Interdigitating dendritic cell sarcoma (IDS) is a rare form of hematologic malignancy associated with an aggressive clinical course. Only 4 prior cases have been described as originating in the skin. We encountered two male patients ages 47 and 61years of age who presented with solitary cutaneous neoplasms diagnosed as IDS. Histologic exam showed a coalescing nested and multinodular proliferation of large pleomorphic epithelioid cells. In one case an initial diagnosis of melanoma was rendered. A recurrence 8months later was then interpreted as a primary cutaneous IDS...

BACKGROUND: Various studies have reported local recurrence (LR) rates after surgical treatment of lentigo maligna (LM) and lentigo maligna melanoma (LMM). However, the time to LR of LM/LMM is not currently known, as few studies report time to LR and have long-term follow-up. OBJECTIVE: To define time to LR in LM/LMM after surgical treatment, and to describe features of observed LR. MATERIALS AND METHODS: Retrospective single-center study of consecutive patients presenting with locally recurrent LM/LMM...

We report two cases of melanomas in patients who developed intestinal metastasis despite other metastatic sites responding to nivolumab and despite the patients having favorable findings such as vitiligo and normal lactate dehydrogenase. The first case is an 85-year-old man who had been administrated nivolumab for lung/cutaneous metastases. After 22 courses of nivolumab therapy, fever and anorexia had appeared and his bodyweight had decreased. An intussusception on the ileocecal valve was revealed by computed tomography, and emergency surgery revealed metastatic lesions on the colon...

The incidence of skin cancers, both non-melanoma as well as melanoma, are increasing in the United States. The ultraviolet radiation, mainly from sun, is considered the major cause for these neoplasms. While non-melanoma skin cancers are far more numerous, melanoma remains the most challenging. This is because melanoma can become extremely aggressive and its incidence is increasing worldwide due to lack of effective early detection, as well as disease recurrence, following both surgery and chemotherapy. Therefore, in addition to better treatment options, newer means are required to prevent melanomas from developing...

Radiotherapy is a non-surgical option for patients with non-melanoma skin cancer. Lesions in middle-aged to older patients with good performance status are typically prescribed 4-5 weeks of outpatient weekday treatment. Daily radiotherapy fraction sizes of 2-3 Gy are recommended to decrease the late cutaneous consequences such as in-field hypopigmentation and telangiectasia. In elderly, often unwell patients, these concerns are less of an issue and larger fraction sizes (5-7 Gy), referred to as hypofractionation, can be delivered over a shorter time yet still achieve excellent in-field control and improve a patient's quality of life and avoid the need for surgery...

A 10 yr old intact female German shepherd dog presented with a large peripheral odontogenic fibroma and malignant melanoma on her lower jaw. The tumor was resected with a unilateral subtotal rostral hemimandibulectomy. After the mandible was removed, it was devitalized intraoperatively by freezing it in liquid nitrogen. It was subsequently reimplanted. New bone tissue formed in the gap between the frozen bone and the host bone. The regenerated bone contained osteocytes, osteoblasts, and blood vessels. The cosmetic appearance of the dog was preserved...

CNS metastases have long been recognized as a common and late complication of systemic malignancies. They represent the most common tumor of the brain. As outcomes and overall survival improve with better tolerated and more durable responses from therapies for systemic cancers, the incidence and prevalence of brain metastases is likely to increase. Among the most common systemic cancers leading to brain metastases include lung, melanoma, breast (triple-negative histology) and renal cell cancers. To date, there has been infrequent involvement of gastrointestinal and gynecologic malignancies; however, this may also change, reflecting improvement in overall survival and therapeutic regimens...

The prognosis of stage IV metastatic melanoma is poor. An overal 1-year survival of 25.5% and a median survival of 6.2 months were reported without any significant improvement during the last 30 years before the introduction of new drugs (immune check point inhibitors and targeted therapies) which completely modified the therapeutic approach and induced an overwhelming improvement on the survival rates of these patients. This review will analyse the therapeutic tools available for the treatment of patients with metastatic melanoma, including adjuvant interferon and loco-regional therapies (surgery, radiotherapy and electrochemotherapy) and will mainly focus on the presentation of results obtained by the new treatments (check point inhibitors and targeted therapies)...

REVIEW
Daisuke Kudo, Akiko Suto, Kenichi Hakamada
Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal diseases to affect humans, regardless of whether patients receive multimodal therapy (including surgery, radiotherapy, and chemotherapy). This resistance to intervention is currently considered to be caused by the desmoplastic change of the extracellular matrix (ECM) in PDAC tissues, which is characterized by the accumulation of cancer-associated fibroblasts, collagen, proteoglycan, and hyaluronan. Among these ECM components, hyaluronan has attracted interest because various studies have indicated that hyaluronan-rich PDAC is correlated with the progressive properties of cancer cells, both in experimental and clinical settings...

The aim of this article is to investigate the latest knowledge of the aetiology, pathogenesis and treatment of mucosal malignant melanomas (MMM) in the gastrointestinal tract (GIT) and urogenital organs. MMM constitute 1.4% of all melanomas with an incidence rate in USA of 2.2 per million a year. MMM in the GIT occur mostly in the anal canal and rectum, but can also occur in the small intestine, gallbladder and the large intestine, though very rarely. Melanomas can occur in almost any part of the urinary tract...

To investigate local control and radiation-induced brain necrosis in patients with melanoma brain metastases who received complete resection plus fractionated stereotactic radiosurgery (fSRS, 3 × 9 Gy) or fSRS alone. Factors associated with the clinical outcomes and the development of brain necrosis have been assessed. One hundred and twenty consecutive patients with 137 melanoma brain metastases who received surgery plus fSRS (S + fSRS) or fSRS alone were analyzed. All lesions evaluated in the study were treated with a dose of 27 Gy given in 3 fractions over three consecutive days...

Lymphadenectomy is currently the standard treatment for melanoma patients with palpable lymph node (LN) metastasis. There is no recommendation as to the time when surgery should be performed in France. The aim of this retrospective study was to assess the impact of the time interval preceding lymphadenectomy on patient outcomes. Patients who underwent lymphadenectomy for LN macrometastasis (Stage IIIB/C AJCC) between 2005 and 2012 were included. Both the time interval between the first suspicion of LN recurrence (physical examination and imaging) and lymphadenectomy and the time interval between the multidisciplinary team meeting and lymphadenectomy were recorded...

Wide local excision and sentinel lymph node biopsy is the mainstay of treatment for patients with melanoma. As survival outcomes improve, longer term quality of life questions become more pertinent and this study aims to assess the factors which may play a role following surgery. A total of, 221 patients who underwent wide local excision and sentinel lymph node biopsy for melanoma (AJCC stage I and II) were recruited from three UK centres. These patients completed a patient outcome questionnaire, which included demographic and treatment data as well as quality of life and pain questionnaires...

PURPOSE OF REVIEW: The recent discovery of effective systemic treatments for melanoma has dramatically improved the prognosis for patients with advanced disease. As a result, the multidisciplinary management of melanoma has evolved significantly. In the past decades surgery was reserved for symptomatic palliation in patients with metastatic melanoma. Today surgical treatment of patients responding to systemic therapies has become an integral part of disease control. RECENT FINDINGS: Current efforts are focused on minimizing the morbidity of surgery (laparoscopic inguinal lymph node dissection, selective completion lymphadenectomy) as well as combining surgery with systemic therapy in novel ways (neoadjuvant targeted and/or immunotherapy, isolated limb infusion/perfusion with systemic immunotherapy)...

Importance: Melanoma in situ (MIS) is increasing in incidence, and expert consensus opinion recommends surgical excision for therapeutic management. Currently, wide local excision (WLE) is the standard of care. However, Mohs micrographic surgery (MMS) is now used to treat a growing subset of individuals with MIS. During MMS, unlike WLE, the entire cutaneous surgical margin is evaluated intraoperatively for tumor cells. Objective: To assess the outcomes of patients with MIS treated with MMS compared with those treated with WLE...

Uveal melanoma (UM), a rare cancer of the eye, is distinct from cutaneous melanoma by its etiology, the mutation frequency and profile, and its clinical behavior including resistance to targeted therapy and immune checkpoint blockers. Primary disease is efficiently controlled by surgery or radiation therapy, but about half of UMs develop distant metastasis mostly to the liver. Survival of patients with metastasis is below 1 year and has not improved in decades. Recent years have brought a deep understanding of UM biology characterized by initiating mutations in the G proteins GNAQ and GNA11...
