Motor weakness is one of the neurological complication that can occur after aneurysmal subarachnoid hemorrhage (SAH); incidence of motor weakness of 14~29% has been reported. Detailed information on the pathogenic mechanism of motor weakness is essential for brain rehabilitation because it enables estimation of the severity of injury, establishment of scientific rehabilitative strategies, and prediction of motor outcomes by clinicians. However, the exact pathogenic mechanisms of motor weakness following aneurysmal SAH have not been clearly elucidated. In this article, 14 previous studies on pathogenic mechanisms in patients with aneurysmal SAH were reviewed according to the location of the lesion (cerebral cortex, brainstem, spinal cord, and peripheral nerve). The following pathogenic mechanisms have been suggested: vasospasm, cerebral ischemia, hydrocephalus, compression of cerebral cortex, neural injury, spinal cord infarction, and radiculo-neuropathy. Considering the high incidence of aneurysmal SAH and motor weakness following aneurysmal SAH, we believe that the pathogenic mechanisms of motor weakness have been relatively understudied. More effort should be taken to investigate this important topic.

Neoplasms showing both carcinomatous and sarcomatous features are well established, and have been reported in practically every organ where carcinoma can occur. But the difference in terminology and difficulties in histopathologic interpretation have hampered adequate understanding of these neoplasms. We report a case of carcinosarcoma in the recurrent form of serous cystadenocarcinoma of the ovary. The patient was a 64-year-old female who underwent total hysterectomy and bilateral salpingoophorectomy three years ago, due to perforated papillary serous cysta denocarcinoma of the right ovary. Recurrent pelvic masses contained both carcinomatous and sarcomatous components. Morphological transition between carcinomatous and sarcomatous components, and epithelial characteristics in the sarcomatous component by immunohistochemistry were recognized. We postulate the histopathogenetic mechanism based on the phenotypic conversion of carcinoma into sarcoma in the carcinosarcoma.

A case of an ovarian mucinous cystadenocarcinoma with mural nodules of anaplastic carcinoma is reported. The patient was a 46-year-old female with a right ovarian cystic mass and underwent a total abdominal hysterectomy with bilateral salpingo-oophorectomy. The patient died of the disease in five months. Macroscopically, the right ovarian cyst wall contained numerous well-demarcated mural nodules. Histologically, the cysts were mucinous cystadenocarcinoma, and the nodules were composed of sarcoma-like spindle and polygonal cells with atypia and numerous mitoses. Spindle cells in the mural nodule showed epithelial characteristics by electron microscopy and immunohistochemistry. This case supports an epithelial origin of the mural nodule of anaplastic carcinoma in ovarian mucinous tumors.

A 26-year-old man presented with a bluish speckled patch on the dorsum of the left hand. It had apperaed at birth as a bluish spot. Since adolescence the lesion extended and at the time of visiting hospital it covered the most part of the dorsum of the left hand and even some palmar aspect. The histopathological and ultrastructural examination revealed numerous dermal melanocytes, mainly in the upper dermis. Clinically and pathologically, the patient was diagnosed as having dermal melanocyte hamartoma, a distinct type of dermal melanocytosis.
