This study aimed to evaluate the clinicopathological features of ovarian seromucinous borderline tumors (SMBTs) and mucinous borderline tumors (MBTs) and to establish a diagnostic approach using immunohistochemistry (IHC) and Alcian Blue-Pe…

OBJECTIVES: Cervical adenocarcinoma has been increasing in frequency, particularly among young women. Its diagnosis still presents many challenges. In addition to the difficulty in accessing the lesion, the lack of well-established criteria…

BACKGROUND: Focal liver lesions with spindle cell morphology are rare in the daily practice of pathology. The differential diagnosis is broad, including both tumors and tumor-like lesions. Initial radiologic assessment is sometimes inaccura…

The gold standard for diagnosing endometriosis is by laparoscopic visual demonstration of ectopic endometrial lesions outside the uterus, preferably verified by biopsy and microscopical examination. Molecular markers to facilitate the micro…

It has been suggested that impaired venous drainage and endometrial vascular ectasia (EMVE), secondary to increased intramural pressure, explains abnormal bleeding in fibroid uteri. Striking EMVE with extravasated red blood cells (ecchymosi…

Management of malignant urothelial tumors is often associated with extended costly treatments, some with significant morbidity. Advanced tumors are treated with radical cystectomy with neoadjuvant or adjuvant radiation or chemotherapy. Over…

BACKGROUND: Seromucinous ovarian tumors are rare and not adequately described in the literature and this is especially true for seromucinous carcinomas. AIM OF THE STUDY: To describe histological and clinical features of these tumors in co…

Thoracic endometriosis is defined as the ectopic presence of endometrial glands and stroma in lung or pleura and constitutes an uncommon cause of spontaneous pneumothorax in nonsmoker women in childbearing age. From 2000 to 2014, 18 (7.3%) …

We aimed to investigate the prevalence and spectrum of unusual benign neoplasms and tumor-like lesions presenting as vulvar polyps and papules, to study their clinical, pathologic, hormonal, and developmental features and whether they have …

We encountered 2 unusual cases of polypoid endometriosis presenting as unilateral ovarian masses. The first was benign and was found in a 57-year-old postmenopausal patient; the second case gave rise to well-differentiated endometrioid carc…

We present a 58-year-old woman with primary squamous carcinoma of the ovary likely arising from a monodermal cystic mucinous teratoma. Noninvolved ovary showed no Brenner tumor, endometriosis, transitional carcinoma, endometrioid adenocarci…

Atypical glandular cells of undetermined significance (AGUS) is a diagnostic category of the Bethesda system encompassing glandular-type cells that show either endometrial or endocervical differentiation and display greater atypia than expe…
