Esophageal squamous cell carcinoma (ESCC) is one of the aggressive malignancies and mechanisms underlying its pathogenesis remain unclear. Cyclooxygenase-2 (COX-2) enzyme system plays a crucial role in many gastrointestinal malignancies and is an important regulator of cell growth, proliferation, apoptosis, differentiation and transformation. More precise outcome of COX-2 in ESCC is less investigated. In this study we investigated the risk factors of ESCC and expression of COX-2 in Carcinoma in situ (CIS) and ESCC compared to normal esophageal mucosa. ESCC relationship to clinico-pathological parameters using immunohistochemistry was also part of this investigation. Current study was conducted in the Institute of …

A 45 year old woman presented with right sided ovarian mass with multiple omental deposits and liver metastases. The right ovary was enlarged and showed a partly cystic partly solid cut surface. Histological picture showed clear cell carcinoma with areas of mucinous cystadenoma and endometriosis. Clear cell carcinoma is known to be associated with endometriosis. To the best of author's knowledge, it's association with mucinous cystadenoma has been described only once in the literature, where clear cell carcinoma was shown to be associated with mucinous cystadenoma without any evidence of endometriosis.
