This review examines 197 cases of fibrous hamartoma of infancy (FHI) described in the literature and provides a detailed clinicopathologic analysis of what is known to date of this peculiar lesion of the subcutis and lower dermis. The vast majority of these cases occurred within the first year of life ...

According to Gardner's hypothesis (1962) later confirmed by Jannetta (1982, 1985), hemifacial spasm can usually be related to a "vascular conflict" which takes place inside the cerebellopontine angle (CPA). Occasionally, the causative lesion can be identified as a mass encasing the facial nerve at its root exit zone (REZ) from ...

BACKGROUND AND OBJECTIVES: The aim of our study was to review the imaging characteristics, endocrinologic screening and histologic diagnoses of adrenal incidentaloma cases encountered in our institute. METHODS: Thirty-three adrenal incidentaloma cases that had been evaluated in Hacettepe University Hospital between 1985 and 1995 were reviewed retrospectively. Adrenal masses were ...

Sclerosing mesenteritis is an uncommon nonneoplastic inflammatory process in the mesentery that is seen as a pseudotumor, usually involving the small bowel mesentery, the mesenteric fat, and less commonly, the mesentery of the large bowel. We report two cases of sclerosing mesenteritis and review the literature on this rare disease. ...

We report two children with neurofibromatosis type 1 showing enhancing masses on MRI suggesting neoplasms in the chiasm and hypothalamic region. In both patients no visual or endocrinal dysfunction was present. On serial MRI spontaneous partial remission was found, implying that a cautious approach to therapeutic management of similar cases ...

A case of mixed-type liposarcoma, which showed unusual dedifferentiation in the recurrence, is reported. The rapidly growing mass in the palate of a 60-year-old Japanese woman first revealed a combination of myxoid liposarcoma with features resembling storiform malignant fibrous histiocytoma. The recurrent neoplasm, showing an abrupt transition between myxoid and ...

Lymphoma presenting as a soft tissue mass is rare and thus may be confused with the more common soft tissue sarcoma. No previous analysis of the clinical and radiologic features of lymphomas presenting as soft tissue masses is available because most of the cases reviewed are from the pathology literature. ...

An embryonal rhabdomyosarcoma, presenting as a retroperitoneal mass in a 15-year-old girl, is reported. The histological and immunohistochemical picture was typical, except for the presence of focal chondroid differentiation.

We report herein an extremely rare case of intrathoracic omental herniation through the esophageal hiatus. In fact, according to our review of the literature, only eight other cases have been reported, most of which were misdiagnosed as mediastinal lipoma after being identified as an intrathoracic mass. We report herein the ...

Gossypiboma (retained surgical sponge) is a rare but preventable occurrence. In this case it presented as a chronic abdominal mass which simulated a primary small bowel tumour. The findings on pelvic ultrasonography were typical for this condition and the role of plain abdominal radiology in the gynaecological patient are highlighted.

We report an unusual case of an amyloidoma of the gasserian ganglion associated with trigeminal neuralgia. MR imaging showed a mass in Meckel's cave, which was isointense with surrounding tissue on T1-weighted images and hypointense on T2-weighted images. After contrast administration, the mass enhanced homogeneously, and thin cuts through the ...

We describe a case of a 65-year-old Caucasian woman found to have an enlarging mass of the left adrenal gland. Laboratory examination revealed the mass to be nonfunctional. The patient underwent an uneventful left adrenalectomy. Pathological examination revealed the mass to be a leiomyoma. These tumors are benign and develop ...

The case is presented of a coal miner with bilateral masses of progressive massive fibrosis, who developed acute cavitation following fibreoptic bronchoscopy and biopsies. Indeed, immediately upon bronchoscopy with transbronchial biopsy, there was expectoration of abundant melanoptysis. Three days later, the chest radiograph showed a cavity and the patient again ...

The term 'fibromatosis' is used to denote two main pathological entities: juvenile fibromatosis and adult fibromatosis. It is also possible to distinguish between superficial fibromatosis of the aponeurosis and deep fibromatosis of the muscle-aponeurosis. Histopathological findings have indicated that fibromatosis is an invasive neoformation of fibromatous connective tissue involving adjacent ...

We present five cases with gastro (four cases) and intestinal (one case) myogenic tumors with a marked extraluminal growth. In all cases, incidental discovery of an asymptomatic mass prompted further examination. One of three cases with a pedunculated growth mimicked a gallbladder cancer. The mass of a jejunal leiomyoma case ...

A 52-year-old man with a large external nasal mass is presented. Initially, the mass was thought to be rhinophyma, but biopsy of the mass revealed noncaseating granulomata consistent with sarcoidosis. The mass resolved following several steroid injections.
