignancy. its incidence is not well known, but it is approximately less than 1% to 4%. for these reasons, there are few reports and little information on the radiologic appearance of iac. furthermore, most of the case reports show malignant features which are similar to invasive ductal carcinoma (idc). we present a ra...
