A captive female capybara (Hydrochoerus hydrochaeris) of unknown age discharged a bloody mass from the vaginal region. A histopathology examination revealed the mass to be a reproductive leiomyosarcoma, and an ovariohysterectomy was performed. The histopathology examination confirmed that the excised tissue was a uterine leiomyosarcoma. The purpose of this report is to describe clinical history and histopathological diagnosis of leiomyosarcoma in capybaras. This report is novel because it describes the first diagnosis of uterine leiomyosarcoma in a capybara. Since clinical data about capybaras are rare, this case report will help to diagnosis and treat reproductive diseases of this species.

평활근육종은 중간엽세포 기원의 평활근 분화를 보이는 연부조직육종으로 소아에서는 전체 연부조직육종의 2% 이하의 발생률을 보이는 매우 드문 질환이다. 특히 흉벽의 평활근육종은 더욱 드물다. 저자들은 우연히 발견된 흉벽 종양을 방사선학적 검사로 골연골종으로 추측하여 완전절제술을 실시하였고, 조직검사 결과 저등급 평활근육종으로 진단된 1례가 있어 보고하는 바이다.

평활근육종은 주로 자궁근육층, 후복막강에서 발생하는 악성질환으로 일차성으로 부신에서 발생하는 경우는 매우 드물다. 영상 소견이 비특이적이므로 부신에서 보일 수 있는 여러 종양과의 감별이 어렵다. 저자들은 좌상복부 통증을 주소로 촬영한 CT 상 좌측 부신 종괴가 발견되고, 2년 동안 1 cm 이상 크기가 증가하여 부신절제술을 받은 후 병리조직검사에서 평활근육종으로 진단된 증례를 영상 소견을 중심으로 보고하고자 한다.

Esophageal leiomyosarcoma is a rare lesion. [0.5 % of all esophageal malignancy] The patient was 74 year old female and complained postprandial vomiting of 4 years, duration & hematemasis of 2 months` duration. On gastrofiberscopy, huge exophytic mass nearly occluding esophageal lumen located 30∼38 cm from upper incisor was found. Endoscopic biopsy was squamous cell carcinoma. Transthoracic esophagectomy and esophagogastrotomy was carried out. Result of biopsy was esophageal leiomyosarcoma.

Leiomyosarcoma of the oral cavity is a very rare tumor that is associated with aggressive clinical behavior and low survival. In this paper, we report a case of leiomyosarcoma presenting with a gingival exophytic mass that rapidly grew, causing facial asymmetry within 16 days, in a 9-year-old boy. After an excisional biopsy, microscopy revealed a spindle cell neoplasm that, on immunohistochemistry analysis, demonstrated reactivity for SMA. This established the diagnosis of leiomyosarcoma; subsequently, a marginal mandibulectomy and supraomohyoid neck dissection were performed.

Leiomyosarcoma may occur anywhere in the body but rarely occurs in the heart or great vessels. Leiomyosarcoma may be managed by surgical resection with or without chemotherapy or radiotherapy. Owing to the high rate of metastasis and poor prognosis, a definitive treatment modality for leiomyosarcoma has not yet been suggested. This case study reports the surgical management of the recurrent leiomyosarcoma of the heart and the great vessels in a 63-year-old woman.

원발성 폐평활근육종은 매우 드문 종양으로 임상 소견 및 방사선 소견이 기관지 상피암과 유사하다. 저자들은 기침을 주소로 내원하여 원발성 폐평활근육종으로 진단된 1예를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.

원발성 기관지 평활근육종은 매우 드문 종양으로서, 종양 조직의 객담 배출에 의해 진단된 보고는 아직 없다. 저자들은 종양 조직의 객담 배출에 의해 진단된 원발성 기관지 평활근육종 환자를 보고하고자 한다. 객담으로 배출된 종양 조직은 병리학적으로 평활근육종으로 진단되었으며, 우측 하엽 절제술과 임파절 절제술을 시행하였다. 절제된 종양의 병리조직 소견은 이전에 객담으로 배출된 종양의 조직 소견과 동일하였고 기관지내에 국한되어 있으면서 주위 폐 조직이나 임파절은 침범하지 않았다.

Leiomyosarcoma of the larynx is very rare, and rarely been described in reference to the head and neck region. This tumor occurs mainly in the uterus, the gastrointestinal track, and the retroperitoneum. There have been 24 previously reported cases of this tumor involving the larynx in the literature. Histologic diagnosis remains extremely difficult. A case of leiomyosarcoma of the larynx, treated by total laryngectomy, is reported. We discuss the clinical presentation, diagnosis, and treatment of leiomyosarcoma with a review of the literature.

Leiomyosarcoma is extremely rare in the oral cavity and especially in the mandible. At first. the case of this report was diagnosed as odontogenic fibroma but after approximately 3.5 years. it was diagnosed as leiomyosarcoma. Conventional radiograph of the first time showed an ill-defined radiolucent lesion in the mandible. After local recurrence. CT images showed a large irregular soft tissue mass with some necrotic areas. These findings were not specific for leiomyosarcoma, but they suggested that this lesion was a recurrent soft tissue sarcoma. Histopathological examinations using H & E staining, immunohistochemical staining and Masson's trichrome staining confirmed this case as leiomyosarcoma. Deciding its malignancy or benignancy, defining the tumor extent and its relationship to the surrounding anatomic structures, and evaluating the distant metastasis are more important roles of radiographic examination than finding out the name of disease.
