Hemangioma are not rare tumors. They can be found in almost any of the vascular structures of the body. Hemangiomas involving the deep structures of the extremities may produce extremely difficult therapeutic problems for the orthopedic surgeon. Pigmented villonodular synovitis (PVNS) is a rare proliferative disorder that affects synovium, tendon sheath and bursa. Although the condition can present in any joint, knee joint is the most commonly affected site and only 2.5% of cases occur in foot and ankle joint. We have experienced a patient who has of foot and report an optimal method of surgical treatment. Authors report the result of hemangioma in mid-foot which arise from removal of a pigmented villonodular synovitis that has low out break rate of benign tumor in mid-foot with literature review.

혈관근육지방종은 지방, 평활근, 두꺼운 벽의 혈관이 다양한 비율로 구성된 흔하지 않은 과오종이며, 이는 결정 경화증을 동반하거나 산발적으로 발생한다. 저자들은 혈관근육지방종이 드물게 발생하는 두경부에서 발생한 귓바퀴 1예, 구개점막 2예의 혈관근육지방종을 보고하고자 한다. 병리소견상, 3예 모두에서 성숙지방조직, 불규칙한 혈관, 그리고 HMB-45와 Melan-A에 음성을 보이는 평활근육세포로 이루어진 조직소견을 보였으며, 여러군데에서 림프구 침윤이 3예 모두에서 관찰되었다. 점막피부 혈관근육지방종으로 진단하였다. 세증례 모두 결절경화증은 동반되지 않았다. 점막피부 혈관근육지방종에서는 혈관주변세포가 HMB-45와 Melan-A에서 음성을 보였으며, 이는 간이나 신장의 혈관근육지방종에서의 특징적인 양성반응과는 다른 점이었다. 간이나 신장에서 생긴 혈관근육지방종과 다른 임상병리적 특징을 비교 기술하고자 두경부에서 발생한 점막피부 혈관근육지방종 3예를 보고한다.

Central anticholinergic syndrome is defined as an absolute or relative reduction in cholinergic activity in the central nervous system and has a wide variety of manifestations. It is associated with almost any drug given during anesthesia, except neuromuscular relaxants, and treated with the cholinesterase inhibitor physostigmine. The diagnosis of central anticholinergic syndrome is often made when symptoms resolve promptly after the administration of physostigmine. We present a case of a central anticholinergic syndrome diagnosed by treatment with physostigmine, in a patient who received closure of patent foramen ovale associated with stroke.

A 39-year-old man presented with a esophageal submucosal tumor on regular check up examination. Preoperative exams showed the typical submucosal tumor as leiomyoma and operative procedure was enucleation for complete resection. Postoperative pathologic diagnosis including histologic and immunohistochemical study was compatible with plexiform schwannoma. Plexiform schwannoma is one of the least common variant of schwannoma that typically shows a plexiform or multinodular pattern. To our knowledge, there is rare case report of plexiform schwannoma originating in the esophagus and we report ore case with related literature.

Alimentary lymphoma accounts for approximately 5% of neoplasm and diffuse lesion is more common than solitary nodular form in dogs. An eleven year-old male Yorkshire terrier was examined because of nonspecific gastrointestinal symptoms such as anorexia and vomiting for 10 days. An abdominal mass was palpated, which was originated from small intestinal wall in abdominal ultrasonography. Small intestine was obstructed by hypoechoic mass and lost normal layering and measured 24.5m. After fine-needle aspiration, septic peritonitis due to intestinal rupture occurred and emergency surgery was performed. Solitary mass was found in small intestine and diagnosed as alimentary lymphoma through histopathologic examination. Conclusively, abdominal ultrasonouaphy could verify the thickened bowel, loss of wall layering and decrease of motility and percutaneous ultrasound-guided fine-needle aspiration is considered as useful diagnostic technique, especially in nodular form of alimentary lymphoma.

Osteochondromas are benign bone tumors typically found in the metaphyseal region of long bones. These tumors are often asymptomatic and detected incidentally. However, their occurrence in atypical sites such as the talus can pose significant diagnostic and treatment challenges. This report describes a rare case of osteochondroma of the medial tubercle of the talus, which is an unprecedented location based on a review of relevant literature. A 28-year-old male presented with worsening medial ankle pain and limping. Imaging revealed a lesion consistent with osteochondroma contributing to medial ankle impingement syndrome. Uniquely, this case also featured a coinciding gout attack in the ankle joint. Surgical removal of the lesion resulted in significant symptom relief and functional improvement. This case underscores the need to consider rare diagnoses, such as talar osteochondroma, when presented with persistent medial ankle pain and highlights the potential presence of concurrent conditions, such as gout.

We report here a case of pulmonary benign metastasizing leiomyoma from the uterus in a 45 year old woman. The patient presented for investigation of multiple pulmonary nodules on a routine chest roentgenogram. The patient had undergone uterine myomectomy due to uterine leiomyoma 10 years earlier. We performed thoracoscopic wedge resection for definitive diagnosis. Histologically, spindle shaped smooth muscle cells appeared between collagen stroma, histology similar to that seen in uterine myoma. The tumor tissue tested positive for estrogen and progesterone receptors. The pathological findings were consistent with benign metastasizing leiomyoma. The patient was in pre-menopause. She received no specific treatment for lung tumors, and we did not found any changes in the lesions after one year follow up without any medication.

Neurocutaneous melanosis is a rare congenital syndrome characterized by the presence of large or multiple congenital melanocytic nevi and benign pigment cell tumors of the leptomeninges. Neurocutaneous melanosis is thought to represent an error in the morphogenesis of embryonal neuroectoderm. We experienced a neonate who presented with giant, dark colored pigmented nevi covering chest, abdomen, neck and arms, with satellite lesions. Magnetic resonance image showed a nodular hyperintense lesion in the amygdala of the right temporal lobe, and T1-weighted images showed hyperintensities in the adjacent leptomeninges. We report a rare case of neurocutaneous melanosis with a brief review of related literature.

Calcifying aponeurotic fibroma is a benign, aggressive fibrous tumor seen in childhood or adolescence that most commonly affects the palm. We report our experience in treating calcifying aponeurotic fibroma in the hand of fifteen-year-old boy. He was presented with a recurrent mass in hypothenar area of his left hand. He had a history of local excision of the mass 7 years ago in local clinic. The palpable mass was hard, tender and movable. The simple X-ray revealed multifocally scattered microcalcifications in the mass. The excised mass showed the features of dense fibrotic soft tissue tumor with multiple small whitish calcifications. The microscopic sections showed a lobulated and a poorly circumscribed proliferation of dense fibrous tissue, containing islands of metaplastic chondroid differentiation with prominent calcification. The recommended treatment of this lesion is wide excision allowing for sparing of functional or vital structures, but high recurrence rate as this case has been reported to be more than 50 percent.
