Heterotopic pancreas is defined as the presence of pancreatic tissue, outside its usual location, which lacks anatomical and vascular continuity with the pancreas proper. The heterotopic pancreas can accompany various lesions of the pancreas, such as acute pancreatitis, epithelial cyst, pancreatic pseudocyst, and exocrine and endocrine tumors. Tumor-like lesions arising from heterotopic pancrea...

Heterotopic ossification (HO) is the pathologic formation of bone separate from the normal skeleton. Although several models exist for studying HO, an understanding of the common in vitro properties of cells isolated from these models is lacking. We studied three separate animal models of HO including two models of trauma-induced HO and one model of genetic HO, and human HO specimens, to charac...

Cryopreservation of ovarian tissue has been proposed for storing gametes of young patients at high risk of premature ovarian failure. Autotransplantation has recently provided some promising results and is still the unique option to restore ovarian function from cryopreserved ovarian tissue in humans. In this article, we analyse data from the combined orthotopic and heterotopic transplantation ...

It is acknowledged that the uvula’s “structure’s function appears in the literature in only the briefest fashion”. It has also been declared that “Disorders of the palatal uvula are one of the least highlighted areas of medical literature”. Therefore, we present a most rare case of heterotropic thyroid tissue found in this organ in Nigeria. It is an addition to the worldwide appreciation of thi...

BACKGROUND Idiopathic arthrofibrosis occurs in 3-4% of patients who undergo total knee arthroplasty (TKA). However, little is known about the cellular or molecular changes involved in the onset or progression of this condition. To classify the histomorphologic changes and evaluate potential contributing factors, periarticular tissues from the knees of patients with arthrofibrosis were analyzed ...

To investigate further the factors involved in the development of cerebral cortical circuitry, we examined the organization of corticocortical connections of heterotopic grafts of fetal cortex placed into neonatal rat cortices. Presumptive perirhinal or sensorimotor areas of the cerebral wall were removed as slabs from embryonic day 12 (E12), E13, or E14 rats and transplanted heterotopically in...

The occurrence, in the subarachnoid space, of heterotopic nests composed of neuroglial tissue has been recognized since the original report, in 1907, of a case by Wolbach (1) whose description of heterotopic glial nests was substantiated by O. T. Bailey (2) in 1936. The essential anatomic features of the discrete structures reported by these authors are: 1) they are composed of mature astrocyte...

Developmental aberrations of the thyroid gland are common. It develops from pharyngeal endoderm, appearing in the fourth embryonic week as a hollow median outgrowth from the floor of the primitive pharynx at the site of the future foramen caecum of the tongue. The thyroid rudiment lies in intimate relationship with the aortic sac, being in direct contact with its endothelium. The rudiment grows...
