The leaflet summarises a guideline (melanomafocus.

If you would like more (melanomafocus.com/activities/mucosal- information about your individual situation, guidelines/mucosal-melanoma-resources). you should discuss this with your clinical team. Mucosal melanomas are very rare: in the Surveillance Epidemiology and End Results (SEER) database which registered melanomas over 22 years, only about 1 melanoma in 100 was a mucosal melanoma. The majority of melanomas grow within the skin. Mucosal melanomas can be more complicated to treat than skin melanomas as they are often diagnosed later. This is because they are in less visible places and because they are often not pigmented (darker), which makes them even more difficult to spot. B 1 What are the symptoms?

A greater understanding of these factors significantly helps the clinician to delineate in advance the appropriate staging, prognosis and treatments. The primary factors which determine the biologic behavior of a melanoma in a dog are site, size, stage and histologic parameters. Unfortunately, even with an understanding of all of these factors, there will be occasional melanomas which have an unreliable biologic behavior; hence the desperate need for additional research into this relatively common (~ 4% of all canine tumors), heterogeneous, but frequently extremely malignant tumor. This review will assume the diagnosis of melanoma has already been made, which in of itself can be fraught with difficulty, and will focus on the aforementioned biologic behavior parameters, the staging and the treatment of canine melanoma. Biologic Behavior The biologic behavior of canine melanoma is extremely variable and best characterized based on anatomic site, size, stage and histologic parameters. On divergent ends of the spectrum would be a 0.5 cm haired-skin melanoma with an extremely low grade likely to be cured with simple surgical removal vs. a 5.0 cm high-grade malignant oral melanoma with a poor-grave prognosis. Similar to the development of a rational staging, prognostic and therapeutic plan for any tumor, two primary questions must be answered; what is the local invasiveness of the tumor and what is the metastatic propensity? The answers to these questions will determine the prognosis, and to be discussed later, the treatment.

  • Melanomas Are Comprised of Multiple Biologically Distinct Categories
    Melanomas are comprised of multiple biologically distinct categories, which differ in cell of origin, age of onset, clinical and histologic presentation, pattern of metastasis, ethnic distribution, causative role of UV radiation, predisposing germ line alterations, mutational processes, and patterns of somatic mutations. Neoplasms are initiated by gain of function mutations in one of several primary oncogenes, typically leading to benign melanocytic nevi with characteristic histologic features. The progression of nevi is restrained by multiple tumor suppressive mechanisms. Secondary genetic alterations override these barriers and promote intermediate or overtly malignant tumors along distinct progression trajectories. The current knowledge about pathogenesis, clinical, histological and genetic features of primary melanocytic neoplasms is reviewed and integrated into a taxonomic framework.

  • Lymphatic Invasion and Angiotropism in Primary Cutaneous Melanoma Andrea P Moy, Lyn M Duncan and Stefan Kraft
    Laboratory Investigation (2017) 97, 118–129 © 2017 USCAP, Inc All rights reserved 0023-6837/17 $32.00 PATHOBIOLOGY IN FOCUS Lymphatic invasion and angiotropism in primary cutaneous melanoma Andrea P Moy, Lyn M Duncan and Stefan Kraft Access of melanoma cells to the cutaneous vasculature either via lymphatic invasion or angiotropism is a proposed mechanism for metastasis. Lymphatic invasion is believed to be a mechanism by which melanoma cells can disseminate to regional lymph nodes and to distant sites and may be predictive of adverse outcomes. Although it can be detected on hematoxylin- and eosin-stained sections, sensitivity is markedly improved by immunohistochemistry for lymphatic endothelial cells. Multiple studies have reported a significant association between the presence of lymphatic invasion and sentinel lymph node metastasis and survival. More recently, extravascular migratory metastasis has been suggested as another means by which melanoma cells can spread. Angiotropism, the histopathologic correlate of extravascular migratory metastasis, has also been associated with melanoma metastasis and disease recurrence. Although lymphatic invasion and angiotropism are not currently part of routine melanoma reporting, the detection of these attributes using ancillary immunohistochemical stains may be useful in therapeutic planning for patients with melanoma.

(Accepted for publication, February 8, 2010) Abstract: Focal pigmented melanocytic lesions rarely occur in the oral cavity but should not be taken for granted for they may represent markers or risks for oral mucosal melanoma (OMM). The study investigated the clinical and pathological features of focal pigmented lesions of melanocytic origin focusing on oral melanotic macule (oral MM), oral pigmented nevus (OPN) and OMM. Immunohistochemistry was employed with S100, HMB-45, Melan A, c-kit and Ki-67. Oral MM mostly occurred on the gingiva and buccal mucosa while OPN mostly occurred on the buccal mucosa. OMM occurred on the palate and gingiva. A female gender predilection was observed in oral MM. Most of the benign lesions were less than 6 mm in diameter while OMM had greater than 10 mm in diameter. Benign lesions occurred in almost the same location as that of OMM.
