고환 림프종은 무통성 종괴를 주소로 내원하는 드문 고환 종양이다. 일반적으로 고환 림프종은 칼라 도플러 초음파에서 고혈관성을 보이며, 컴퓨터단층촬영이나 자기공명영상에서 조영증강을 보인다. 저자들은 우측 고환 종대를 주소로 내원한 67세 환자에서 초음파 검사상 크기가 커진 고환 내 혈류가 보이지 않아 계류염전으로 진단하였으나, 전산화단층촬영에서는 주변부에 일부 조영증강을 보이는 종괴로 관찰되었고, 수술 이후 림프종이 진단된 증례를 경험하여 보고하고자 한다.

Onco-testicular sperm extraction is used to preserve fertility in patients with bilateral testicular tumors and azoospermia. We report the case of a testicular tumor in the solitary testis of a patient who had previously undergone successful contralateral orchiectomy and whose sperm was preserved by onco-testicular sperm extraction. A 35-year-old patient presented with swelling of his right scrotum that had lasted for 1 month. His medical history included a contralateral orchiectomy during childhood. Ultrasonography revealed a mosaic echoic area in his scrotum, suggesting a testicular tumor. The lesion was palpated within the normal testicular tissue along its edge and semen analysis showed azoospermia. Radical inguinal orchiectomy and onco-testicular sperm extraction were performed simultaneously. Motile spermatozoa were extracted from normal seminiferous tubules under microscopy and were frozen. Eventual intracytoplasmic sperm injection using the frozen spermatozoa is planned. Onco-testicular sperm extraction is an important fertility preservation method in patients with bilateral testicular tumors or a history of a previous contralateral orchiectomy.

심장 전이는 환자가 사망하기 전에 진단되는 경우가 드물다. 저자들은 고환 융모암의 다발성전이를 보였던 26세 남자에서 심장 전이를 진단하였고 심장초음파에서 심실중격에서 기원하여 우심실유출로에 유동하는 종괴를 확인할 수 있었다. 우심실로부터 제거한 종괴의 조직학적 소견은 고환 융모암에 합당한 소견을 보였고 환자는 수술적 치료 및 항암화학요법 후에 안정된 회복을 보였다. 국내에는 고환 융모암의 심장 전이를 수술적으로 제거함으로써 성공적인 치료 효과를 보였던 증례 보고가 없어 보고하고자 한다.

선천 부신 과다형성 환자에서 고환 부신 잔류 종양은 흔하게 발생한다. 대개 이 종양은 적절한 corticosteroid 억제 치료로 호전될 수 있다. 저자들은 양측성 고환 부신 잔류 종양을 보인 21-hydroxylase 결핍증 환아에게서 corticosteroid를 투여하였으나 반응하지 않아 고환 적출술을 시행한 사례를 경험하였기에 보고하는 바이다.

Background: Testicular cancer management is considered a marvel of modern science with excellent treatment results. Pakistan has a distinct ethnic variation and geographic distribution but data regarding clinical presentation of testicular tumors and their management is under reported. The objective of this study was to determine clinical profile, treatment modalities and survival outcome of testicular tumors in the Pakistani population. Materials and Methods: A retrospective review of patients who received treatment for testicular cancer at Shaukat Khanum Cancer Hospital from January 2009 to December 2012 was performed. Patient demographics, clinical features at presentation and treatment modalities were assessed. For categorical variables chi square test was used. Survival was calculated using Kaplan Meier survival curves and Log rank test was employed to determine significance. Results: The most common tumor was mixed germ cell tumor in 49% patients. For all tumor variants except seminoma, stage III was the most common clinical stage at presentation. Majority of patients with non seminomatous germ cell tumors presented in the15-30 year age group as compared to seminoma which was most prevalent in the 30-40 year age group. Orchiectomy followed by chemotherapy was the most common treatment modality in 80% patients. Expected 5 year survival for seminomas and non-seminomatous germ cell tumors was 96% and 90% respectively which was not significantly different (p=0.2). Conclusions: Despite a distinct clinical profile of testicular tumors in Pakistani population, survival is comparable with published reports.

Granular cell tumor was described in the testis of two rabbits. Testis from each rabbit was surgically removed and submitted for histopathological diagnosis. Both testes were about 2.0 cm in diameter, firm, and tan. Microscopically, testicular mass consisted of compact sheets of round to polygonal and occasional spindle-shaped cells. The neoplastic cells contain a large amount of eosinophilic granular material in the cytoplasm. The cytoplasmic eosinophilic granules were positive for periodic acid Schiff stain. Immunohistochemically, the neoplastic cells were immunoreactive to Melan-A and vimentin. Based on these results, the testicular mass was diagnosed as a granular cell tumor.

음낭 종양은 고환, 부고환, 정삭, 고환막 등에서 발생하며 악성 가능성을 평가하는데 가장 중요한 요소는 병변의 위치이다. 추가적인 영상 소견과 임상 정보를 종합하여 효과적으로 진단할 수 있다. 초음파검사는 표재성 기관인 음낭을 관찰하기 용이하며, 우수한 영상 품질을 바탕으로 병변의 유무뿐만 아니라 위치와 성상까지 확인 가능하다. 초음파검사로 감별이 어려울 경우에는 자기공명영상을 이용하여 지방, 출혈, 섬유화, 조영증강 등 추가적인 종양의 특징을 확인하는 것이 진단에 도움이 된다. 전산화단층촬영은 고환암의 병기결정이나 복강 내 미하강고환의 위치를 탐색하는데 유용하다. 본 종설에서는 고환 내외에서 발생하는 음낭 종양의 영상 소견을 살펴보고자 한다.

Precocious puberty is difficult to define because of the marked variation in the age at which puberty begins normally, onset of puberty before 8 years of age in girls and 9 years in boys may be considered precocious. The etiology of precocious puberty in boys is usually idiopathic, but can result from adrenal and testicular tumors. The hepatoblastoma that produces hCG is a very rare functioning tumor known to cause precocious puberty in boys. Recently, author experienced one case of virilizing adrenal cortical adenoma in 22 month-old boy, one case of adrenal cortical carcinoma in 28 month-old boy, and one case of virilizing hCG-producing hepatoblastoma in 7 year-old boy and reviewed literatures.

Treatment outcomes of pediatric cancers have improved greatly with the development of improved treatment protocols, new drugs, and better supportive measures, resulting in overall survival rates greater than 70%. Survival rates are highest in acute lymphoblastic leukemia, reaching more than 90%, owing to risk-based treatment through multicenter clinical trials and protocols developed to prevent central nervous system relapse and testicular relapse in boys. New drugs including clofarabine and nelarabine are currently being evaluated in clinical trials, and other targeted agents are continuously being developed. Chimeric antigen receptor-modified T cells are now attracting interest for the treatment of recurrent or refractory disease. Stem cell transplantation is still the most effective treatment for pediatric acute myeloid leukemia (AML). However, in order to reduce treatment-related death after stem cell transplantation, there is need for improved treatments. New drugs and targeted agents are also needed for improved outcome of AML. Surgery and radiation therapy have been the mainstay for brain tumor treatment. However, chemotherapy is becoming more important for patients who are not eligible for radiotherapy owing to age. Stem cell transplant as a means of high dose chemotherapy and stem cell rescue is a new treatment modality and is often repeated for improved survival. Drugs such as temozolomide are new chemotherapeutic options. In order to achieve 100% cure in children with pediatric cancer, every possible treatment modality and effort should be considered.

Mammary gland tumors are very rare in male dogs. In this study, four mammary gland tumors from 3 male dogs (2 intact, 1 neutered) were collected from local animal hospitals. The dogs included two purebred Shih Tzu (1 intact, 1 neutered) and one intact purebred Cocker Spaniel. The mean age of dogs with mammary gland tumors was 9 years (5-12 years). Two dogs had a solitary mass, whereas one dog had two mammary masses. Of the four tumor masses, three were observed in the fourth or fifth mammary glands, and one was observed in the third mammary gland. According to histopathologic examinations, all four mammary masses from three dogs were benign tumors including two benign mixed tumors in one case and two complex adenomas. There were no history of obesity, testicular tumors, diabetes, and sex hormonal therapy in any male dogs with mammary tumors. Surgical excision was the only reported treatment for these tumors. No recurrence or metastasis was recorded up to 25 months after surgery.
