The impact of cooling methods on the maximum temperature of the processed object during side milling
This article presents the changes in temperature distribution concerning the processed object during side milling. The analysis included the influence of selected cooling methods (cold air from vortex tube, cooling with compressed air, and without cooling) on the maximum temperature of the processed object during the process of milling. Measurement of the maximum temperature was conducted with the use of thermocouples and a thermal camera
Extremely Rare Pulmonary Metastases of Skin Basal Cell Carcinoma: Report of Two Cases with Clinicopathological Features
Basal cell carcinoma (BCC) is the most frequent human skin cancer, but metastasizing BCC (MBCC) is extremely rare, developing in approximately 0.0028% to 0.55% of BCC patients. Herein, we report two cases of pulmonary MBCC. The first one developed in a 72-year-old male who underwent surgical resection due to multiple recurrences and adjuvant radiotherapy. Immunohistochemistry showed that neoplastic cells expressed Ber-EP4, CK5/6, p63, EMA (focally), BCL-2, and CD10, but were negative for CK7, CK20, S100, estrogen and progesterone receptors, and TTF-1. The second case is a 64-year-old female treated with vismodegib. Clinicopathological features and differential diagnoses are described
