The purpose of this paper is to highlight the risk of early malignant transformation in infants with giant congenital melanocytic nevi (GN) and demonstrate the potential for earlier intervention with aggressive surgery. We describe the case of a child born with a GN who developed a metastatic melanoma early in life, despite early commencement of resection of the nevus. This is contrasted against a second case of a child in which a more radical management was conducted. Despite early commencement of serial resection of the GN, the first child in this series died of metastatic melanoma prior to complete excision of the nevus...

The advent of immune checkpoint inhibitors anti-PD-1/PD-L1 has delivered new and effective treatment options with proven clinical benefits for patients affected by metastatic melanoma. The 30-40% of treated patients experience an objective tumour regression, with a significantly prolonged survival and an improved quality of life. Here, we report a case of a 75-year-old Caucasian woman affected by a massive cutaneous metastasis from a BRAF wild-type melanoma who experienced multiple relapses after surgery and repeated electrochemotherapy treatments...

We report an unusual complication following placement of a thoracic epidural catheter in a patient that had undergone surgery for pulmonary metastases of a malignant melanoma. The intra- and postoperative course was initially without complications. At 2 days, there was a small, conspicuous swelling above the site of epidural puncture, which was neither reddened nor painful. No neurological deficits were observed, and the patient explained that he had been aware of the swelling for more than 6 months; thus, the epidural catheter was not deemed to be responsible...

Primary malignant melanoma of the gastrointestinal tract is extremely rare. A 35-year-old man presented with complaints of abdominal pain and weight loss. Contrast enhanced computed tomography showed a large mass involving the duodenum and the superior mesenteric vessels. Upper gastrointestinal endoscopy demonstrated a large, friable mass along the duodenal wall and biopsy was suggestive of malignant melanoma. A detailed physical examination and whole body imaging (positron emission tomography and computed tomography) did not reveal any other lesion...

Small bowel obstructions (SBOs) are common. Adhesions make up the majority of cases at 84.9%, followed by abdominal herniae and malignancies. A 71-year-old female presented with total constipation, abdominal distension, on a background of resected cutaneous melanoma nine years prior. A CT-scan showed small bowel intussusception and disseminated mucosal-enhancing lesions consistent with metastases. She was brought to the operating theatre where six areas of intussusception were identified and manually reduced...

Melanoma is an aggressive malignancy that is increasingly common and exhibits a poor patient survival rate. Radiotherapy is the primary option for patients with melanoma, particularly those who are not candidates for surgery; however, the therapeutic effect is limited due to the relative radioresistance of melanoma to ionizing radiation (IR). It has been reported that microRNAs (miRNAs) serve a vital role in determining the radiosensitivity of tumors; however, little is known concerning the radiosensitization of melanoma using miRNA...

Non-melanoma skin cancer incidence is rising worldwide. The leading neoplasias are basal cell carcinoma and squamous cell carcinoma. We report on an 88-year-old female patient with a rapidly grown, symptomless, exophytic tumor of the supraclavicular area. Examination at the dermatology department has revealed a firm, exophytic, reddish tumor covered by crusts, about 4 cm in diameter and easily movable to the ground. The tumor was removed by delayed Mohs surgery (R0 resection). The resulting defect was closed by tissue expansion...

Vaginal melanoma is a rare tumor, accounting for <1% of all melanomas and ~1-5% of all vaginal malignant tumors. The prognosis of vaginal melanoma is extremely poor, as it is often resistant to chemotherapy and radiotherapy, and metastases may develop in the early stages of the disease. The present study investigated 5 patients with vaginal melanoma treated at the Department of Gynecology of Osaka City University Hospital (Osaka, Japan) between October, 2000 and April, 2014. All the cases presented with abnormal genital bleeding as the main complaint...

BACKGROUND: Surgery for scalp malignancies is aimed at the complete resection and a good aesthetic outcome. The goal was to develop an algorithm for scalp reconstruction based on the authors' surgical experience. METHODS: This is a retrospective analysis of 123 procedures of scalp malignancies in 105 patients. Twenty eight procedures were for resection of squamous cell carcinoma, 54 for basal cell carcinoma, and 41 for suspected melanomas. RESULTS: Primary closure (27 procedures), local flap (LF; 19), split-thickness skin graft (SG; 64), rotated LF and SG (9), and free vascularized flaps (4) were used...

RATIONALE: Primary malignant melanoma of the esophagus (PMME) is a rare disease with an extremely poor prognosis. In contrast, melanocytosis is a benign condition defined as melanocytic proliferation with melanin deposition. PMME is often accompanied by melanocytosis, but differentiating between them is difficult because of their similar appearance. PATIENT CONCERNS: Here, we reported 3 PMME cases, 2 with melanocytosis. DIAGNOSES: Magnifying endoscopy revealed characteristic non-uniform pigmented spots along deformed intrapapillary capillary loops (IPCLs) in PMME, while melanocytosis showed fine granule-like or linearly arranged spots and intact IPCLs...
