Background: Fine needle aspiration cytology (FNAC) of the salivary glands is a routine procedure in the diagnostic workup of benign and malignant lesions. Primary malignant melanoma of the salivary gland is a rare disease, and only afew cases describing FNAC have been reported.
Case: We present a case of primary malignant melanoma of the right parotid gland. Cytomorphologically it was classified as adenocarrinoma. However, histologic examination revealed the diagnosis of malignant melanoma. At first clinical presentation of the patient, no other sites were involved. It was remarkable that 3 months after diagnosis of primary malignant melanoma in the right parotid gland, supraclavicular lymph nodes appeared on the left side. The patient underwent parotidectomy and neck dissection of both sites.
Conclusion: The cellular aspirates from primary malignant melanoma of the parotid gland were cytologically mistaken for adenocarcinoma. This cytologic pitfall required additional histologic examination.

Exercise and mindfulness-based interventions have growing evidence for managing fatigue and comorbid symptoms; however, packaging them in a cohesive digital way for patients undergoing cancer treatment has not been evaluated. We conducted a randomized controlled trial to assess the impact of a 12 week digital integrative medicine program, Integrative Medicine at Home (IM@Home), versus enhanced usual care on fatigue severity (primary outcome), comorbid symptoms and acute healthcare utilization (secondary outcomes), in 200 patients with solid tumors experiencing fatigue during treatment. Fatigue severity decreased more in IM@Home than in the control (1.

Adoptive cell therapy with tumor-infiltrating lymphocytes (TIL) can mediate tumor regression, including complete and durable responses, in a range of solid cancers, most notably in melanoma. However, its wider application and efficacy has been restricted by the limited accessibility, proliferative capacity and effector function of tumor-specific TIL. Here, we develop a platform for the efficient identification of tumor-specific TCR genes from diagnostic tumor biopsies, including core-needle biopsies frozen in a non-viable format, to enable engineered T cell therapy.

Neoadjuvant immunotherapy represents a pioneering approach in the preoperative treatment of cancer, offering novel avenues for tumor reduction and improved patient outcomes by modulating the immune response. This study investigated neoadjuvant immunotherapy using intratumoral administration of mannan-BAM, Toll-like receptor ligands, and antiCD40 antibody (MBTA therapy) followed by surgery in murine models of mouse tumor tissue (MTT) pheochromocytoma, B16-F10 melanoma, and 4T1 and E0771.lmb mammary carcinomas.
