A 60 years old female patient presented with $8{\times}6\;cm$ sized painless oval mass in the left parietal region. She had left lobectomy of thyroid gland 10 years ago. Cranial CT, MRI, FGD PET-CT showed a solid mass which invaded left parietal bone. After embolization, craniectomy with tumor excision was performed. Histological examination revealed metastatic follicular cancer originated thyroid gland, with vascular and dura invasion. Postoperatively, neck CT showed right thyroid multiple nodules and right level III multiple lymph node enlargement. Thyroid function test was normal, but level of thyroglobulin was high (72ng/ml). So she had right lobectomy of thyroid gland with lymph node dissection under a diagnosis of follicular carcinoma. But histological examination revealed adenomatous hyperplasia and not lymph node metastasis. After operation, she received radioiodine therapy of 150mCi and then the level of thyroglobulin normalized (8.4ng/ml). The patient is under follow-up since she had operation 4 months ago.

Objective: Axillary web syndrome (AWS) is a condition comprising fibrous band-like cords that appear in the axilla of patients after axillary lymph node dissection (ALND) during breast cancer surgery and result in pain and reduced mobility. The cords appearing with AWS are hardened veins or lymphatic vessels. Manual therapy and stretching are recommended for pain control and mobility improvement. Therefore, this study investigated the effect of cytoskeletal manual therapy (CMT), which is a new soft tissue mobilization technique. Design: A case report Methods: A 41-year-old woman with AWS after breast cancer surgery and ALND visited a physical therapy clinic because of shoulder pain, decreased function, and decreased mobility. The cords were palpable and pain occurred 2 weeks after surgery. CMT was performed three times per week for a total of 6 weeks. Her pain intensity, range of motion (ROM), and shoulder function were measured. Results: Measurements were performed after 2 weeks and 6 weeks of CMT and evaluated using the numeric pain rating scale (NPRS). Her pain intensity largely decreased after 2 weeks (4-point score reduction) and after 6 weeks (5-point score reduction) of CMT. After CMT, her full ROM was restored and her shoulder function was improved (7-point score reduction). Conclusions: CMT is effective for pain control, mobility improvement, and functional improvement of patients with AWS.

Purpose: Amelanotic melanoma represents a melanoma with an absence or a small number of melanin pigments and comprises 2% of all melanomas. These melanomas are frequently misdiagnosed, probably because of its nonspecific clinical features and difficulty in diagnosis, resulting in delayed diagnosis and treatment. We report a patient with amelanotic melanoma, who underwent surgical treatment with sentinel lymph node biopsy using gamma probe. Methods: A 32-year-old female was presented with a slowly growing ill-defined, hypopigmented nonerythematous lesion with nail defect on right index finger tip. Preoperative punch biopsy was performed, showing an amelanotic melanoma. Sentinel lymph node biopsy was done using gamma probe(Crystal probe system, CRYSTAL PHOTONICS GmbH, Germany) and confirmed no evidence of regional lymph node metastases. The patient underwent amputation at the proximal interphalangeal joint. Results: Histopathologic findings showed superficial spreading melanoma. There were no melanin pigments in Hematoxylin & Eosin stain but positive immunohistochemical stainings for S-100 protein and Hmb45, which were consistent with amelanotic melanoma. Patient's postoperative course was uneventful without any complication and had no evidence of recurrence of tumor in 6 months follow-up period. Conclusion: Amelanotic melanoma is extremely rare subtype of malignant melanoma with histopathologic findings of atypical melanocytes without melanin pigments. Early detection is crucial since survival is strongly related to tumor thickness and tissue invasion at the time of diagnosis. Wide excision is the treatment of choice and other conjunctive therapy has not been successful.

Purpose: The present study was aimed to examine the usefulness of 18F-FDG PET/CT in the evaluation of cervical lymph node metastasis in patients with oral cancer. Materials and methods: Twenty-two patients who underwent neck dissection to treat oral cancer were subjected for examination. The cervical node metastasis was evaluated by means of clinical examination, CT scan, PET, and histologic examination. By comparing the results of each examination modality with those of histologic examination, it's sensitivity, specificity, positive predictive value, and negative predictive value were determined. Results: The oral cancer was more frequent in males with a ratio of 2.14:1. The sixth decade showed the highest incidence in age distribution with mean of $56{\pm}16$. Histologic findings showed that squamous cell carcinoma was the most common (15 patients), and mucoepidermoid carcinoma (3), malignant melanoma (2), and adenoid cystic carcinoma and ghost cell odontogenic carcinoma (1 each), in order. In most cases, wide surgical excision of the primary cancer and neck dissection was performed, followed by reconstruction with free flaps when necessary. When comparing the results of each examination modality with those of the histologic examination, clinical examination showed sensitivity, specificity, positive predictive value, and negative predictive value at 11%, 85%, 33%, and 58%, respectively. CT scans showed at 67%, 77%, 67%, and 77%, while $^{18}F$-FDG PET/CT at 78%, 77%, 70%, and 83%, respectively. Conclusions: These results suggest that PET is more useful, compared with clinical examination and CT scans, in the evaluation of cervical lymph node metastasis in patients with oral cancer.

Aim: To assess the treatment outcome in patients with malignant skin melanoma and prognostic factors for distant metastases (DM), disease-free survival (DFS) and overall survival (OS). Materials and Methods: A retrospective analysis was conducted on 113 patients with malignant skin melanoma (60 females, 53 males, average age-55 years) who were treated surgically. Primary treatment consisted of local excision. In 12 cases, it was accompanied by lymph node excision. In 93 (82%) cases, radicalization was necessary, which was either local only (19 cases) or accompanied by lymph node surgery/biopsy (74 cases). Possible prognostic factors such as Clark's stage and Breslow's depth of invasion, ulceration, average tumor dimensions, lymph nodes metastases (pN+), gender, tumor location and primary excision margins were considered. Results: In 51 (45%) cases, treatment failure occurred. The 5-year DM rate was 47%, the 5-year DFS was 38%, and the 5-year OS was 56%. In the univariate analysis, the important factors with respect to at least one endpoint included Clark's stage, Breslow's depth of invasion, ulceration, average tumor dimensions, lymph nodes metastases, gender and primary tumor localization. The presence of metastasic nodes was the most important prognostic factor, with a 5-year DM rates of 30% for pN(-) and 76% for pN(+) and a 5-year DFS and OS of 56% and 76% for pN(-) and 13% and 24% for pN(+), respectively. The average tumor dimension was independently significant for DFS and OS, with 5-year rates of 69% and 80% for ${\leq}1cm$, 28% and 53% for 1-2 cm, and 18% and 30% for >2 cm, respectively. Tumor location was also significant for DM and OS, with 5-year rates of 69% vs 33% and 41% vs 66% for trunk vs other locations, respectively. Conclusions: The natural course of a malignant skin melanoma treated radically is disadvantageous, with unsuccessful outcome in nearly half of the cases. Common clinical factors, such as Clark's tumor stage, Breslow's depth of invasion and the presence of metastatic nodes, have high prognostic significance. The size and location of the primary lesion may be considered independent prognostic factors. The most important negative prognostic factor is the presence of metastatic regional lymph nodes. Only one quarter of patients with metastases in lymph nodes survive 5 years from primary surgery.

The poor survival rates of patients with carcinoma of a tongue, despite of modern therapy, is well recognized. One of the most important prognostic factors is status of the cervical lymph nodes. There have been a long-standing debate about the treatment of cervical lymph nodes in early-stage tongue cancer. There are two major treatment opinion. The one is surgical excision of primary tumor with prophylactic neck dissection, simultaneously, and the other is to delay the cervical therapy until cervical lymph node is palpable. Recently we have experienced the early cervical metastasis in three patients who had been diagnosed as a carcinoma of the tongue. They were T1, T2 lesion and no palpable node was found. But histopathologic examination showed the occult metastasis or delayed cervical metastasis was occured. By the review of literature and clinical experience, we could conclude the prophylactic neck dissection offers a better chance for success than therapeutic neck dissection of palpable lymph nodes, in case of oral tongue cancer.

Thyroglossal duct cyst is common midline mass, which is related to hyoid bone and may show signs of inflammation. Carcinoma arising in the thyroglossal duct cyst is rare, occuring in less than 1% of thyroglossal duct cyst. Papillary adenocarcinoma is the most common histologic type(75-85%). The initial treatement of choice is wide excision of the tumor bearing tissue(Sistrunk procedure), resection of associated lymph node alone is enough when they are small and isolated, but a modified neck dissection must be done if regional involvement is more extensive. Its prognosis is excellent(the incidence of regional lymph node metastasis is 7% compare to 89% for papillary cancer of thyroid gland proper).

Sebaceous carcinoma (SC) is a rare tumor, accounting for approximately 0.7% of skin cancers. SC can be classified as ocular SC (OSC) or extraocular SC (EOSC) depending on its location. Because EOSC accompanied by metastases is rare, there is a paucity of data about EOSC accompanied by metastasis. This study presents a case of an aggressive EOSC of the scalp with lymph node metastases. The patient underwent wide local excision of the primary tumor with a 1 cm safety margin and bilateral radical lymph node dissection. However, recurrence was observed 1 month after surgery. Radiation therapy and resection were performed for the recurrent tumor. However, distant metastases to both lungs eventually occurred. Here, we describe a rare recurrent case of EOSC of the scalp with distant organ metastasis with a review of the literature.

Angiofollicular lymph node hyperplasia (AFLNH) with well marginated lymphoid masses, is a rare benign disease of unknown etiology. The majority of the disease develop intrathoracically. Histologically this disease can be divided into the hyaline-vascular and the plasma cell types with the hyaline-vascular type prevailing. The plasma cell variant has been associated with nephrotic syndrome, anemia, growth failure, fever, hyperglobulinemia, peripheral neuropathy, and hypoalbuminemia. Surgical resection is known to be treatment of choice in most cases, and radiotherapy is reserved for advanced, unresectable lesions. We report a complete remission of AFLNH in a case treated by sugical excision followed by irradiation.

Objective: Upper paraaortic lymph node dissection (UPALD) to the infrarenal level is one of the most challenging robotic procedures. Because robotic system has the limitation in robotic arm mobility. This surgical video introduces a novel robotic approach, lower pelvic port placement (LP3), to perform optimally and simultaneously both UPALD and pelvic procedures in gynecologic cancer patients using da Vinci Xi system. Methods: The patient presented with high-grade endometrial cancer. She underwent robotic surgical staging operation. For the setup of the LP3, a line was drown between both anterior superior iliac spines. At 3 cm below this line, another line was drown and four robotic ports were placed on this line. Results: After paraaortic lymph node dissection (PALD) was completed, the boom of robotic system was rotated $180^{\circ}$ to retarget for the pelvic lateral displacement. Robotic ports were placed and docked again. The operation was completed robotically without any complication. Conclusion: The LP3 was feasible for performing simultaneously optimal PALD as well as procedures in pelvic cavity in gynecologic cancer patients. The advantage of LP3 technique is the robotic port placement that affords for multi-quadrant surgery, abdominal and pelvic dissection. The LP3 is facilitated by utilizing advanced technology of Xi system, including the patient clearance function, the rotating boom, and 'port hopping' that allows using every ports for a camera. The LP3 will enable surgeons to extend the surgical indication of robotic surgical system in the gynecologic oncologic field.
