Abstract
Testicular tumors in the prepubertal age are relatively rare, representing only 9.4% of the total testicular and paratesticular specimens from a 20-year review performed at a large pediatric hospital [ 1 ]. They account for 1% to 2% of all solid tumors in the pediatric age group, with an annual incidence between 0.5/100 000 and 2/100 000 boys according to Coppes et al [ 2 ] and data from the Prepubertal Testicular Tumor Registry [ 3 ]. Similar to other neoplasms afflicting children, a bimodal age distribution is observed. The first peak is between birth and 3 years of age, and a second one occurs at the onset of puberty, extending to the fourth decade. Reports on their frequency vary because some investigators include the adolescent period, while others do not [ 4 ]. The vast majority of testicular tumors are germ cell neoplasms, accounting for 95% across all ages [ 5 ]. In children, germ cell tumors also predominate, representing 71% of all testicular neoplasms. These include yolk sac tumors (49%), teratomas (13%), seminomas and mixed germ cell tumors (9%), and sex-cord stromal tumors (29%). Malignant potential is significantly lower (less than 70%) in the pediatric age group compared to adults (90%) [ 6 ]. According to Pohl et al, 74% of prepubertal testicular tumors are benign [ 7 ].

Epithelioid hemangioma of the spine: a case series of six patients and review of the literature. Spine J 2013; 13:e7-13. [PMID: 24045160 DOI: 10.1016/j.spinee.2013.06.070] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/21/2012] [Revised: 04/15/2013] [Accepted: 06/24/2013] [Indexed: 02/03/2023]
Abstract
BACKGROUND CONTEXT Epithelioid hemangioma (EH) of bone is a benign vascular tumor that can be locally aggressive. It rarely arises in the spine, and the optimum management of EH of the vertebrae is not well delineated. PURPOSE The report describes our experience treating six patients with EH of the spine in an effort to document the treatment of the rare spinal presentation. STUDY DESIGN This study is designed as a retrospective cohort study. PATIENT SAMPLE A continuous series of patients with the diagnosis of EH of the spine who presented at our institution. OUTCOME MEASURES The clinical and radiographic follow-up of the patient population is documented. METHODS The Bone Sarcoma Registry at our institution was used to obtain a list of all patients diagnosed with EH of the spine. Medical records, radiographs, and pathology reports were retrospectively reviewed in all cases. Only biopsy-proven cases were included. RESULTS The six patients included five men and one woman who ranged in age from 20 to 58 years (with an average age of 40 years). The follow-up available for all six patients ranged from 6 to 115 (average 46.8) months. All patients presented with lytic vertebral body lesions. Five patients presented with pain secondary to their tumor, and the tumor in the sixth patient was found incidentally during the workup for a herniated disc. Three patients required surgical management for instability secondary to the destructive nature of their tumors, and two other patients required emergent decompression secondary to spinal cord compression by the tumor. The sixth patient was treated expectantly after biopsy confirmation. Three patients received postoperative radiation therapy as gross tumor remained after surgery. Three patients had gross total resections and did not receive postoperative radiation. Preoperative embolization was used in four patients. One patient continued to have back pain after surgery and radiation and another continued to have ataxia after surgery and radiation. No tumor locally recurred or progressed. CONCLUSIONS Our data suggest that EH of the spine can be locally aggressive and lead to instability and cord compression. Surgery is required in such instances; however, observation should be considered in patients without instability or cord compression.

Abstract
Testicular hemangioma is a very rare neoplasm with only 25 cases reported in the English literature. We describe 8 cases of testicular hemangioma encountered at our institution between 1992 and 2012. Of the 7 consult cases, 4 were malignant, 1 a Leydig cell tumor, and 2 were recognized as hemangiomas. The patients' ages ranged from 9 to 54 years (mean 32; median 30). Seven patients presented with self-detected palpable masses, and 2 patients reported pain. Six hemangiomas involved the right testis, and 2 were left sided. Ultrasonography recognized hypervascularity in 3 cases. History of pelvic irradiation, chemotherapy, and remote scrotal trauma was present in 3 patients. Preoperative serum tumor markers were negative (2/2 cases). The average size was 1.7 cm (median 1.8; range, 0.5 to 3.0). Six cases were infiltrative within the testis and entrapped benign seminiferous tubules, and 3 tumors invaded the tunica albuginea. Three hemangiomas were epithelioid, 2 anastomosing, 1 cellular capillary, 1 capillary, and 1 cavernous. Mitoses were sparse in all but 1 case, which reached up to 5 per 10 HPF. In 6 cases, seminiferous tubules adjacent to the hemangioma were atrophic without spermatogenesis. Immunohistochemical analysis was performed in 6 cases, and tumors stained with CD31, CD34, FVIII-related protein, and FLI-1 but not with pancytokeratin AE1/3, epithelial membrane antigen, keratin 8/18, placental alkaline phosphatase, human herpes virus 8, human chorionic gonadotropin, c-kit, melan-A, or p53. In cases with follow-up, there were no recurrences in 7 patients (mean 21 mo; median 12 mo; range, 1 to 72 mo). In summary, testicular hemangioma is a rare neoplasm with different morphologies having in common an infiltrative growth pattern with entrapment of seminiferous tubules, which should not be considered a feature of malignancy. Clinical and radiologic findings may preoperatively suggest a vascular tumor.

Abstract
Kaposiform haemangioendothelioma is a very rare vascular tumour of intermediate (borderline) malignancy, typically occurring in the skin and soft tissues of the extremities in infants and children. We report two morphologically and immunophenotypically classical cases occurring in the testicular parenchyma of old adults, review the literature on vascular tumours of the testis and discuss the differential diagnosis of these unusual cases.

Abstract
Adenomatoid tumors (ATs) are uncommon benign mesothelial tumors with a predilection for the genital tract. We reviewed 47 ATs diagnosed at our institutions during 10-year period. Thirty tumors (64%) originated in the female (21 uterine, 8 tubal, and 1 ovarian) and 17 (36%) in the male (9 epididymal and 8 testicular) genital tract. The median age for females and males was 47.5 and 51 years, respectively. While 83% of tumors in females were incidental findings in resections for unrelated diseases, 94% of male lesions presented as clinical masses leading to surgery. The median size was 2, 1, and 0.5 cm for uterine, epididymo-testicular, and tubo-ovarian lesions, respectively. Architecturally, the microcystic/angiomatoid pattern was the most frequent (32/47; 68%), followed by combined microcystic/trabecular (26/47; 55%) and retiform/adenoid (15/47; 32%) pattern. The trabecular/solid (6%) and macrocystic (4%) patterns were uncommon. However, 57% of cases revealed ≥2 growth patterns. Taken by anatomic site, 20 of 21 uterine cases were at least focally microcystic but none was retiform. In contrast, the retiform pattern dominated in male genital tract tumors (12/17; 71%). Immunohistochemistry showed expression of calretinin (36/36) and D2-40 (30/30) and lack of CD34 (0/30) and PAX8 (0/32). GLUT-1 was expressed in 11/11 male genital tract tumors but in none of the microcystic uterine lesions. Estrogen and progesterone receptor expression was weak and focal (two and three uterine cases, respectively). None stained for the androgen receptor. Our study illustrates the great site-specific morphological diversity of ATs emphasizing their wide site-dependent differential diagnosis.

Abstract
BACKGROUND We describe 6 cases of a poorly recognized vascular neoplasm that can simulate angiosarcoma. DESIGN Cases of a rare vascular tumor with a proclivity for the genitourinary tract encountered in our consultation material were prospectively collected between the year 1999 and 2008. Follow-up information was obtained when possible. RESULTS There were 6 tumors from 4 men (66%) and 2 women, ranging in age from 49 to 75 years (median, 59.5) involving the kidney and renal hilum (4, 66%) and testis (2). Tumors ranged from 1.3 to 1.7 cm (median, 1.6 cm) and were grossly well-marginated with a hemorrhagic mahogany spongy appearance. Microscopically, at low power they had a loosely lobulated architecture and were associated with a medium-caliber vessel (5/6, 83%). Most kidney (3/4, 75%) tumors showed minor extensions into adjacent adipose tissue. At higher magnification, the tumors consisted of anastomosing sinusoidal capillary-sized vessels with scattered hobnail endothelial cells within a framework of nonendothelial supporting cells. There was a minimal inflammatory backdrop consisting of lymphocytes but not plasma cells or acute inflammation. Mitoses were absent (5/6, 83%) or rare (1 case; in supporting cells). There was mild cytologic atypia in one of the cases but no multilayering of endothelial cells in any case. Vascular thrombi were typical (5/6, 83%) and the lesions had zones of central sclerosis with focal necrosis (5/6, 83%). Two (33%) tumors featured prominent extra-medullary hematopoiesis and 2 tumors (33%) had striking hyaline globules reminiscent of those seen in Kaposi's sarcoma. Immunohistochemistry was available on some cases and the lesions stained with CD34, CD31, and FVIII but not human herpes virus type 8, keratin AE1/3, epithelial membrane antigen, HMB45, placental alkaline phosphatase, or human chorionic gonadotropin. In all but one submitted consultation, the possibility of angiosarcoma had been raised based on the anastomosing vascular pattern. On follow-up, there were no recurrences or metastases in 5 cases (range: 8 to 36 mo; median 12 mo, mean 15 mo), and 1 patient was lost to follow-up. CONCLUSIONS Anastomosing hemangioma of the genitourinary tract is a rare neoplasm displaying some overlapping features of both sinusoidal hemangioma and hobnail hemangioma of soft tissue and skin. However, in our opinion, it is a unique neoplasm with a proclivity for the kidney. Its anastomosing appearance can lead to concern for angiosarcoma but, despite small numbers and limited follow-up in our series, evidence to date supports that the lesion is benign.

Abstract
Adenomatoid tumors of the female and male genital tracts are well characterized as mesothelial in origin, but a detailed histological and immunohistochemical analysis comparing both traditional and newer mesothelial markers across gender and site has not been formally conducted. A variety of morphologic features previously described as characteristic of adenomatoid tumors were evaluated in 44 adenomatoid tumors from the male and female genital tracts. Immunohistochemical analysis with pankeratin (AE1/CAM5.2), WT-1, calretinin, CK5/6, D2-40, and caldesmon was also performed. The extent and intensity of staining were scored semiquantitatively on one representative section per case and mean value for each parameter was calculated. All (n=44) the adenomatoid tumors from both the female and male genital tracts demonstrated a distinctive thread-like bridging strand pattern. Lymphoid aggregates were seen in all 12 adenomatoid tumors of male patients, but in only 4 of 32 (13%) tumors in female patients (P<0.0001). The remaining morphologic features were variably present with no clear sex predilection. Pankeratin, calretinin, and D2-40 reactivity were identified in all female (n=32) and male (n=12) genital tract adenomatoid tumors. Adenomatoid tumors expressed WT-1 in 11/12 (92%) male patients and in 31/32 (97%) female patients. In male patients, reactivity for CK5/6 and caldesmon was found in 1/12 (8%) and 0/12 (0%) adenomatoid tumors (respectively), whereas reactivity in female patients was found in 5/32 (16%) and 1/32 (3%); respectively. Female tumors differ from their male counterparts by the frequent absence of lymphoid aggregates and the presence of a circumscribed margin when occurring in the fallopian tube. Of the putative mesothelial markers evaluated, calretinin, D2-40, and WT-1 show a similar immunoprofile and have a higher sensitivity than CK5/6 and caldesmon in genital tract adenomatoid tumors. However, the presence of additional, often strong expression of WT-1 in normal tissues of the female genital tract limits the utility of WT-1 in this setting.

Abstract
The clinical and pathologic features of 50 epithelioid hemangiomas of bone are analyzed. There were 29 males and 21 females who ranged in age from 10 to 75 (mean 35) years. The tumors arose in long tubular bones (40%), short tubular bones of the distal lower extremity (18%), flat bones (18%), vertebrae (16%), and small bones of the hands (8%). Nine patients (18%) had involvement of more than 1 bone. Radiographically, the lesions were lucent and well marginated. Microscopically, the neoplasms had a lobular architecture and were composed of epithelioid endothelial cells that formed obvious vascular lumina or grew in solid sheets. No hyalinized or solid appearing extracellular myxoid matrix was present. Thirty-five patients were treated with curettage, 13 patients had a local resection and 2 patients only had a biopsy. One patient had local lymph node involvement. Three patients were treated with surgery and radiation therapy. Follow-up information revealed that 4 patients experienced a local recurrence; and 1 patient developed limited involvement of a regional lymph node. Epithelioid hemangioma of bone is a benign lesion that may be multifocal and affect separate tissue and is successfully treated with curettage or marginal en bloc excision.

Abstract
INTRODUCTION Though theoretically in the paratesticular region one can develop any type of benign tumour of soft tissues, they are the lipomas, leiomyomas and adenomatoid tumours the most usual whereas the hemangiomas are less common. We contribute a new case of epididymis intrascrotal hemangioma (HI), valuing the bibliography that allows us to know the incidence and clinic-pathologic characteristics of these tumours. MATERIAL AND METHOD A 74-year-old patient includes for study with right scrotal tumour, who is practised orchiectomy. Hystopathologic study is realized. Of equal form there is realized a bibliographical examination of this type of tumours across Medline and of not index-linked search with conceptual review and of the literature. RESULTS The injury corresponds with a HI cavernous trombosed of epididymis with testicular parenchyma respected. Your hystopathologic diagnosis does not present problems, whereas the clinical one and ultrasonographic study, reaches the whole spectrum of tumours, benign and malignant of soft tissues. The number of intrascrotal hemangiomas of epididymis described in the literature is very limited. CONCLUSIONS The scrotal tumours are necessary a preoperatory clinical and sonographic study completely, in spite of the fact that they are diagnosed the majority after your surgical removal. The complex system of the tissues on the zone paratesticular implies that the differential enclosed diagnosis does not allow to differentiate, malignant tumours of benign. The low incident of many of these masses has determined the mistake of standardized protocols for your diagnosis but also for their unified treatment.

Abstract
We present the clinical course, sonographic and MRI findings of an intratesticular arteriovenous malformation (AVM) found in a patient during routine check-up for infertility evaluation. Seven years ago, patient's refusal for surgical removal of the lesion led to follow-up ultrasound examinations and finally to an MRI examination. Arteriovenous malformations of male genitalia have been reported in the literature (penis, scrotum, spermatic cord and epididimys). However, this is the second case of an intratesticular AVM and the first one with a long clinical follow-up.

Abstract
A case of testicular capillary haemangioma is reported and the importance of intraoperative examination of this very rare lesion emphasised. Capillary haemangioma of the testis can be similar to malignant testicular tumours on clinical presentation, as well as on ultrasonography and magnetic resonance imaging, and therefore should be included in the intraoperative differential diagnosis. Because of the benign nature of this lesion, conservative surgical treatment by means of tumour enucleation with preservation of the testis is possible, if intraoperative examination of frozen sections of representative tissue can be performed.

Abstract
We report two cases of small pleural nodules showing the distinctive histologic appearance of adenomatoid tumor. Both lesions were discovered incidentally during surgery in patients undergoing lung resection for unrelated intrapulmonary masses: lung carcinoma in one case and histoplasmosis in the other. The tumors were composed of a focal proliferation of epithelioid cells forming vacuoles and tubular spaces in a fibrous stroma, as seen in adenomatoid tumors from other sites. The differential diagnosis in both cases included metastatic signet ring cell carcinoma. The mesothelial nature of the lesions was supported by immunohistochemical and ultrastructural evidence. The tumor cells in both cases were positive for cytokeratin but negative for carcinoembryonic antigen and LeuM1. One case was also negative for BER-EP4, B72.3, CD34, and Factor VIII. Electron microscopy in this case demonstrated well-developed basal laminae, desmosomes, and numerous slender microvilli along the luminal surfaces of the tumor cells. Adenomatoid tumors are regarded as a benign variant of mesothelioma. Despite the abundance of mesothelial cells in the pleura, adenomatoid tumors are apparently extremely rare in this location. Separation from malignant lesions such as adenocarcinoma and epithelioid hemangioendothelioma is important.

Abstract
Testicular and paratesticular neoplasms are uncommon tumors of childhood. Consequently, the experience gained with regard to their optimal management is limited in any given children's cancer centre. Here we review the classification, diagnosis, and staging of testicular and paratesticular neoplasms and subsequently discuss the more frequently occurring ones: germ cell tumors, gonadal stromal tumors, gonadoblastoma, tumors of the supporting tissue, lymphomas and leukemias, tumor-like lesions, secondary tumors, and tumors of the adnexa.
