An unusual presentation of primary male genital tuberculosis.

Urogenital tuberculosis is a rare disease; however, it is the second most common location for tuberculosis after the lung. Currently, incidence of urogenital tuberculosis is increasing due to factors such as a higher prevalence of immunosuppression (especially that caused by human immunodeficiency virus infection) and drug abuse. Herein a new case of male genital primary tuberculosis is reported presenting as a scrotal tumor; the originality of this observation lies in its unusual pseudotumor form.

Changes in galectin-7 and cytokeratin-19 expression during the progression of malignancy in thyroid tumors: diagnostic and biological implications.

Galectin-7 is associated with p53-dependent onset of apoptosis and proliferation control/differentiation in keratinocyte development. It is also up-regulated in chemically induced rat mammary carcinogenesis. Because the levels of expression of galectin-7 have never been investigated in thyroid tumors (in contrast to those of galectin-1 and -3 associated with malignancy), we initiated analysis of the expression of galectin-7 in benign and malignant thyroid lesions together with that of cytokeratin-19 (CK19), a marker already demonstrated to be useful in diagnosing this kind of lesion.
