We experienced a case of a 38 year old women in whom an alpha-fetoprotein producing carcinoma originated in the rectum. The patient had symptoms of hematochezia and bowel habit change, and a rectal examination revealed an ulcerative mass at the midrectum. The mass size was 6.5 cm 6 cm. The serum alpha-fetoprotein measured preoperatively was 9336 ng/ml, and the serum (carcinoembryonic antigen) was 6.4 ng/ml. The serum level of alpha-fetoprotein decreased to 830 ng/ml thirteen days after a low anterior resection. The tumor mass was a poorly differentiated adenocarcinoma. Using an immunohistochemical staining method, we detected alpha-fetoprotein producing cells in the tumor mass. During the follow up, the serum alpha-fetoprotein level began to increase continuously, and an abdomin opelvic CT scan showed a systemic, local tumor recurrence. Based on our experience with this patient and a review of the literature on the few cases previously reported, it seems that alpha-fetoprotein producing colorectal carcinamas have a tendency to produce frequent blood-borne metastasis and are associated with a poor prognosis.

Distal myopathy with rimmed vacuoles is a rare muscle disease and, so far as we know, it has not been reported in Korea as yet. This disorder is known to be inherited as autosomal recessive trait and to have no specific treatment. Hereby, we report 3 patients of distal myopathy with rimmed vacuoles in a family. The clinical characteristics of these patients were slowly progressive symmetrical muscle weakness and wasting of all 4 extremities, worse in distal legs. The pretibial muscles were involved more markedly than the calf muscles. Serum muscle enzymes were increased. The prominent EMG findings were myopathic changes, but reduced recruitment was occasionally found in some distal muscles The muscle biopsies of right biceps brachii muscle were performed in two patients, which showed the characteristic rimmed vacuoles by light microscope. Membranous whorls and randomly oriented intracytoplasmic filaments were found by electron microscope. The severity of pathological abnormalities were related to the clinical status of the patient. One had been treated with steroid(prednisolone) for several years but with no improvement.

BACKGROUND: Recent genetic analyses have shown that Miyoshi myopathy (MM) is caused by a mutation in the DYSF, which induces the dysfunction of dysferlin. We identified the deficiency of dysferlin by immunohistochemistry and Western blot in four patients with clinically diagnosed MM, and investigated the clinical and pathological characteristics of MM. METHODS: A muscle biopsy was performed in four patients who were diagnosed with MM by clinical and electrophysiological study. Immunostaining of muscle specimens for dyferlin, dystrophin, alpha, beta, gamma, sigma-sarcoglycan, beta-dystroglycan, and caveolin-3 were performed in all four patients. We analyzed the quantitative analysis for dysferlin by Western blot in three of four patients. RESULTS: All four patients showed clinical onset during adolescence or early adulthood (15-26 year old), a slowly progressive course, and a relatively high serum creatine kinase level (2240-6400 IU/L). Routine pathological studies showed non-specific myopathic changes. On immunocytochemistry, there was negative immunoreacticity for dysferlin on muscle specimens in all patients. The immunoreactivities for dystrophin, alpha, beta, gamma, sigma-sarcoglycan, beta-dystroglycan, and caveolin-3 were normal. On Western blotting, complete loss of dysferlin was noted in all three patients with MM CONCLUSIONS: Identification of isolated deficiency of dysferlin on immunocytochemistry or Western blot is important for the confirmative diagnosis of MM.

We report a 55-year-old man with chronic weakness of both legs with recently experienced nasal voice. Despite the absence of sensory symptoms, electrophysiologic studies revealed the presence of sensorimotor polyneuropathy. A sural-nerve biopsy showed remarkable reduction of large myelinated fibers with prominent remyelination. Intravenous immunoglobulin was administered due to suspected chronic demyelinating neuropathy, but had no effect. Abnormal trinucleotide-repeat expansion of the androgen receptor gene was subsequently detected in both the patient and his family. These observation indicate that prominent remyelinating features are not necessarily indicative of demyelinating neuropathy.

Neuromyelitis optica spectrum disorder (NMOSD) is an inflammatory demyelinating autoimmune disease of central nervous system characterized by relapsing attacks that target the optic nerves and spinal cord, as well as aquaporin-4 (AQP4) enriched periventricular brain regions. The area postrema (AP), located in the dorsal medulla, is the chemosensitive vomiting center and has high AQP-4 expression. The AP syndrome with unexplained hiccups, nausea, and vomiting is one of the core clinical characteristics in the NMOSD and maybe the first presenting symptom. We experienced a 25-year-old woman presented with intractable vomiting, dizziness and oscillopsia. Upbeat nystagmus detected on the bedside examination led to comprehensive neurological workups including magnetic resonance imaging, and she was diagnosed as the AP syndrome. Ten months later, she experienced a recurrence as a longitudinally extensive transverse myelitis and the diagnosis was finally compatible with NMOSD without AQP4-IgG. NMOSD, especially the AP syndrome, should be considered in any dizzy patient with intractable vomiting, and detailed neuro-otologic and neuro-ophthalmologic examinations are warranted for the correct diagnosis.

A case of diffuse cerebrospinal gliomatosis with extensive leptomeningeal spread is presented. The patient, an 18-year-old girl, was admitted due to progressive weakness and paresthesia of both legs, following rapid neuropsychiatric deterioration. An initial magnetic resonance imaging (MRI) study of the T-spine showed diffuse high signal intensities from T9 to T12 spinal cords on a T2 sagittal image and diffuse cord bulging at T1WI. This suggested an inflammatory lesion such as tuberculosis or fungal meningoencephalitis. A limited autopsy was performed. A microscopic examination revealed multifocal GFAP-positive astrocytic proliferations that were low grade astrocytoma in the cerebral leptomeninges, parietal, occipital and temporal lobes and anaplastic astrocytoma in the spinal cord and spinal leptomeninges. The high proliferative indices of the spinal lesion and aneuploidy correspond to a diagnosis of malignant astrocytoma and a rapid fatal clinical course.
