[Ovarian and peritoneal sarcoidosis mimicking an ovarian cancer]

Falsely Elevated CA 15-3 Levels in Ovarian Sarcoidosis with Peritoneal Involvement and Ascites

A rare case of ovarian sarcoidosis with peritoneal and omental involvement presenting as an ovarian malignancy is presented. Clinical, laboratory, and radiological evaluation of the patient revealed ascites and high levels of serum CA 125 and CA 15.3. The diagnosis of sarcoidosis was confirmed with pathology findings on tissues obtained during surgical laparotomy. Establishing the diagnosis of sarcoidosis can be treacherous and was complicated in this case by the falsely elevated biomarkers and ascites.

Endometriosis resembling endometrial cancer in a postmenopausal patient

Endometriosis occurs in 2-4% of postmenopausal women. There have been a few reports of endometriosis in women in whom neither history nor diagnostic imaging indicated the presence of this disease, either at reproductive age or after menopause. A case is described of an 84-year-old patient with extensive deep pelvic endometriosis imitating advanced neoplastic process.

Uterine sarcoidosis: a rare extrapulmonary site of sarcoidosis

Sarcoidosis is a multisystem disease which is most commonly manifested in the pulmonary system. However, extrapulmonary manifestations have also been frequently reported. Isolated occurrence of sarcoidosis in the genital system is rare and poses a diagnostic and therapeutic dilemma. Uterine sarcoidosis can present with cervical erosions, endometrial polypoid lesions, and recurrent serometra. In majority of cases, it is diagnosed by endometrial curettage, but it has also been detected by examination of hysterectomy, polypectomy, and autopsy specimens. Nonnecrotizing granulomas are the characteristic pathologic finding of sarcoidosis. However, many infectious and noninfectious etiologies including certain neoplasms can produce similar granulomatous reactions in the female genital tract. These conditions affect the female genital tract more commonly than sarcoidosis, and therefore it is important to rule out these conditions first before making a diagnosis of sarcoidosis. Treatment of sarcoidosis is different from treating these other conditions and the most commonly used systemic or local corticosteroids can be hazardous if the underlying cause is infection. In this case report, the clinical presentation, histopathology, clinical course, and treatment of a patient with isolated uterine sarcoidosis are described, and a brief literature review of sarcoidosis of the female genital tract is provided.

Sarcoidosis mimicking metastatic gynaecological malignancies: a diagnostic and therapeutic challenge?

Several case reports describing the coexistence of sarcoidosis and malignancy have been published. Therefore, sarcoidosis should always be considered as a differential diagnosis when a cancer patient develops lymphadenopathy. Positron-emission tomography (PET) 2-[18F]-fluoro-2-deoxy-d-glucose (FDG) combined with computed tomography (CT) is widely used for cancer staging and surveillance because it permits localization of metabolically active malignant tissue. PET/CT or CT findings in patients with suspected cancer recurrence can be used to guide early and aggressive therapy. However, benign hypermetabolic lymphadenopathy can mimic malignant lymphadenopathy, both on a conventional CT scan and on PET/CT. Thus, it is important to obtain a histological diagnosis before initiating antineoplastic therapy based on imaging findings. Four cases of patients affected by gynaecological malignancies and coexisting sarcoidosis are reported in this study. Furthermore, the clinical relevance of making a differential diagnosis between gynaecological cancer recurrence and granulomatous disorder is given specific mention.
