Primary papillary serous carcinoma of the peritoneum is a rare primary tumor involving the peritoneum. Histologically, it is indistinguishable from serous ovarian papillary carcinoma, although it either spares the o-varies or only microscopically involves their surface. The characteristic features of this tumor are extensive peritoneal and omental masses or implants with psammomatous calcification, and ascites. In addition, it can occur focally in the pelvic peritoneum. We report the CT findings, with histopathologic correlation of primary papillary serous carcinoma of the peritoneum occurring in the upper mesorectum.

A lateral neck mass can be the initial presentation of a papillary thyroid carcinoma. A 24-year-old female presented with a 2.0 x 2.0 cm, non-erythematous, non-tender, right lateral neck mass. A neck ultrasound showed an enlarged right jugulodigastric (Level II) lymph node and a normal-sized thyroid gland exhibiting mild parenchymal disease with no nodules. Positron emission tomography-computed tomography scan (PET-CT) showed an enlarged intensely fluorodeoxyglucose (FDG)-avid right level III lymph node, which may be primary versus metastatic. Fine-needle aspiration biopsy (FNAB) of the lymph node showed the presence of atypical cells that are highly suspicious for metastatic carcinoma. A cervical lymph node excision biopsy was performed and histopathology showed metastatic papillary thyroid carcinoma. The patient underwent total thyroidectomy with neck dissection. The final histopathologic examination of the thyroid gland revealed chronic lymphocytic thyroiditis with the lymph nodes negative for metastasis. She eventually underwent radioactive iodine ablation (RAI) with a dose of 30mCi. Post-RAI whole-body scan showed functioning thyroid tissue remnants with no distant metastasis. This case adds to the limited data that ectopic thyroid carcinoma can be present in patients who initially present with neck masses.

Primary serous papillary carcinoma of peritoneum (PSCP) is a tumor of the peritoneum, distinct from malignant mesothelioma, but similar in many ways to primary epithelial ovarian carcinoma (EOC). It seems to be histologically identical to EOC and is differentiated from EOC based on the extent of gross ovarian involvement and microscopic invasion of the cortex. Currently, PSCP is evaluated, staged and treated in the same fashion as EOC, with the Gynecologic Oncology Group trials for the treatment of EOC now open to patients with PSCP. Therefore it is managed surgically in the same way as EOC with shared goal of optimal cytoreduction. Although the preponderance of evidence supports the benefit of maximal cytoreductive efforts for EOC, only limited data are available for debulking in PSCP. Here we report four cases of PSCP with a short literature, in who excisions of all visible implants were performed and residual lesions were measured up to less than 2 cm.
