Hyaline cell-rich chondroid syringoma of the finger

A mixed tumor is a neoplasm that has microscopic features of both epithelial and mesenchymal differentiation. Such mixed tumors are known as pleomorphic adenomas in the salivary glands, and their cutaneous counterparts are called chondroid syringomas. These tumors commonly occur in the head and neck region of middle-aged men. Hyaline cell-rich chondroid syringoma is a rare benign variant of chondroid syringoma composed of cells with eosinophilic hyaline cytoplasm and plasmacytoid features, the origin of which remains elusive. Although very few cases have been reported in literature, it is important to be aware of this entity so as to avoid misdiagnosis on histopathological examination. In this report we present a case of hyaline cell-rich chondroid syringoma occurring in the finger.

Ovarian tumours: a study of 282 cases

Histologically 282 ovarian tumours were studied, of these 212 (75.2%) were benign, 8 (2.8%) of borderline malignancy and 62 (21.9%) were malignant. The tumours were classified according to WHO classification. Epithelial tumours were the commonest variety constituting 70.9% of all the ovarian tumours followed by germ cell tumours (21.2%), sex cord stromal tumours (6.7%) and metastatic tumours (0.7%). Among the individual tumours, serous tumours (42.9%) were the commonest, followed by mucinous tumours (25.5%), teratomas (17%), granulosa cell tumours (6.7%), dysgerminomas (2.48%) and endodermal sinus tumours (1.77%). Two cases (0.7%) of endometrioid carcinomas and one case (0.35%) of clear cell carcinoma were encountered. Ovarian tumours were found to occur in the age range of 8 months to 74 years. Peak incidence was between 21 and 40 years age group.
