Аннотация
BACKGROUND: Basal cell carcinoma (BCC) is the most frequent skin cancer worldwide, however, its metastatic spreading is extremely rare.
CASE: We present a case of advanced BCC with rapid growth of new tumor lesions in a patient who was later diagnosed with Gorlin syndrome. Due to the advanced disease stage, the patient was examined for circulating tumor cells (CTCs), which are used as a prognostic marker in some metastatic malignancies. To date, no studies have been found that could assess the BCC tumor and the presence of CTCs in peripheral blood. CTCs were obtained after each surgical excision and during systemic oncological therapy from the peripheral venous blood by size-based isolation method (Metacell®) and cultured in vitro for 7 days. CTCs were enriched by size-based separation and examined using vital fluorescence microscopy. Cytomorphological comparison of CTCs with cells from the tumor lesions was provided. In the course of the treatment, the CTCs count in the blood decreased after surgical removal of the tumorous mass, but finally, the sustained and persisting decrease in CTCs was achieved with a hedgehog pathway inhibitor treatment.
CONCLUSION: The detection of CTCs points a systematic disease behavior in this case.
