Sex Cord Stromal Tumors

The research for the study of morphological, clinical and macroscopic characteristics of the different histological types of canine testicular tumors. Material was obtained during a routine surgery for the removal of testicular tumors in dogs in clinics of veterinary medicine in Kiev. Tumors were divided into sex-cord stromal tumors and germ cell tumors. Among the sex-cord stromal tumors recorded leydig (interstitial) and sertoli cell tumors. Macroscopical and histologic characteristics of canine interstitial (Leydig) cell tumor are described. It is 12.5% of all testicular tumors. The average age of dogs is 9 years. Largest share is breeds dog such as foxterriers and toyterriers. Interstitial (Leydig) cell tumor has a slower growth compared to other tumors the testicle, no metastases. Half the animals had no clinical signs. Mostinterstitial (Leydig) cell tumor go together with the pathology of adnexal structures. This is because Leydig cell tumor lead to increased levels of androgens. This fact may cause pathology of adnexal structures. Neoplasms are recorded both on the right and the left testis. Leydig cell tumor was not related to the cryptorchid testicles. Most tumors regular oval, brown or gray color, different texture and size with no signs of necrosis or ulceration. The average volume of tumors ranged from 2 to 20 cm2. Microscopically, the tumor is composed of cells that resemble Leydig cells and that are arranged into islands or tubular structures. Find polygonal eosinophilic cells with granular or vacuolated, which contains lipids. Nuclei were round mesh of chromatin and distinct nucleolus. Sometimes noted the large cells with 1, 2 or more nucleoli. In some cases, found elongated fusiform cells with small nuclei and granular eosinophilic cytoplasm. Tumor stroma characterized by calcification. Note mitotically active cells. Cysts lined by tumor cells are present in some tumors. Distinction between benign and malignant forms on purely histological criteria, in the absence of metastasis, often is difficult. Studies on the features of histological structure of testicular tumors will optimize the histological diagnosis of neoplasms.

Leydig Cell Tumors

Ovarian sex cord-stromal tumors arise from the stromal cells that surround and support the oocytes. Sertoli-Leydig cell tumors belong to this category of ovarian neoplasms. We present the case of a 38-year-old woman who was found to have a right ovarian mass. The mass was resected and diagnosed as Stage I Sertoli-Leydig cell tumor, retiform variant, following histopathologic and immunohistochemical examination. This case is unusual given the rarity of the retiform variant of Sertoli-Leydig cell tumor and the atypically older age of 38 years at presentation.

Abstract Although not required for the diagnosis, crystalloids of Reinke are pathognomonic for Leydig cell tumor. However, conventional frozen section rarely reveals their presence. A method of rapid identification of crystalloids of Reinke could improve the intraoperative diagnosis. We tested the efficacy of touch imprints and scrape smears for the identification of crystalloids in 2 cases of Leydig cell tumor of the testis. Intraoperative smears of the tumors yielded abundant crystals. Scrape cytologic testing was the better method. We speculate that the process of scraping, and to a lesser extent touch imprinting, disrupts the cytoplasm of the Leydig cells and releases the crystalloids. We conclude that cytologic testing is an effective method of identifying crystalloids of Reinke in Leydig cell tumors of the testis.

Malignant Leydig cell tumor (MLCT) is a rare testicular tumor in dogs. We report herein 2 dogs with MLCT and cutaneous metastasis. Grossly, marked enlargement and distortion of the involved testes were noted; on cut surface, the parenchyma was completely replaced by neoplastic tissue. In addition, these tumors had extensive necrosis and hemorrhage. Case 1 had a rapidly growing cutaneous mass in the left angle of the mouth; the lesion was well-circumscribed and had an indistinct lobular pattern. Case 2 had multiple cutaneous masses in the dorsal neck region, the thoracic back region, and the right hindlimb. Microscopically, the tumor lobules were composed of oval-to-polyhedral cells with eosinophilic cytoplasm and resembled testicular tumors. By immunohistochemistry, the neoplastic cells in both the testicular and cutaneous tumors were positive for inhibin-alpha and melan A. The mitotic counts of the primary tumors from cases 1 and 2 were 21 and 11 per 10 high-power fields, respectively. Based on these findings, the cases were diagnosed as MLCT with cutaneous metastasis. Ki-67 expression in the neoplastic cells of the 2 cases was higher than in benign Leydig cell tumors. Our findings may be helpful for the diagnosis of canine MLCT.

Sex Cord Stromal Tumors

Sertoli-Leydig cell tumor (SLCT) of ovary is an exceedingly unusual neoplasm that belongs to a group of sex cord-stromal tumors of ovary and accounts for less than 0.5% of all primary ovarian neoplasms. Very few case reports have been documented in the literature so far. Herein, we report a case of primary poorly differentiated ovarian Sertoli-Leydig cell tumor (SLCT) involving the left ovary in a 16-year-old single woman who presented with a 3-month history of a pelviabdominal mass, acne, hirsutism, and menstrual irregularities. In addition, a literature review on ovarian SLCTs is provided.

Abstract Introduction: Leydig stromal cell tumors are uncommon ovarian tumors that produce testosterone leading to hyperandrogenism. We present a case of a 63 year old lady with significantly elevated testosterone levels that did not have clear ovaries visualized on imaging, but was subsequently found to have a Leydig cell tumor on pathology after ovarian resection. Clinical Case: A 63 year old female with a past medical history of COPD, hypothyroidism, hyperlipidemia, hypertension and uterine fibroids status post hysterectomy and left oophorectomy in 1995 was referred to endocrinology for hirsutism. The patient reported first noticing abnormal hair growth approximately one year prior to presentation having developed increasingly coarse and thick facial hair, abdominal wall hair, and chest hair. On physical examination, she was noted to have coarse hair across her upper lip and chin continuous along the jawline along with fine, dark hair diffusely across her anterior abdomen. Initial laboratory cell evaluation revealed total testosterone 378 ng/dL, free testosterone 53ng/dL, DHEAS 64 ug/dL. Repeat labs drawn three months later confirmed the markedly elevated total testosterone of 362 ng/dL and free testosterone 44.2 ng/dL, concentrations normally seen in males. A CT scan of the abdomen and pelvis was done and did not reveal any masses. In addition, no ovaries were appreciated on imaging. A transvaginal ultrasound also did not reveal any clear ovaries. The patient ended up undergoing a right oophorectomy. Histological examination was consistent with a Leydig cell tumor. Following oophorectomy, her testosterone concentrations normalized (5ng/dL) and hirsutism began to regress. Clinical Lesson: Hyperandrogenism in women is typically classified into non-tumorous and tumorous. The differential for non-tumorous hyperandrogenism includes PCOS, congenital adrenal hyperplasia (CAH), and ovarian hyperthecosis. Tumorous causes include ovarian tumors such as Sertoli-Leydig cell tumors, hilus cell tumors, and theca cell tumors. Adrenal tumors secreting testosterone are extremely rare. Often with these tumors, there is significantly increased testosterone levels (> 140ng/dL) and rapid progression of symptoms. Sex cord stromal tumors account for only 5-8% of all ovarian tumors with Leydig stromal tumors a rare group that accounts for less than 0.1% of all ovarian tumors. The tumors are functional producing testosterone leading to marked hyperandrogenism and virilization. They are also usually benign and unilateral. This patient had hyperandrogenism manifested by hirsutism with markedly elevated testosterone concentrations. In addition, this case is unique in that a CT scan and transvaginal ultrasound did not clearly demonstrate her right ovary. Despite having a normal appearing right ovary during surgery, patient was found to have Leydig cell tumor following histological examination.

Aim: This study reports surgical treatment and its outcome for boys with a testicular tumor, in order to analyze the considerations of testis-sparing surgery (TSS) and investigate whether, in retrospect, treatment was according to a recently developed algorithm. Methods: We retrospectively reviewed boys with testicular tumors who underwent surgical treatment between January 2000 and June 2020 at the Wilhelmina’s Children’s Hospital and the Princess Máxima Center for Pediatric Oncology, The Netherlands. Medical records were searched for clinical characteristics and outcome. Results: We identified 31 boys (median age = 5.5 years) with a testicular tumor, 26 germ cell tumors (GCTs), four sex cord-stromal tumors, and one gonadoblastoma. Seventeen boys (median age = 1.5 years) had malignant and 14 (median age = 3.6 years) had benign tumors. Four boys with benign GCTs were treated with TSS, 25 with radical inguinal orchiectomy (RIO), and 2 with scrotal orchiectomy. No recurrence or testicular atrophy was reported. All boys with benign testicular tumors were treated as suggested by the algorithm, except for one boy treated with RIO. Conclusion: Retrospective analysis of surgical treatment of prepubertal boys with benign testicular tumors showed that TSS appears to be safe, and should be considered based on clinicoradiological data, in line with our algorithm.

Abstract Objective To evaluate the role of clinical features and preoperative measurement of cancer antigen 125 (CA125), human epididymis protein (HE4), and carcinoembryonic antigen (CEA) serum levels in women with benign and malignant non-epithelial ovarian tumors. Methods One hundred and nineteen consecutive women with germ cell, sex cord-stromal, and ovarian leiomyomas were included in this study. The preoperative levels of biomarkers were measured, and then surgery and histopathological analysis were performed. Information about the treatment and disease recurrence were obtained from the medical files of patients. Results Our sample included 71 women with germ cell tumors (64 benign and 7 malignant), 46 with sex cord-stromal tumors (32 benign and 14 malignant), and 2 with ovarian leiomyomas. Among benign germ cell tumors, 63 were mature teratomas, and, among malignant, four were immature teratomas. The most common tumors in the sex cord-stromal group were fibromas (benign) and granulosa cell tumor (malignant). The biomarker serum levels were not different among benign and malignant non-epithelial ovarian tumors. Fertility-sparing surgeries were performed in 5 (71.4%) women with malignant germ cell tumor. Eleven (78.6%) patients with malignant sex cord-stromal tumors were treated with fertility-sparing surgeries. Five women (71.4%) with germ cell tumors and only 1 (7.1%) with sex cord-stromal tumor were treated with chemotherapy. One woman with germ cell tumor recurred and died of the disease and one woman with sex cord-stromal tumor recurred. Conclusion Non-epithelial ovarian tumors were benign in the majority of cases, and the malignant cases were diagnosed at initial stages with good prognosis. The measurements of CA125, HE4, and CEA serum levels were not useful in the preoperative diagnosis of these tumors.
