Immunohistochemical Analysis of E-Cadherin, p53 and Inhibin-α Expression in Hydatidiform Mole and Hydropic Abortion.

The purpose of this study was to investigate the role of E-cadherin, p53, and inhibin-α immunostaining in the differential diagnosis of hydropic abortion (HA), partial hydatidiform mole (PHM), and complete hydatidiform mole (CHM). E-cadherin, p53, and inhibin-α protein expression patterns were investigated immunohistochemically using paraffin -embedded tissue sections from histologically diagnosed cases of HA (n = 23), PHM (n = 24), and CHM (n = 23). Expression patterns of these markers were scored semi-quantitatively according to the staining intensity, percentage of positive cells, and immunoreactivity score.

Primary cutaneous adenoid cystic carcinoma of the eyelid and literature review.

Primary cutaneous adenoid cystic carcinoma (PCACC) is a rare malignant epithelial tumor most commonly observed in the scalp and skin of the chest and originating from the palpebral portion of the lacrimal gland in the orbit. Here we describe the diagnosis and treatment of a rare case of PCACC in an eye of a 52-year-old male. The patient presented with a mass lesion of the right lower eyelid.

Expression of Cox-2 and Bcl-2 in Paget's disease of the breast.

Background: Paget's disease (PD) is a rare form of intraepithelial adenocarcinoma that involves breast and extramammarian tissues. It is often associated with ductal carcinoma in situ and/or invasive ductal cancer. Molecular pathways that play a role in development of Paget's disease are stil unclear.

Pilomatrixoma-like testicular tumour without teratomatous elements.

A 40-year-old man presented to us with infertility. During scrotal ultrasonography, a heterogeneous nodular mass was seen in the right testicle. Surprisingly, histopathological examination revealed shadow cells, which are the characteristic feature of pilomatrixomas.
