We determined the extent of neuronal and glial cell destruction in 13 patients with herpes simplex type 1 (HSV-1) encephalitis, 15 patients with tick-borne encephalitis (TBE), and 20 noninfectious controls by analyzing the cerebrospinal fluid (CSF) concentrations of neurofilament protein (a marker of neurons, mainly axons), neuron-specific enolase (a marker of neurons, mainly somas), glial fibrillary acidic protein, and S-100 protein (markers of astrocytes). In addition, in patients with HSV-1 encephalitis CSF samples were collected serially before 7, 8-14, and 18-49 days and 3-10 months after the onset of neurological symptoms. In the acute stage of HSV-1 encephalitis we found markedly higher CSF levels of the cell damage markers than in patients with TBE. The concentration of cell damage markers in HSV-1 encephalitis decreased within 45 days after acute infection, except for neurofilament protein. The CSF concentrations of neurofilament protein increased during the second week, remained extremely high throughout the next month, and decrease thereafter. The changes in these markers of neuronal and glial destruction demonstrate the neuronal and astroglial cell damage during the first month after HSV-1 encephalitis. In contrast, most patients with TBE had signs only of slight astrogliosis, except for two patients with paresis.

Ten dogs with neuroendocrine carcinoma of the liver were selected for inclusion in the study. Clinical signs were anorexia (7), vomiting (5), polydipsia/polyuria (3), icterus (2), lethargy (2), weight loss (2), paresis (1), ataxia (1), weakness (1), collapse (1), and urinary tract infection (1). Hematologic and biochemical abnormalities included anemia (2/8), leukocytosis (4/8), high liver enzyme activity (serum alkaline phosphatase, 7/9; alanine transaminase, 7/9; aspartate transaminase, 8/9), and high total bilirubin (6/9). Grossly, the tumors were diffuse, involving all liver lobes in six dogs, and two dogs had various-sized nodules in addition to diffuse involvement. Histologically, there were eight tumors with solid or trabecular pattern (group A), one tumor with cords or rows of neoplastic cells (group B), and one tumor with multiple rosette-like structures (group C). Immunohistochemical studies revealed that all 10 neoplasms were positive for at least one of the endocrine markers used: neuron-specific enolase (NSE; 8/10), synaptophysin (5/10), and chromogranin-A (3/10). A panel of NSE, chromagranin-A, and synaptophysin detected 100% of the tumors in our series. Electron microscopy confirmed the diagnosis by the presence of intracytoplasmic neurosecretory granules in the two examined cases. Our results show that neuroendocrine markers commonly used in humans can be used for the diagnosis of hepatic neuroendocrine carcinoma in dogs, preferably a panel of synaptophysin, chromagranin-A, and NSE because chromogranin-A alone is not as useful in dogs as in humans.

The author reports herein a case of occult very small lung carcinoma with a solitary brain metastasis that is clinically diagnosed as cavernous hemangioma, with an emphasis on pathologic findings. A 48-year-old Japanese man was admitted to our hospital complaining of mild paresis of left leg. Brain CT and MRI showed a solitary tumor (2 cm) with features of cavernous hemangioma in the right temporal lobe. Tumorectomy was performed, and it was pathologically undifferentiated carcinoma. An immunohistochemical analysis reveled that the carcinoma cells were positive for four types of pancytokeratin, cytokeratin (CK) 5/6, CK7, CK18, CK19, p63, and Ki-67 (78%). They were negative for high molecular weight CK, CK14, CK20, TTF-1, PE-10, melanosome, S100 protein, EMA, vimentin, CD34, myoglobin, CEA, p53, desmin, alpha-smooth muscle actin, chromogranin, synaptophysin, CD56, neuron-specific enolase, CD68, KIT, and PDGFRA. The positive CK7 and negative CK20 suggested lung origin, and cytokeratin profiles and positive CK5/6 and p63 suggested a squamous differentiation. The pathological diagnosis was undifferentiated carcinoma with squamous differentiation probably of lung origin. Later, systemic CT, MRI and PET were performed, and they detected a small lung tumor (8 mm) in the right apex. The lung biopsy revealed an undifferentiated carcinoma with focal squamous differentiation; the immunohistochemical findings were the same as those of the brain tumor. These findings suggest that occult very small lung carcinoma can metastasize to brain and such a metastasis may mimic cavernous hemangioma radiologically. Pathologic observations using many antibodies are very useful to determine the origin and histological type in solitary brain nodule.

Gangliogliomas are composed of neoplastic glial and neuronal cells and are extremely rare tumors of the central nervous system of domestic animals. The present report describes the clinical presentation and the pathomorphological and immunophenotypical characteristics of a desmoplastic ganglioglioma in the spinal cord of a 3-year-old male western European hedgehog (Erinaceus europaeus). Clinically, the hedgehog exhibited a skin wound and therapy-resistant paresis of the left hind limb. Necropsy showed dilatation of the urinary bladder. Histologic examination of the thoracic spinal cord revealed a focally extensive infiltrative mass, which consisted of multiple nodules of smaller bipolar or oligopolar glial cells and variably sized polygonal, ganglionic, neuron-like cells embedded in variable amounts of microcystic neuropilic matrix. An area of spindle-shaped cells arranged in interwoven fascicles and surrounded by a prominent network of reticulin fibers was interpreted as desmoplastic leptomeningeal stroma. Immunohistochemistry revealed a moderate number of glial fibrillary acidic protein and S-100-positive cells and processes. In addition, the ganglionic neuron-like cells expressed neurofilament, microtubule-associated protein-2, and neuron-specific enolase. In summary, this spinal cord tumor was composed of astroglial and neuronal cellular elements, justifying the diagnosis of a desmoplastic ganglioglioma.
