Skin metastases from visceral cancers are rare and the reported incidence from all visceral cancers is 1.4% to 10%. Skin metastases from colorectal cancers account for only 5% of metastatic skin cancers, among which scalp metastases are very rare. We describe a 53-year-old man with scalp metastasis derived from sigmoid colon cancer that was diagnosed and surgically resected in 2005. Metastatic lung tumors that developed thereafter were surgically resected and then chemotherapy was administered. However, metastatic brain tumors occurred in 2008, and these were treated by gamma-knife radiosurgery. Around the same time, a raised lesion that appeared on the scalp was diagnosed as skin metastasis and treated with best supportive care. Thereafter, the brain metastases continued to spread, and the patient died in October 2008.

Background: Melanoma is an aggressive form of skin cancer, and single-modality treatments often fail to prevent tumor recurrence and metastasis. Combination therapy has emerged as an effective approach to improve treatment outcomes.
Methods: In this study, we developed a multifunctional nanoplatform, MIL@DOX@ICG, utilizing MIL-101-NH(Fe) as a carrier to co-deliver the chemotherapeutic agent doxorubicin (DOX) and the photosensitizer indocyanine green (ICG).

Angiogenesis, the expansion of pre-existing vascular networks, is crucial for normal organ growth and tissue repair, but is also involved in various pathologies, including inflammation, ischemia, diabetes, and cancer. In solid tumors, angiogenesis supports growth, nutrient delivery, waste removal, and metastasis. Tumors can induce angiogenesis through proangiogenic factors including VEGF, FGF-2, PDGF, angiopoietins, HGF, TNF, IL-6, SCF, tryptase, and chymase.

Chronic inflammation in the tumour microenvironment (TME) via Th2-polarisation promotes melanoma progression and metastasis, making it a target for immunotherapy. Interleukin (IL)-4 is considered essential for Th2-polarisation in the TME; however, its source remains unknown. Basophils have been postulated as one of its sources.

Introduction: Large melanomas, while relatively uncommon, present significant diagnostic challenges due to their size and potential to mimic other malignancies, leading to delays in appropriate treatment. Initial misdiagnosis is a substantial concern, impacting patient outcomes. This case highlights the importance of immunohistochemistry in cancer diagnosis, and of appropriate therapeutic management, which here included excision surgery of the tumor mass.

Introduction: Patients with metastatic melanoma to the lung typically have poor outcomes. Although a pulmonary metastasectomy for selected patients has been shown to improve survival, the role of surgical resection following the introduction of immunotherapy for metastatic melanoma is unknown. The objective of this study was to determine predictors of survival for patients with melanoma metastatic to the lung in the era of immunotherapy.
