In this report, a case of a 70-year-old man with a large ganglion cyst formed after anterior transposition of the left ulnar nerve is presented. Three months after the index surgery, the patient presented with a painless superficial ovoid, soft mass measuring $5{\times}4{\times}2cm$ in size located at the posteromedial aspect of the left elbow, the previously operated site. Magnetic resonance imaging showed a well demarcated cystic mass with a stalk connecting to the elbow joint. Excisional biopsy was performed and pathologic findings showed that the cystic wall had no definite lining cells with myxoid degeneration compatible with findings of ganglion cyst.

A case of spindle cell tumor was presented in a 16-month-old, female syrian hamster. In the left chest area, a 3cm firm elevated recurrent mass was found, surgically removed, and submitted to the Department of Veterinary Pathology, Seoul National University for diagnosis. The mass was soft to firm and tan on sectioning, and contained hemorrhagic area. Histologically, the tumor was composed of sheets of interlacing bundles of spindle-shaped cells with moderate amount of cytoplasm and oval to fusiform nuclei. They were plemorphic and contained 1 to 3 prominent nucleoli. Based on the gross and histological findings, the tumor was diagnosed as a subcutaneous spindle cell tumor. However, the exact origin of neoplastic cells remained undetermined.

A gingival mass was detected from a 1-year-old female Great Dane dog. After surgical removal, the lesions recurred in 2 weeks and died of septicemia. Characteristic histologic features were large numbers of multinucleated giant cells which were connected with capillary vessels. Neovascularization was prominent with mononuclear and polynuclear cell infiltration. Overall features of these lesions except for giant cell infiltration were similar to granuloma. From these results, a gingival mass excised from a dog was diagnosed to be a peripheral giant cell granuloma (PGCG). This is the first report of canine subcutaneous PGCG in Korea.

서울에 거주하는 32세 가정주부가 좌하측 흉벽에 발생한 직경 약 3cm인 종괴를 제거하기 위하여 입원하였다. 종괴는 지난 3개월간 네번 켜졌다가 없어지고는 하였다. 수술 소견상 전거상근(전거상근)내에 육아종이 있었고 그 안에서 미성숙 간질 충체를 발견하였다. 이 증례를 우리나라의 인체 간질 감염 제11례로 보고한다. 간질의 이소기생중 가장 흔한 것으로 알려진 피하기생례로는 우리나라에서는 처음으로 경칩한 중례이며 앞으로 기생충성 피하종괴의 감별대상에 간질(간질) 감염도 고려하여야 한다고 생각한다.

Tumor incidence in wild mammals is reportedly very low. Wild nutria, a large rodent, is known to carry many infectious diseases, but rarely exhibits neoplastic diseases. We necropsied a male wild nutria and found a large nodular mass in the left inguinal region, adjacent to the penis. Histopathologically, the mass was diagnosed as preputial gland adenoma. Spontaneous preputial gland adenomas are extremely rare in all animals. Moreover, reports of tumors in nutrias have been limited to adenocarcinomas of the lungs and uterus, as well as subcutaneous fibromas. Here, we describe preputial gland adenoma in a wild nutria.

Purpose: Pseudohypoparathyroidism is a hereditary disorder characterized by symptoms and signs of hypoparathyroidism, typically in association with distinctive skeletal and developmental defects. Hypoparathyroidism is caused by a insufficient end-organ response to PTH (parathyroid hormone). Hypoparathyroidism consists of four types in which the most common form, pseudohypoparathyroidism-Ia, accompany with Albright's hereditary osteodystrophy. We experienced a case of a woman who had been suffering from calcified mass on left foot, diagnosed Albright's hereditary osteodystrophy. Methods: We present a case of a 24-year-old Korean female who visited plastic surgery department with a painful mass on dorsum of the left foot. On the physical exam, bony hard and painful mass, fixed to dermis, was noted. Plain X-ray films demonstrate suspicious calcification on subcutaneous tissue of dorsum of the left foot. The patient was diagnosed pseudohypoparathyroidism 2 years ago at the plastic surgery department. At the visiting time, the laboratory results were within normal range even though the patient actually had a disease. The reason is because the patient has been treated with Vit.D, calcium replacement therapy and thyroid hormone therapy. Moreover, the patient has been treated with anticonvulsant agents due to epilepsy. On the brain computer tomography (CT), calcification was noted on the basal ganglia and dentate nucleus. So we decided the total excision of entire mass from the left foot. Results: We excised main mass with numerous pinhead sized masses which were scattered around the main mass. The $6.0{\times}4.0{\times}0.5\;cm$ sized main mass was bony hard, and its surface was flat and margin was irregular. The permanent biopsy was confirmed that the main mass and all the scattered tiny masses were heterotopic calcification. The patient did not suffer from the pain after the mass excision. The wound has been healed without any problem. Conclusions: Heterotrophic calcification is often accompanied with pseudohypoparathyroidism, but such a huge one is uncommon. We report a case of pseudohypoparathyroidism with heterotrophic calcification developed in dorsum of left foot who was diagnosed by excisional biopsy.

목적 지선낭종의 초음파 소견을 분석하고, 표피낭종 및 지방종과의 감별진단에 도움이 되는 소견을 알아보고자 하였다. 대상과 방법 10명의 환자에서 14개의 조직학적으로 확진된 지선낭종의 초음파 소견을 후향적으로 검토하였다. 병변의 위치, 모양, 경계, 에코 발생 정도, 후방 음향 특징 및 테두리 벽 또는 병변 내 줄무늬의 존재 여부를 평가하였다. 지선낭종의 초음파 소견을 분석하고, 표피낭종 및 지방종과의 감별진단에 도움이 되는 소견을 알아보고자 하였다. 결과 지선낭종의 대부분은 피하 종괴(n = 6, 42.9%) 또는 피부층과 피하층을 함께 침범한 종괴로(n = 6, 42.9%) 나타났다. 병변은 대부분 경계가 잘 지어지고(n = 12, 85.7%) 균질한 에코 발생을 보였으며(n = 9, 64.3%), 후방 음향 특징을 나타내지 않았다(n = 9, 64.3%). 표피낭종을 지선낭종과 구별하는 가장 중요한 소견은 균질한 내부 에코 발생과(p = 0.009), 현저하지 않은 후방 음향 향상이다(p < 0.001). 지선낭종과 지방종의 구별되는 특징은 경계(p < 0.001), 에코 발생성(p = 0.034), 내부 에코 성상(p = 0.004) 및 병변 내 줄무늬의 부재였다(p < 0.001). 결론 지선낭종은 초음파 검사상 경계가 좋고 균질하며, 후방 음향 향상이 경도로 있거나 없는 종괴로 관찰되었다.

Purpose: Malignant peripheral nerve sheath tumors most often arise from the anatomically discernible peripheral nerve or neurofibroma. Methods: A 55-year-old man had a rapidly growing pedunculated large mass on the sacrolumbar junction for 2 years. He has congenital neurofibromatosis type I. He had multiple caf-au-lait spots and multiple neurofibromas on the entire body. The mass developed from a subcutaneous nodule on the sacrolumbar junction and grew rapidly. The preoperative punch biopsy revealed a malignant peripheral nerve tumor. The mass was completely excised with 1 cm free margin above the deep fascial plane. Results: There was no evidence of recurrence of tumor for 19 months of follow-up examination. Conclusion: Malignant peripheral nerve sheath tumor is very rare and has unique feature. We report a successful case of malignant peripheral nerve sheath tumor with the review of the literatures.

A 10-year-old female patient presented with a rapidly growing nodular mass lesion on her right frontal area. On skull radiography and computed tomography (CT) imaging, this mass had a well-demarcated punch-out lesion with a transdiploic, exophytic soft tissue mass nodule on the frontal scalp. Magnetic resonance (MR) imaging revealed the presence of a $1.5{\times}1.2{\times}1$ cm sized calvarial lesion. This lesion was hypointense on T1 and heterogenous hyperintense on T2 weighted MR images, and exhibited heterogeneous enhancement of the soft tissue filling the punch-out lesion after intravenous administration of gadolinium. En block removal of the tumor with resection of the rim of the normal bone was performed. The pathological diagnosis was intravascular papillary endothelial hyperplasia (IPEH). After surgery, no recurrence was found for 8 months. IPEH is a rare and benign reactive lesion usually found in thrombosed subcutaneous blood vessels. Involvement of skull bone is rare. In this article, we present a case of IPEH involving the calvarium, in a 10-year-old woman.
