Unusual ganglioglioma with extensive calcification and ossification.

Ganglioglioma is a slow‑growing relatively low‑grade mixed glioneuronal tumor with most cases corresponding to the WHO Grade I category. It frequently presents with seizures. The temporal lobe is the most common location followed by frontal, parietal, and occipital lobes. These generally behave in a benign fashion and have a favorable prognosis. We describe a case of a 24‑year‑old male presenting with convulsions and a calcified parieto‑occipital mass. This mass removed from the parietal lobe showed neoplastic glial and dysplastic neuronal tissue amidst extensive areas of calcification and foci of ossification. On immunohistochemistry, the glial component expressed glial fibrillary acidic protein whereas the dysplastic neuronal component expressed synaptophysin and CD34. Epithelial membrane antigen was negative and Ki‑67 showed a low proliferative index. After the surgery, the patient is free of neurological symptoms. Widespread calcification and ossification are very unusual in ganglioglioma, which prompted us to report this case

Solid variant of orbital angioleiomyoma: An unusual tumor at an unusual site.

We describe the clinicopathological features of a solid variant of orbital angioleiomyoma. A review of clinical records, diagnostic, and radiographic studies combined with histopathological evaluation with standard histochemical staining and immunohistochemistry was conducted. A 22‑year‑old male patient presented with a mass in the region of the left lacrimal gland that was gradually increasing over the past 2 years. Radiological and clinical examinations showed no signs suspicious of a malignancy and fine needle aspiration cytology was inconclusive. Therefore, an excision biopsy was performed. On histopathological examination, the picture was consistent with a benign spindle cell tumor. Immunohistochemistry showed positivity for CD 34 and CD 31 (markers for vascular endothelium). The tumor also showed positivity for smooth muscle actin and Ki‑67 proliferative index was low. Angioleiomyomas are rarely encountered in the orbit and has features seen in leiomyoma as well as some vascular tumor elements. In most cases, surgical excision is usually curative.

Aplastic anemia in an HIV infected child.

Hematologic manifestations of HIV in children are common and include anemia, neutropenia, lymphocytopenia, thrombocytopenia that may occur due to many reasons. However, aplastic anemia due to HIV infection is rare and even more so in children. Though anemia is seen with advanced disease and associated with poor prognosis it is treated with various therapeutic modalities. Our patient with aplastic anemia due to HIV infection responded to antiretroviral therapy.

Von Hippel-Lindau disease: a case report.

Von Hippel Lindau (VHL) disease is a rare autosomal dominant condition manifested by central nervous system hemangioblastoma, retinal angiomas, cysts of pancreas, kidney and epididymis, pheochromocytomas and renal cell carcinoma. We present such a case in a 45 years old male patient.
