Brunner's gland adenoma is a rare tumor of duodenum. Patients are usually aymptomatic and most are discovered incidentally during the upper gastrointestinal (GI) series or esophagogastroduodenoscopy. These lesions are most commonly located in the duodenal bulb and clinical manifestations are variable. In symptomatic patients, the most common manifestations are GI hemorrhage and duodenal obstruction. On histologic examination, Brunner's gland adenoma that causes clinical symptoms is composed of hyperplastic Brunner's glands and contains mostly an admixture of glandular, adipose, and muscular tissues. We report a case of large Brunner's gland adenoma causing upper gastrointestinal hemorrhage in a 47-year-old woman which was successfully removed by endoscopic resection without complications such as bleeding or perforation. Microscopically, it was entirely composed of variable Brunner's glands.

Functioning adrenocortical oncocytomas are extremely rare and most reported patients are 40-60 yr of age. To our knowledge, only 2 cases of functioning adrenocortical oncocytomas have been reported in childhood. We report a case of functioning adrenocortical oncocytoma in a 14-yr-old female child presenting with virilization. She presented with deepening of the voice and excessive hair growth, and elevation of plasma testosterone and dehydroepiandrosterone sulfate. She had an adrenalectomy. The completely resected tumor composed predominantly of oncocytes without atypical mitosis and necrosis. A discussion of this case and a review of the literature on this entity are presented.

〓 Objectives: To analyze the pathological and clinical features of nasal respiratory epithelial adenomatoid hamartoma(REAH), and summarize the diagnostic points, to improve the experience of diagnosis and treatment. Methods:The clinical data of 16 patients with REAH were analyzed retrospectively. The clinical manifestations, pathological features, imaging features, surgical treatment and prognosis were summarized. Results:16 cases of REAH were studied, 10 cases(62.50%) were associated with sinusitis, 1 case(6.25%) was associated with inverted papilloma, 1 case(6.25%) was associated with hemangioma. 5 cases(31.25%) had a history of nasal sinus surgery, including 1 case with 3 times of nasal sinus surgery, 1 case with 2 times of nasal sinus surgery, 3 cases with 1 time of nasal sinus surgery; 10 cases(62.50%) occurred in the bilateral olfactory cleft, 2 cases(12.50%) in the unilateral olfactory cleft, 3 cases(18.75%) in the unilateral middle turbinate, 1 case(6.25%) in the nasopharynx. All 16 patients were pathologically diagnosed as REAH. In the patients with lesions located in bilateral olfactory fissures, symmetrical widening of olfactory fissures and lateral displacement of middle turbinate were observed on preoperative sinus CT. The average width of bilateral olfactory fissures was (9.9±2.70) mm. The ratio of wide to narrow olfactory cleft was 1.21 ± 0.19. There was no significant difference in Lund-Mackay score between the two sides(P>0.05). All patients underwent surgery under general anesthesia and nasal endoscopy. The follow-up period ranged from 1 to 66 months, and no recurrence occurred. Conclusion:Preoperative diagnosis of REAH is facilitated by the combination of clinical manifestations and endoscopic and imaging features. Endoscopic complete resection can achieve a good therapeutic effect.

Here, we report an extremely rare case of acquired nasolacrimal duct obstruction caused by oncocytic carcinoma. A 64-year-old man presented to the hospital complaining of epiphora and left-side nasal obstruction. Ophthalmic and otolaryngology examination revealed a left lacrimal duct obstruction caused by a mass in the left nasal cavity and lacrimal drainage system. The mass was removed and confirmed as an oncocytic carcinoma. Nine months after surgery, without adjuvant radiotherapy, a left orbital mass was observed and the patient underwent reoperation. The mass proved to be recurrent oncocytic carcinoma. The patient underwent adjuvant radiotherapy to eradicate any residual tumor and the patient remains tumor-free one year post-radiotherapy.

The metabolic alterations caused by hyperaldosteronism are being increasingly recognized and have generated considerable interest among the medical fraternity. Hyperaldosteronism is suspected to have a pivotal role in the patho-physiology of congestive cardiac failure where it has been studied extensively. But its effects on calcium metabolism, parathyroid metabolism and renal handling of calcium are less well described. Recent experimental models have shed light into the roles played by previously unknown mechanisms in causing these metabolic alterations. We hereby report a case of primary hyperaldosteronism due to adrenal adenoma (Conn's syndrome) who presented with a myriad of clinical features including symptomatic hypocalcemia, significant weight loss along with uncontrolled hypertension for a prolonged period before eventually detected to have primary hyperaldosteronism. Surgical removal of the causative tumor resulted in prompt disappearance of all the symptoms and signs and regain of lost weight.

OBJECTIVETo clarify the frequency, presentation, associated factors, treatment and outcome of hyponatremia after transphenoidal surgery of pituitary adenomas.
METHODSRetrospectively reviewed the database of 183 patients who underwent transphenoidal surgery of pituitary adenoma between January 1999 and June 2000 in our department.
RESULTS38.8% (71/183) had postoperative hyponatremia. Among them, 59.2% (42/71) appeared on the 4th to 7th day postoperatively. 59.2% (42/71) presented with nausea, vomiting, headache, dizziness, confusion and weakness. Hyponatremia was related to age, tumor size and adenoma type, but not related to sex and degree of resection. Treatment consisted of salt replacement and mild fluid restriction in 4 patients and salt and fluid replacement in 67 patients. Hyponatremia resolved within 16 days in all the patients.
CONCLUSIONSHyponatremia often appeared about 7 days after transsphenoidal surgery of pituitary adenomas, especially in elderly and patients with macroadenomas and huge pituitary adenomas. The principle of treatment was salt and fluid replacement.

BACKGROUND/AIMS: In order to determine the malignant potential of gallbladder adenoma for progression to carcinoma, we evaluated the histopathologic features of adenoma and adenoma-related lesions on cholecystectomized specimens. METHODS: Among 1,847 cholecystectomized specimens, 63 specimens from 26 benign adenomas, 9 carcinomas in situ (CIS), and 28 invasive carcinomas were selected. A pathologist reviewed all specimens and selected benign adenomas, CIS in the adenoma, and adenoma residue in invasive carcinomas. Adenomas and adenoma-related lesions were classified according to morphology (tubular, tubulopapillary, and papillary) and the consisting epithelium (biliary, pyloric metaplasia, and intestinal metaplasia). The age and the size of the benign adenomas and carcinomas in the adenoma were also compared. RESULTS: Adenoma and adenoma-related lesions were found in 34 out (1.8%) of all resected gallbladder. Among 9 CIS and 28 invasive carcinomas, adenoma-related lesions were detected in 7 and 1 case, respectively. All eight carcinomas arising in the adenoma were well-differentiated solitary tumors. The diameters of the carcinomas in the adenoma were, on average, larger than that of the benign adenomas (1.8 cm vs. 0.9 cm, p=0.01). The patients with carcinomas in the adenoma were, on average, older than those with benign adenomas, although the difference was insignificant (57 years vs. 47 years, p=0.09). The morphology and consisting epithelium did not differ between the benign adenomas and carcinomas in the adenoma. The malignant transformation occurred in 23.5% of adenomas. CONCLUSIONS: Gallbladder adenoma is a rare disease, although malignant transformation occurs frequently. Adenoma is a precancerous lesion and the adenoma-carcinoma sequence is one of the gallbladder cancer carcinogenesis.
