Heterotopic pancreas (HP) is a rare entity which is defined as the presence of pancreatic tissue lacking anatomical and vascular continuity with the pancreas. It is most commonly found along foregut derivatives, such as the stomach, duodenum, and jejunum. It is frequently encountered incidentally in asymptomatic patients, and symptomatic patients are rare and do not exhibit any specific symptom...

To date, no reports have presented radiculopathy secondary to heterotopic ossification following lumbar total disc arthroplasty. The authors present a previously unpublished complication of lumbar total disk arthroplasty (TDA) secondary to heterotopic ossification (HO) in the spinal canal, and they propose a modification to the McAfee classification of HO. The patient had undergone an L5/S1 lum...

The most widely used radiologic classification system for heterotopic ossification after total hip arthroplasty (THA) is the Brooker scale. In 2002, Della Valle et al proposed a modified rating system for heterotopic ossification to increase intraobserver reliability and interobserver agreement. To date, no study comparing these 2 classification systems has been conducted. Moreover, these studi...

CONTEXT Heterotopic pancreas is defined as the presence of pancreatic tissue, outside its usual location, which lacks anatomical and vascular continuity with the pancreas proper. Despite the development of modern diagnostic procedures, it is still difficult to differentiate heterotopic pancreas from benign or malignant tumors and other tumor-like lesions. Frozen examination of mucinous lesions ...

CONTEXT Heterotopic pancreas is defined as ectopic pancreatic tissue without vascular or anatomic continuity with the normal pancreas. The spleen is a rare site of origin. This case report describes a patient with a malignant insulinoma which originated from an intrasplenic heterotopic pancreas. CASE REPORT A 46-year-old man with three previous episodes of neuroglucopenic and adrenergic sympt...

It is not known whether surgical denervation leads to increased beta-receptor sensitivity after human cardiac transplantation. We assessed cardiac beta-receptor sensitivity by studying the heart rate response to isoprenaline of the denervated donor heart as compared with the innervated recipient heart in eight patients who underwent heterotopic cardiac transplantation and in six patients with o...

Heterotopic pancreas is a rare congenital disorder characterized by the presence of normal pancreatic tissue located outside the pancreas. The most common locations include the duodenum, stomach, and jejunum. Most cases of heterotopic pancreas are asymptomatic. However, the development of clinical symptoms depends on the size, location and pathological changes similar to those observed in case ...

BACKGROUND Heterotopic interstitial pregnancy is a rare variant of heterotopic pregnancies, and it poses challenges in treating the heterotopic pregnancy and preserving the intrauterine pregnancy. However, there is no clear consensus regarding the optimal management. The aim of this study was to investigate the pregnancy outcomes of women diagnosed with heterotopic interstitial pregnancy. MET...

Using a previously described murine heterotopic corneal allograft model, we examined the roles of delayed-type hypersensitivity (DTH) and cytotoxic T lymphocytes (CTL) in corneal allograft rejection. We have previously shown that normal C57BL/6 mice consistently reject heterotopic corneal allografts within 14 days of grafting. These hosts develop antigen-specific CTL responses but no evidence o...

Heterotopic pancreas is most frequently seen in the duodenum, lacking the normal anatomic and vascular structure of the pancreas (1). The preoperative diagnosis is usually complex and challenging. Treatment of cystic dystrophia of a heterotopic pancreas (CDHP) remains controversial. In this letter, we are presenting a case of giant CDHP that was diagnosed within the preoperative stage and treat...
