ABSTRACT
Primary cutaneous adenosquamous carcinomas are very rare with only few published reports. The histopathologic finding consists of two different components - mucin secreting cells (adenocarcinoma) and squamous cells (squamous cell carcinoma). We experienced a case of occipital scalp adenosquamous carcinoma, which is an extremely rare neoplasm in scalp. The lesion is histologically distinctive because of the presence of mixed areas of unequivocal adenocarcinoma and squamous cell carcinoma. It is found that combined surgery and additional radiation therapy is necessary because the biological behavior and prognosis of this neoplasm are considered as more aggressive and worse than that of conventional squamous cell carcinoma.

The metastasis of nodal pattern of malignant scalp tumors of the posterior half of the scalp including the occipital area and the nape of the neck takes place primarily in the retro-auricular and suboccipital area, and secondarily in the posterior triangle of the neck. The regional node dissection that includes the removal of the retro-auricular and suboccipital nodes in continuity with the posterior triangle and jugular chain of lymph nodes is called the posterolateral neck dissection. Recently, we experienced a case of an extended posterolateral neck dissection for recurred squamous cell carcinoma on scalp. We hereby present this case with the operative technique and surgical anatomy.
