Features Aiding Differential Diagnosis of Ovarian Tumors

Appendix 1: Ovarian Tumors With Mucinous Epithelium Primary Tumors ■ Surface epithelial tumors Mucinous cystic tumors of intestinal and endocervical-like type Surface epithelial tumors of mixed cell type with a mucinous component Mixed müllerian tumors (adenofibroma, adenosarcoma, MMMT a a…

Tumor-like Lesions and Tumors of the Peritoneum (Non-müllerian)

Tumor-Like Lesions Inflammatory and Reparative Lesions Granulomatous Peritonitis ( Figs. 20.1–20.2 ) ▪ Granulomatous peritonitis, which can be caused by a variety of infectious and noninfectious agents, can result in peritoneal nodules, potentially mimicking disseminated cancer. Most of the following…

Endometriosis and Lesions of the Secondary Müllerian System

▪ Lesions considered here are characterized by müllerian differentiation on microscopic examination and reflect the metaplastic potential of the pelvic and lower abdominal mesothelium and the subjacent mesenchyme of females (‘secondary müllerian system’). ▪ The müllerian potential of these tissues…

Miscellaneous Primary Ovarian Tumors

Small Cell Carcinoma of Hypercalcemic Type Clinical features ▪ This tumor (SCCH) is the most common undifferentiated ovarian carcinoma in women <40 years of age. The age range has been 7 months to 44 years, with a peak from 18–30…

Sex Cord−Stromal and Steroid Cell Tumors of the Ovary

Sex Cord–Stromal Tumors ▪ These tumors (SCSTs), which account for ~5% of all primary ovarian tumors, are classified primarily on the basis of the constituent recognizable cell types ( Table 16.1 ): granulosa and theca cells, Sertoli cells, Leydig cells,…

Tumor-Like Lesions of the Ovary

Follicular Lesions Follicle Cyst Clinical features ■ Solitary follicle cysts (FCs) are most common in nonpregnant women of reproductive age, particularly around the menarche and menopause and are likely due to abnormal pituitary gonadotropin secretion, such as an FSH-secreting pituitary…
