Primary Peritoneal Serous Papillary Carcinoma Presenting as a Single Colonic Mass without Peritoneal Dissemination

Abstract

Peritoneal serous papillary carcinoma (PSPC), a rare primary malignancy arising from the abdominal and pelvic peritoneum, is characterized by peritoneal carcinomatosis with ascites and a histological pattern similar to that of papillary serous ovarian carcinoma. We herein describe a rare case of PSPC with unusual clinical presentations involving a single primary tumor originating from the peritoneal lining of the sigmoid colon with no evidence of intraperitoneal spread, pelvic lymph node involvement or distant metastasis. Awareness of such unusual presentations of PSPC should assist in the diagnosis of this disease, thereby improving the management of patients with this condition.

Inguinal Lymph Node Metastasis of a Primary Serous Papillary Carcinoma of the Peritoneum One Year after CRS and HIPEC

“…It has shown a variety of clinical presentation and spreading patterns. Ranging from a single colonic mass [13] to distant lymph nodes without intraperitoneal dissemination [14], the understanding of the clinicopathological behavior of PPSPC has been much of a challenge.…”

A rare cause of jejunal wall thickening: Primary peritoneal serous papillary carcinoma

“…PSPK, nadiren de olsa intestinal duvarı invaze ederek intestinal kitlelere neden olabilmektedir. Literatürde günümüze kadar kolonda kitle (kolon karsinomu) ile prezente olan ve kötü diferansiye PSPK tanısı konulan yalnızca 3 olgu bildirilmiş olup ince bağırsak tutulumu şu ana kadar hiç bildirilmemiştir (12)(13)(14). Bizim olgumuzda PSPK'un jejunum orta kısmından başlayıp ileal duvarı yaygın bir şekilde infiltre ettiği gözlendi.…”

An unusual cancer involving the rectum: two cases of localized primary peritoneal carcinoma mimicking rectal carcinoma

“…Patients may present with abdominal swelling, constipation, gastrointestinal disorders, nausea, vomiting, anorexia, and weight loss. Localized presentation of PPC is rare, with only a few cases reported in the literature [1][2][3][4]. Our paper describes two patients with locally invasive primary peritoneal cancer arising from the pouch of Douglas peritoneum presenting with predominantly bowel symptoms mimicking rectal carcinoma.…”

“…Primary peritoneal cancer presenting in this manner is exceedingly rare with only a few cases previously reported in the literature [1][2][3][4]. Diagnosis is challenging as the symptoms of tenesmus and hematochezia mimic rectal tumors such as primary rectal carcinoma, gastrointestinal stromal tumor (GIST), and sarcoma.…”
