Renal cell carcinoma metastases to pancreas, thyroid, and contralateral adrenal gland are decidedly uncommon. Clear cell renal cell carcinoma (CCRCC) is the most frequent subtype. Cytology diagnosis may be challenging. A 74-year-old male with remote history of vocal cord malignancy and hypertension presented with abdominal pain. Computed tomography (CT) revealed 8.4 cm left renal mass highly suspicious for renal cell carcinoma, a 1.8 cm mass within vessels near left adrenal and a 2.5 cm mass in pancreatic tail...

Diagnosis of cystic papillary thyroid carcinoma (PTC) lymph node metastasis at head neck region can be a challenge in the absence of known PTC history. The congenital cystic lesions of head neck, especially thyroglossal duct cyst (TGDC) and branchial cleft cyst (BCC), are major differential diagnoses in this clinicopathological scenario. The location of cyst and morphology of lining epithelium are critical clues for reaching correct diagnosis. However it is not uncommon that the flattened bland epithelial lining can be seen in both cystic metastases and congenital cystic lesions...

Blunt trauma to the right proximal subclavian artery is uncommon and tends to be associated with pseudoaneurysm formation. We report a patient with right proximal subclavian artery pseudoaneurysm after blunt chest trauma following a motor vehicle accident. The condition was successfully treated with a combined insertion of a covered stent and carotid-carotid bypass as a hybrid procedure. Duplex scans at 6 month and 1 year follow-up documented good stent-graft positioning and no pseudoaneurysm recurrence.

Hyalinizing clear cell carcinoma (HCCC) is a rare salivary gland tumor with a specific EWSR1-ATF1 fusion gene and can have mucin production. Mucoepidermoid carcinoma (MEC) with a clear cell component is its morphologic mimic. Using MAML2 fluorescence in situ hybridization (FISH), a total of 49 MEC cases were separated into MAML2 fusion-positive (32 cases) and MAML2 fusion-negative groups (17 cases). This study used EWSR1 FISH to investigate MAML2 fusion-negative cases to identify previously unrecognized HCCC...

Periprosthetic humerus fractures are relatively uncommon occurrence that can be difficult to manage nonoperatively. Locking plate technology has enhanced the surgical management of these fractures. However, adequate fixation around the stem remains of some concern. We describe an osteosynthesis technique using a locking plate utilizing eccentrically placed screw holes to place "skive screws" in the proximal end of the plate to achieve fixation around the stem of the implant. A clinical series of 5 consecutive patients treated with this technique is presented with an average follow-up of 29 months (range, 12-48)...

Electrically conductive metal-organic frameworks (MOFs) are emerging as a subclass of porous materials that can have a transformative effect on electronic and renewable energy devices. Systematic advances in these materials depend critically on the accurate and reproducible characterization of their electrical properties. This is made difficult by the numerous techniques available for electrical measurements and the dependence of metrics on device architecture and numerous external variables. These challenges, common to all types of electronic materials and devices, are especially acute for porous materials, whose high surface area make them even more susceptible to interactions with contaminants in the environment...

We report the case of a 53-year-old man with solar urticaria (SU) not responding to histamine antagonist therapy. Using intradermal testing with the patient's irradiated serum, we demonstrated that his SU was elicited by visible light only. This type of SU is uncommon, and makes preventive measures such as sun block largely ineffective. However, the patient had an extraordinary response to the treatment with omalizumab. This case report highlights the diagnostic process and the success of omalizumab for the treatment of SU after 16 months of follow-up...

INTRODUCTION: Desmoplastic infantile tumors, especially desmoplastic astrocytomas, are uncommon neoplasms that are generally seen within first 2 years of life. Their occurrence in slightly older children is very rare. The typical radiological appearance is a large cystic lesion with small enhancing solid part. CASE: In the present report, we describe a 10-year-old child with atypical appearance of desmoplastic non-infantile astrocytoma which was predominantly solid on imaging...

Glomus tumors are uncommon tumors that are originated from smooth muscle cells of the neuromioarterials glomus bodies located in the arteriovenous anastomoses subcutaneous tissue or deep dermis of the extremities, mainly in the palms of the hands, wrists and subungual areas of the fingers. Carcinoid tumor, as the glomus tumor, can show an organoid pattern, increased vascularity, and uniform, round cells with eosinophilic cytoplasm, but usually are positive for cytokeratin and always stained with chromogranin and synaptophysin showing negative for smooth muscle markers which is presented in our case...

BACKGROUND: Necrotizing fasciitis is an uncommon, rapidly progressive and potential lethal condition. Over the last decade time to surgery decreased and outcome improved, most likely due to increased awareness and more timely referral. Early recognition is key to improve mortality and morbidity. However, early referral frequently makes it a challenge to recognize this heterogeneous disease in its initial stages. Signs and symptoms might be misleading or absent, while the most prominent skin marks might be in discrepancy with the position of the fascial necrosis...

BACKGROUND: Von Willebrand disease (VWD) is not uncommon in Taiwan. In type 2 or type 3 VWD hemorrhagic symptoms are severer and laboratory data relatively more distinctive. De novo mutation and somatic mosaicism of type 2 VWD gene were rarely reported. Therefore clinical, laboratory and genetic studies of only type 2A, 2B and 2M VWD will be presented and issues of de novo mutation and somatic mosaicism will be explored. METHODS: Fifty-four patients belonging to 23 unrelated families from all around the country in whom type 2 VWD exclusive of type 2N has been diagnosed not only by clinical and routine laboratory studies but also by genetic confirmation during 1990-2015 were investigated...

Kayexalate is an ion exchange resin that is commonly used to acutely treat patients with hyperkalemia. Bowel ulceration and necrosis is a rare and uncommonly recognized complication of kayexalate administration. More often, concomitant administration with sorbitol is reported to damage the bowel; however, there are reports of kayexalate administration causing bowel necrosis without sorbitol. We present a case of a critically ill patient who underwent total colectomy for colonic necrosis secondary to oral kayexalate administration that was not recognized until late in the pathologic process...

Merkel cell carcinoma is a rare primary cutaneous neuroendocrine tumour that is locally aggressive. In most cases the primary treatment is local surgical excision; however, there is a high incidence recurrence both local and distant. Cerebral metastases from Merkel cell carcinoma are extremely uncommon with only 12 cases published in the literature. This case is particularly unusual in that, not only was no established primary lesion identified, but also the patient has survived for 10 years following initial diagnosis and for 9 years following excision of a single brain metastasis...

Delayed sequelae following conservative management of renal trauma in the pediatric population are uncommon. Reports of delayed operations to manage these sequelae are even less common. Here we present the case of a 16-year-old male patient who had delayed development of upper urinary tract obstruction with recurrent infections following high-grade renal trauma managed conservatively. Ultimately he required a robotic-assisted partial nephrectomy two years after initial non-operative management. This is unique as no prior studies to our knowledge have described delayed hydronephrosis and delayed partial nephrectomy over a year following renal trauma...
