Primary tumors of the adrenal cortex are comparatively rare. In the medical literature they are most frequently reported as single case. Because of their infrequent occurence some features of their clinical behavior and pathologic anatomy are not widely known. For this reason the recording of the 7 cases from the Department of Pathology, School of Medicine, Chungnam National University is thought to be worth while. Of the seven tumors, five were associated with primary aldosteronism, one Cushing's syndrome, and the remaing one virilizing syndrome. All were benign. Females were affected more frequently than males. Adrenocortical adenomas tend to be small, weighing less than 42 gm. The tumors associated with primary aldosteronism were composed of zona fasciculata-like cells and "hybrid" cells. The tumor with Cushing's syndrome consisted of zona reticularis-like cells. The tumor with virilizing syndrome consisted of zone reticularis-like cells.

Renal dysplasia results from aberrant histogenesis in metanephric differentiation. It is characterized morphologically by abnormal organization and a persistence of primitive structures, such as cartilage, undifferentiated mesenchyme, and immature tubules. Six cases of renal dysplasia from five children and one adult are reviewed. Five patients were female and one patient was male. The chief complaint was urinary incontinence in four patients, dysuria in one patient, and the sixth patient suffered from vesicoureteral reflux. No evidence of family history of renal dysplasia in any patient was seen. According to Risdon's classification, three cases were hypoplastic dysplasia, one case was dysplasia in a duplex system, one case was dysplasia in a triplex system, and one case was dysplasia with vesicoureteral reflux. The ipsilateral ectopic ureteral orifice was identified in four patients, two of which drained into a Gartner's duct cyst, and the orifice was suggested in one patient. On histologic examination, all cases showed primitive ducts surrounded by concentrically arranged primitive mesenchyme. Nests of metaplastic cartilage were observed within the stroma in three of the six cases.

PURPOSE: To evaluate the incidence and CT findings of the medial depression and bony dehiscence of lamina papyracea as an anatomic variation. MATERIAL AND METHODS: 1472 PNS CTs of the patients with symptoms of chronic sinusitis were retrospectively evaluated. RESULTS: The total incidence of depressed lamina papyracea as an anatomic variation was 3.5%(52/1472) on PNS CT. There was a statistically significant correlation between the increasing age and the incidence of delamina papyracea. Depression of lamina papyracea anterior to the basal lamella were more common those of the posterior depression. Associated findings were herniation of adjacent fatty tissue in all cases and the roedial bowing and hypertrophied configuration of the medial rectus muscle without significant herniation in 19 cases(34%). CONCLUSION: Nontraumatic, asymptomatic depression with bony dehiscence of lamina papyracea as an anatomic variation is not uncommon with the incidence of 3.5%. Recognition of its existence and degree may helpful in avoiding various ocular complication during ethmoid surgery.

Pleomorphic (undifferentated) carcinoma is a rare histologic type of carcinomas of the gallbladder and an atypical carcinoid is thought to be an intermediated type between carcinoid tumor and small cell carcinoma. Dense core "neurosecretory" granules can be found in the above mentioned tumors. We experienced a case of a double tumor of the gallbladder in a 51-year old male patient. Grossly, a large solid mass, about 5.0 cm in diameter, was found in the fundic portion and the neck portion also had a small 1.5 cm-sized polypoid mass. Microscopically, these lesions had features of pleomorphic carcinoma and atypical carcinoid, respectively. Immunohistochemically, they manifested reactivity for neuron specific enolase. Ultrastructural study revealed neurosecretory granules in the cytoplasms of tumor cells of the fundic and neck masses. Although light microscopic features of these tumor masses are quite different, we consider that these tumors represent a spectrum of neuroendocrine differentiation.
