We describe a case of fine needle aspiration cytology of metastatic nasopharyngeal carcinoma in the lymph node of the neck presenting a predominantly spindle cell pattern. A 36 year-old male patient complained of dysesthesia on the right face and a palpable neck mass. Fine needle aspiration was done on the neck mass. Tumor cells were present in syncytial groups or singly with mainly spindle shaped nuclei, vesicular chromatin, thin and regular nuclear membrane, occasional prominent nucleoli and a few fool of cellular cohesiveness. The cytoplasm was scant and pale with ill-defined borders. Mature lymphocytes were present in the background of aspirates and within the tumor cell clusters. Histologically, the tumor of nasopharynx showed several areas of spindle cell pattern. Because the tumor cells showed a predominantly spindle shape with vesicular nuclear chromatin, the differential diagnosis of spindle cell sarcoma or granuloma of epithelioid clils were considered, but the characteristic morphology of the nuclei with vesicular chromatin and prominent nucleoli, and cellular cohesiveness were important in making the diagnosis of nasopharyngeal carcinoma. The possibility of metastatic carcinoma should always be considered in fine needle aspiration cytology of the lymph node in the neck because the incidence of metastatic carcinoma, particularly of the nasopharyngeal carcinoma in the lymph nodes of the neck is relatively high.

Intestinal malrotation is a developmental anomaly resulting from embryologic failure of fixation and rotation of the gut and predisposed to midgut volvulus and small bowel obstruction. Acute midgut volvulus is most often encountered in the newborn period. But older children and adults may have a history of intermittent episodes of partial volvulus presenting with recurrent colicky abdominal pain accompanying bilious vomiting. We experienced a case of intestinal malrotation complicated by midgut volvulus presented with recurrent vomiting and abdominal pain in a 6-year-old boy.

Meckel diverticulum (MD) is one of the most common congenital gastrointestinal anomalies and occurs in 1.2-2% of the general population. MD usually presents with massive painless rectal bleeding, intestinal obstruction or inflammation in children and adults. Suppurative Meckel diverticulitis is uncommon in children. An experience is described of a 3-year-old girl with suppurative inflammation in a tip of MD. She complained of acute colicky abdominal pain, vomiting and periumbilical erythema. Laparoscopic surgery found a relatively long MD with necrotic and fluid-filled cystic end, which was attatched to abdominal wall caused by inflammation. Herein, we report an interesting and unusual case of a suppurative Meckel diverticulitis presenting as periumbilical cellulitis in a child. Because of its varied presentations, MD might always be considered as one of the differential diagonosis.

Hemorrhage due to capillary telangiectasia is rare. We report a case of capillary telangiectasia presenting with repeated cerebellar hemorrhage in a 38-year-old male. To our knowledge this is the first case of repeated cerebellar hemorrhage from the capillary telangiectasia. At the first operation, we removed hematoma only, but rebleeding occurred repeatedly in the same area. Finally, we evacuated the recurrent hematoma and vascular mass of capillary telangiectasia at the second operation under surgical microscope. Based on the findings of this case and a review of the literature, we conclude that capillary telangiectasia can be the cause of the massive repeated hemorrhage.

Bilateral renal obstruction is a rare critical condition, requiring a prompt diagnostic approach and treatment to restore the renal function. The most commonly observed obstructive uropathy in children is congenital malformation, such as posterior urethral valves and bilateral ureteropelvic junction obstruction. Malignant pelvic masses obstructing the ureter are widely reported in adults but are rarely observed in children. The treatment of ureteral obstruction related to pelvic malignancy is a therapeutic challenge with a median survival duration of 3-7 months in adults; however, pediatric patients with pelvic malignancy leading to ureteral obstruction had better outcomes, with a reported 5-year mortality rate of 20%, than the adult patients. Here, we report a rare case of bilateral ureteral obstruction associated with pelvic rhabdomyosarcoma presenting with acute kidney injury treated by ureteral diversion with double J stent, and concommittent emergency hemodialysis, leading to restoration of good renal function. We suggest that bilateral ureteral obstruction should be released as soon as possible using surgical or interventional approach to minimize the obstruction period, and subsequential chemotherapy may contribute to improvement of survival and recovery of renal function.

BACKGROUND: Kawasaki disease (KD) sometimes presents with only fever and cervical lymphadenopathy before other clinical signs materialize. This lymphadenopathy-first-presenting Kawasaki disease (LKD) may be misdiagnosed as bacterial cervical lymphadenitis (BCL). We investigated characteristic imaging and clinical data for factors differentiating LKD from BCL. METHODS: We compared imaging, clinical, and laboratory data of patients with KD and BCL. We included patients admitted to a single tertiary center between January 2015 and July 2018. RESULTS: We evaluated data from 51 patients with LKD, 63 with BCL, and 218 with typical KD. Ultrasound imaging revealed multiple enlarged lymph nodes in both LKD and BCL patients. On the other hand, computed tomography (CT) showed more abscesses in patients with BCL. Patients with LKD were younger and showed higher systemic and hepatobiliary inflammatory markers and pyuria than BCL patients. In multivariable logistic regression, younger age and higher C-reactive protein (CRP) retained independent associations with LKD. A comparison of the echocardiographic findings in LKD and typical KD showed that patients with LKD did not have a higher incidence of coronary artery abnormalities (CAA). CONCLUSIONS: LKD patients tend to have no abscesses on CT and more elevated systemic hepatobiliary inflammatory markers and pyuria compared to BCL patients. The absence of abscess on CT, younger age, and elevated CRP were the most significant variables differentiating LKD from BCL. There was no difference in CAA between LKD and typical KD.

Xanthogranulomatous gastritis (XGG) presenting as a subepithelial tumor (SET) is a very rare entity. We report a case of SET-like XGG diagnosed and treated with endoscopic resection. A 55-year-old female patient was initially referred with a 1.5-cm SET located at the anterior wall of the middle antrum. Endoscopic ultrasound examination revealed submucosal invasion without any perigastric lymph node enlargement. Endoscopic resection was performed for an accurate diagnosis and treatment, and the lesion was diagnosed histopathologically as XGG. At the 18-month follow-up after endoscopic resection, there was no evidence of XGG recurrence. SET-like XGG is very rare and the diagnosis is a preoperative challenge. However, inflammatory tumors should be considered in the differential diagnosis of SET.

Vestibular schwannoma, also known as acoustic neuroma, is a rare benign brainstem tumor surrounding the vestibular division of the 8th cranial nerve. The presenting symptoms are hearing loss, tinnitus, and dizziness. Unabated growth can compress 5th (trigeminal nerve) and 7th (facial nerve) cranial nerve, which can cause nerve dysfunction such as orofacial pain, sensory abnormalities, or trigeminal neuralgia. We report a 51-year-old woman who presented with orofacial dysesthesia on her left side of the face with abnormal findings on 5th cranial nerve and 8th (vestibulocochlear nerve) cranial nerve examination. Brain magnetic resonance imaging scan revealed cerebellopontine angle tumor. She was referred to a neurosurgeon and diagnosed with vestibular schwannoma.

Sparganosis is a parasitic infestation caused by sparganum, a plerocercoid tapeworm larva of the genus Spirometra. Since the first case of human sparganosis reported in 1908, sparganosis has been a global disease, and is common in China, Japan, and Southeast Asian countries. Consumption of raw snakes, frogs, fish, or drinking contaminated beverages are sources of human infections. Human sparganosis usually manifests in subcutaneous fat in areas such as the abdomen, genitourinary tract, and limbs. Breast sparganosis cases are rare, representing less than 2% of total cases of human infections. Complete surgical extraction of the sparganum is the treatment of choice. Because of the rarity of the disease, clinical suspicion is vital to reach the diagnosis of breast sparganosis. Here we report 2 rare cases of breast sparganosis presenting with a painless breast lump, both treated with surgical excision and sparganum extraction.

Umbilical venous catheterization (UVC) is a common practice in intensive neonatal care. However, a malpositioned UVC and its prolonged use may lead to various problems, including mechanical, infectious, and thrombotic complications in various organs such as the liver, lungs, and heart. Congenital chylous ascites is characterized by abnormally high levels of triglycerides in the peritoneal fluid of newborns, which originate from refluxed lymph within the abdominal cavity. Herein, we report a case of an UVC complication presenting as chyloperitoneum simulating congenital chylous ascites in a preterm neonate that resulted from total parenteral nutrition (TPN) extravasation from a malpositioned UVC. Biochemical analysis of intraperitoneal chylous fluid and TPN infusate could help confirm the origin of chyloperitoneum. This case suggests that TPN extravasation from UVC should be considered when chyloperitoneum develops in newborns with an indwelling catheter. UVC positions must also be carefully monitored at regular intervals to recognize associated complications early, particularly in cases with an inevitably malpositioned catheter related to the anatomy of the vessel course.
