A 4-month-old kitten was presented with a large mass over the temporal area involving the base of the left ear. Cytological evaluation of a fine-needle aspirate was not diagnostic. Computed tomography was used to determine tumor extent. Surgical resection was performed, which included parts of the orbital rim, masticatory muscles, the complete ear canal, and the pinna. Reconstruction of the ocular muscles was performed, and the skin defect was reconstructed using a single pedicle advancement flap. Despite unilateral facial paralysis, postoperative clinical function was excellent and aesthetics were good. Histological examination revealed the tumor to be a teratoma. After a follow-up period of 3 years, no signs of recurrence were evident. Extragonadal teratomas should be considered in the differential diagnosis when young animals are presented with a growing mass located outside the abdominal cavity. Surgical excision of a mature teratoma can be considered curative.

We describe the case of a 77-year-old woman, presenting with non-specific epigastric pain. Physical examination and subsequent imaging revealed the presence of a large mass in the right liver lobe. This was shown to be a leiomyosarcoma on biopsy histology. Further investigation confirmed this to be a primary hepatic leiomyosarcoma with no evidence of metastases. The patient underwent successful surgical resection. She is currently under imaging follow-up, with no evidence of disease recurrence.

BACKGROUND: IGTS is a rare phenomenon of paradoxical germ cell tumor (GCT) growth during or following treatment despite normalization of tumor markers. We sought to evaluate the frequency, clinical characteristics and outcome of IGTS in patients in 21 North-American and Australian institutions. METHODS: Patients with IGTS diagnosed from 2000-2017 were retrospectively evaluated. RESULTS: Out of 739 GCT diagnoses, IGTS was identified in 33 patients (4.5%). IGTS occurred in 9/191 (4.7%) mixed-malignant GCTs, 4/22 (18.2%) immature teratomas (ITs), 3/472 (0.6%) germinomas/germinomas with mature teratoma, and in 17 secreting non-biopsied tumours. Median age at GCT diagnosis was 10.9 years (range 1.8-19.4). Male gender (84%) and pineal location (88%) predominated. Of 27 patients with elevated markers, median serum AFP and Beta-HCG were 70 ng/mL (range 9.2-932) and 44 IU/L (range 4.2-493), respectively. IGTS occurred at a median time of 2 months (range 0.5-32) from diagnosis, during chemotherapy in 85%, radiation in 3%, and after treatment completion in 12%. Surgical resection was attempted in all, leading to gross total resection in 76%. Most patients (79%) resumed GCT chemotherapy/radiation after surgery. At a median follow-up of 5.3 years (range 0.3-12), all but 2 patients are alive (1 succumbed to progressive disease, 1 to malignant transformation of GCT). CONCLUSION: IGTS occurred in less than 5% of patients with GCT and most commonly after initiation of chemotherapy. IGTS was more common in patients with IT-only on biopsy than with mixed-malignant GCT. Surgical resection is a principal treatment modality. Survival outcomes for patients who developed IGTS are favourable.

Background: Osteoid osteoma (OO) is a rare benign tumor of the spine that involves the posterior elements with 75% tumors involving the neural arch. The common presenting symptoms include back pain, deformity like scoliosis, and rarely radiculopathy. Methods: From 2011 to 2017, we evaluated cases of OO managed by posterior surgical resection while also reviewing the appropriate literature. Results: We assessed five patients (three males and two females) averaging 36.60 years of age diagnosed with spinal OOs. Two involved the lumbar posterior elements, two were thoracic, and one was in the C3 lateral mass. All patients underwent histopathological confirmation of OO. They were managed by posterior surgical resection with/without stabilization. No lesions recurred over the minimum follow-up period of 24 months. Conclusion: Surgical excision is the optimal treatment modality for treating spinal OOs. The five patients in this study demonstrated good functional outcomes without recurrences. Further, the literature confirms that the optimal approach to these tumors is complete surgical excision with/without radiofrequency ablation.

Air Compression

Congenital cervical teratomas are benign but serious germinative cell tumors. The possibility of air compression structures and the risk of invasion of vascular and nervous noble elements are crucial prognostic factors in this kind of tumor. Prenatal diagnosis raises on ultrasound examination precising locoregional consequences of the tumor and surgical possibilities. In the propitious cases, prenatal MRI examination is useful to precise tumor’s limits and cerebral status of the foetus. At birth, coordinate management involving anaesthetists, paediatricians and specialized surgeons decrease morbidity and mortality. The recent observation of a case gave us the opportunity to make a literature review of this exceptional afection. It was a newborn female, aged 25 days allowed for anterior cervical mass evolving since the birth associated with moderate dyspnea. Cervical ultrasound coupled to CT scan had objectified a heterogeneous mass with cystic areas and calcifications. The excision was complete and the histopathological study revealed a mature teratoma. The postoperative course was uneventful, with some food and phonatory transient disorders. Cosmetic outcome at 6 months was excellent. Cervical teratoma is a rare tumor, diagnosed mainly in the neonatal period, which requires a prenatal diagnosis and multidisciplinary early management. The prognosis depends mainly on the presence of neonatal respiratory distress and histological form. There are opportunities sudden worsening respiratory and malignant transformation that justify early surgical excision and prolonged follow-up.

Our patient was a 76-year-old female who has been operated on 2 times in 8 years for pelvic chondrosarcoma. The patient came to our clinic with a large mass in left iliac region which extended into the paravertebral area. Physical examination and preoperative imagining studies revealed a mass at the left iliac area that infiltrated sciatic notch and extended from posterior iliac region towards the anterior side of iliac bone through the sciatic notch and an incisional hernia including descending colon. The mass was also penetrating the abdominal cavity through the hernia. Surgical intervention was planned. Since the tumor infiltrated the sciatic nerve, hemipelvectomy was indicated. Patient refused hemipelvectomy. Therefore, palliative debulking surgery was considered. We treated the case with marginal excision and abdominal wall reconstruction employing prolene and vicryl suture materials in order to prevent a postoperative visceral herniation and local invasion. At the latest follow-up appointment in 2 years, the patient still had no signs of tumor recurrence. This case showed us that an incisional hernia can serve as a pathway for the recurrence invasion of the chondrosarcoma.

Abstract Background and Objectives: Carcinomas derived from myoepithelial cells in head and neck regions (CMCHN) are rare. The aim of this study was to demonstrate the clinical behaviors and treatment outcomes of these tumors.Methods: A retrospective review of fifteen CMCHN cases between 2002 and 2019 in a single institution was performed. Results: All of the fifteen patients (100%) underwent primary surgical resection. Eleven patients (73.3%) received conventional postoperative radiotherapy and four (26.7%) received systemic chemotherapy. Consequently, six patients (40%) had frequently recurrence after surgical resection, and seven patients (46.7%) received second or even third operations. Up to the time of last follow-up, only one patient died and the mean survival time was 15.8 years.Conclusions: Currently, complete surgical excision with or without systemic therapy is preferred, but it has limited efficacy on reducing the risk of recurrence. Thus, more effective systemic therapies are required and the researches on the mechanism of CMCHN recurrence should be encouraged.

Abstract BackgroundMyxoid liposarcoma is well known to have an unusual proclivity for extrapulmonary metastasis. However, cardiac metastasis of myxoid liposarcoma is very rare, even in patients with advanced disease.Case presentationA 40-year-old man was diagnosed with myxoid liposarcoma of the right thigh and treated with wide resection. Two years after the surgery, a low-density area in the left ventricle was found on follow-up chest computed tomography, and was suspected of being metastatic disease. He underwent surgical treatment, and the lesion was pathologically confirmed as metastasis of myxoid liposarcoma. Fifteen months later, he complained of slight dyspnea and developed metastatic disease in the right atrium. He was treated with surgical excision, followed by radiotherapy. Although there was no recurrence in the heart since the second cardiac metastasectomy, multiple metastases occurred in the abdominal cavity, lungs, and muscles. He finally died of the disease two years after the second cardiac metastasectomy.ConclusionWe experienced a case of primary myxoid liposarcoma in the thigh, accompanied by ectopic and metachronous cardiac metastases. Although this condition is rare, we should follow-up patients with myxoid liposarcoma, considering the possibility of cardiac metastasis.

Abstract Background Leiomyosarcoma arising from mesentery is a rare tumor associated with worse prognosis. The tumor arises from smooth muscles in vascular wall. Ileal mesentery is common site of this tumor origin. Case presentation A middle age female was presented with complain of abdominal distension. A mass was palpable on abdominal examination. CT scan showed large mesenteric cyst. 15 × 10 cm large mass excised with associated mesentery and small bowel segment and on histopathology was found, and it was diagnosed as mesenteric leiomyosarcoma. The patient was discharged and referred to oncology for chemotherapy. Conclusion Leiomyosarcoma is a rare disease with grave prognosis. There is a paucity of literature and proper guidelines for its management; however, surgical excision with healthy margins is a mainstay of management. Close follow-up is recommended post-operatively because there are high chances of recurrence and metastasis.

An abdominoscrotal hydrocele (ASH) is an uncommon condition characterized by cystic mass that occupies the scrotum and abdomen. The characteristic aspect is the presence of two hydrocele sacs in the abdominal cavity and the scrotum, and compression of one side causes enlargement of the other side, thereby connecting the two sacs. There are several hypotheses regarding the occurrence of ASH. However, the evidence of the hypotheses is lacking. The patient was a 52-year-old male. During observation of the right inguinoscrotal hydrocele, the patient complained of a palpable mass lesion on the right lower quadrant of the abdomen. Physical examination revealed ASH that occurred with the growth of the inguinoscrotal hydrocele. This was further confirmed by sequential imaging test thereby proposing the verification of cephalad extension of hydrocele. The surgical excision was recommended and inguinal exploration was performed under general anesthesia. No evidence of relapse was observed during the 2-year follow-up period after surgery. The present case proves the cephalad extension of hydrocele among other hypotheses on the etiology of ASH.
