Purpose To assess the prevalence of indeterminate adnexal cysts in women presenting to academic medical centers for pelvic ultrasonography (US), determine the incidence of malignancy, and identify cyst and patient characteristics that are predictive of malignancy. Materials and Methods A multicenter study of US-detected adnexal cysts with appropriate follow-up (surgical pathologic examination, imaging and/or clinical examination) was conducted from January 2008 to June 2012. Indeterminate cysts were classified as category 1 (typical benign appearing cysts >5 cm) or category 2 (cysts with avascular solid components) on the basis of a combination of definitions in the existing literature...

Eruptive syringoma is a rare variant of syringoma, benign neoplasms of the eccrine sweat ducts that appear on the face, neck, chest, and axillae of predominately Asian and African American women before or during puberty [1, 2]. Lesions appear as small skin-colored or slightly pigmented, flat-topped papules [2]. The condition can be cosmetically disfiguring and difficult to treat, especially in dark-skinned patients. The investigators report a 52-year old Guyanese woman who presented with widespread, chronic, non-pruritic and nontender, skin-colored papules that arose approximately 20 years earlier...

Tubular adenoma of the breast is one of the most rare benign neoplasms, accounting for only 0.13% to 1.7% of all breast benign tumors. Little is known about this rare neoplasm as the current literature offers only some case reports or a few number of small series. The aim of our study is to provide some clinicopathologic features of the breast tubular adenoma. We retrospectively analyzed at our department of pathology all cases of breast tubular adenomas confirmed by immunohistochemistry over a period of 9 years (2009-2017)...

Angiomyofibroblastoma (AMF) is a rare benign mesenchymal tumor with tendency to arise in the lower genital tract of middleaged women, predominately in the vulva. A few cases of AMF in males have been reported involving the scrotum, perineum or spermatic cord. We report a new case of AMF arising in the right inguinal region of a 27-year-old man. The tumor was well-circumscribed, myxoid and measured 30 mm in maximum dimension. On microscopic examination, the tumor was composed of spindle cells without atypia and with less than one mitosis figure per 10 high-power fields...

Non-functioning pituitary adenomas (NFA) are benign pituitary neoplasms not associated with clinical evidence of hormonal hypersecretion. A substantial number of patients with NFA have morbidities related to the tumor and possible recurrence(s), as well as to the treatments offered. Studies assessing the long-term mortality of patients with NFA are limited. Based on the published literature of the last two decades, overall, the standardized mortality ratios in this group suggest mortality higher than that of the general population with deaths attributed mainly to circulatory, respiratory and infectious causes...

The presence of enlarged epithelioid/spindled nests located deep in the reticular dermis of a biphasic melanocytic neoplasm can mimic melanoma arising in a preexisting nevus, causing over-interpretation of malignancy. We aimed to define the clinicopathologic significance of epithelioid/spindled nests in melanocytic nevi. Retrospectively using clinical and histologic information, we characterized 121 patients with a single lesion showing epithelioid/spindled melanocytes in the reticular dermis or subcutaneous fat, surrounded by melanophages, sometimes blending in with the adnexa...

BACKGROUND: Uterine leiomyomas represent the gynecological neoplasm with the highest prevalence worldwide. This apparently benign pathological entity may permeate into the venous system causing the so-called intravenous leiomyomatosis of the uterus (IVL). IVL may seldom extend to large caliber veins and reach the right cardiac chambers or pulmonary arteries and cause signs of right sided congestive heart failure and sudden death. Due to its low incidence, however, IVL with intracardiac extension is often misdiagnosed resulting in deferred treatment...

OBJECTIVES: To detect decreases in anogenital warts (AGW) among sex and age groups likely to be affected by human papillomavirus vaccination. METHODS: We estimated annual AGW prevalence during 2006 to 2014 using health care claims among US private health insurance enrollees aged 15 to 39 years. We derived AGW diagnoses using 1 of the following: (1) condylomata acuminata diagnosis, (2) viral wart diagnosis combined with a benign anogenital neoplasm diagnosis or destruction or excision of an anogenital lesion, or (3) AGW medication combined with a benign anogenital neoplasm diagnosis or destruction or excision of an anogenital lesion...

Phyllodes tumours (PTs) of the breast are uncommon fibroepithelial neoplasms comprising 0.3-1.0% of all primary breast tumours. The majority of PTs are benign and generally well managed with surgery. However, malignant PTs, and occasionally borderline PTs, can behave in a clinically aggressive manner by metastasizing to distant organs. Although distant metastasis is rare, the prognosis of patients with metastasis is dismal as many are unresponsive to standard chemotherapy and the risk of death is high. In this study, we correlated clinicopathological parameters to survival outcomes in a cohort of patients diagnosed with malignant PTs in our institution...

Fusion images of diffusion-weighted whole-body imaging with background body signal suppression and T2-weighted image (DWIBS/T2) demonstrate a strong signal for malignancies, with a high contrast against the surrounding tissues, and enable anatomical analysis. In the present study, DWIBS/T2 was compared with (18)F-fluorodeoxyglucose ((18)F-FDG) positron emission tomography/computed tomography (PET/CT) for diagnosing cancer in the abdomen. Patient records, including imaging results of examination conducted between November 2012 and May 2014, were analyzed retrospectively...

BACKGROUND: Noninvasive prenatal testing (NIPT) uses cell-free DNA (cfDNA)5 as an analyte to detect copy-number alterations in the fetal genome. Because maternal and fetal cfDNA contributions are comingled, changes in the maternal genome can manifest as abnormal NIPT results. Circulating tumor DNA (ctDNA) present in cases of maternal neoplasia has the potential to distort the NIPT readout to a degree that prevents interpretation, resulting in a nonreportable test result for fetal aneuploidy...

Naturally occurring mammary tumours are uncommon in prosimians. A 20-year-old female ring-tailed lemur (Lemur catta) developed bilateral enlargement of the mammary glands. Surgical removal revealed that both masses were comprised of multiple nodules and cystic areas that entirely replaced the normal glands. Histologically, a benign neoplastic biphasic cellular proliferation, composed of luminal-epithelial and basal-myoepithelial components, was identified. Immunohistochemical analysis for expression of cytokeratin (CK) AE1/AE3, CK7, CK5 + 8, CK14, vimentin, p63 and 14-3-3σ highlighted the biphasic nature of the neoplasm...

BACKGROUND: Mature teratomas, better known as dermoid cysts, are the most common ovarian neoplasms in women in the second and third decade of life. They are invariably benign, and most women are asymptomatic. Ovarian cystectomy is the preferred therapeutic option. CASE: A 24-year-old woman was planned for elective laparoscopic cystectomy for a suspected teratoma; operative findings led to a unilateral oophorectomy. Pathological analysis of the specimen revealed a focus of large cell lymphoma of unknown lineage arising in a mature cystic teratoma...

OBJECTIVE: To date, epidemiological evidence has consistently supported a link between ovarian cancer risk and menopause. However, little is known about how menopause status affects the risk of specific histological subtypes of ovarian tumors. We aimed to analyze the differences in various histopathological subtypes of ovarian tumors between pre- and postmenopausal women. METHODS: We reviewed the medical records of women who underwent surgery for ovarian tumors and received histopathological confirmation at the Busan Paik Hospital between January 1997 and October 2016...
