Heterotopic ossification is the formation of extra-skeletal bone in the muscle and soft tissues, and an osteoma is a benign bone-forming tumor composed of compact or mature trabecular bone limited almost exclusively to the craniofacial bones. This paper reports an extremely rare case of heterotopic ossification mimicking an osteoma that occurred independently at the plantar side of the medial sesamoid bone. The patient was a 46-year-old male with a three-month history of pain and a hard mass on the plantar aspect of the left forefoot sole. After excising the lesion, the patient's symptoms were relieved, and no pain or complications occurred. This paper discusses this exceedingly rare case of heterotopic ossification around the medial sesamoid bone with a review of the relevant literature.

Heterotopic bone formation in abdominal incisions is a recognized but uncommon sequela of abdominal surgery. On the other hand, the formation of ectopic bone is a well-recognized complication following arthroplasty of the hip. Heterotopic ossification of midline abdominal incision scars is a subtype of myositis ossificans traumatica. Ectopic bone formation of midline abdominal incisions may cause regional pain or discomfort in the patient after surgery. If symptomatic, treatment is complete excision with primary closure. Radiologically, it is important to distinguish this benign entity from postoperative complications. We report a 69-year-old male who underwent exploratory laparotomy for traumatic small bowel perforation. A segment of abnormal hard tissue was found in the abdominal wall. Heterotopic ossification may occur at various sites and is a recognized but infrequent sequela of exploratory laparotomy. This case highlights clinical and etiological features of this finding.

The incidence of heterotopic ossification (HO) was reported to be higher in combat-injured patients than in civilian trauma patients. HO is often considered a possible cause of residual limbs pain in amputee. Here, we report the case of a 21-year-old male, who underwent a traumatic right transfemoral and left transtibial amputation with two segments of painful HO around his left amputation site. We report the effect of extracorporeal shock wave therapy (ESWT) on size and pain associated with HO. After ESWT, the visual analog scale score decreased from 5~6 to 0~1 and the size of two masses decreased from 13.1 × 6.7 mm and 12.5 mm to 11.9 × 4.7 mm and 12.2 mm, respectively. To the best of our knowledge, this is the first case that has reported on the treatment of HO using ESWT for a traumatic transtibial amputation patient. The case suggests that ESWT could serve as a complementary treatment for HO in traumatic amputation patient.

Heterotopic ossification is formation of bone in atypical extra-skeletal tissues and usually occurs spontaneously or following neurologic injury with unknown cause. We report a 46-year-old female with right shoulder pain and restricted range of motion (ROM) for 3 months without history of trauma. Magnetic resonance imaging (MRI) showed a lesion within the rotator cuff supraglenoid. Excisional biopsy from a previous institution revealed a heterotopic ossificans (HO). Following repeat MRI and bone scan, histopathology from arthroscopic resection confirmed an HO. The patient demonstrated improved pain and ROM at follow-up. Idiopathic HO rarely occurs in the shoulder joint, and resection of HO should be delayed until maturation of the lesion to avoid recurrence. The current case showed that arthroscopic HO resection provides an excellent surgical view to ensure complete lesion removal and minimize soft tissue damage at the supraglenoid area. Furthermore, the minimally invasive procedure of arthroscopy may reduce rehabilitation time and facilitate early return to work.

Objectives : The present study was investigated the effect and pathway of heterotopic electroacupuncture (EA) on pain induced by formalin in rats. Methods : Acupoints in the right forepaws, $HT_7$ and $PC_7$, were stimulated with 3 mA, 2 ms, and 10 Hz before subcutaneously formalin injection (5%, $50{\mu}l$) to the left hind paw. Moreover, it was investigated whether the dorsolateral funiculus (DLF), as known to the descending inhibition, mediates analgesia of the heterotopic EA, and an administration of naltrexone blocks the effect of EA. Results : In the immunohistochemistry of cFos-like protein (cFL), there were inhibitory effects of EA on the increased expression of cFL in the lumbar spinal dorsal horn neurons following formalin injection. Especially, EA inhibited the expression of cFL on the superficial laminae than that on the deep laminae at 1 hr after, but that on the deep laminae than that on the superficial laminae at 2 hr after. Also, EA suppressed the increased expression of nitric oxide (NO) and neuronal nitric oxide synthase (nNOS) in the lumbosacral spinal cord after formalin injection, but not Sham-EA. Suppressed expressions of cFL, NO and nNOS in the spinal cord were eliminated after transection of the ipsilateral DLF at $T_{10}{\sim}T_{11}$ levels. However, pretreatment of naltrexone could not prevent the suppressive expressions of cFL, NO and nNOS at the spinal cord. Conclusions : These results suggest that the analgesia of heterotopic EA may be modulated through the DLF constituting the descending inhibition.

Heterotopic ossification is often complicated in patients with brain injury. It occurs in the connective tissue of skeletal muscle close to a joint, especially most highly in the hip joint. This study have reported a case of heterotopic ossification in hypoxic brain damage patient due to cardiac attack. Binso-san is known by medication on arthritis. It has an effect on pain control or reduce of swelling in the joints. This study suggest that Binso-san has an improving effect on hip joint affected by Heterotopic ossification.

We report the case of a heterotopic ossification in the subscapularis muscle. A 30-year-old woman was diagnosed as a heterotopic ossification in the right subscapularis muscle. X-rays, a CT scan and a MRI showed bone-like lesions in the muscle. The location of the ossification was both inferior and anterior to the joint. The mass nearly bridged between the proximal humerus and the inferior portion of the coracoid process. Symptoms did not respond to rest, NSAIDs for 3 months and to stretching exercises treatment for 6 months. Excision and biopsy was performed through deltopectoral approach. Disodium Etidronate was administered during the postoperative period. She regained normal range of motion postoperatively and improved in the shoulder pain after performing strengthening exercises with Therabands. We think that a cause of limitation of the shoulder was impingement between the mass and the coracoid process, and that another cause was adhesion between the mass and the joint capsule. We conclude that excision and postoperative rehabilitation exercises are good methods for a heterotopic ossification in the subscapularis muscle for those that are nonresponsive to nonoperative treatments.

치아의 통증은 구강안면부에서 가장 흔하게 발생하는 통증이다. 대부분의 치아 통증은 치수 및 치주조직의 병적인 변화로 인한 치성 통증이지만, 구강안면부의 다른 구조물의 병적 변화 또는 다른 질병 등에 의한 통증이 치아의 통증으로 나타나는 경우도 흔히 존재하며, 이러한 통증을 '비치성치통'이라고 한다. 비치성치통은 통증의 발현 부위와 통증의 원인 부위가 일치하는 원발성 통증이 아니라, 통증의 발현 부위와 통증의 원인 부위가 동일하지 않은 이소성 통증에 속하므로 통증의 원인을 찾아 치료해야만 개선될 수 있다. 비치성 치통을 유발하는 요인에는 신경병증성 통증, 부비동질환 기원의 통증, 근막통증, 신경혈관성 통증, 심장질환, 두개 및 구강안면부 종양, 중이염 등에 의한 전이통, 심인성 원인 등이 있다. 이러한 다양한 원인에 의한 통증이 치아부위에 나타나는 경우 치아 및 치주조직에 대한 임상 및 방사선 사진 검사 상 병적인 소견이 관찰되지 않음에도 불구하고, 치아통증과 유사한 임상적 증상을 나타낼 수 있다. 그러므로, 임상가들은 비치성 치통을 유발할 수 있는 원인 및 관련 증상들에 대하여 잘 알고 있어야 하며, 세심한 병력 청취, 치아 관련 구조물 및 그 외의 구조물에 대한 정확한 임상 검사를 통해 치성 통증과 감별할 수 있어야 한다. 본 증례 보고에서는, 치아 통증과 유사한 양상을 보이는 비치성 치통으로 내원한 환자의 진단 및 치료에 관한 증례를 통해, 비치성 치통에 대한 고찰 및 진단과 치료시의 고려 사항에 대하여 살펴보고자 한다.

병합임신은 두 개의 수정란이 자궁강 내와 자궁강 외에 동시에 착상되어 임신되는 것을 말한다. 그 예가 드물어 자연발생빈도는 약 30,000건의 임신 중 1명으로 나타나지만, 최근에는 불임환자의 체외 수정을 위한 배란 유도제의 사용이나 기타 생식 보조술의 발달, 골반내 염증, 난관수술로 인해 증가하고 있다. 병합임신은 조기 진단이 어려워 이에 따른 모성 사망률, 이환율이 높아지므로, 진단에 있어서 신중함이 중요하다. 저자들은 경찰병원에서 자연 생리주기에서 7주간의 무월경과 심한 하복부 통증을 주소로 내원한 29세 여환에서 발견된 좌측 난관임신과 자궁강 내 임신이 공존하는 병합임신을 간단한 문헌 고찰과 함께 보고하는 바이다.

Heterotopic pancreas (HP) is defined as pancreatic tissue lacking anatomic and vascular continuity with the main body of the pancreas. Most are asymptomatic, but can cause ulcer, bleeding, intussusception, and mechanical obstruction. Herein, we presented one case of HP presented as duodenal tumor causing duodenal obstruction. A 7-year-old girl visited the emergency room for abdominal pain with vomiting for 24 hours. Computed tomography and upper gastrointestinal series revealed a polypoid mass with short stalk in the 2nd portion of duodenum. We attempted an endoscopic removal. However, the lumen was nearly obstructed by the mass and the stalk was too broad and hard to excise. The mass was surgically removed via duodenotomy. It was confirmed as a HP with ductal and acini components (type 2 by Heinrich classification). Postoperatively, the patient has been well without any complication and recurrence.
