Interdisciplinary management of a viable term abdominal ectopic pregnancy

Pregnancy, Volume 2, Issue 4, July 2026.
Abstract Introduction Abdominal ectopic pregnancies are rare and associated with increased maternal morbidity and mortality. As the majority are diagnosed early in gestation, there are few reports of management of advanced abdominal ectopic pregnancies. Case A 41‐year‐old gravida 2 para 1 presented with fatigue and a known left ovarian cyst.

Unilateral malignant struma ovarii in a case of bilateral ovarian teratoma with raised CA-125 level: A rare case with treatment dilemmas

Indian Journal of Pathology and Microbiology, 2011
Struma ovarii are specialized form of mature ovarian teratoma comprised predominantly of thyroid tissue (>50%). Most of the struma ovarii are benign; rarely can they undergo malignant transformation.

Struma Ovarii: A Case of Struma Ovarii and Literature Review

Soonchunhyang Medical Science, 2014
Struma ovarii is a rare, monodermal and highly specialized teratoma, composed entirely or predominantly ( > 50%) of thyroid tissue. Presenting symptoms are not specific. Despite containing thyroid tissue, only 5% of struma ovarii have features of hyperthyroidism. Therefore, preoperative diagnosis of struma ovarii is difficult.

The Enigmatic Teratoma: Tracing Tissue Origins Through Methylation Profiling

Stem Cells International, Volume 2026, Issue 1, 2026.
Purpose Mature cystic teratomas of the ovary can contain skin, hair, muscle, and bone and are usually found in women of reproductive age. Elucidating epigenomic aberrations in these teratomas may result in a better understanding of their stepwise developmental processes and molecular bases. Methods Here, we analyzed the methylation statuses of promoter

Three Cases of Struma Ovarii Underwent Laparoscopic Surgery with Definite Preoperative Diagnosis [PDF]

, 2013
Struma ovarii is a rare neoplasm that accounts for approximately 0.3ｵ of ovarian tumors. Due to its ultrasound morphology, which is quite similar to that of malignant ovarian carcinoma, most struma ovarii cases are open operated with laparotomy rather ...
