Bilateral plasma cell mastitis simulating breast cancer: a case report and literature review.

Plasma cell mastitis (PCM) is a chronic inflammatory disease of the breast. It is a benign entity mainly found in nonpregnant and nonlactating women. PCM presents with symptoms of inflammation, breast erythema, masses, and indurations. We herein describe a 26-year-old woman with a 2-year history of right breast swelling and a 1-year history of left breast swelling during pregnancy and lactation. She was clinically diagnosed with bilateral breast cancer, but a biopsy specimen revealed PCM. During pregnancy and lactation, PCM can present as bilateral lesions. Early presentation and diagnosis are crucial because PCM, a benign disease, can lead to remarkable morbidity if allowed to progress to an advanced stage.

Jejunojejunal intussusception induced by a gastrointestinal stromal tumor: a case report and literature review.

Intussusception is defined as the invagination of a proximal segment of the bowel into the adjoining or distal segment. In most adults with intussusception, there is a demonstrable lead point with a definite pathologic abnormality. The clinical features of intussusception include chronic intermittent abdominal pain, nausea and vomiting, constipation, and a palpable abdominal mass. The present case report describes a 62-year-old woman with a 2-week history of abdominal pain and 9-day history of vomiting. Clinical, imaging, and histologic evaluations revealed a jejunojejunal intussusception with a gastrointestinal stromal tumor as the lead point. A gastrointestinal stromal tumor should be considered as a possible lead point in adult patients with intussusception. The implication of reducing the intussusception prior to tumor resection requires further evaluation in view of the risk of venous embolism, including direct spread of malignant cells, in cases involving a large polypoid mass with a necrotic surface that extends to the serosa as shown by intraoperative examination. Accordingly, the rationale for adjuvant therapy with imatinib also requires further evaluation.

Umbilical nodule, a rare presentation of primary cutaneous endometriosis: Case report and literature review.

Umbilical endometriosis or Villar's nodule is defined as the presence of endometrial tissue within the umbilicus and represent 0.5%-1% cases of endometriosis ectopia. It is classified as primary or secondary based on the surgical history. The important symptoms that characterize primary umbilical endometriosis were cyclical pain and a palpable mass that may be associated with bleeding. These features have temporal association with catamenia. Presented is a 30 year old woman with clinical features that suggested primary umbilical endometriosis in the past 5 years. It was confirmed by histology and coexisted with uterine fibroid. In the absence of previous surgery, primary umbilical endometriosis should be considered in the differential diagnosis in females of reproductive age with umbilical pain and nodule related to catamenia. Surgery is the treatment of choice and this should be individualized as some lesions can be managed by local excision with satisfactory outcome regarding the cessation of the presenting symptoms with good cosmetic outcome.

Large subserous uterine leiomyoma presenting as intraabdominal tumor: A case report.

Uterine leiomyomas are common benign gynecological tumors due to the overgrowth of uterine smooth muscle. Pedunculated uterine leiomyoma occurs when the mass is in continuity with the uterus with a stalk and may grow either within the uterine cavity or outside of the uterus and may mimic ovarian neoplasms or intraabdominal tumors. Presented is a 28-year-old woman with a progressive abdominal swelling in the past 9 months seen at the surgical outpatient of our facility. Preoperative CT suggested a diagnosis of an intrabdominal cystic. She had laparotomy and was offered myomectomies on account of a large subserous uterine mass arising from the right side of the uterine fundus, small subserous fundal mass, intramural mass in the left side of the fundus and a cervical mass. Histology confirmed multiple uterine leiomyomas with extensive cystic degenerative changes of the large subserous uterine myoma and adenomyosis of the left fundal mass. Detecting the continuity of an abdominal mass even with extensive degenerative changes mimicking a cyst in continuity with the uterus by a pedicle sign on imaging in the absence of ascites should arouse the diagnosis of pedunculated subserosal leiomyoma. This should be further heightened when it is found in association with cervical myoma. Subserous uterine leiomyoma should be considered in a patient of childbearing age with a grossly distended abdomen without obvious evidence of pregnancy or malignancy. Large subserous uterine leiomyoma in an intraabdominal location may present with diagnostic and surgical challenges that require interdisciplinary cooperation.
