Herein reported is a case of congenital malignant melanoma in a premature male baby from a 25-year-old healthy mother who was found to have hydramnios at the 29th week of gestation. The pregnancy was interrupted because of a large posterior neck mass detected by ultrasonography. The large neck mass of the baby was a malignant melanoma involving deep dermis and subcutaneous tissue. The skin over the mass showed a large area of pigmentation with hairs and the pigmentation involved the occipital scalp and posterior neck. Microscopically, the tumor cells were monotonous and showed polygonal and epithelioid appearance with prominent nucleoli indicative of malignant melanoma of a minimal deviation variety. Neither junctional components nor benign dermal nevus cells were noted. There were no distant metastasis or underlying leptomeningeal melanosis. This tumor is presumed to have developed from either preexisted congenital giant pigmented nevus with loss of benign components or de novo origin.

OBJECTIVE: To investigate cervical esophageal reconstruction by means of laryngo-tracheal flap after resection of hypopharyngeal carcinoma with cervical esophageal involvement. METHOD: Eleven cases of hypopharyngeal carcinoma with cervical esophageal involvement. Unilateral piriform sinus and cervical esophagus were involved in 8 cases (8/11) while bilateral piriform sinus, posterior pharyngeal wall and cervical esophagus were involved in 3 cases. After resection of laryngeal, pharyngeal and esophageal tumors and bilateral neck dissection, direct anastomosis of larynx and trachea with esophagus of cervico-thoracic segment was performed if circular structure of larynx and trachea could be preserved (3/11), pectoralis major myocutaneous flap was employed if only part of pharynx and larynx could be preserved (8/11). Postoperative radiochemotherapy was adopted and follow-up lasted for 1-5 years. RESULT: All cases healed without event except for one case of pharyngeal fistula and one case of chylous fistula which also healed after about 2 weeks dressing change. All patients got normal diet without anastomotic stricture. There was no recurrence in 6 patients at the 3 years follow-up, 4 patients had metastases in the neck and 1 patient had thoracic esophageal carcinoma with hepatic metastasis arid gave up further treatment. The overall 3-year survival rate was 54.5%. CONCLUSION Using laryngo-tracheal flap to reconstruct cervical esophagus after resection of hypopharyngeal carcinoma with cervical esophageal involvement is a recommendable method that is simple in processing, reliable in effect and less in postoperative complications.

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.

OBJECTIVE: To evaluate clinical feature, diagnosis, treatment and prognosis of ganglioneuroma in the neck. METHOD: The medical records of 6 patients with cervical ganglioneuroma which were confirmed by pathology between 1995 and 2009 were retrospectively reviewed. RESULT: Patients with ganglioneuroma in the neck typically present with an asymptomatic neck mass. Neither imaging procedures nor fine needle aspiration made a definite diagnosis before surgery. All cases were operated, and developed Horner syndrome. With a median follow-up time of 5.9 years, all cases survived without local recurrence or distant metastasis. CONCLUSION Ganglioneuroma in the neck is a rare well differentiated benign tumour. Definite diagnosis only can be made after pathology. Complete surgical excision is the treatment of choice, as it will ensure thorough sampling of the tumour and cure. Postoperative prognosis is favorable if total resection.

Teratomas comprise the most common extragonadal germ cell tumors in childhood. Most teratomas involving the thyroid are benign and occur in children. However, the adult cases reported are mostly malignant and commonly arise in the thyroid. We report a case of a 31-yr-old female with a huge neck mass. Pathologic examination revealed it to be malignant teratoma composed of primitive neuroepithelial tissue with primitive neural tubes and loose myxoid to fibrous immature mesenchymal stroma. The patient underwent extensive evaluation of the thyroid gland with computed tomography (CT) scan and positron emission tomography (PET) scan, which revealed no evidence of metastatic disease. She underwent total thyroidectomy with bilateral modified radical neck dissection, intensive chemotherapy and radiotherapy. At 22-months of follow-up, the patient has remained euthyroid and showed no evidence of recurrence. This is the first case, to our knowledge, of malignant thyroid teratoma with a exuberant primitive neuroectodermal tumor component in Korea.

BACKGROUND AND OBJECTIVEAmyloid deposition is rare. If there was a great amount of amyloid depositions in the skin tissue, it would be considered to be amyloid deposition disease at first, and then primary cutaneous marginal zone B-cell lymphoma (PCMZL). This study was to analyze the diagnosis and differential diagnosis of two cases of PCMZL with amyloid deposition.

METHODSClinicopathologic characteristics and follow-up of two cases of PCMZL were analyzed. Immunohistochemical staining was performed by EnVision method using antibodies LCA, CD19, CD20, CD79a, CD3, CD7, MUM1, kappa, lambda, Ki-67. IgH and TCRgamma gene rearrangement was detected by polymerase chain reactive (PCR).

RESULTSCase 1, a 71-year-old Chinese male, had a subcutaneous mass on the right elbow that was initially diagnosed with "amyloidosis" in 2004. Three years after the initial diagnosis, he developed recurrences on the right para-auxillary that was still diagnosed with "probably amyloidosis". Four years after the first diagnosis, the patient presented a lesion on the right para-auxillary with a diameter of 2 cm and a lesion on the temporal-parietal dural with a size of 6.0 cmx3.0 cmx3.0 cm. Case 2, a 68-year-old Chinese male, had a subcutaneous mass next to back of the left ear with a size of 9.0 cmx5.0 cm, and he underwent a operation one year previously because of subcutaneous mass in the same site. Microscopically, the tumors of both cases were located in dermis and subcutaneous, tumor cells were medium size with a nodular or diffuse distribution, and some of tumor cells were plasmacytoid/plasma cells. Morphologically, the temporal-parietal dural lesion was similar to subcutaneous lesion and infiltrated into cranial (case 1). Juxtaposed the tumor cells of two cases, there were the large amyloid deposits of amorphous hyaline material and concentrically laminated hyaline spherules in case 1, while cord-like amyloid deposits in case 2. Reactive lymphoid follicles with germinal centers and foreign body giant cells in the stroma were found surrounding the amyloid deposits. Congo red staining showed positive of amyloid deposition in tumor tissues of both cases. Immunohistochemical staining revealed that LCA, CD19, CD20, CD79a and MUM1 expressions were positive in tumor cells, and Ki-67 expression was about 8%-10%. IgL restricted expression as kappa positive while lambda negative was found in both cases. PCR results showed monoclone gene rearrangement of IgH gene in both cases.

CONCLUSIONSOur findings suggest that amyloid deposition rarely present in both primary and metastatic tumors in PCMZL, and its diagnosis should be considered to avoid misdiagnosis. The patients with PCMZL should undergo regular examinations and chemotherapy as well as a long-term follow-up since it is apt to recur or relapse.

PURPOSE: In treating schwannoma patients, it is critical to determine the origin of the tumor to preserve nerve function. We evaluated the validity of preoperative imaging studies in distinguishing the neurological origin of the schwannomas of the head and neck, and the efficacy of intracapsular enucleation in preserving nerve function. MATERIALS AND METHODS: In 7 cases of schwannomas in the head and neck region, we predicted whether the tumor originated from the vagus nerve or the cervical sympathetic chain through imaging studies including computed tomography (CT) and magnetic resonance imaging (MRI). All patients were performed intracapsular enucleation, and the function of the vagus nerve and the sympathetic nerve was evaluated preoperatively and postoperatively. RESULTS: Preoperative imaging studies showed 6 cases where the tumor was located between the carotid artery and the internal jugular vein, and 1 case where the tumor was located posteriorly, displacing the carotid artery and the internal jugular vein anteriorly. At the time of operation, we confirmed schwannoma originating from the vagus nerve on the first 6 cases, and schwannoma originating from the sympathetic nervous system on the last case. All patients went through successful intracapsular enucleation, and of the seven schwannoma cases, 6 patients maintained normal postoperative neurological function (85.7%). CONCLUSION: Preoperative imaging studies offer valuable information regarding the location and origination of the tumor, and intracapsular enucleation helped us to preserve the nerve function.
