Melanotic neuroectodermal tumors of infancy (MNTIs) are rare fast-growing tumors with high recurrence rates. These tumors, which originate in the neural crest, commonly occur in the anterior maxilla of children under the age of one. Here, we describe an MNTI case in a two-month-old girl with increasing swelling in the left cheek. MNTI was diagnosed in this case following tomography and biopsy. The patient's histological and immunohistochemical profile indicated a remarkable combination of neural, melanocytic, and epithelial cell differentiation. One year following tumor excision, a follow-up examination revealed that the child exhibited no tumor recurrence. Approximately 260 cases of MNTI have been reported since this type of tumor was first described. In the present case, early diagnosis minimized the difficulties and risks associated with treatment and facilitated an optimal outcome. Despite complete surgical excision, careful followup is recommended. In addition, maxillary functional orthopedics and reconstruction may be necessary in cases of MNTI.

Abstract Schwannomas are rare tumours arising from peripheral nerve sheath. Here, a 44-year-old lady came to our clinic with an asymptomatic progressively-enlarging swelling over her upper back. It was fluctuant, with an absence of pain and tenderness. MRI showed a benign, purely-cystic, superficial-intermuscular, extra-spinal swelling nearby upper thoracic vertebrae. Complete surgical excision proceeded smoothly through a well-defined plane between the swelling and the muscles. It was not attached to any identifiable nerve. A 6.5x5.0x2.5 cm ovoid lesion with a glistening whitish-grey capsule was excised and wound reconstructed in layers. Histopathology showed hypercellular areas with nuclear palisading or oval-shaped Verocay bodies. Only S-100 tested positive amongst the five-antigen immunohistochemistry, thus establishing the diagnosis of a schwannoma. Postoperatively, a one-year follow-up period was uneventful. Schwannomas can surprise clinicians by arising anywhere and with atypical presentations. It needs to be in the differential diagnoses of any asymptomatic slowly-growing lesion.

A retrospective study was performed on 31 dogs with completely excised, grade II, cutaneous mast cell tumors in order to determine recurrence rates and sites. Distant tumor recurrence developed in 22% of dogs, and local tumor recurrence developed in 11% of dogs; however, the vast majority of these animals were incompletely staged initially. Complete surgical excision of grade II mast cell tumors was associated with effective local control in 89% of these dogs. Therefore, adjuvant radiation therapy might not be indicated in the majority of dogs with complete surgical excision.

Background: Myxoma is a rare tumor most frequently discovered in cardiac locations. The present report describes a rare case of extracardiac origin in the femoral vein, initially presenting as leg pain and swelling. Case Presentation: A 40-year-old woman was admitted to our regional hospital with unilateral left leg swelling and pain. She underwent a Duplex scan and CT scan, which revealed a 21 x 25 mm diameter mass in contact with the distal femoral vein, initially diagnosed as a thrombosed sacciform aneurysm. The patient underwent surgical excision of a bulging mass in the vein wall, which was directly closed by running suture. The anatomopathological report concluded with a myxoma. One-year follow-up showed a patent vein without evidence of recurrence of the tumor. Conclusion: Although very rare, peripheral venous myxoma may manifest with common symptoms as leg pain and swelling. Current vascular imaging and complete surgical excision should be performed without delay to allow a precise diagnosis and prevent further complications.

Introduction. Myoepithelioma primarily affects the parotid gland and usually presents as a slow-growing painless lump. The aim of this paper is to report a case of myoepithelioma in the mouth floor. Case outline. A young man noticed a painless increased volume in the left side of the mouth floor region, which after one year of evolution presented as a sessile tumor with normal colored mucosa and the absence of secretion output. Computed tomography with contrast showed an image with slightly heterogeneous density, with well-defined limits. Incisional biopsy was performed under local anesthesia, and pathology examination of the sample revealed a myoepithelial neoplasm. Total excision of the lesion was performed under general anesthesia, and histopathological examination confirmed the diagnosis of the salivary gland myoepithelioma. The patient did not present signs of relapse after a year of follow up. Conclusion. Despite the fact that myoepithelioma originating in the salivary gland are considered rare, especially in the mouth floor, this tumor should be considered in the differential diagnosis of similar lesions. Proper treatment appears to be complete surgical excision and post-operative follow-ups shows should be carried out as long as possible, despite the fact that relapses are extremely rare.

Abstract Introduction The accepted treatment of pilonidal disease still consists of surgical excision with primary wound closure. This treatment has complications such as excessive pain, delayed wound healing, and recurrence. We introduced this technique using a radial laser probe (SiLaCTM, Biolitec, Germany). Previous studies have shown encouraging results with respect to safety, patient satisfaction, and minimal recurrence rates. Method The pilot project was planned with the objectives to assess postoperative complications and reoperation rates. All operations were performed as day case procedures under general anaesthesia. We studied the data of our first 25patients operated with this technique between January 2019 and December 2019 using a prospective database and outpatient clinic follow up. Results The median follow up duration was 13 months. The initial success rate was 64%(16/25), reoperation was required in 32%(8/25) and one patient was lost to follow up. one patient returned with abscess formation in the postoperative period. Conclusions SiLaC is a safe and minimally invasive technique for the destruction of the pilonidal cyst and sinus. The success rate is modest, making this new therapy a minimally invasive option for the majority of the patients with pilonidal disease but it should be offered with caution.

Background. We aimed to assess incidentally discovered hepatocellular carcinoma (iHCC) over time and to compare outcome to preoperatively diagnosed hepatocellular carcinoma (pdHCC) and nontumor liver transplants.Methods.We studied adults transplanted with a follow-up of at least one year. Patients were divided into 3 groups according to diagnosis of hepatocellular carcinoma.Results.Between 1990 and 2010, 887 adults were transplanted. Among them, 121 patients (13.6%) had pdHCC and 32 patients (3.6%) had iHCC; frequency of iHCC decreased markedly over years, in parallel with significant increase in pdHCC. Between 1990 and 1995, 120 patients had liver transplants, 4 (3.3%) of them had iHCC, and only 3 (2.5%) had pdHCC, while in the last 5 years, 263 patients were transplanted, 7 (0.03%) of them had iHCC, and 66 (25.1%) had pdHCC (P<0.001). There was no significant difference between groups regarding patient survival; 5-year survival was 74%, 75.5%, and 77.3% in iHCC, pdHCC, and non-HCC groups, respectively (P=0.702). Patients with iHCC had no recurrences after transplant, while pdHCC patients experienced 17 recurrences (15.3%) (P=0.016).Conclusions.iHCC has significantly decreased despite steady increase in number of transplants for hepatocellular carcinoma. Patients with iHCC had excellent outcomes with no tumor recurrence and survival comparable to pdHCC.

Abstract OBJECTIVE: Meningiomas arising from the petroclival region remain a challenging surgical problem. Because of the substantial risk of neurological morbidity, uniformly pursuing a gross total resection (GTR) to minimize tumor recurrence rates may not be justified. We sought to define optimal resection goals based on risk factors for postoperative neurological morbidity and tumor recurrence rates. METHODS: This series represents our experience with 137 meningiomas arising from the petroclival region resected between June 1993 and October 2002. There were 38 male and 99 female patients with a mean age of 53 years. RESULTS: GTR was achieved in 40% of patients, and near total resection (NTR) was achieved in 40% of patients. One operative death occurred. Twenty-six percent of patients experienced new postoperative cranial nerve deficits, paresis, or ataxia when assessed at a mean follow-up of 8.3 months. The risk of cranial nerve deficits increased with prior resection (P &lt; 0.001), preoperative cranial nerve deficit (P = 0.005), tumor adherence to neurovascular structures (P = 0.046), and fibrous tumor consistency (P = 0.005). The risk of paresis or ataxia increased with prior resection (P = 0.001) and tumor adherence (P = 0.045). Selective NTR rather than GTR in patients with adherent or fibrous tumors significantly reduced the rate of neurological deficits. Radiographic recurrence or progression occurred in 17.6% of patients at a mean follow-up of 29.8 months. Tumor recurrence rates after GTR and NTR did not differ significantly (P = 0.111). CONCLUSION: Intraoperatively defined tumor characteristics played a critical role in identifying the subset of patients with an increased risk of postoperative deficits. By selectively pursuing an NTR rather than a GTR, neurological morbidity was reduced significantly without significantly increasing the rate of tumor recurrence.

Abstract Background:To describe the preliminary suppressive effects of iodine 125 brachytherapy for malignant lacrimal gland tumors after excisionMethods:The study recruit 9 patients with lacrimal gland carcinoma from May 2017 to December 2020. All patients underwent eye sparing surgical tumor resection first and then received iodine 125 interstitial brachytherapy to prevent tumor recurrence. We look over whether tumor recurred or metastasized by detecting the visual function and CT/MRI/PET MRI of every patient.Results1 patient was lost visit. The median follow up period was 29 months of other 8 patients (range, 7 43 months). One patient experienced recurrence two years later but was free from local disease after iodine 125 seeds were implanted one more time. The vision of one female patient was lost due to the seeds moving to the optic nerve. In the remaining 6 patients the vision was no changed, and CT/MRI showed no tumor was recurrencedConclusions:Permanent iodine 125 strip implantation in the orbit can be used as an alternative eye sparing surgery for malignant lacrimal gland tumors after tumor excision. It can control tumor recurrence and maintenance of vision and good cosmesis.
