UNLABELLED BACKGROUND To investigate the 3.0-Tesla (3 T) magnetic resonance imaging (MRI) characteristics of primary adnexal lesions for discriminating benign from malignant lesions. METHODS One hundred thirty-nine patients with pathologically proven primary adnexal masses referred for 3 T MRI assessment preoperatively were included. Baseline characteristics, components, and conventional M...
PURPOSE To externally validate and compare the performance of previously published diagnostic models developed to predict malignancy in adnexal masses. EXPERIMENTAL DESIGN We externally validated the diagnostic performance of 11 models developed by the International Ovarian Tumor Analysis (IOTA) group and 12 other (non-IOTA) models on 997 prospectively collected patients. The non-IOTA models ...
Desmoplastic trichoepithelioma (DTE) is a rare benign adnexal tumor with the characteristic features of asymptomatic, solitary, annular, indurated and centrally depressed papules or plaques, most commonly occurring in younger individuals on the face. Microscopically and clinically, DTE may be difficult to distinguish from other cutaneous adnexal neoplasms, particularly syringoma, cutaneous meta...
Syringomatous adenoma of the nipple (SAN) is an extremely rare disease originating in the adnexal gland; it was first reported by Rosen in 1983 [Am J Surg Pathol 1983;7:739-745]. Since then, 34 cases have been reported worldwide. We present the case of a 51-year-old man with SAN, in whom local excision of the tumor was performed. Histologically, the tumor consisted of tubules, ductules and epit...
Female Wolffian adnexal tumor (WAT) is a rare neoplasm arising from the remnants of the mesonephric duct and <100 cases have been reported globally. The present case report describes a 73-year-old female patient with WAT in the left ovary which, to the best of our knowledge, is the largest benign WAT tumor to be reported. In addition, the present case report reviewed previous studies on the cli...
Primary cutaneous apocrine carcinoma is a rare adnexal tumor of the skin that occurs mainly in the axilla, anogenital area while the scalp and the lower extremities, especially the thigh, are very unusual sites. However, clinical or pathologic characteristics have not been well established due to a paucity of this tumor. Herein, we report very unusual case of apocrine carcinoma present as a hug...
The aim of the present study was to determine risk factors associated with recurrence and survival in patients with grade 3 endometrioid endometrial carcinoma (G3EEC). A retrospective analysis of 117 patients with G3EEC, who were admitted to the Obstetrics and Gynecology Hospital of Fudan University between January 2000 and December 2011, was performed. The χ2 test or Fisher's exact test were u...
Eccrine spiradenoma is an uncommon benign adnexal tumor originating from the eccrine sweat gland. We diagnosed a eccrine spiradenoma on a 55-year-old man with histopathologic confirmation upon biopsy followed by complete resection, who had visited our clinic with a chief complain of occipital scalp mass. The solitary eccrine spiradenoma occurring in the scalp is rarely to be seen and should be ...
Spiradenoma & cylindroma are relatively uncommon sweat gland tumors. These lesions along with trichoepithelioma can co-exist and this gives support to the theory that they are part of the same spectrum and have a similar derivation.They can occur as separate lesions or within a single tumor mass as collision tumors.Here we report a case of a 67 year old female who presented with multiple papulo...
The primary neuroectodermal tumor of the ovary is extremely rare, and it manifests in 3 forms: differentiated, primitive, and anaplastic. The medulloblastoma belongs to the subgroup of primitive neuroectodermal tumor of the ovary. Only 3 cases of ovarian medulloblastoma have been reported in the literature, and all of them are presented without information about the specific pathological subtyp...
