In-transit metastasis of cutaneous squamous cell carcinoma: report of two cases.

Acta Dermatovenerol Alp Pannonica Adriat 2022 Jun;31(2):75-77

Department of Dermatology and Venereology, Haydarpaşa Numune Training and Research Hospital, Istanbul, Turkey.

Transit metastases include metastatic foci of the skin and subcutaneous tissue located between the tumor and the nearest regional lymph node. Although transit metastases have been described for malignant melanoma, some cases of transit metastases have also been reported among primary cutaneous non-melanoma cancers. Treatment of patients with in-transit squamous cell carcinoma (SCC) is a multimodal approach for advanced staging imaging and therapy, including Mohs micrographic surgery, adjuvant radiation, and possibly sentinel lymph node biopsy and immunotherapy or chemotherapy.

The Genetic Basis of Dormancy and Awakening in Cutaneous Metastatic Melanoma.

Cancers (Basel) 2022 Apr 23;14(9). Epub 2022 Apr 23.

Unit of Dermatology, University of Pisa, 56126 Pisa, Italy.

Immune dysregulation, in combination with genetic and epigenetic alterations, induces an excessive proliferation of uncontrolled melanoma cells followed by dissemination of the tumor cells to distant sites, invading organs and creating metastasis. Although immunotherapy, checkpoint inhibitors and molecular targeted therapies have been developed as treatment options for advanced melanoma, there are specific mechanisms by which cancer cells can escape treatment. One of the main factors associated with reduced response to therapy is the ability of residual tumor cells to persist in a dormant state, without proliferation. Read More
