A rare case report of squamous-cell carcinoma arising from mature cystic teratoma of ovary.

The most frequent ovarian germ cell tumors are mature cystic teratomas (MCTs), composing 10-25% of all ovarian neoplasms. MCTs have the potential of undergoing malignant transformation, typically in postmenopausal women, with a frequency of 0.17-3%, with squamous cell carcinoma being the most common malignant tumor arising from MCT.

Metastatic neoplasms of the ovaries: a clinicopathological study of 97 cases.

Objective: To present the clinicopathological features of metastatic ovarian neoplasms with emphasis in the diagnostic challenge.

Methods: This is a retrospective study including 97 patients with pathological diagnosis of metastatic ovarian neoplasms, examined during the decade 2000-2009. The gross, microscopical and immunohistochemical characteristics as well as the clinical data (age of the patients, origin of the neoplasm, symptoms, treatment options) and 5-year survival rates were examined.

"Solitary" necrotic nodule of the liver: an enigmatic entity mimicking malignancy.

Aim: The aim of the study is to further investigate the clinicopathological features of solitary necrotic nodules.

Material And Methods: Twenty-three archived cases of solitary necrotic nodule of the liver, which were preoperatively misdiagnosed as liver metastases were studied. The pathological findings were correlated with the clinical data of the patients.
