Prognostic Factors for Pediatric Testicular Torsion Outcomes

@#Introduction: Testicular torsion is a urological emergency causing spermatic cord twisting. Delayed management can cause poor outcome, i.e. orchiectomy. Here, we investigated several prognostic factors, including age, onset, clinical symptoms, leukocyte count, for testicular torsion outcomes (orchiectomy vs. orchiopexy) in children in Indonesia. Methods: A retrospective review of 23 patients with testicular torsion who underwent scrotal exploration from July 2013 to November 2018 at our institution was done. Results: The age at testicular torsion diagnosis was 12.8 (interquartile range, 4.6-15.1) years. Only fever showed strong significant prognostic factor for orchiectomy (OR=20; 95% CI=1.6 – 248; p=0.017), while other factors were not, with p-value of 0.54, 1.0, 1.0, 0.19, 1.0, 0.62, 0.62, 0.58, and 0.62, for age, onset, scrotal pain, abdominal pain, hyperemia, edema, nausea, vomitus and white blood cells count, respectively. Furthermore, logistic regression test also revealed that fever is a strong prognostic factor for orchiectomy (OR=22.6; 95% Cl=1.3 – 394.2; p=0.033). Conclusion: The patient with testicular torsion with fever tends to undergo orchiectomy. Further multicenter studies with a larger sample size are necessary to confirm our findings.

Lymphoma Of Testis-A Rare Case Report

Primary testicular lymphoma constitutes 1-2% of Non-Hodgkin's lymphomas affecting elderly men >60 years of age. The most common histologic type is Diffuse large B cell lymphoma (DLBCL). Differential diagnosis includesseminoma, embryonal cell carcinoma, granulomatous orchitis, pseudolymphoma and plasmacytoma.Treatment involves multimodality approach involving surgery, chemotherapy and radiotherapy. Despite aggressive therapy, prognosis of this neoplasm is poor.

Histomorphological changes in the common carotid artery of the male rat in induced hypogonadism / 대한해부학회지

The role of androgens in the development of cardiovascular diseases remains controversial. The current study therefore sought to determine the changes in the histomorphology of the common carotid artery of the male rat in orchidectomy-induced hypogonadism. Twenty-two Rattus norvegicus male rats aged 2 months were used. The rats were randomly assigned into baseline (n=4), experimental (n=9), and control (n=9) groups. Hypogonadism was surgically induced in the experimental group by bilateral orchiectomy under local anesthesia. At experiment weeks 3, 6, and 9, three rats from each group (experimental and control) were euthanized, their common carotid artery harvested, and routine processing was done for paraffin embedding, sectioning, and staining. The photomicrographs were taken using a digital photomicroscope for morphometric analysis. Orchidectomy resulted in the development of vascular fibrosis, with a significant increase in collagen fiber density and decrease in smooth muscle and elastic fiber density. Moreover, there was development of intimal hyperplasia, with fragmentation of medial elastic lamellae in the common carotid artery of the castrated rats. Orchidectomy induces adverse changes in structure of the common carotid artery of the male rat. These changes may impair vascular function, therefore constituting a possible structural basis for the higher incidences of cardiovascular diseases observed in hypogonadism.

A study on causes and management of acute scrotal conditions

Acute scrotal conditions form a significant proportion of cases in surgical ward. They contribute to significant morbidity in younger age group and mortality in older age group. In this study we have attempted to study the causes, aetiology, prevalence and management of acute scrotal conditions. The prevalence in descending order was Acute epididymo orchitis, Pyocele, Hematocele, Fournier’s gangrene, Acute filarial scrotum, Testicular torsion, Scrotal abscess, Mumps orchitis, scrotal trauma. Of these Epididymo orchitis, mumps orchitis and Filarial scrotum were treated conservatively with antibiotics, rest and scrotal support. Fournier’s gangrene, Scrotal abscess and scrotal trauma with wound debridement and reconstruction. Pyocele and hematocele by incision and evacuation of pus and blood respectively. Testicular torsion is treated by surgical de rotation and B/L orchidopexy. Orchidectomy was done if warranted in hematocele, pyocele, and testicular torsion.

A clinicopathological study and management of cholelithiasis

Background: Gallstones are one of the commonest medical problems leading to surgical intervention. There is recent rise in the incidence of cases due to westernization of diet. This study intends to know the various modes of presentation, its complications and various treatment modalities with their outcomes. The aim of the study is to study the prevalence of cholelithiasis and to evaluate the advantages and disadvantages of laparoscopic versus open cholecystectomy surgical procedures. Material and methods: This was a prospective study conducted at tertiary care centre for a period of two years. 100 consecutive cases of cholelithiasis were admitted, investigated and operated during this period and results analysed. Results: Cholelithiasis was common in the 4th decade with majority of cases occurring in females. The commonest clinical presentation was pain abdomen. All the cases were diagnosed on ultrasonography abdomen. The diet consumed was mixed diet. Laparoscopic cholecystectomy was done in 72 cases and 28 cases underwent open cholecystectomy. The conversion rate was 4%. The complications were minimal. Mean operating time for open cholecystectomy was 96 minutes and laparoscopic cholecystectomy was 90 minutes. Mean duration of hospital stay was 9 days for open cholecystectomy and 4 days for laparoscopic cholecystectomy. Conclusion: Laparoscopic cholecystectomy is a safe and effective treatment in most of the patients with symptomatic cholelithiasis. In cases of adhesions and inflammation, open cholecystectomy is preferred.

Primary Intratesticular Rhabdomyosarcoma-A Rare Case Report

Rhabdomyosarcoma is one of most frequent soft tissue sarcoma of skeletal muscle origin. It occurs predominantly in Head& Neck, Genitourinary tract and extremities. The majority of cases of rhabdomyosarcoma in the genitourinary tract occurs in the bladder and paratesticular organs Primary intratesticular Rhabdomyosarcoma is very rare, have aggressive growth pattern. A 15 years old male presented with painless right testicular swelling who underwent high inguinal orchidectomy and left testis appeared normal. Complete blood count , Serum alpha- fetoprotein (1ng/ml) and Beta Human chorionic gonadotropin(<2.39) are with in normal limits.X- ray{chest}reveals multiple variable sized nodules in bilateral lungs with right hilar lymphadenopathy.?Metastasis.HR-USG (scrotum) reveals ill-defined lobulated , heterogeneously hypoechoic, soft tissue mass with increased internal vascularity in the right scrotal region with multiple enlarged lymphnodes suggestive of neoplastic etiology. On histopathology diagnosis of rhabdomyosarcoma –Right testis was made., have aggressive growth pattern. The optimal management of paratesticular rhabdomyosarcoma remains unclear because of the rarity of the disease in adults.Radical orchidectomy with negative surgical margins followed by RPLND and chemotherapy is the recommended treatment. For the control of local recurrence and metastasis radiotherapy is recommended.The purpose of this article is to report a case of 15 years old male with primary intratesticular rhabdomyasarcoma which is very rare and our best knowledge few cases have been reported in the literature till now.

Sertoli cell nodule of the testis: An incidental finding

The case of a 21year old man with complaints of pain in the lower abdomen reported in the surgery OPD. USG showed a case of undescended testis. A radical Orchidectomy was performed and the specimen was received in the department of pathology. Grossly the testis was normal .Microscopic examination showed the encapsulated nodule composed of tubules lined by immature Sertoli cells interspersed with tubules and Spermatogonia and an interwoven network of hyalinised basement membrane having foci of calcification. The findings were identical to those of a Sertoli cell nodule-A typically microscopic encapsulated lesion commonly detected in crypt orchid testes. Here we present a case of undescended testis where incidentally we found all the features of sertoli cell nodule

Endometrioid like yolk sac tumor of the testis with small teratomatous foci: A case report and review of the literature.

I have reported a case of endometrioid like yolk sac tumor of the testis in a 20-yearold boy. Endometrioid like yolk sac tumor is a rare tumor. A few cases have been reported in ovary. In case of male, a case of pure glandular endometrioid like yolk sac tumor is reported in a 43 years male in right undescended testis and another case of abdominal metastasis showing endometrioid pattern from mixed testicular germ cell tumor comprising of teratoma and embryonal carcinoma. My patient was a 20-year-old male presented with painless enlargement of right testis. Grossly the tumor was glistening creamish white with a multicystic appearance. Histopathological examination showed the tumor to be composed of glandular elements resembling early secretory endometrium, foci of keratinized thin squamous epithelium and a single focus of benign cartilage. The glandular elements show immunohistochemical positivity for AFP, cytokeratin 7 (CK7) and epithelial membrane antigen (EMA).

Brucellosis of Testis and Epididymis: A Review of the Literature.

Background: Brucellosis is a zoonotic disease which can afflict a number of organs and tissues. Brucellosis epididymo-orchitis (BEO), a complication of human brucellosis, can lead to other complications. In brucellosis non-endemic areas, some clinicians may be unfamiliar regarding the disease entity which may lead to delay in the diagnosis. Aims: To review the literature on BEO, in order to document its presentation, diagnosis, management and outcome following treatment. Methods: Various internet data bases were used to obtain literature on BEO. Results/Literature Review: BEO (epididymitis plus or minus orchitis) is a complication of brucella species which can be transmitted by direct contact through the respiratory tract, skin, or conjunctiva, and through the gastrointestinal tract after ingestion of unpasteurized milk/milk products or raw infected meat. BEO may in endemic areas affect 2 to 20% of patients with brucellosis but the disease can also be encountered sporadically globally in non-endemic areas. BEO may at times be bilateral. The presentation of BEO is non-specific and it may be mistaken for non-specific epididymo-orchitis or epididymitis or testicular tumour or abscess. Ultrasound and MRI scan findings are not specific to BEO. Diagnosis of BEO may be established by (a) history of contact, (b) cultures from blood/epididymal aspirations, (c) various types of laboratory studies including (I) Culture, (II) Polymerase chain reaction (PCR), and (III) serology. Laboratory criteria for the diagnosis of Brucellosis is divided into (I) those for presumptive diagnosis and (II) those for confirmatory diagnosis: BEO can be effectively treated by means of combination chemotherapy for about six weeks but at times ochidectomy or drainage of testicular collection may be required for persistence of symptoms or suspicion of a tumour/testicular abscess. Relapses can occur therefore careful follow-up is required. Conclusions: BEO can occur anywhere globally. A high index of suspicion is required from clinicians in order to establish early diagnosis. Most cases of BEO can be effectively treated with combination chemotherapy for about 6 weeks and triple antibiotic therapy would appear to be most effective and associated with absence or reduction of relapse.

Investigation of Gender Difference of Physiological Response in Gonadectomy in Sprague-Dawley (SD) Rats.

Aim: Sex hormones, including testosterone and estrogen, result in various pathophysiological changes in the body. To evaluate the pathophysiological changes following gonadectomy in male and female rats, we performed gonadectomy at the same age in male and female Sprague-Dawley (SD) rats. Methods: Male and female Sprague-Dawley rats castrated by bilaternal orchidectomy and ovariectomy at 6 weeks of age (six animals of each sex per group). Food intake, body weight, and clinical chemical parameters such as glucose, insulin, triglyceride and total cholesterol levels, were examined every 4 weeks from 8 to 40 weeks of age. Statistical analysis of differences between control and gonadectomized rats was performed using the F-test, followed by the Student’s t-test or Aspin-Welch’s t-test. Results: In orchidectomized (ORX) rats, food intakes and body weights were decreased, whereas in ovariectomized (OVX) rats, the body weights were significantly elevated without an obvious change in food intake. In clinical chemical analysis, hypercholesterolemia was observed in both ORX and OVX rats, but the triglyceride level was obviously decreased only in ORX rats during the observational period. In OVX rats, decrease of insulin sensitivity and significant increase of adipose tissue weights were observed. In bone metabolic analysis, bone mineral content in ORX rats and bone mineral density in OVX rats were decreased, respectively. Conclusion: Both orchidectomy and ovariectomy in rats affect glucose/lipid and bone metabolism, and especially, the glucose metabolism was deteriorated in OVX rats. Both male and female sex hormones play a key role in metabolic disease, such as diabetes, hyperlipidemia and osteoporosis.

Testicular Feminization Syndrome: A Case Study

We report a rare case of testicular feminization syndrome in a 24 years old patient. This is a syndrome due to androgen insensitivity. The patient is phenotypically female with male Karyotype (46XY). The patient is completely feminine with well-developed breasts, female external genitalia, blind vagina, absent mullerian structures, undescended testes and sparse axillary and pubic hair. The gonad (undescended testes) may be intra-abdominal, inguinal or labial. The patient was surgically treated with bilateral orchidectomy and vaginal reconstruction. The incidence of testicular feminization syndrome is reported to range from 1 in 2,000 to 1 in 62,400.

Assessment of a major depression animal model for old man established with orchidectomized plus olfacto-ry bulbectomized rat / 中华行为医学与脑科学杂志

Objective To evaluate the effectiveness of a major depression animal model for old man es?tablished with orchidectomized(ORX) and subsequently olfactory bulbectomized(OBX) rat. Methods Healthy Sprague?Dawley male adult rats were randomly assigned to six groups with ten rats in each group:intact,sham?oper?ated,model,vehicle,fluoxetine plus testosterone propionate(Flu+TP) and amitriptyline plus testosterone propionate (Ami+TP) groups. ORX+OBX rat model was established. Therapy of Flu or Ami (10 mg/kg,i.p.) combined with TP(25 mg/kg,s.c.) was administered. Behavioral changes of rats in each group were detected. Results Open field test: The number of rat crossing lattices in model((124.50±14.25)lattices) or vehicle group( 118.70± 10.27) was significantly larger than those of intact(38.20±6.30),sham?operated(33.70±9.58),Flu+TP (34.00± 9.82) and Ami+TP group (35.20±12.54). The rearing number of model or vehicle group was also significantly larger than those of intact,sham?operated,Flu+TP and Ami+TP group.Statistical differences in the above corre?sponding comparisons of open field test existed (P<0.01). Forced swimming test: The immobility time of model ((131.70±32.44)s) or vehicle group ((135.10±34.01)s) was significantly longer than those of intact((66.60± 12.06)s),sham?operated((62.00±13.38)s),Flu+TP((59.60±8.89)s) and Ami+TP group ((64.80±10.78)s). There were statistical differences in the above corresponding comparisons (P<0.01). Morris water maze test: The escape latency of model((62.00±26.05)s) or vehicle group ((60.52±27.00)s) was significantly longer than those of intact((24.19±9.12)s),sham?operated((21.06±8.13)s),Flu+TP((22.88±8.01)s) and Ami+TP group ((27.04±10.11)s);while the time rat swimming in the quadrant originally put a platform of model or vehicle group was significantly shorter than those of intact,sham?operated,Flu+TP and Ami+TP group. There were statisti?cal differences in the above corresponding comparisons of Morris water maze test (P<0. 01, P<0. 05 ) . Conclusion The above data demonstrates that ORX+OBX rat model is both repeatability and reliability,and can be a major depression animal model of old man for future researches.

Diagnosis and treatment of 17 primary testicular lymphoma cases / 国际外科学杂志

Objective Concluding the clinical feature and prognosis of primary testicular lymphoma to improve the understanding of this disease.Methods During 1995 and 2010,17 cases of primary testicular lymphoma treated in Beijing Friendship Hospital of Capital Medical University were retrospectively analyzed of its clinical features,diagnosis,treatment and prognosis.Results Seventeen patients with a mean age of 68 years complained the testicular sohd mass as their first symptoms.The mean tumor diameter was 4.7 cm,and all patients underwent orchidectomy,and testicular non- Hodgkin's lymphoma was confirmed by pathologic examination.Fourteen cases were diffuse large B cell type and 3 cases were anaplastic large cell type.The clinical stage of all the patients was IE.Fourteen cases were followed up (3 cases were lost)with mean follow-up time of 37.8 months by outpatient interview and telephone,all patients were treated with CHOP chemotherapy,and some of them were combined with rituximab and preventive lowdose pelvic radiotherapy.Five cases died of other chronic medical complications,1 case with contralateral testicular metastasis received surgery again.There were 9 tumor free survival cases in total.Conclusion Primary testicular lymphoma is rare and more common in older men.Postoperative pathologic diagnosis is gold standard.The systemic treatment and individual therapy is the first choice for primary testicular lymphoma.

Fournier’s Gangrene: A Case of Neglected Symptoms with Devastating Physical Loss

Fournier’s gangrene is a severe life-threatening infection involving the perianal area, perineum, and external genitalia. It demands prompt recognition, critical care therapy, surgical therapy, and a combination of antibiotics. The infection commonly spreads via the fascial planes and causes superficial vascular thrombosis within the Colles’ fascia around the external genitalia. It can extend cephalad to involve the Scarpa’s fascia and Camper’s fascia in the abdominal wall. The treatment would include multiple debridements, which would result in disfiguring scars of the perineum and might lead to significant physical and psychological complications. We describe a case of a 58-years-old man presenting with Fournier’s gangrene resulting from an infection of an impacted urethral stone. The patient previously had obstructive voiding symptoms for 1 month but chose to neglect them. The resultant infection was severe and caused penile and right testicular gangrene. He underwent multiple wound debridements, which included a total penectomy and right orchiectomy. Psychological and rehabilitative support was necessary for him to overcome his loss and disfigurement.

Locally Confined Primary Signet Ring Cell Carcinoma of the Prostate with Immunohistochemical Analysis.

A case of locally confined primary signet ring cell carcinoma of the prostate in an 85 years old male with complaints of retention of urine, dysuria and frequent nocturia is reported. On per rectal digital examination, hard nodular prostate of grade 3 enlargement was palpated. Serum prostate specific antigen (PSA) level was 33.7ng/ ml. Chest x-ray and computed tomography of the pelvis was negative for metastatic disease. Hematological and biochemical investigations were within normal limits. Transurethral prostatic biopsy was done and histopathology revealed the diagnosis of poorly differentiated adenocarcinoma. Transurethral resection of prostate (TURP) with bilateral orchidectomy along with radiotherapy was selected as modality of treatment. After histopathological examination of TURP specimen with Haematoxylin and Eosin (H & E) and Periodic acid Schiff (PAS) stain, a diagnosis of primary signet ring cell carcinoma of prostate was given which was confirmed by immunohistochemical analysis.

Genistein affects the morphology of pituitary ACTH cells and decreases circulating levels of ACTH and corticosterone in middle-aged male rats

The soybean phytoestrogen, genistein, is increasingly consumed as an alternative therapeutic for age-related diseases, namely cardiovascular conditions, cancer and osteoporosis. However, despite the beneficial effects on health, concern has been raised that this isoflavone also acts as an endocrine-disrupting chemical. The aim of this study was to examine the effects of genistein on immunohistomorphometric features of pituitary adrenocorticotropic cells (ACTH) and blood concentrations of ACTH and corticosterone in orchidectomized middle-aged male rats. Sixteen-month-old Wistar rats were divided into sham-operated (SO), orchidectomized (Orx) and genistein-treated orchidectomized (Orx+G) groups. Genistein (30mg/kg/day) was administered subcutaneously for three weeks, while the control groups received the vehicle alone. ACTH cells were identified by the peroxidase-antiperoxidase (PAP) immunohistochemical procedure. Circulating concentrations of ACTH and corticosterone were measured by immunoassay. Orchidectomy reduced (p<0.05) the cell volume and the relative volume of ACTH cells in comparison to SO rats. Genistein treatment further decreased (p<0.05) these morphometric parameters and reduced (p<0.05) circulating ACTH and corticosterone concentrations by more than 20 percent in comparison to both Orx and SO rats. In conclusión, genistein modulated the immunohistomorphometric features of ACTH cells and decreased blood ACTH and corticosterone levels, which supports evidence that this isoflavone affects the hypothalamic-pituitary-adrenal axis and suppresses glucocorticoid hormone secretion.

Evaluation of core and surface body temperatures, prevalence, onset, duration and severity of hot flashes in men after bilateral orchidectomy for prostate cancer

OBJECTIVE: To assess the prevalence, onset, duration and severity of hot flashes in men after bilateral orchidectomies (BO) for prostate cancer, to evaluate body temperature changes during hot flashes and to determine whether an elevated temperature within a few days after BO can be caused by deprivation of androgen. MATERIALS AND METHODS: Patients (n = 101) were questioned about the characteristics of their hot flashes after BO for prostate cancer. A subgroup of these men (n = 17) were instructed to record their oral and forehead temperatures during and at fixed intervals between hot flashes daily for 4 weeks. RESULTS: The mean age was 71.6 years, mean follow-up after BO was 33.2 months. Hot flashes were reported by 87 men (86 percent) with previous spontaneous remission in 9 (10 percent). The median time between BO and the onset of hot flashes was 21 days (range 1-730), median number of hot flashes 3 per day (range 1-20), and median duration was 120 seconds (range 5 to 1800). There was no significant difference between median oral (36.4º C) and forehead (36.0º C) temperature in the normal state, but during hot flashes the median forehead temperature (37.0º C) was higher than the oral temperature (36.5º C) (p = 0.0004). Both median oral and forehead temperatures were higher during hot flashes (36.5º C and 37.0º C) than in the normal state (36.4º C and 36.0º C, respectively) (p < 0.0001). During hot flashes, the oral temperature was 38º C to 40º C in only 3.2 percent of 593 readings in 17 patients. CONCLUSIONS: The median oral and forehead temperatures are higher during hot flashes than in normal periods. Oral temperature elevation > 38º C within days after a BO is unlikely to be the result of androgen deprivation alone.

Peripubertal orchidectomy transitorily affects age-associated thymic involution in rats

The role of gonadal hormones in induction and, particularly, maintenance/progression of rat thymic involution, which normally starts around puberty, was reassessed by examining the effects of peripubertal orchidectomy on thymic weight and morphometric parameters at different times up to the age of 10 months. Up to 6 months post-castration both thymic weight and cellularity in orchidectomized (Cx) rats were greater than in age-matched control rats, sham Cx (Sx). The increase in thymic cellularity reflected an increase in thymocyte proliferation rate (the proportion of proliferating cells was 18.6 ± 0.7 percent in 2-month-old Cx (N = 5) vs 13.4 ± 0.3 percent (N = 5) in age-matched Sx rats) followed by reduced sensitivity to apoptotic signals (apoptotic thymocytes were 9.8 ± 0.9 percent in 2-month-old Cx (N = 5) vs 15.5 ± 0.3 percent (N = 5) age-matched Sx rats). However, 9 months post-orchidectomy, neither thymic weight and cellularity nor any of the morphometric parameters analyzed differed between Cx and control rats. The reduction of thymic cellularity in Cx rats to control values may be related to increased sensitivity of their thymocytes to apoptotic signals in culture (72.6 ± 1.2 percent in 10-month-old vs 9.8 ± 0.9 percent in 2-month-old Cx rats) followed by reduced responsiveness to proliferative stimuli (14.1 ± 0.2 percent in 10-month-old vs 18.6 ± 0.7 percent in 2-month-old Cx rats). Thus, the study indicates that the effects of peripubertal orchidectomy on thymic weight and cellularity, as well as on the main morphometric indices, are long-lasting but not permanent, i.e., that removal of the testes can only postpone but not prevent age-related organ atrophy and consequently functional deterioration of the immune system.

Primary testicular non-Hodgkin's lymphoma: a review article

Primary testicular non-Hodgkin's lymphoma was first described as a clinical entity in 1866. It is a rare disease and accounts for 1 percent of all non-Hodgkin's lymphoma, 2 percent of all extranodal lymphomas and 5 percent of all testicular neoplasms. It is the most common testicular tumor in males between sixty and eighty years of age. Testicular non-Hodgkin's lymphoma is unique in its high incidence of bilateral involvement (8-38 percent), and it is also the most common bilateral testicular tumor. Testicular non-Hodgkin's lymphoma has a predilection for spreading to non-contiguous extranodal sites, especially the central nervous system. Advanced-stage disease is usually managed with doxorubicin-based chemotherapy. For early-stage disease, opinion is divided regarding systemic chemotherapy following orchidectomy. The high incidence of spreading, especially to the central nervous system, leads to advocacy of the use of central nervous system prophylaxis with intrathecal chemotherapy. Prospective multicenter trials incorporating a large number of patients may lead to better guidelines for optimal management of this subtype of non-Hodgkin's lymphoma.

O linfoma primário do testículo (LPT) foi descrito como uma entidade clínica pela primeira vez em 1866. É uma doença rara e corresponde a 1 por cento de todos os linfomas não-Hodgkin, 2 por cento de todos os linfomas extranodais e 5 por cento de todos as neoplasias testiculares. É o tumor testicular mais comum em homens entre 60 e 80 anos de idade. LPT é único em sua elevada incidência de envolvimento bilateral (8-38 por cento), sendo o tumor testicular bilateral mais comum. Tem uma predileção por disseminação para regiões extranodais não-contíguas, especialmente para o sistema nervoso central (SNC). Estágios avançados da doença são usualmente tratados com quimioterapia à base de doxorubicina. Para os estágios mais precoces, as opiniões são divergentes quanto à quimioterapia associada à orquiectomia. A alta prevalência de disseminação, especialmente para o SNC, sugere o uso de quimioterapia intratecal como profilaxia. Estudos prospectivos multicêntricos incluindo um grande número de pacientes poderiam resolver a questão com relação ao manejo deste subtipo de linfoma não-Hodgkin.
