Fibromyxoma represents a rare benign neoplasm that mostly affects the posterior region of the mandible. Here, we report the case of a 46-year-old male with a swelling of the right maxilla. After proper diagnosis, he was treated with enucleation and curettage of the tumor. The defect was filled with a pedicled buccal fat pad flap. The mesenchymal origin from the dental follicle of the fibromyxoma is the most plausible explanation. Radiological examination with MRI, CT, and conventional radiography contributes to the differential diagnosis from other benign tumors, such as the ameloblastoma. Its management is surgical and comprises enucleation and curettage or en bloc resection. Patients must be monitored for at least two years postoperatively in order to diagnose possible recurrence. According to the literature, the maxilla is a rare location of a fibromyxoma and, to our knowledge, our case is the 30th presented case of a fibromyxoma of the maxilla.

A 68-year-old female was operated for a giant dedifferentiated retroperitoneal liposarcoma (RLS) encasing entirely the right kidney. She had an en-bloc resection of the tumor with right nephrectomy. The en-bloc resection should avoid R1 resection margins. Renal conservation is suggested if the kidney is widely displaced and for elderly patient.

Myofibromas are rare, benign tumors of myofibroblasts. Their occurrence in adults, involving bone outside of the head and neck, is especially uncommon. The authors report the case of a 34-year-old woman who presented with left-sided brachialgia. Magnetic resonance imaging identified an expansile soft-tissue lesion of the C6–7 facet joint. En bloc resection via a left posterior midline approach was undertaken. Histopathological analysis confirmed the lesion to be a myofibroma. Brachialgia resolved following surgery and there is no evidence of recurrence at 20 months follow-up. Myofibroma is a rare cause of primary soft-tissue tumor of the spine. Surgical excision remains the mainstay of treatment.

This study aimed to assess the utility of the S-O clip during colorectal endoscopic submucosal dissection (ESD). We conducted a retrospective study on 185 patients who underwent colorectal ESD from January 2015 to January 2020. The patients were divided into two groups: before and after the introduction of the S-O clip. Forty-two patients underwent conventional ESD (CO group) and 29 patients underwent ESD using the S-O clip (SO group). We compared the surgery duration, dissection speed, en bloc resection rate, and complication rate between both groups. Compared with the CO group, the SO group had a significantly shorter surgery duration (70.7 ± 37.9 min vs. 51.2 ± 18.6 min; p = 0.017), a significantly higher dissection speed (15.1 ± 9.0 min vs. 26.3 ± 13.8 min; p < 0.001), a significantly higher en bloc resection rate (80.9% vs. 98.8%; p ≤ 0.001), and a significantly lower perforation rate (4.3% vs. 1.3%). In the right colon, the surgery duration was significantly shorter and the dissection speed was significantly higher in the SO group than in the CO group. Moreover, the rate of en bloc resection improved significantly in the right colon. S-O clip-assisted ESD reduces the procedure time and improves the treatment effects, especially in the right colon.

Minor Salivary Gland Tumour

Myoepithelioma is rare benign neoplasm, usually involves salivary glands and very less often seen in minor salivary glands of nose. Clinically it resembles like other tumour masses and thus posed challenge to clinician and pathologist. It becomes very difficult to diagnose due to its varied presentation and propensity for malignant transformation. We reported a case of a male patient with pink fleshy mass in the left nose with epistaxis and nasal obstruction. Preliminary biopsy and contrast-enhanced CT were done to delineate tumour size and type and then patient underwent endoscopic en-bloc resection. Histopathology and immunohistochemistry were found to be consistent for myoepithelioma. No recurrence was seen during a 6-month follow-up period. Its rarity should be a part of differential diagnosis among nasal tumours. Many of the tumour recurrences are associated with incomplete surgical resection so wide local excision with regular follow-up is essential for this rare entity.

The aim of this study was to test whether a single testicular needle biopsy could provide histological results comparable to en bloc resection histology and whether one biopsy was sufficient to reflect the histology of an entire pair of testicles. Two methods of sample collection were tested on 32 bull calves aged five to eight months to compare histological parameters of needle biopsy with those of en bloc resection samples. One testicular needle biopsy of the right and three en bloc samples of both testicles were collected and compared for the number of tubular cross sections, tubules with elongated spermatids (ES), outer/inner diameter of tubules, thickness of tubular wall, and number of Sertoli cells (SC). Additionally, animal data were considered. No significant differences were found between the left and right testis or among the individual locations of en bloc samples. However, histologically significant differences (Bonferroni-adjusted significance level: p < 0.05/6 = 0.0083) were found between the needle biopsy and en bloc resection regarding the tubular cross sections per visual field (p < 0.05), the outer (p = 0.01) and inner diameter and the thickness of the tubular wall (both p < 0.01). In the SOX9 immunohistochemical staining, no significant differences (p > 0.05) could be observed for SC numbers between needle biopsy and en bloc samples. In conclusion, results of testicular needle biopsy do not have the same validity as the en bloc resection histology. Furthermore, one biopsy is insufficient to reflect the histology of the entire testicular pair.

Chordomas are histologically benign tumors with local aggressive behavior. They arise from embryological remnants of the notochord at the clivus, mobile spine, and sacrum. Chordomas are rare tumors in the pediatric age group. Their surgical management is difficult, given their propensity for inaccessible anatomical regions, and proximity to critical neurovascular structures. While en bloc resection with surgical margins has been advocated as the preferred approach for chordomas, tumor characteristics and violation of adjacent anatomical boundaries may not allow for safe en bloc resection of the tumor. Here, the authors present the case of a C1 chordoma in a 5-year-old boy with epidural and prevertebral extension. The patient’s treatment consisted of a far-lateral approach for resection of the tumor and C1 arch, followed by circumferential reconstruction of the craniocervical junction with an expandable cage spanning the skull base to C2, and posterior occipitocervical spinal instrumentation. At 42 months after surgery, the patient remains neurologically intact with stable oncological status, and no evidence of craniocervical junction instrumentation failure.

Abstract Myxoma is a benign tumor that arises from mesenchymal tissue and is found less commonly in the bone than in soft tissue. The majority of bony myxomas occur in the jaws. When compared with other odontogenic tumors, myxoma of the jaws is a rare entity. Numerous types of treatment have been used for these tumors including simple curettage, enucleation, curettage with peripheral ostectomy, and en bloc resection with or without immediate reconstruction. The buccal fat pad (BFP) is a lobulated mass of fatty tissue in the oromaxillofacial region, which has long been a source of grafts in facial augmentation. A case of an odontogenic myxoma in the left maxillary molar area of a 34-year-old female that was treated by curettage and peripheral ostectomy is presented. The surgical defect was successfully repaired with a pedicled BFP flap. Citation Öğütcen-Toller M, Şener I, Kasap V, Çakir-Özkan N.

Abstract Background The efficacy of the hanging maneuver for the retropancreatic nerve plexus (RNP) to enhance the confirmation of the margin status and to facilitate en-bloc resection for pancreatoduodenectomy (PD). In this report, we present the knack and pitfall of the hanging maneuver of the RNP. MethodsThe exit of the hanging maneuver of the RNP is the left part of the superior mesenteric artery (SMA), and the entry is the cranial part of the celiac axis. The entry of the hanging maneuver was connected to the dissection line on the right side of the celiac axis. Thereafter, the tape of the hanging maneuver was pulled to the right side, and the RNP was deployed widely. Finally, the RNP was easily dissected using a sealing device other than IPDA ResultsIt is important to clarify the entrance and exit of the hanging taping in this procedure. This permitted the wide spaces between the SMA, SMV, and the resected side, and it was easier to identify the IPDA. By traction of the hanging maneuver tape, a clear line may be drawn between the resection side and the remaining side. ConclusionsWith the correct implementation of the hanging maneuver, we believe that it would be possible to obtain reliable R0 resection as well as a reduction in blood loss and operation time.

Nowadays surgery is still the mainstay of solid tumors treatment. En Bloc resection is surgical treatment in amount of complete tumor removal. There remains considerable uncertainty about many aspects of resection boundaries, including definition and influence of anatomical and histological factors. One of the biggest challenges for the surgeon is choosing the right surgery for the «right» patient, taking into account the type of tumor and its biology.
