In a 49 year old male, a chronic alcoholic with hepatomegaly, a subcapsular nodular lesion was detected in the right lobe of the liver. On fine needle aspiration cytology, hepatocellular carcinoma was considered. Excision of the lesion showed features of nonclassical focal nodular hyperplasia with large cell dysplasia that caused the diagnostic dilemma on cytology.

Abstract Introduction/Objective Nodular fasciitis is a rapidly growing but benign self-limited myofibroblastic/fibroblastic tumor of unknown etiology. It was first described in the literature by Konwaler 1955 and can occur any location. tongue rare entity infancy with only one case reported so far. Accurate diagnosis this crucial to avoid possible misdiagnosis malignancy leading radical resecti...

Focal nodular hyperplasia of the liver in a 3 year old child has been successfully treated by ligation of the hepatic artery branches supplying the lesion. The prominence of the abnormal vasculature in the lesion and its possible aetiological involvement is stressed. Because of the risks of partial hepatectomy, hepatic artery ligation is suggested as the treatment of choice for focal nodular hy...

BACKGROUND Nodular fasciitis is a benign reactive proliferative lesion of fibroblast cells, which can occur throughout the body. However, it has rarely been reported in the breast of an elderly woman. CASE PRESENTATION Our patient was an 88-year-old Asian woman who had noticed a mass in her right breast for 1 month before presentation to our hospital. The mass was elastic-hard and 20 mm in si...

We report a case of symptomatic Rathke's cleft cyst with ossification. CT scans showed curvilinear calcification on the wall of the cyst. MR images revealed a cystic sellar lesion with a nodular solid mass extending to the floor of the third ventricle. This case shows that calcification of the suprasellar cyst does not always suggest craniopharyngioma. Rathke's cysts should be histologically di...

  Peripheral calcifying cystic odontogenic tumor (PCCOT) is a rare odontogenic lesion, which represents about 1% of jaw cysts. Here we report clinicopathologic, radiographic and CT scan images of a new case of recurrent large PCCOT located in mandibular gingiva in a 77-year-old male with history of a nodular mass in the same area, which had been completely excised 3 years ago. In reviewing the...

A 30-year-old woman presented with hepatomegaly and an audible hepatic bruit at 24 weeks gestation. Non-contrast MRI demonstrated an exophytic 12.6 x 7.8 x 12.8 cm mass arising from the right lobe of the liver with a central scar, suggestive of focal nodular hyperplasia (FNH). Conservative management included monthly abdominal ultrasound examinations until the time of delivery, to assess growth...

An 18-month-old male entire Bloodhound dog was presented with a six-week history of progressive inspiratory dyspnoea, stridor, dysphonia and exercise intolerance. CT scan performed elsewhere had revealed the presence of an unencapsulated nodular mass (3x1x5 cm) dorsal to the larynx and first tracheal rings. Laryngoscopy demonstrated the presence of bilateral laryngeal paralysis and distorted la...

Amyloidosis is defined as the presence of extra-cellular deposits of an insoluble fibrillar protein, amyloid. The pulmonary involvement of amyloidosis is usually classified as tracheobronchial, parenchymal nodular, or diffuse alveolar septal. A single nodular lesion can mimic various conditions, including malignancy, pulmonary tuberculosis, and fungal infection. To date, only one case of nodula...

AIMS AND BACKGROUND Because of its high thickness, nodular melanoma often bears a poor prognosis. Thus, an earlier diagnosis of this type of lesion while it is still thin would be an important step in secondary prevention. The principal aim of the present study was to better define the initial clinical features of nodular melanoma to allow an early diagnosis. A secondary aim was to establish th...
