Abstract Background Anorectal malignant melanoma (ARMM) has an extremely poor prognosis, and there is no report of resection of liver metastases so far. We report herein a rare case of postoperative laparoscopic partial hepatic S7 resection for rectal malignant melanoma. Case presentation A 51-year-old female patient with a diagnosis of an ARMM underwent a laparoscopic rectal amputation. Eleven months later, computed tomography (CT) revealed a 14-mm nodule in liver segment 7 (S7), which was diagnosed as a hepatic recurrence of the ARMM. Because no other recurrences were found, a laparoscopic partial resection of S7 was performed. Pathological analysis found intracellular melanin deposition, and immunostaining was S-100 (+), HMB-45 (+), and SOX-10 (+). Based on these findings, a liver metastasis of malignant melanoma was diagnosed. The patient is alive 7 months after the second surgery and has so far experienced no recurrences. Conclusion We reported an extremely rare case of a laparoscopic resection of a liver metastasis following surgery for ARMM.

Abstract Background: Adrenocortical carcinoma(ACC) is a rare and highly invasive endocrine malignant tumor with poor prognosis and insensitivity tochemotherapy, which don't have effective treatment. Although Surgical resection is considered to be the main treatment for ACC, postoperative recurrence and metastasis have become the most important factors of death. Therefore, local treatments such as trans-catheter arterial chemo-embolization, radiofrequency ablation become be new treatment for ACC. Trans-catheter arterial chemo-embolization therapy for ACC patients with liver metastasis has good efficacy and can effectively reduce the tumor burden of patients, which is considered to be safe and easy for patients. Case presentation: We report a 47-year-old female patient diagnosed with stage Ⅳ ACC with liver metastases, who developed symptoms of acute adrenocortical dysfunctions after hepatic arterial catheter chemo-embolization.Conclusion: Trans-catheter arterial chemo-embolization therapy for ACC patients with liver metastasis is not completely safe, and there is a certain probability that it will lead to secondary adrenal dysfunction. Hydrocortisone supplementation can effectively alleviate the symptoms.

Pathological Analysis

Malignant melanoma of the urethra is a rare tumour that is difficult to diagnose and treat, resulting in a poor prognosis. In this paper, we present the case of a 65-year-old woman who was referred to a gynaecologist because of a urethral mass that mimicked a caruncle. The tumour was removed by local excision, and a pathological analysis revealed a malignant melanoma. Distal urethrectomy was performed after three months with no evidence of residual tumour. There was no evidence of disease at a six-year followup. In this paper, we compare the epidemiology, treatment, staging, and prognosis of vulvar cancer in general to malignant melanoma of the vulva in particular.

The article presents a rare case report about the use of thoracoscopic transdiaphragmatic approach to resection of a solitary segment VIII metastasis in the liver (1.5 × 1.2 cm). Taking into account the difficulty of laparoscopic resection of postero ‑superior segments of the liver, a decision was made to refrain from laparotomy and to perform a safe minimally invasive surgery using an approach, which is rare at the current stage. The article also presents the analysis of published literature and discussion of a non‑ standard approach in this clinical case.

Malignant melanoma is extremely rare neoplasm arising from uncontrolled growth of melanocytes, accounting for 0.5% of all oral malignancies. It has a great tendency to metastasize and locally invade tissues more readily than any other malignant tumor of the oral cavity. It present as the rare oral malignant condition, asymptomatic and poor prognosis. The necessity of a highly specialized treatment is factors that should be seriously considered by the involved health care provider. Herein, we report a rare and interesting case of oral malignant melanoma of the maxillary anterior gingiva, which was clinically and histo-pathologically diagnosed with a brief review of literature, has been discussed.

Abstract Background We report a rare case of primary abdominal cocoon with bilateral cryptorchidism. Case presentation The patient had a history of laparoscopic surgery for bilateral cryptorchidism 6 years earlier. He was admitted to the hospital again due to intestinal obstruction. Surgery was performed on the patient after the failure of conservative treatment. The patient was diagnosed with primary abdominal cocoon. Instead of the greater omentum, many cocoon-like tissues surrounding the bowel were seen during operation. Abdominal surgery can increase the risk of intestinal adhesion, which is one of the main causes of intestinal obstruction, especially in patients with abdominal cocoon. We hypothesize that the surgery 6 years earlier to address transabdominal bilateral cryptorchidism accelerated the patient’s intestinal obstruction. Conclusion This case implies that it is important for urologists to evaluate whether their patients exhibit abdominal cocoon before cryptorchidism surgery, to choose better surgical methods and reduce the risks of poor prognosis.

Abstract Background: IMTs are extremely rare in eyes. This is the first report of a IMT of the ciliary body.Case presentation: A ciliary body tumor was found under slit lamp biomicroscopy in a 55-year-old male first diagnosed with cataract. Then this patient underwent trans-sclera resection via partial lamellar sclerouvectomy and par plans vitrectomy to remove the mass. Hematoxylin and eosin (HE) staining and immunohistochemistry findings showed that the characteristics of the tumor were consistent with inflammatory myofibroblastoma tumor (IMT).Conclusions: we reported a rare case of intraocular IMT, which is confirmed by H&E staining, and IHC positive staining for Vimentin, Desmin and ALK, while negative staining for SMA, S-100, ki-67, CK, CD68, and calponin.

Background: Isolated intracranial Rosai-Dorfman disease (RDD) is an extremely rare, idiopathic histo-proliferative disorder. RDD is associated with the proliferation of histiocytes and emperipolesis. Case Presentation: we report a case with isolated intracranial RDD. A 47-year- old man presented with a dizziness, falling, and then secondary generalized seizure, hemiparesis and right hemisensory deficit. This case preoperatively was misdiagnosed with meningioma. Histopathological examination revealed pale histiocytes displaying emperipolesis which were positive for S-100 and CD68 proteins and negative for CD1a marker. BRAF V600E mutation was negative. Conclusion: In this case, total resection was performed and clinical symptoms were regressed completely.
