A case of painful ophthalmoplegia with unilateral ocular pain, fixed eyeball to all directions of gaze, and loss of vision is presented. After intensive steroid therapy, conjunctival chemosis subsided markedly, but no improvement was seen in other clinical signs. We took a CT scan of orbit brain and performed nasopharyngeal biopsy and open biopsy through craniectomy. Based on the results of clinical features and findings of the CT scan and tissues, we diagnosed painful ophthalmoplegia secondary to nasopharyngeal carcinoma metastasized to orbital apex and brain.

Objective: To evaluate the indications, safety, feasibility, and surgical technique for patients with head and neck cancers undergoing transoral robotic retropharyngeal lymph node (RPLN) dissection. Methods: The current study enrolled 12 consecutive head and neck cancer patients (seven males and four females) who underwent transoral robotic RPLN dissection with the da Vinci surgical robotic system at the Sun Yat-sen University Cancer Center from May 2019 to July 2020. Seven patients were diagnosed as nasopharyngeal carcinoma with RPLN metastasis after initial treatments, 4 patients were diagnosed as thyroid carcinoma with RPLN metastasis after initial treatments, and one patient was diagnosed as oropharyngeal carcinoma with RPLN metastasis before initial treatments. The operation procedure and duration time, intraoperative blood loss volume and complications, nasogastric feeding tube dependence, tracheostomy dependence, postoperative complications, and hospitalization time were recorded and analyzed. Results: All patients were successfully treated by transoral robotic dissection of the metastatic RPLNs, none of which was converted to open surgery. RPLNs were completely resected in 10 patients, and partly resected in 2 patients (both were nasopharyngeal carcinoma patients). The mean number of RPLN dissected was 1.7. The operation duration time and intraoperative blood loss volume were (191.3±101.1) min and (150.0±86.6) ml, respectively. There was no severe intraoperative complication such as massive haemorrhage or adjacent organ injury during surgery. Nasogastric tube use was required in all patients with (17.1±10.6) days of dependence, while tracheotomy was performed in 8 patients with (11.6±10.7) days of dependence. The postoperative hospitalization stay was (8.5±5.7) days. Postoperative complications occurred in 4 patients, including 2 of retropharyngeal incision and 2 of dysphagia. During a follow-up of (6.5±5.1) months, disease-free progression was observed in all patients, 10 patients were disease-free survival and other 2 patients were survival with tumor burden. Conclusions: The transoral robotic RPLN dissection is safety and feasible. Compared with the traditional open surgical approach, it is less traumatic and safer, has fewer complications and good clinical application potentiality. The indications for transoral robotic RPLN dissection include thyroid carcinoma, oropharyngeal carcinoma, and some selected nasopharyngeal carcinoma and other head and neck cancers. Metastatic RPLNs from some nasopharyngeal carcinoma with incomplete capsule, unclear border and adhesion to the surrounding vessels are not suitable for transoral robotic RPLN dissection.

OBJECTIVETo investigate the clinical features of ischemic stroke in patients with nasopharyngeal carcinoma.

METHODSThe clinical data of the nasopharyngeal carcinoma patients with ischemic stroke treated at the First Affiliated Hospital of Guangxi Medical University between January 2006 and December 2013 were collected.

RESULTSAmong 3 822 patients with nasopharyngeal carcinoma 10 patients suffered from acute ischemic stroke. The 10 patients were males and their age ranged from 39 to 70 years old, with an average age of 51 years. All of the patients were found with squamous cell carcinoma, with metastasis in 7 of them. Among the 10 patients, only 3 patients had with traditional risk factors for ischemic stroke, but no traditional risk factor was found in other 7 patients; 2 patients showed single lesion in brain and 8 patients with two or more lesions due to the blockage of multiple cerebral arteries; 7 patients showed an elevated plasma D-dimer level.

CONCLUSIONIt is suggested that the acute ischemic stroke occurring in the patients with nasopharyngeal carcinoma commonly lacks traditional risk factors, with elevated plasma D-dimer levels and multiple lesions due to involvement of several cerebral arteries.

OBJECTIVE: To explore the eye complication of nasopharyngeal carcinoma (NPC), to analysis the clinical manifestation, CT characteristics and pathological diagnosis of eye complications of NPC and to provide the base for early diagnosis of NPC. METHOD: To retrospectively study of 82 cases eye complications in 562 cases NPC, to study their clinical manifestation, CT characteristics and pathological diagnosis. RESULT: The clinical studies showed that eye complication cases were occurred in 82 cases of 562 NPC cases (14.6%). Thirty-six cases in left and 37 cases in right eye, 9 cases in bilateral eyes. Sixty-five cases came from Guangdong, while the others 17 cases come from 5 provinces. There were 9 kinds of eye manifestation. CT appearances: 40 cases suffered from skull base distracted, 6 cases with orbit involved, 2 cases ( in left eyes) with orbit metastasis, 12 cases with nose-sinus involved, 68 case with parapharyngeal space involved, 49 cases with soft issue in wall of styloid process involved (there were many kind of shows in the same case, so the data were repeated in these cases). CONCLUSION There were multiplicity and complexity in eye complication of NPC. Ophthalmologists should think highly of these cases.

A 68-year-old male patient presented with a week of sudden diplopia. He had been diagnosed with nasopharyngeal cancer 8 months prior and had undergone chemotherapy with radiotherapy. Eight-prism diopter right esotropia in the primary position and a remarkable limitation in abduction in his right eye were observed. Other pupillary disorders and lid drooping were not found. After three weeks, the marginal reflex distance 1 was 3 mm in the right eye and 5 mm in the left eye. The pupil diameter was 2.5 mm in the right eye, and 3 mm in the left eye under room illumination. Under darkened conditions, the pupil diameter was 3.5 mm in the right eye, and 5 mm in the left eye. After topical application of 0.5% apraclonidine, improvement in the right ptosis and reversal pupillary dilatation were observed. On brain magnetic resonance imaging, enhanced lesions on the right cavernous sinus, both sphenoidal sinuses, and skull base suggested the invasion of nasopharyngeal cancer. Lesions on the cavernous sinus need to be considered in cases of abducens nerve palsy and ipsilateral Horner's syndrome.

OBJECTIVETo study the clinicopathologic features of follicular dendritic cell sarcoma (FDCS) and its differential diagnosis.

METHODSTen cases of FDCS were studied by light microscopy, immunohistochemistry and in-situ hybridization. The clinical features and follow-up information were analyzed.

RESULTSAmongst the 10 cases of FDCS studied, the male-to-female ratio was 1:1. The mean age of the patients was 42 years. Six of them were located in cervical and peritoneal lymph nodes and four in extranodal sites (including tonsil, pelvic cavity, tail of pancreas and spleen). Histologically, the tumor cells had whorled, storiform or diffuse growth patterns. They were spindle in shape and contained syncytial eosinophilic cytoplasm, with round or oval nuclei, vesicular chromatin, distinct nucleoli and a variable number of mitotic figures. Multinucleated tumor giant cells and intranuclear pseudoinclusions were occasionally seen. There was a sprinkling of small lymphocytes and neutrophils within the tumor as well as in the perivascular region. Immunohistochemical study showed that the tumor cells were diffusely or focally positive for CD21, CD23, CD35 and D2-40, but negative for LCA, CD20, CD3, CD1a, HMB45 and CK. Some of them showed EMA, CD68 and S-100 reactivity. In-situ hybridization for Epstein-Barr virus-encoded RNA (EBER) showed positive signals in only one case (which was diagnosed as inflammatory pseudotumor-like FDCS). Of the 7 patients with follow-up information available (duration: 2 months to 39 months; mean: 14 months), 2 cases with paraneoplastic pemphigus died of pulmonary infection at 5 and 7 months respectively. The remaining 5 patients were alive and disease-free after surgical excision (+/- chemotherapy and radiotherapy).

CONCLUSIONSFDCS is a rare low to intermediate-grade malignant tumor. Appropriate application of FDC markers, such as CD21, CD35 and D2-40, would be helpful for arriving at a correct diagnosis. Most cases are associated with good prognosis after surgical treatment, with or without chemotherapy and radiotherapy. Patients with paraneoplastic pemphigus carry a less favorable prognosis.
