Extraskeletal bone formations within the soft tissues can be the presentation of benign self-limited ossifying processes such as heterotopic ossification (HO) or malignant neoplasms such as extraskeletal osteosarcomas. Depending on the involved tissue, a number of synonymous terms have been established to describe these lesions. Myositis ossificans (MO) is the most common and refers to benign b...

Background and Aim: Ovarian torsion is one of the rare causes of emergency surgeries during pregnancy. Heterotopic pregnancy is a rare type of pregnancy characterized by embryo implantation in two different locations. occurence of these two complications at the same time is a very rare condition. In this study, we present a rare case of heterotopic pregnancy accompanied by ovarian torsion. Pat...

PURPOSE verify the cytological and histological aspects of the regeneration of fragments of autologous and heterotopic spleen implanted in peritoneal cavity and subcutaneous screen in Wistar albino rats. METHODS forty four Wistar rats were assigned to one of two groups A (n=22) and B (n=22), which received their implants in subcutaneous screen and peritoneal cavity, respectively, under anesth...

Heterotopic pregnancy is rare under natural circumstance (conception). We report the first case of heterotopic pregnancy in spontaneous conception with four previous caesarean sections and ruptured tubal ectopic with resultant successful normal intra-uterine pregnancy delivered at term after salpingectomy. A 32-year-old gravida 5 para 4+0 with 3 living children, with 4 previous caesarean sectio...

Pulmonary adenocarcinoma is a common malignancy that often involves calcification; however, bone formation in primary lung adenocarcinoma is extremely rare. In ten cases of primary pulmonary adenocarcinoma with heterotopic ossification, we detected immunoreactivity against TGF-beta1, osteopontin, osteocalcin and Runx2 in the fibroblastic stroma and tumor cells within the area of ossification. O...

Heterotopic pregnancy refers to the presence of simultaneous pregnancies at two different implantation sites. Heterotopic pregnancy is rare, estimated to occur in 1 per 30,000 pregnancies. We report a case of a 27-year-old woman presented to the emergency department with the diagnosis of ruptured ectopic pregnancy. Careful ultrasound assessment indicated the diagnosis of heterotopic pregnancy. ...

Heterotopic pregnancy is the presence of an intrauterine pregnancy and an extrauterine (ectopic) pregnancy. Spontaneous heterotopic pregnancy is rare with an incidence of 1:30,000 but the prevalence is increasedwith assisted reproductive technology (ART). Delayed diagnosis of heterotopic pregnancy is not uncommon, often presenting with signs ofruptured extrauterine pregnancy. This case report d...

Heterotopic ossification is defined as bone formation in nonosseous tissues. Heterotopic ossification usually occurs in trauma such as fractures and surgical procedures. Heterotopic ossification of the hip, for example, is the most common complication of total hip arthroplasty (THA). It can occur in as many as 53% of THA patients, and it causes postoperative disability from pain and limited ran...
