Hyalinizing clear cell carcinoma of the salivary gland is a rare neoplasm, accounting for only less than 1% of malignancies arising from the salivary gland. It is molecularly defined by the expression of the EWSR-ATF1 fusion oncogene. To date, there has been no previous studies published yet in the Philippines regarding the existence of this tumor. In this paper, we present a case of a 70-year-old elderly female who had a 10-year history of a gradually enlarging left lateral neck mass. Histopathologic examination showed a tumor arranged of cords, nests, and trabeculae of monomorphic round cells with abundant clear to lightly eosinophilic cytoplasm surrounded by thick hyalinized collagen bundles. Immunohistochemistry and molecular studies were done which revealed a positive p63 staining, negative SMA and S100, and an EWSR1 rearrangement in Fluorescence in situ hybridization (FISH), thus, confirming the diagnosis.

This paper documents the utility of ultrasound-guided tru-cut biopsy in the diagnosis and subsequent management of a case of occult breast carcinoma presenting with multiple distant metastases in the absence of a primary breast lesion. She was initially diagnosed as primary ovarian malignancy with metastatic disease and subsequently underwent transvaginal ultrasound-guided tru-cut biopsy of the right ovarian mass. Histologic and immunohistochemical studies were consistent with a metastatic adenocarcinoma of breast origin. The patient underwent chemotherapy for primary breast carcinoma and has responded well.

Basosquamous carcinoma, a variant of basal cell carcinoma, is rather rare with an incidence of only 1 – 2% of cases. 1, 2 It has a predilection for the head and neck region (95.6%) with primary sites including the nasal, auricular and periocular area with the neck involved in only 1.1%.1 Unlike typical basal cell carcinoma, basosquamous carcinoma behaves more aggressively with a higher tendency for metastasis and recurrence. Its rarity translates to a lack of management guidelines. Because of its pattern of growth and relative aggressiveness, treatment plans must be well laid; recurrence resulting from poor planning may lead to a worse outcome and poorer prognosis.

To pursue a desirable format for the pathological diagnosis of liver cirrhosis, the authors attempted to classify 369 biopsy-proven cirrhosis on the basis of etiology and made effort to find out the morphological characteristics of each category. About 735 of total cases were HBsAg seropositive postnecrotic cirrhosis. Alcholic cirrhosis ws the second most frequent type, although accounted only 6.8%. In about 15%, the etiology was not known. Excluding the congenital biliary atresia, chronic biliary obstruction appeared to be a rare cause of cirrhosis among these biopsied cases. Of the HBsAg positive postnecrotic cirrhosis, the eAg seropositive cases tended to be micronodular and to show a higher necroinflammatory activity, in contrast to eAg seronegative cases and those complicated by hepatocellular carcinoma (HCC), suggesting that the loss of eAg is followed by a decrease of the destructive activity, active regeneration of hepatocytes and finally the development of HCC. alcoholic cirrhosis was micronodular in 64% and revealed histologic evidences of alcoholic liver disease in most cases. The results indicate that etiological diagnosis can be made in most cases of cirrhosis by the morphological characteristics and the precise clinical informations, including those on the NANB virus and the inborn error of metabolism, and that the pathological diagnosis should be more comprehensive, implicating the etiology, the nodular size and the necroinflammatory activity.
