    ABSTRACT: Adenoid cystic carcinoma is a relatively rare epithelial tumor of the salivary glands accounting for about 5-10% of all salivary gland neoplasms. Approximately, 31% of salivary gland neoplasms affect minor salivary glands particularly the palate. It involves tongue in only 19.8% of cases and even rarely the dorsum of the tongue. We report such a rare case that affected dorsum of the tongue in a 45-year-old-female patient.

    ABSTRACT: The primary brain tumors are the second most common cause of death due to malignancies in children. This study was done to analyze the histological spectrum of primary brain tumors in children and also to find out the expression of p53 and Ki67 in some of the common pediatric brain tumors. This study was done over a period of 2.5 years. The patients were followed up until 6 months to determine the outcome. We examined H and E sections from 61 pediatric brain tumors and also performed immunohistochemical stains with p53 and Ki67 on 52 of these samples. Of the 61 cases of pediatric brain tumors the commonest were pilocytic astrocytomas and medulloblastomas both constituting 22.9% of total cases, followed by high grade gliomas, that is, anaplastic astrocytoma and glioblastoma taken together (14.7%), diffuse astrocytomas (11.4%), ependymomas (8.1%), and oligodendrogliomas (4.9%). Other cases comprised craniopharyngiomas, astroblastomas, and gangliocytoma. The mean age of presentation was 9.3 years, male children being more commonly affected. Ki67 labeling index (LI) and p53 expression in pilocytic astrocytomas and diffuse astrocytomas were significantly lower than that of high-grade astrocytomas. However, there was no significant difference of expression of these two antigens in pilocytic astrocytomas and diffuse astrocytomas. It was found that Ki67 LI was a better marker for distinguishing between grades of astrocytoma than p53 (P=0.000 and P=0.002, respectively). The survival in cases of pilocytic astrocytomas was far better than high-grade gliomas. However, there was no significant difference in survival between pilocytic astrocytoma and diffuse infiltrating astrocytoma. There was significant positive correlation between expression of p53 and Ki67 LI in cases of medulloblastomas. Both p53 (P=0.002) and Ki67 LI (P=0.000) taken individually correlated well with survival in these cases. Also, Ki67 LI is better predictor of outcome than p53. From this study, it can be concluded that Ki67 and p53 score correlated well with the grade of astrocytoma; however, Ki67 is a better marker for differentiating between the grades of astrocytoma than p53. Also, Ki67 LI is a better prognostic factor than p53 in case of medulloblastomas.

    ABSTRACT: Primary pulmonary neoplasms are uncommon in children and represent a wide spectrum of pathology from benign to malignant. They are quite different in their histopathologic distribution from that of adults. This study was done to analyze the histopathologic spectrum of primary lung tumors in children. All the resected specimens of lung in children over a period of 5 years were studied and only the cases of primary pulmonary neoplasms were further analyzed. There were two cases of inflammatory myofibroblastic tumor. The patients were boys aged 10 and 12 years, respectively. One case of bronchial carcinoid was diagnosed in a boy of 12 years. There were one case each of pleuropulmonary blastoma (PPB) in a girl of 9 years and pulmonary blastoma (PB) in a girl of 2 years of age. In our study, the two cases of inflammatory myofibroblastic tumor had excellent prognosis. However, the cases of PPB and PB were both associated with poor clinical outcome, whereas the case of bronchial carcinoid has been doing well on follow-up.

    ABSTRACT: Leydig cell tumors (LCTs) are rare testicular tumors. They constitute 1-3% of all testicular tumors. We report two cases of LCT, one benign and the other one malignant, representing both ends of the spectrum. The case of benign LCT presented with infertility and was found to have azoospermia, and subsequently underwent orchidectomy. Histopathologic examination revealed the presence of a benign LCT. Postoperative recovery was uneventful. The sperm count improved subsequently, and a year later, he fathered a child. The case of malignant LCT was seen in another 47 year old male who presented with cough. On examination, a testicular swelling was found, and after orchidectomy, he was diagnosed to have malignant LCT on histopathologic examination.
