Collision tumors are characterized by the coexistence of two cancers in the same anatomical site and its pathogenesis remains controversial. Although uncommon, the association of basal cell carcinoma and melanocytic nevus is the most common among combinations of skin tumors. Even rarer is the association of two malignant tumors. We report a case of tumor collision representing melanoma and basosquamous cell carcinoma, a combination not previously described in the literature, since there are no reported cases of melanoma with this type of basal cell carcinoma.
碰撞瘤的特征是在同一解剖部位同时存在两种癌症，其发病机制仍存在争议。虽然不常见，但基底细胞癌和黑素细胞痣的关联是皮肤肿瘤组合中最常见的。两种恶性肿瘤的关联更为罕见。我们报告一例肿瘤碰撞病例，表现为黑色素瘤和基底鳞状细胞癌，这是一种此前文献中未描述过的组合，因为尚无黑色素瘤与这种类型基底细胞癌相关的病例报道。
