To investigate the diagnosis and surgical treatment of adrenocortical oncocytoma. The clinical data from three cases of adrenocortical oncocytomas (ACOs) were retrospectively analyzed and discussed in light of the relevant literature. In these three cases, one presented with virilization, while the other two cases had no typical clinical features. The tumor was completely encapsulated and was non-invasive. Microscopically, the tumor cells showed neither mitosis nor necrosis, with abundant eosinophilic cytoplasm. No recurrence or metastasis was discovered after close follow-up observation for 12-24 months. Adrenocortical ACOs are rather rare, and most of them are benign. It was hard to make a confirmed diagnosis of ACOs before surgery. Resection of tumor is the best choice, and close follow-up observation is essential.

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.

OBJECTIVETo explore the clinical features and the combined treatment modality of Hurthle cell thyroid tumor (HCT).

METHODSTwenty-eight cases of HCT treated between 2001 and 2009 were analyzed retrospectively.

RESULTSThe age of the patients ranged from 18 to 72 years (with a median of 46.5 years); 22 females and 6 males. The main symptoms were thyroid solitary node or mass (22 cases) and multiple nodule (6 cases), 2 cases with cervical lymph node metastasis. All of the patients underwent surgery, 11 cases with thyroid lobectomy, 11 cases with thyroid lobectomy plus isthmusectomy, 4 cases with subtotal thyroidectomy, and 2 cases with thyroid lobectomy plus isthmusectomy and combined with modified radical cervical lymph node dissection. Postoperative pathological examination showed that 22 cases were Hurthle cell adenomas and 6 cases were Hurthle cell carcinomas, 1 of them with cervical lymph node metastasis. Twenty-one patients with Hurthle cell adenomas were followed up for 6 months to 7.5 years (with a median of 45 months) and 6 patients with Hurthle cell carcinomas for 3 to 8 years (with a median of 54 months), with no recurrence and death case.

CONCLUSIONSHCT is a potential malignant neoplasm. There are some difficulties in the diagnosis of HCT by frozen section. Surgery is an effective treatment for HCT. L-Thyroxine can be used to inhibit TSH excretion.

OBJECTIVESTo investigate the diagnosis, therapy and prognosis of renal oncocytoma.

METHODSThe data of 26 patients of renal oncocytoma in the department of urology of the Peking University First Hospital from 1999 to 2010 were collected. Retrospective analysis of renal oncocytoma clinical characteristics of patients including pathological characteristics and long term follow-up, treatment methods, and prognosis was undergone.

RESULTSThe mean age of these patients was (55 ± 14) years, mean tumor size was (4.1 ± 1.3) cm, corresponding to a mean tumor volume of (24.0 ± 21.1) cm(3). All of these cases were unilocular unilateral. All of these 26 patients received surgical treatment, 5 cases accepted partial nephrectomy while the other cases accepted radical nephrectomy. After a median follow-up time was (47 ± 34) months (range 4 - 144 months) for 25 patients who had been followed up, there was no disease recurrence, progression or death attributed to oncocytoma.

CONCLUSIONSRenal oncocytoma is an uncommon tumor. It exhibits numerous features which are characteristic but not necessarily unique.Preoperative renal mass biopsy is the only way for pre-nephrectomy histologic diagnosis of oncocytoma.

To improve the diagnosis and treatment of renal oncocytoma and avoid unnecessary radical nephrectomy. The clinical data of 6 cases of renal oncocytoma diagnosed at the Second Xiangya Hospital Central South University from March 2005 to November 2010, including symptoms, laboratory tests, imaging, style of operation, pathological examination, and follow-up were retrospectively analyzed.There were no special symptoms and obvious abnormal laboratory tests in the patients. Two patients had relatively special imaging. Partial nephrectomy was performed in 2 cases of renal oncocytoma with typical imaging, while radical nephrectomy was performed on other patients because of misdiagnosis. No relapse and metastasis were found in the following 1 to 5 years.Renal oncocytoma is an uncommon benign tumor. Partial nephrectomy or tumor excision can be performed on patients diagnosed with renal oncocytoma according to typical imaging and intraoperative frozen section biopsy. The final diagnosis depends on pathological examination and regular follow-up is imperative for patients with renal oncocytoma.

OBJECTIVE: To summarize and analyze the clinical data and prognosis of the patients with Hürthle cell tumor (HCT) in order to raise the clinicians' awareness of the disease. METHODS: The clinical data on patients with histopathologically proven HCT, without other thyroid carcinomas, were collected retrospectively in Peking University First Hospital from January 2001 to February 2017. All the patients underwent surgery due to thyroid nodules. The follow-up information was also collected. RESULTS: A total of 100 patients were enrolled in the current study. All of them were diagnosed with Hürthle cell adenoma (HCA). There were 77 females and 23 males, with the male-to-female ratio of 1 : 3.3. The average age of these patients was (52±14) years at the time of operation. Fifty-one patients were found their thyroid nodules accidentally by ultrasonography during their health check-ups. 69.4% of the 49 symptomatic patients presented with painless cervical nodules. 83.0% HCA patients were combined with multinodular goiters (MNGs). 88.4% (76/86) patients were euthyroid and 53.8% (21/39) had increasing thyroglobulin levels. The mean longest diameter of HCAs was (3.2±1.5) cm (range: 0.9-7.3 cm) on ultrasonography. There were a series of sonographic features of HCA, such as larger, solidity, hypoecho, a smooth outline, intranodular vascularization, perinodular vascularization, absence of calcification in nodules and absence of enlarged cervical lymph nodes. Compared with the histological diagnosis, the diagnostic accuracy by frozen section (FS) during operation was 97.4%. Twenty-nine patients were followed up with an average period of (49.2±22.1) months and none of them had local recurrence or cervical lymph node metastasis. Six patients accepted thyroid hormone replacement treatment and one had thyrotoxicosis due to over-dose. CONCLUSION HCA is more common in women. It is often found accidentally by ultrasonography during their health check-ups or presented with painless cervical nodules. It is combined with MNG frequently. HCA exhibits numerous sonographic features but not unique. FS during operation is a reliable method to identify HCA with high diagnostic accuracy. Patients with thyroid hormone administration should be monitored for thyroid function after thyroid surgery.

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.
