BACKGROUND Mucinous cystic neoplasms arise in the ovary and various extra-ovarian sites. While their pathogenesis remains conjectural, their similarities suggest a common pathway of development. There have been rare reports involving the mesentery as a primary tumour site. CASE PRESENTATION A cystic mass of uncertain origin was demonstrated radiologically in a 22 year old female with chronic ...

VEGF is an important angiogenic cytokine with a critical role in tumor angiogenesis. VEGF concentrations were measured using an ELISA assay, detecting VEGF165 isoform, in tumor cyst and/or ascitic fluids and in sera of 86 patients with malignant neoplasms and in 53 patients with benign ovarian neoplasms. VEGF levels were significantly elevated in the sera and cyst fluids of carcinoma patients c...

Sertoli leydig cell tumors are exceedingly uncommon tumors of the ovary accounting for less than 0.5% of all ovarian neoplasms and 1% of sex cord tumors. These tumors are functional and secrete testosterone and only rarely they are estrogenic. Hence the patients present with virilization features. Most of the tumors are unilateral and bilaterality is extremely rare. Here we report an unusual ca...

Sex cord tumors with annular tubules are known to originate from the sex cord of embryonic gonads that synthesize Sertoli cells, Leydig cells, granulosa cells, and theca cells of the ovarian stroma, while ovarian small cell carcinoma of the hypercalcemic type is a type of neuroendocrine tumor. Both these tumors are uncommon, potentially malignant neoplasms in children. We report the case of a s...

Benign neoplasms of the ovary originating from epithelial tissue are common tumors in adult women. They are, however, rarely seen in children or adolescent girls. Here the authors present a case of an ovarian mucinous cystadenoma in a premenarchal girl. To our knowledge, there are only 5 other cases reported in the literature.

CONTEXT Thecomas are benign tumors that account for less than 1% of all ovarian neoplasms. The association of ovarian thecoma with sclerosing peritonitis is rare. CASE REPORT We report the case of a 33-year-old woman, with a two-month history of increasing abdominal volume. Ultrasound showed a complex pelvic lesion and laboratory analysis detected elevated serum CA 125 levels. The patient und...

CASE SUMMARY A 15-year-old female cat was presented for investigation of progressive behavioural changes, polyuria, polydipsia and periuria. An ovarian granulosa cell tumour was identified and the cat underwent therapeutic ovariohysterectomy (OHE). The cat's clinical signs resolved, but 6 months later it was diagnosed as having an anaplastic astrocytoma and was euthanased. Serum anti-Müllerian ...

Ovarian metastasis was described the first time by Friedrich Ernst Krukenberg in 1896. Even if the historical timeline dates back to sir James Paget who had described the process in 1854 [1]. The tumor was metastazing from gastric cancer. Consequently, all metastatic ovarian cancers had been referred to as Krukenberg tumors [2]. Actually, Krukenberg tumors account for approximately 15% of malig...

Steroid cell tumors, not otherwise specified, are infrequently encountered ovarian neoplasms, which constitute <0.1% of all ovarian tumors. Most of these tumors are unilateral, and almost one-third of all cases are reportedly malignant. However, because most of these tumors are diagnosed in the early stage, and do not recur or metastasize, little is known about their response to therapies such ...
