1/68. Unusual sonographic appearance of an epidermoid cyst of the testis.Epidermoid cyst of the testis is a rare benign testicular tumor with varied sonographic appearances. We present a case in which two specific ultrasonographic patterns were seen: (1) an "onion ring" configuration of alternating hyperechoic and hypoechoic regions, described previously as being characteristic of this lesion, and (2) a heterogeneous region with multiple punctate hyperechoic foci.- - - - - - - - - - ranking = 1keywords = testis (Clic here for more details about this article) |
2/68. Ultrasound of testicular epidermoid cysts.The ultrasound findings of focal intratesticular lesions may sometimes be characteristic of benign pathology, which accounts for approximately 5% of all testicular tumours. Three cases of epidermoid cysts of the testis are presented along with a review of the literature. Recognition of the typical ultrasound appearances of this entity in a clinical situation of painless testicular swelling in the absence of a history of trauma and signs of inflammation can make testis-sparing surgery feasible.- - - - - - - - - - ranking = 0.4keywords = testis (Clic here for more details about this article) |
3/68. Calcified epidermoid cyst in the testis: an unusual finding on ultrasound.Epidermoid cysts of the testis are uncommon, benign testicular tumours. They are often seen on ultrasound as rounded, hypoechoic lesions due to high keratin contents. Calcification within epidermoid cysts is rare. We report a case of prominent calcifications within an epidermoid cyst. If a possible epidermoid cyst is identified with ultrasound, testis-sparing surgery should be considered.- - - - - - - - - - ranking = 1.2keywords = testis (Clic here for more details about this article) |
4/68. Intratesticular epidermoid cyst. A rare benign tumor.Epidermoid cysts rarely arise within the testis. The incidental discovery of a distinct, intratesticular epidermoid cyst in a nineteen-year-old man is reported. Management by radical orchiectomy is stressed because grossly the tumor is indistinguishable from a malignant testicular tumor.- - - - - - - - - - ranking = 0.2keywords = testis (Clic here for more details about this article) |
5/68. Malignant proliferating trichilemmal tumor.Proliferating trichilemmal tumors are uncommon neoplasms that are usually benign, but characterized by frequent local recurrence. In this report, we describe a patient who sought treatment at our clinic for a right occiput scalp nodule measuring 1 cm in diameter. The subcutaneous lesion was mobile and without overlying skin ulceration. Excisional biopsy of the mass was performed and the pathologic diagnosis returned as malignant, proliferating trichilemmal (pilar) tumor. Resection margins were free of tumor. On further examination the patient had no evidence of metastatic disease. A schedule of routine follow-up visits was arranged to monitor the site for recurrent disease.- - - - - - - - - - ranking = 0.00012796445813812keywords = neoplasm (Clic here for more details about this article) |
6/68. Squamous cell liver cancer arising from an epidermoid cyst.Squamous cell liver cancer (SCLC) arising from an epidermoid intestinal cyst is rare. Only 65 cases of this cyst have been reported since 1850, with 2 reported cases of squamous cell cancer. We describe here the case of a 21-year-old man who complained of mild pain, a feeling of fullness in the right upper quadrant of the abdomen, and fever and weight loss, who developed SCLC arising from an epidermoid intestinal cyst. The clinical presentation, management, and pathological findings are discussed.- - - - - - - - - - ranking = 0.001936674150343keywords = cancer (Clic here for more details about this article) |
7/68. Epidermoid cyst of the testis in an adolescent: Case report and review of the evolution of the surgical management.Epidermoid cyst, a tumorlike lesion, is a rare benign testicular tumor with typical, distinctive ultrasonographic appearance. When the preoperative features are highly suggestive of epidermoid cyst, testicular sparing surgery after strict oncologic guidelines is warranted. The authors report a case of a preoperatively suspected epidermoid cyst in an adolescent and review the literature concerning the changing paradigm of management.- - - - - - - - - - ranking = 0.8keywords = testis (Clic here for more details about this article) |
8/68. Solitary fibrous tumor of the skin.Solitary fibrous tumor (SFT) is an uncommon tumor initially reported in the pleura but recently described in other sites of the body. We report a SFT of the skin that presented as painless nodule located in the right cheek in a 56-year-old woman. Histologically, the tumor was composed of spindle-shaped cells arranged in a patternless pattern of short and narrow fascicles with interspersed bundles of thick collagen, and numerous blood vessels with a focally hemangiopericytoma-like appearance. Immunohistochemically, the tumor cells strongly expressed vimentin, CD34 and bcl-2. The lesion was excised and the patient remains well at 16-month follow-up. This case presented some diagnostic difficulty because of its unusual location, and had to be distinguished from other superficial soft tissue tumors. Recognition of SFT in the skin is important to avoid possible confusion with a variety of spindle cell neoplasms with different biologic potential.- - - - - - - - - - ranking = 0.00012796445813812keywords = neoplasm (Clic here for more details about this article) |
9/68. Clitoral cyst as a cause of ambiguous genitalia.BACKGROUND: Ambiguous genitalia need appropriate evaluation, because a serious disease can manifest as this condition. CASE: A 28-year-old woman was referred with a "penis" present from age 12 years that enlarged throughout puberty but recently was unchanged. Differential diagnosis included true hermaphroditism; adrenal hyperplasia; clitoral, ovarian, and adrenal neoplasms; stromal hyperthecosis; polycystic ovarian syndrome; and exogenous androgen exposure. Free testosterone was not elevated. dehydroepiandrosterone sulfate, 17-hydroxyprogesterone, total testosterone, androstenedione, deoxycorticosterone, 11-deoxycortisol, chromosomal analysis (46,XX), an intravenous pyelogram, and pelvic ultrasound were normal. The patient elected surgical removal. The mass was a chronic inflamed epidermoid cyst. CONCLUSION: If this patient had been appropriately evaluated earlier, she would have been spared anxiety and embarrassment over a simple epidermoid cyst.- - - - - - - - - - ranking = 0.00012796445813812keywords = neoplasm (Clic here for more details about this article) |
10/68. Multiple epidermoid cysts arising in a cryptorchid testis following ochiopexy.Epidermoid cysts of the testis are rare benign intratesticular lesions, representing about 1-2% of all intratesticular tumors. In the English literature, the total reported number of patients with an epidermoid cyst is approximately 300. Almost all of the previous reports were of a single lesion in a testis and the occurrence of epidermoid cysts in cryptorchid testis was extremely rare. Herein, we report on a patient with multiple epidermoid cysts in a cryptorchid testis following orchiopexy. Because the cysts arose in a cryptorchid testis and occupied most of the space of the testis, orchiectomy was performed.- - - - - - - - - - ranking = 2keywords = testis (Clic here for more details about this article) |
