Parnian Ahmadi Moghaddam, Kristine M Cornejo, Lloyd Hutchinson, Keith Tomaszewicz, Karen Dresser, April Deng, Patrick OʼDonnell
Merkel cell carcinoma (MCC) is a rare primary cutaneous neuroendocrine tumor that typically occurs on the head and neck of the elderly and follows an aggressive clinical course. Merkel cell polyomavirus (MCPyV) has been identified in up to 80% of cases and has been shown to participate in MCC tumorigenesis. Complete spontaneous regression of MCC has been rarely reported in the literature. We describe a case of a 79-year-old man that presented with a rapidly growing, 3-cm mass on the left jaw. An incisional biopsy revealed MCC...

OBJECTIVE: Sentinel lymph node (SLN) mapping for endometrial (EC) and cervical cancers (CC) is a current technique that could provide benefits over traditional lymphadenectomy. Near-infrared (NIR) fluorescence imaging is a promising technique to perform this procedure. We conducted a systematic review of the evidence regarding the technique and the effectiveness of indocyanine green (ICG) during SLN biopsy, using robotic and laparoscopic assisted surgery and laparotomy. MATERIALS AND METHODS: We conducted a computer literature search for published English language studies in humans using PubMed since January 2010 up to May 2015...

Sentinel lymph node biopsy is a crucial part of staging intermediate and thick melanoma. Lymphatic drainage from a tumor site can be highly variable, especially on the head, neck, and trunk. SPECT/CT fuses nuclear medicine and x-ray CT images to produce images with high anatomic detail. At our institution, SPECT/CT is performed routinely in addition to planar imaging. This article presents examples where SPECT/CT has proven helpful in image interpretation.

Melanoma is an important public health problem, and its incidence is increasing worldwide. The disease status of regional lymph nodes is the most important prognostic factor in early-stage melanoma patients. Sentinel lymph node biopsy (SLNB) was introduced in the early 1990s as a less invasive procedure than complete lymph node dissection to allow histopathologic evaluation of the "sentinel lymph node" (SLN), which is the first node along the lymphatic pathway from a primary tumor. Sentinel lymph node biopsy has minimal complication risks compared with standard complete lymph node dissection...

We report a case of a 36-year-old woman that presented with a painful mass in the outer quadrants of the left breast that had grown rapidly. Physical examination revealed a well circumscribed elastic mass and breast ultrasound showed a cyst measuring 26 mm with vegetation growing on the inner wall. Microscopic evaluation, after fine needle aspiration cytology (FNAC), suggested benign lesion. Tumorectomy was performed and the final diagnosis was a pure squamous cell carcinoma (SCC) of the breast. A simple mastectomy with sentinel node biopsy was performed...

BACKGROUND AND AIM: Cutaneous squamous cell carcinoma (CSCC) is a malignant epithelial cell tumor. CSCC has a tendency to spread via lymphogenic pathway. Metastases are found in 2%-6% of cases. Prognosis of patients with CSCC is directly related to the morphology and localization of primary tumor. The aim of this study was to evaluate the recurrence-free survival of patients with CSCC after tumor excision and SLNB as well as to analyze morphologic CSCC features related to patient recurrence-free survival...

With the improvement of neoadjuvant chemotherapy (NAC), the proportion of pathological complete response (pCR) in the breast and axillary lymph node (ALN) is increasing. The evaluation of pCR does not include the status of internal mammary lymph node (IMLN). This study is to evaluate the roles of both axillary sentinel lymph node biopsy (ASLNB) and internal mammary sentinel lymph node biopsy (IM-SLNB) in breast cancer patients after NAC. There were 74 patients enrolled into this study. IM-SLNB was performed on patients with radioactive internal mammary sentinel lymph node (IM-SLN)...

With the advent of sentinel lymph node biopsy, surgical methods for accurately staging the axilla in patients with early-stage breast cancer have become progressively less extensive, with formal axillary lymph node dissection confined to a dwindling group of patients. Although details of methods for sentinel lymph node biopsy have yet to be standardised, this technique is now widely practised and accepted as standard of care worldwide. In the past 5 years, attention has focused on minimisation of surgical morbidity by restricting further axillary surgery or considering radiotherapy in patients with a small tumour burden in their sentinel nodes...

BACKGROUND: In early breast cancer, the optimal technique for sentinel lymph node biopsy (SLNB) is the combined technique (radioisotope and Patent Blue V) which achieves high identification rates. Despite this, many centres have decided to stop using blue dye due to blue-dye-related complications (tattoo, anaphylaxis). We evaluated the SLNB identification rate using the combined technique with and without Patent Blue V and the blue-dye-related complication rates. METHODS: Clinical and histological data were analysed on patients undergoing SLNB between March 2014 and April 2015...

OBJECTIVE: The purpose of this article is to describe the feasibility and safety of a multidisciplinary approach to imaging-guided axillary staging that facilitates personalized, less invasive surgical management of the axilla through targeted axillary dissection in patients with biopsy-proven nodal metastasis undergoing neoadjuvant chemotherapy. CONCLUSION: Axillary nodal status, critical in breast cancer staging, affects prognosis and treatment. As the paradigm shifts toward minimally invasive therapy, a clip marker is placed in the biopsied metastatic node for patients with N1-N2 disease undergoing neoadjuvant chemotherapy to facilitate targeted axillary dissection of the clipped node...

Recent meta-analyses and a prospective multicenter trial of sentinel node (SN) mapping in early gastric cancer have demonstrated acceptable SN detection rates and accuracy of determination of lymph node status. SN mapping may play a key role in obtaining individual metastatic information. It also allows modification of surgical procedures, including function-preserving gastrectomy in patients with early gastric cancer. A dual-tracer method that uses radioactive colloids and blue dye is currently considered the most reliable method for the stable detection of SNs in patients with early gastric cancer...

BACKGROUND: On April 1, 2015, Odense University Hospital (OUH) began a new diagnostic strategy, wherein all malignant melanoma (MM) patients in the Region of Southern Denmark with a positive sentinel lymph node biopsy (SLNB) underwent FDG-PET/CT preoperatively prior to lymph node dissection (LND). The purpose of this study is to determine FDG-PET/CT's efficacy in finding distant metastasis in the first year after the implementation of this new strategy, and to what extent these findings influence subsequent diagnostic testing and treatment in this patient group...

PURPOSE: Merkel cell carcinoma (MCC) is an aggressive cutaneous malignancy. However, factors associated with disease presentation and outcomes remain uncertain, especially in light of recent changes in workup, such as sentinel lymph node biopsy. Therefore, this study used the SEER database to examine factors that could affect stage at presentation and treatment. METHODS: We identified 4,543 patients and evaluated associations between sex, race, age, primary disease site, disease presentation, and treatment...

OBJECTIVE: To evaluate the role of preoperative axillary staging with ultrasound (US) and fine needle aspiration cytology (FNAC). Can we avoid intraoperative sentinel lymph node (SLN) examination, with an acceptable revision rate by preoperative staging? DESIGN: This study is based on the retrospective data of 336 patients that underwent US evaluation of the axilla as part of their staging. A FNAC biopsy was performed when abnormal lymph nodes were visualized. Patients with normal appearing nodes on US or a benign diagnostic biopsy had removal of the SLNs without intraoperative pathological examination...

BACKGROUND AND PURPOSE: Malignant melanoma (MM) on the trunk, because of its anatomical location, has multiple potential lymphatic basins to which to drain. The aim of this study is to map the location of the sentinel lymph node (SLN) on the basis of the anatomical location of the primary malignant melanoma on the trunk. METHODS: Patients diagnosed with MM on the trunk who had undergone a SLN biopsy from January 2006 to March 2015 were identified in the Christie NHS Foundation Trust through a computer database search...

BACKGROUND: Papillary carcinoma (PC) of the breast represents ∼0.5% of all newly diagnosed cases of breast cancer and usually has an indolent course. The current data suggest lack of a consensus in the surgical management of this disease. Because patients can occasionally develop metastatic disease, sentinel lymph node (SLN) biopsy is often performed during surgery. MATERIALS AND METHODS: In the present study, we retrospectively evaluated the histologic characteristics of 99 cases of PC with or without associated frank invasive carcinoma, including 43 encapsulated or intracystic PCs, 24 solid PCs, and 32 intraductal PCs, and correlated these with the incidence of nodal metastasis...

Malignant peripheral nerve sheath tumors are rare soft tissue sarcomas with histological and immunohistochemical similarities to spindle cell melanoma. Although spindle cell melanoma is significantly more common, both tumors may express S100 and lack staining for HMB-45, Melan-A, or MITF. Here we present a case of superficial malignant peripheral nerve sheath tumor with diffuse S100 positivity arising in a subtle neurofibroma in close proximity to an intradermal melanocytic nevus. This configuration had led to prior misdiagnosis as a desmoplastic melanoma arising in the nevus and to sentinel lymph node biopsy...
