Colonic Metastasis of Palatine Tonsillar Melanoma Presenting as Colocolic Intussusception

Turkish Journal of Colorectal Disease, 2020
Primary mucosal melanomas account for 0.8%-3.7% of all the melanomas. More than half of the primary melanomas arise in the head and neck region, with nose and paranasal sinus being the most common site.

Alpha‐Synuclein Promotes Anterograde Vesicle Transport in Melanocytes and Melanoma Cells: A Pro‐Survival Function

Journal of the Chinese Chemical Society, EarlyView.
Model for how α‐syn modulates the positioning of endolysosomes in melanoma cells. (a) α‐syn tethers endolysosomes to the plasma membrane, a last step in anterograde transport. (b) Loss of α‐syn expression causes the loss of the tethering function, which leads to perinuclear vesicle clustering. Reproduced from the open access article.

Analysis of Treatment Patterns for Mucosal Melanoma Using Real-World Data in the SEER-Medicare-Linked Database. [PDF]

Cancer Med
ABSTRACT Background Mucosal melanoma (MM) is a rare, aggressive disease, often diagnosed late, and associated with poor survival. Surgical resection is the main potential curative option, but anatomical complexity limits feasibility, and real‐world evidence on treatment patterns remains scarce.

Cutaneous Pigmentary Changes During Setmelanotide Therapy: Dermoscopic and Confocal Findings in Two Patients

JEADV Clinical Practice, EarlyView.
ABSTRACT Setmelanotide is a melanocortin‐4 receptor agonist approved for the treatment of rare forms of genetic obesity. Through off‐target activation of the melanocortin‐1 receptor, it may induce cutaneous pigmentation changes; however, data regarding its effects on melanocytic nevi remain limited.

Plasma Cell Mucositis: A 20‐Year Retrospective Review at a Tertiary Center

JEADV Clinical Practice, EarlyView.
ABSTRACT Background Plasma cell mucositis (PCM) is a rare, chronic inflammatory condition of mucosal surfaces that is likely underdiagnosed and underreported, with limited data on its clinical characteristics, extracavitary involvement, and treatment outcomes.

MUCOSAL MELANOMAS OF THE HEAD AND NECK

Nippon Jibiinkoka Gakkai Kaiho, 1988
Twelve patients with the mucosal malignant melanomas of the head and neck had been treated in our department during 15 years from 1972 to 1987. Among these 12 cases, 7 melanomas were found either in the nasal cavity or paranasal sinus, 3 melanomas in the oral cavity, and 2 melanomas in the pharynx (nasopharynx or oropharynx).These cases were classified

Impact of Co‐Morbid Immunocompromise in HPV‐Associated Oropharyngeal Squamous Cell Carcinoma

The Laryngoscope, EarlyView.
Among patients with surgically resected Human Papillomavirus positive (HPV+) oropharyngeal squamous cell carcinoma (OPSCC), immunocompromised patients had significantly worse overall survival compared to the non‐compromised group; however, these exploratory findings should be interpreted cautiously.

Patients' Characteristics, Histopathological Findings, and Tumor Stage in Different Types of Malignant Melanoma: A Retrospective Multicenter Study

Acta Medica Iranica, 2017
Cutaneous malignant melanoma (CMM) is currently the most fatal of skin cancers accounting for 50000 deaths annually. Five distinct melanomas are described histopathologically: superficial spreading, lentigo maligna, nodular, acral lentiginous and mucosal

Genetic analysis of primary lung interdigitating dendritic cell sarcomas

The Journal of Pathology, EarlyView.
Abstract Interdigitating dendritic cell sarcomas (IDCSs) are rare tumors that commonly arise in the hematopoietic system and rarely outside. The genetic drivers of IDCS carcinogenesis are unknown; therefore, therapeutic options are limited. We investigated somatic gene mutations and copy‐number alterations (CNAs) in nine IDCSs arising in the lung by ...
