Management of Clitoral Melanoma Presenting as an Exophytic Clitoral Mass: A Case Report and Review of the Literature.

Curr Oncol 2021 10 21;28(6):4264-4272. Epub 2021 Oct 21.

Department of Obstetrics and Gynecology, David Geffen School of Medicine, University of California Los Angeles, Los Angeles, CA 90095, USA.

Primary mucosal melanomas of the female genital tract account for one percent or less of all cases of melanoma with even fewer originating in the clitoris. Given the rarity of diagnosis of clitoral melanoma, there is a paucity of data guiding management. There is no supporting evidence that radical vulvectomy (with or without inguinal lymphadenopathy) is associated with improved disease-free or overall survival compared to partial vulvectomy or wide local excision.

Histological regression in melanoma: impact on sentinel lymph node status and survival.

Mod Pathol 2021 11 10;34(11):1999-2008. Epub 2021 Jul 10.

Melanoma Institute Australia, The University of Sydney, Sydney, NSW, Australia.

Regression in melanoma is an immunological phenomenon that results in partial or complete replacement of the tumor with variably vascular fibrous tissue, often accompanied by pigment-laden macrophages and chronic inflammation. In some cases, tumor-infiltrating lymphocytes (TILs) may represent the earliest phase of this process. The prognostic significance of regression has long been a matter of debate, with inconsistent findings reported in the literature to date. Read More

Detection of cancer metastasis: past, present and future.

Clin Exp Metastasis 2022 02 7;39(1):21-28. Epub 2021 May 7.

Moffitt Cancer Center, Department of Pathology, 12902 Magnolia Drive, Tampa, FL, 33612, USA.

The clinical importance of metastatic spread of cancer has been recognized for centuries, and melanoma has loomed large in historical descriptions of metastases, as well as the numerous mechanistic theories espoused. The "fatal black tumor" described by Hippocrates in 5000 BC that was later termed "melanose" by Rene Laennec in 1804 was recognized to have the propensity to metastasize by William Norris in 1820. And while the prognosis of melanoma was uniformly acknowledged to be dire, Samuel Cooper described surgical removal as having the potential to improve prognosis. Read More

T cell infiltration on local CpG-B delivery in early-stage melanoma is predominantly related to CLEC9ACD141 cDC1 and CD14 antigen-presenting cell recruitment.

J Immunother Cancer 2021 03;9(3)

Department of Medical Oncology, Amsterdam University Medical Centers, Vrije Universiteit, Cancer Center Amsterdam, Amsterdam, The Netherlands

Background: We previously reported CpG-B injection at the primary tumor excision site prior to re-excision and sentinel node biopsy to result in immune activation of the sentinel lymph node (SLN), increased melanoma-specific CD8 T cell rates in peripheral blood, and prolonged recurrence-free survival. Here, we assessed recruitment and activation of antigen-presenting cell (APC) subsets in the SLN and at the injection site in relation to T cell infiltration.

Methods: Re-excision skin specimens from patients with clinical stage I-II melanoma, collected 7 days after intradermal injection of either saline (n=10) or 8 mg CpG-B (CPG7909, n=12), were examined by immunohistochemistry, quantifying immune subsets in the epidermis, papillary, and reticular dermis.
